All kinds of curtain wall advantages and error fallacy

One, the advantages of stone curtain wall and error fallacy

Strengths:

1, natural material, light crystal, strong forever, and honour elegance.

2, resistance to cold sex: stone in damp conditions, can resist freeze-thaw and not occur, the destroyer of burnishing the obvious function called sexual. Freezing resistance The water in pores of the rock in low temperature to 20 centigrade within freezing happens, the pore water expansion than original big volume 1/10, rock if not resist this expansion force of what happened, it will appear damage phenomenon. A buddhi bibulous rate less than zero. 5%, will not consider its anti-freeze function.

3 compressive strength: the compressive strength of stone material from mineral composition, crystallization, cementing material granules of uniformity and load area, load made with detention cleavage Angle of identity, and somewhat different. If other conditions, common crystal particles as small and the density of the binder each other all the material, it has higher intensity. The volcanic rocks in the dry density and saturated water, Limestone strength and no difference (bibulous rate is extremely low), in the case of porous and afraid of water, the cementing rock strength of the dry and wet, there are bright markedly different.

Error fallacy:

1, cumbersome stone do high-rise buildings' walls in many serious danger the bidding of construction is not completely standard, many stone curtain wall project is the cost of the lowest who who, individual subcontractor of, so low quoted price in order not to lose money, to cut corners. Senior (50 to 100 meters high) with stone curtain wall 100 to 200 yuan a square meters of low class, not exactly a lot of granite dangerous?

2, a lot of curtain wall design on the drawing not familiar, draw range, what can be marked curtain. Stone curtain wall is not exceptional also, by the companies themselves the curtain wall design, some design institute please layout teacher carefully review, but most of the design institute ZouXingShi review of the design can shut this dangerous?

3, each building engineering, countries are required to have supervision company responsible for quality, it is entirely correct and needs is ensuring the quality of projects is important, but unfortunately supervision engineer many is civil engineer, don't understand wall, let alone stone curtain wall. This is due to the lack of training materials in supervision the curtain wall materials, a lot of supervision is retired staff to carry trade, without training don't understand how the supervision, the curtain of good last quality? Sandstone, because all of the building new craft learning in quality, less when acceptance of often encounters also harder.

4, stone curtain wall fire prevention function is very poor, especially in high-rise buildings, fire is normally in indoor rekindled, inside the building fire will make hang SLATE of stainless steel plate and the metal layout temperature, make the steel bate, off and intensity, SLATE will from the senior constitute a SLATE "rain" falling, and not only to cause dangerous, also gave pedestrians caused by fire fire fighting hard. This as the United States by the WTC, because the wto as defeating fall is filled with steel layout, steel temperature drop to soften the intensity, the twin towers collapsed constitutes a top-down fall.

Second, glass curtain wall advantages and error fallacy

Strengths:

Glass curtain wall is a kind of new wall of modern architecture, it is the biggest characteristic of beneficiary will architectural aesthetics, architectural functions, