Past two decades, granite has become the most fashionable one of building and furnishing materials, the appearance of its natural simplicity is difficult to compare with other decorative materials. However, the granite has not previously been expected "problems" are now more and more apparent. For example, often see granite rust, organic stains, water stains and water spots, salt and white spots of China, the surface loss of light and oil spots and so on. These problems undermine the original granite decorative effect, and clear marble with considerable difficulty, as they had penetrated the porous granite gap, not an ordinary scrubbing can remove the surface, while heavy equipment is destroyed considerable cost. Thus, the appropriate cleaning and control techniques have emerged. Special cleaning agents granite granite industry has become an indispensable branch of the field, revealing to the concept of economic prospects. At present, the development of granite cleaning agents, production and use still in its infancy, as soon as possible to regulate granite cleaning agent for the detection and evaluation methods of granite cleaning industry is of great significance. This is only an exploration, within and outside the industry for reference.
1, the classification of granite cleaning Mosaic
granite cleaning agents can be divided according to form: Liquid, aerosol type, powder type, etc.;
Can be divided according to the nature of the solvent: water formulations, solvent type, emulsion, gel, etc.;
According to the pH of cleaning agent can be divided into: acidic type of neutral, alkaline-type, etc.;
Cleaning can also be subjects were divided into: Remove all dirt (inorganic impurities such as rust, ink, Chinese white, salt spots, water spots, etc.; organic dirt, such as oil spots, tea trace, biological pigments, etc.) of the special cleaning agent .
Because the reasons for the formation of surface dirt granite vary, the appropriate role of the principle of cleaning agents and the use of methods must be different. Therefore, the granite must indicate type of cleaning agents, especially cleaning of the objects and conditions, and details are used.
Clearly, unlike the granite cleaner protectant, it is difficult there is no need to harmonize all the technical requirements. Different cleaning agents according to their basic performance characteristics of the determination and decontamination capabilities. Determination is to ensure that the basic properties of the granite, the environment, humans, decontamination capability determination is to determine the cleaning effect of cleaning agent.
2, the basic performance Slate
The basic properties of granite cleaning agents, including physical and chemical traits. Mainly due:
(1) Appearance: liquid detergent products (slurry products) should not be hierarchical, non-suspended solids or sediment; aerosol products should not be apparent separation; powdered product should not be agglomerated. This is to determine whether the product is the most basic method of deterioration.
(2) Odor: cleaning agent should be no similar benzene, kerosene, fishy, spicy or pungent odor, and should not be left to clean the granite was the smell. This is to determine whether the product has contaminated most basic ways.
(3) to clear: when to use water when cleaning or other cleaning materials, cleaning agents and the role of the product should be completely removed. This is to determine whether the product will be left of the most basic ways.
(4) Flash point: The flash point of solvent-based products must be determined, according to ASTM-D39 specific determination. This product is flammable and explosive is to determine the most basic ways.
(5) pH value is measured: at room temperature, measured with a pH value of the stock solution and the use of the cleaning agent concentration, pH value (accurate to 0.1pH), marked.
(6) Stability: Stability of the lotion is to see the stability of high or low temperature: the liquid cleaning agent into a clean 60ml glass reagent bottle, placed in 40 ± 1 ℃ oven or a 3 ~ a 10 ~ (2 refrigerator, 24h, remove, place the indoor return to room temperature, check its appearance and smell, and determination than before to be basically unchanged.
(7) toxicity: the safety. Cleaning agent raw materials should not contain highly toxic materials, such as hydrofluoric acid. Cleaning agents for the human body and the environment is a very important issue, recently took place on the external walls of a city in Zhejiang cleaning agent pour in the human body and poisoning deaths. granite cleaning agent toxicity may arise on the skin, mucous membranes and respiratory system and other parts of the stimulation, damage, and can cause harm to the environment with reference to the Ministry of Health determined the detection of environmental disinfectant (or reference to the recent publication of the American Medical Association Determination of Environmental Health files). At present, China-related toxicity testing cleaning agent is still the weak link in the light of the detection method can be very small. As for the human, biological and environmental risks and negative effects will be increasingly attracted attention, forward-looking granite cleaning agent in the specification included in the cleaning agent toxicity testing and evaluation methods is necessary.
3, the cleaning agent decontamination ability of the detection method
3.1 Preparation of samples of granite
Vary the actual stain, in order to facilitate the cleaning agent in the laboratory assessment of the decontamination effect, the first granite should be uniform smear specimen preparation laboratory. granite common stains are: rust, Bai Hua (alkaline spots). Water spots. Organic stains (tea, coffee, straw yellow, excretion or decay of biological material, etc.). Oil spots (including lipids and waxes. Into mineral, plant, animal). Cement spots, glue or bonding agent. Aged dust, dirt. Ink and other chemical impurities, such as microbial scar. Artificial parts of the actual preparation of the stains and dirt will have a certain gap, in order to ensure the consistency of the standard laboratory method of preparation of smear samples should be representative, and the more realistic the better. We already have a method of production of such stains, due to space relations, and is not described.
3.2 sample cleaning steps
As the dirt and granite variety of cleaning agents, the use of different methods, it is difficult to unity cleaning steps, generally used only in accordance with the manufacturer's instructions described methods. In order to effect a more scientific assessment of decontamination is required to set;
(1) blank sample: that is, without stains do not wash the same kind of granite-like, as a cleaning, washing and residual factors comparable reference material;
(2) blank cleaning sample: that is, without stains, but cleaning the same kind of the same granite, to compare the cleaning of the granite appearance and surface morphology;
(3) Reference sample: that is stain and only kind of cleaning agent like granite cleaning solvent to ensure the credibility of artificial stains. In addition, the cleaning of granite stain test sample requires at least three parallel samples in order to reduce random error.
3.3 The inspection and evaluation of cleaning effect
granite cleaning effect of the test and evaluation includes two aspects to improve the appearance, the second is to improve the surface characteristics (especially the cleaning of granite artifacts to be inspected and assessment). It should be noted that, as far as possible to determine numerical order to reduce the influence of human factors.

marble dyeing has formed industrial chain
"Say natural marble, surfacing in Spanish cream-colored, less than six months after sitting room in white became seriously fade hut." A few days ago, east lake li island village owner came to express the Mr. 2001 the newsroom, brought home "a small piece of marble, let reporters please experts identify once, see if after artificially dyeing. Reporter interviewed concerned professionals, learned that natural marble dyeing is already industry "routine". In order to look good or makes a heftier profit of the marble quotient of reactive dye already "proficient", and they have already formed industrial chain, consumer health behind.
Market marble dyeing phenomenon stone
Reporters in the east part of building materials supermarket recently visited discovered that, the marble marble material price from every square metre 92 yuan to 23000 dollars, name multifarious, what sand Anna cream-colored, Spain cream-colored, India red, Norwegian red, white, sir ShuGua ice, the Venus etc., let dilettante consumer baffled, but in the sale nearly 70% marble inn-keeper claimed to be natural marble. In a sale of the Spanish cream-colored marble, reporter consulting stores is the product of natural marble. "100% natural marble, such as false buy a penalty ten." answer very sure. Reporters asked, heard that natural marble will dyeing, what is this? This name, not eliminate others admit a false, but the essence of natural marble or quarry. A consumer tells a reporter, marble how have so many colors, a see be do color. And the price is very untidy, the same texture marble on the different color became import marble material to eight times, prices will vary. This want to shop at home, because the marble guest restaurant is going to use color is too fake floor.
marble dyeing has formed industrial chain
Natural marble is how to dyeing? Through a person familiar with the phone, journalist and provide a chemical enterprise in hebei shijiazhuang contact, said they were doing marble business, suffer from tonal single, business is not ideal, intendsto cooperate marble dyeing matters. Each other a head of the name beams without reservation, said they generally introduced in accordance with the following process dyed, before being dyed in marble in drying stove first roasted, after 48 hours at room temperature cooling out; Will classics drying and the cooling of the marble put in by after-chroming dyed pool, will, dyed pool into first dyeing namely coarse dye; Then will coarse dye and dries marble add drying stove in the second baking; Then put the cooling of the marble again into dyed pool on the second dyeing namely fine dye; He dyed and confirmed by the cooling of the marble again into the pool of pure dye the third dyed; The essence of dyed and natural drying on the marble surface treatment, and paraffin grinding and cutting into finished products. Ingredients include dye of benzene 2 amine, aniline, sodium chloride, nitric acid manganese etc. As for whether harmful to human body dye, beams, and not to eat into said belly, setup time long it's ok. According to understand, shandong, zhejiang, guangdong, place and many such professional "dyeing".
Learn to identify colored lubricious marble
So, natural marble what harm to human body Slate? Jiangsu qualitative inspect branch related technical personnel told reporters, lately they received some consumers strains suspected dyeing natural marble, test results indicate that the marble material of dyed color in formaldehyde, mercury, lead etc generally content exceeds bid badly. If installation indoors, human body long time of health has certain harm contact. So how to discern dyeing of natural marble? The technical personnel introduces said, dyeing marble color more bright-coloured, but not the nature; Paper in surface scrubbed hard fall, such as color is dyeing marble; The fracture in marble material can be seen at the levels, dyeing penetration Dyeing marble generally USES the rocky is bad, porosity, bibulous rate is high, the marble with percussion method can distinguish, sounds of fake dyeing of marble sound more tedious; Dyeing marble often besmear to add luster, oil waxes are oily be soiled feeling, its rear with micro fire like roast, wax surface loses, reveal original face; Film, although the marble material of high gloss, but film, insufficient strength, light wear easily see have scratch etc.

improve production safety measures small quarry
The standardization of safe marble quarry not only the comprehensive utilization of mineral resources development, rational exploitation and realization of economic quarry, an important prerequisite for safe production, but also protect the interests of production and operation and an important foundation to maximize social benefits. Therefore, the doubly by the government and relevant departments, social, and quarry owners of the great attention and concern. Therefore, we should actively promote the standardization of the quarry.
3.1 unified planning, scientific distribution, rational exploitation of a
According to "People's Republic of mineral resources exploration and the" People's Republic of feet and other safety regulations, the resources of the proposed quarry reserves, the mine site selection, mining area, geological and mining conditions of safety and the period of strict inspection demonstration. Special work by deepening the mine opportunity to convene the relevant government departments, according to granite demand for marble, rational utilization of mineral resources, environmental protection, production safety conditions and other factors, unified planning, scientific distribution and rational exploitation. Out of small-scale waste of resources, the irrational distribution, environmental destruction, and does not have the marble field of production safety conditions, and promote rational use of resources to the larger, better safety conditions for the field of marble size and quality.
3.2 The integration of enterprises, the scale mining
Owners for the same number of mining and mining surface mining permit number of the owners mining the same phenomenon, by mining the quarry face in accordance with the small capital, resources and other production elements integration of enterprises according to their choice of Yin or partnership were to integrate to become a legal entity. A mining enterprise sub-surface can only be carried out by a mining enterprise unified management, unified production and unified security management. Expand the production scale of the quarry, out and off do not have basic conditions for the safe production of small quarries, a fundamental solution to the disputes between enterprises, mining and quarry interference of small scale enterprises, security risk management are not situation.
Mining 3.3 standardized to promote the management of the quarry
First, non-coal mine production safety special rectification work. Lang door should be developed on a positive industrial policy to guide the township (town), village collective and the individual joint quarry, restructuring, expansion of the quarry to scale. Increase production capacity. Meanwhile, the land and resources should be integrated planning and rational distribution and exploitation of mineral resources exploitation point scale, to achieve large-scale mining.
Second, to allow sub to play the leading role of the government and relevant departments, clearly quarry security technology-oriented to strengthen the coordination of technology to promote the safety of quarry mining input, integrated society, enterprises and intermediary organizations, talent , technical and financial advantages, the use of advanced mining technology controlled blasting techniques and to promote the standardization of different types of stope new methods of mining.
Third, according to non-coal mine safety production situation assessment, establishing a standardized model mining area, demonstration sites. Mainly with the size of the quarry, economic, technological, topographical, geological and other conditions, choose a group of good economic fundamentals and technical conditions for the quarry, and gradually the pilot, promoting the existing hole Blasting in the high stage small-layered, irregular small step Blasting, Blasting Rules and other small steps to achieve "top-down, sub-level mining" method, in order to point the form to use, and promote advanced mining technology atmosphere, and comprehensively promote the technical level of the quarry, mining operation and production equipment, standard operating conditions of harmony.
Fourth, to strengthen the person in charge of the quarry, production management and workers of the basic knowledge and blasting safety management and technical training, take full advantage of training courses, on-site meetings, etc., with the typical sub-level mining experience and practice, experience points level exploitation of the economic and security advantages of technology to guide the application of advanced blasting quarry, driving the overall sub-level mining technology promotion.
3.4 Improved mining technology, adhere to safety first
Most of the existing quarry mining technology hole drilling rig use of desktop, desktop rig structure from the device only from the middle or bottom of the rock drilling, they then burst, Xu is a violation of, non-metallic surface mine safety regulations standards and extravagant gown town quarries safety requirement ", causing the umbrella canopies, dig hole mining. Therefore, desktop rig and processes must be eliminated in favor of a pneumatic drill or a vertical drilling rig to a top-down according to standard mining. Meanwhile, the development assessment requirements for artillery work, where the facilities caused by blasting operations umbrella canopies, dig hole formation, will be dealt with until the revocation of certificates. Quarry owners to encourage investment in mechanized mining to minimize the input of labor to reduce casualties.
3.5 establish a sound regulatory mechanism
Establish and improve production safety supervision mechanism is to solve the quarry and other production units of production safety work "does not go on the implementation and strict non-up" phenomenon and the key to achieving lasting peace and stability safety. Current potential accidents blitz of "carpet-style" check, although the concentration and control of potential accident played a role, but often stop-gap measures. To achieve fundamental improvement in safety, must be innovative regulatory mechanisms and means to establish long-term mechanism of production safety, covering the comprehensive, dynamic management, long-term effective protection of a strong regulatory system.
3.6 improve security and emergency rescue system to improve the ability to respond to security incidents
Timely emergency response is critical to reduce loss of life and property. A small quarry on the remote is particularly important. Therefore, the city should develop and improve as soon as possible major emergency mine rescue teams, once the quarry landslide collapse accident occurred, the rescue quickly rushed to the scene to reduce casualties.
4, improve the significance of small and medium sized quarry safety
Quarrying industry is one of the important Slate industries, infrastructure construction in China, has a pivotal role. As China's deepening economic reform and opening-up, rapid economic quarrying promote the rapid development, especially rural collective quarrying, and more flourishing at an unprecedented rate, for the transportation, construction, tourism development of arrangements for the employment of rural surplus labor force, promote and maintain stability and make a great contribution.

Proper use of oil briefly the method of granite Protectant
granite has a porous, so need to be sealed after installation. You may request professional, also make your own. Here are some of the knowledge sealing granite countertops.
Before sealing
Note: Not all are required to seal the granite countertops. So how do you judge to be not sealing it? To be a simple test: a few drops of water to the granite countertop. Penetrate into the surface of the water table records the time. If the penetration of less than 3,4 minutes used, it shows that granite countertops need to seal. Longer if you do not need penetration seal.
You can also drop two drops to a granite countertop, about 30 minutes after the wipe. If the granite has been completely sealed there will be no water damage. If you need to seal water-soaked.
Osmotic protective agent
Osmotic protective agent is oily, so they penetrate deeper, faster, and protect the structure of granite and other natural stone effect. These oily protectants protected "from the inside out." They are easy to use, so you can seal it yourself. Osmotic protective agent spread directly from the granite surface, preferably with a soft cloth. They penetrate granite house, but would not leave any film on the surface or coating. What does this mean? This shows that the stone has been protected within the surface does not. Osmotic protective agent is sufficient for granite, calcareous stones such as agate but, marble, travertine, limestone, etc. are inadequate. These natural stone may be dimmed, but the acid corrosion of the surface even.
How to use the oil granite Protectant
Slate. Seal the table into several parts, each about 4-5 square feet, so that more uniform seal.
Limestone. With a rag lightly coated with the oil-repellant to the granite countertop. You can also use a soft brush.
Sandstone. Put it aside for 3-4 minutes until the protective agent is absorbed.
Travertine. When the protector is almost dry and do it again. The amount of protective agent to be less than the first time, with a clean soft cloth coated evenly.
Mosaic. Repeat the above steps until the entire table completed.
After 6.2 hours from the beginning these steps. Protectant penetration depends on its brand. Some protective agent soon, but some slower. Best to read the next instruction manual.
Note
Oily protective agent can be well protected granite countertops, but only this is not enough, if you want to keep bright as new granite countertops to the need for regular cleaning. Prepare some stone soap (natural plant soap also). Stone in the regular deep cleaning soap to form a thin film. They help prevent dirt, debris, pollution, granite countertops, they function the same with the washing liquid, but more moderate, more secure.

The company engineering and technical personnel, affirmatory finally discussed as follows scheme.
L, protective agent choice and process
A. li diligent 206 oily all BS a protective agent type marble fluorine. BS a 206 solvent containing fluorine marble protective agent is the new generation of high-tech and comprehensive marble nurse agent, with super permeation, can penetrate into marble facing 4 ~ lOmm, form a firm, durable crystal layer, effectively increase the burnish, but not marble marble color, can change completely locked dust, water pollution, such as water, coffee, coke, soy sauce, tea and other pollution, especially on the marble for pollution, machine smeary wait for the oily substance have excellent protective effect, effectively prevent marble water spots BaiHua, vomit yellow nonstick, pollution of various diseases, life appear. The antifouling agent keep the permeability of the marble, its super chemical resistance, anti ultraviolet ray and weatherability can reach the lO ~ l5 years. Main products are completely environmental protection, active components is American FDA (U.S. food and drug administration) approbate substances. Therefore, the products in contact sclerosis of food, no toxicity, not to be harmful to humans.
B. li diligent BS a 202 oily marble protective agent. BS based on modification of a 202 of organo-siloxane intermediates, can effectively infiltration marble capillary channels. Through the moisture vapor catalytic effect, and marble material is fully combine to form a deep and lasting protective layer, marble material surface leave no traces, and maintain the permeability, marble, even the marble surface parts wear still has good protection internal performance. Effectively prevent marble water spots BaiHua, vomit yellow nonstick, such as the emergence of various diseases, the antifouling agent has good anti-aging sex, long service life.
C. li diligent BS a protective agent 218 underside marble. BS a with the acrylic resin 218 based in marble material surface, can form a layer burnish, tenacity, transparent protection membrane, and granite deepen surface colour, provide extremely high gloss, strengthen internal structure, can prevent completely water, oil, especially water pollution, such as water, coffee, coke, soy sauce on the marble, tea and other penetration and have all-weathe sex and not yellow. Used in wet installation underside processing, can effectively restrain marble water spots BaiHua, vomit yellow nonstick, various diseases, pitting appeared, alkaline is admirable.
D. li diligent Bs - lo0 coupling agent for modification a 100 Bs special bingxisuan rubber latex, and Bs are 218 and cement a good rapping.
Correct use of BS a 100 can do after wet marble protection not empty esther the drum.
2, construction preparation
A. will need to conserve marble clean;
B. marble fully dry;
Three, organization construction
A. use li diligent BS a whole fluorine type marble 206 oily agent of marble material surface protective shielding processing, use clean wool brush to brush again, transverse in longitudinal brush again. Health after two hours of reentry procedure.
B. use permeability excellent li diligent BS a 202 oily marble protection agent in and around the underside of marble material to make a protection.
C. for a full penetration to 202 BS marble, the marble material surface without wet within 1 hour mark (the shortest), to use li diligent BS a marble seal protective agent 218 do it again protection.
D. after the above two times protection, marble material will have excellent waterproof, prevent alkaline can, spread 2 thes won't produce water spots, BaiHua wait for disease.
E. marble, and larger specifications due by twice protection after the marble underside strong hydrophobic, at that time if conventional cement pastes, will easy to cause the wet marble empty drum.

Marble floors and repair the damage
Production of natural marble that more and more widely used by people in the building, partly because of its architectural features with the other, the United States because of its decorative effect. Now we are in some large hotels and other buildings can be seen in which the application of marble, but also for its stately, elegant and magnificent decorative effects are impressive beauty. However, due to the natural characteristics of marble, but also determines the marble in its use will produce a variety of problems, or even result in damage to this material respects with the marble itself, on the Limestone, with the installation and use of the environment.
We are often in some large hotels and other public places to see the marble laid on the ground with a partial or a large area of damage, like cracks, broken, powder, holes and other phenomena. In particular, these phenomena with a marble floor in the most common. As these parts and easily damaged and difficult to remove contamination, people will see is full of dirt riddled the ground, which with its surrounding environment and reverse the formation of elegant great contrast, greatly reducing the use of marble value and effectiveness. But people can not easily and simple to replace the damaged marble, materials and labor on the one hand will cause the loss of large areas, stone the other hand is also very difficult to sustain the owners replace the marble and bring closure related losses. Therefore, the discussion and use of some effective methods and materials for damaged marble to repair the ground it is very important.
First, the causes of damage marble ground
1, the ground-based part of the settlement and the tear resulted in surface cracking of marble.
2, the external surface of marble damage caused the damage.
3, selected from the marble marble floor holding motivated to leave the troubles. On the one hand because people often choose to focus only on the marble color, and not to think marble and granite in durability and wear resistance differences. On the other hand, initially mostly imported marble to marble, granite processing technology was not advanced now, and marble colors and styles to elegant multi-majority, which makes indoor marble now become a fashionable choice of marble, which marble marble floor is now a major cause of many problems.
4, marble natural defects. Some of the natural marble, there are more defects, such as cracks, blisters, loose, half-cooked and so on. These deficiencies without first good repair and make up, then once to the ground by laying a number of harmful pollution, humidity and it will take the lead after the defective parts in the occurrence of disease and destruction and thus extending. Like silver beige, Golden beige, brown net.
5, humid environment. Marble's main ingredient is calcium carbonate, which will expand under the action of water, then the marble structure will be more relaxed parts of the first burst open, leaving the marble floor is a pit. The craters formed in a wet environment will Slate to powder, loose qualitative change in the surrounding rock.
6, the error protection method. To land owners and construction on the part of those terms, even though they painted on the marble in the pre-repellant, but the shop to the ground or there is a problem. This is because the cracks and loose parts of the marble has not been good repair, wet marble on the back of a greater water pressure as soon be destroyed. On the other hand, although the front has done a marble protection, but also on the ground water along the marble into the marble cracks and loose parts inside the marble and humidity increase, thus forming a vicious cycle.
7, the wear and tear damage the marble surface gloss. The lower the hardness of marble, strength is poor, therefore, marble floor, especially the location of acts will soon lose more luster. Such as walking Lang, lobby, counter and so on.
Second, measures to prevent damage to the marble floor
Damage to the marble floor of the above reasons of analysis, we can see that in addition to as much as possible not to select a loose material in the face of marble, the water is a major cause damage to the marble.

Artificial white marble and white marble of the difference between simulation
Artificial white marble is a natural white granite as the basic raw materials (accounting for more than 90% finished), the use of polymers (mainly resin) and the corresponding defoamers, UV absorbers and other materials, preparation of chemical slurry, injected curing mold made of a composite material, to a certain extent can also be thought of as a synthetic marble products.
May be different because of the mold sheet made of a variety of shapes, rails, Roman column, pillars, lions and other styling products.
Artificial white marble plaster mold is to use 1:1 or timber made of the shape of the finished product, and then Limestone, or polyvinyl chloride material made of fiberglass turn die, will the prepared slurry into the die, the vibration, pumping vacuum, maintenance, stripping can be.
Simulation of river sand is white marble, marble, talc, cement, reinforcement bars inside, but also with the shape of the required pre-cast mold, then cover with white paint or marble paint, lacquer can be. The basic material is a result of man-made white marble marble, and great strength of the resin used, so in addition to basic physical and chemical properties of the marble rather, some properties also higher than the marble, such as bending strength: 19.0MPa> 7.0MPa (standard indicators) ; compressive strength: 52.6MPa> 20.0MPa (standard indicators); radioactivity within the exposure index <1.0, the use of unrestricted; radioactive external exposure index <1.3, the use of unrestricted; by 600h artificial aging is still superior products, and the color does not change.
The use of river sand and some raw materials to do the simulation enhanced by the use of white marble is just cement and bonding material 20% of the total binder resin of high strength is not used.
Using the Slate two methods can also produce sandmarble, reconstituted marble, art marble, artificial marble works of art, landscape marble, sculpture, murals, etc. The basic principle is the same.

Loose marble on-site repair and refurbishment
Currently, the use of marble and granite building materials a lot of ground decoration, some marble, loose material, porosity and high water absorption, particularly in their daily walk around the ground wear, natural weathering and marble disease such circumstances, will result in raising board, explosion grain and other damage.
General construction in the past, most have not been on the conservation treatment of marble, so soon after completion of various diseases occur, such as yellowing, efflorescence and so on.
A few years ago, a company in Shanghai, to undertake a 28-story commercial building on the ground except yellow, repair, refurbishment. The marble building had contracted suppliers have asked us to deal with the ground. Check their site is: This building is almost entirely silver ground wire beige, board large pan base, a gray. Touch, feel granular substances.
More than a year later, the building engineering department of corporate governance through advertising that marble disease, called and asked for treatment. To the scene they were surprised, only a year left and right, the original pan base has become a large area where yellow spot, the place has shown a serious brown. Explosive particle board, resulting in pits, large pieces such as nails, a small grain of rice, everywhere.
At that time the construction sequence is: In addition to dealing with a polished one of macular hole repair a water conservation. Proved defective in that order. As the process is not correct, in each construction of a number of problems have occurred.
1, in addition to macular treatment: they collected on the market of imported and domestic, and self-made syrup for several samples. marble confirmed the injury and can not place a pharmaceutical macula, followed by a large area of construction, the cleaning can remove 97% of the macula. 3% still had no effect after repeated brushing. Can only seek the consent of the owners to take sample for laboratory analysis, preparation of targeted agents to be removed. Occurs because the disease can not be a cause, so in a different formation mechanism of pharmaceutical-related macular generated is impossible to process.
2, grinding and polishing: polishing said under normal circumstances should be no problem. However, due to the plate through the corrosion, loose surface, the grinding process. One side polished. Board side of the explosive particles. The old holes were polished, and the new holes have appeared.
3, hole repair: repair holes take longer, be patient. We used hot glue repair, not ideal, strength is not enough. Easy to fall off, when the soles of shoes through the dirt will stick to the glue on the formation of black spots. Fill with marble adhesive is not satisfactory, as after the first fill plastic polish, marble polishing plastic heat generated in the case of feeble fall: especially holes, if the first polished glue. Then can not afford to make the glue marks, and glue at the dull, resulting in scarring.
4, water conservation: selection of water-soluble surface protectants, may be more operative than brushing, poor ventilation, not even after eight hours of drying, place the next day found a black sheet lined deepened, in some places become green. By observing the reasons are: water-soluble curing agent contains water, water in the gap if they can not quickly evaporate in contact with air oxidation to generate a new disease.
The main reason for this failure: the board by corrosion, has become loose. So be on the plate reinforcement. Reinforcement material in the company discovered that some tests can be, but not ideal in the field test results. Analysis found that easy to deal with the company to do sheet and dry in the field even if the local heating drying board until the heat left, bottom and sides of the moisture will come in soon invaded, occupied the pores, so that reinforcement can not penetrate into the marble interior. This will, as a polishing agent reinforcement, like peeling the skin tear down, would not achieve the role of reinforcement. Construction at the site of a large area plates can be dried, so in the choice of reinforcing materials, must be selected hydrophilic, strong penetration, good polishing, strong bonding, without causing discoloration of marble materials.
Based on the above revised construction sequence:
1, with 50 mesh coarse Slate, first floor flat polished, the marble surface of the pores open;
2, air dried in the air: as the ambient temperature. Ventilation at least 24 hours or more;
3, infiltration of brushing solvent curing agent, water and hazardous substances blocking the bottom up, dry it after brushing;
4, dilute the concentration of brushing reinforcement point of the first pass, let it penetrate into the gap. L2-hour coverage of plastic film to prevent solvent evaporation. Thicker coating was the second time, you can repair ~ b4, tL holes and small cracks, still covered with plastic film for 12 hours;
5, patch holes: The strong bonding, polishing and good glue, with lust, first fill a large hole to fix a small hole, fed slightly higher than the board. Dry it thoroughly;
6, 300 butterfly with a 100 # piece rubbed off a gel scar;
7, with a 3ooo # ~ 500 # grinding;
8, polishing:
9, crystal face, or waxing to do maintenance;
By the order of construction, the grinding plate is not critical in the grain, polished smooth as a mirror. Through a period of observation, macular no longer generated.
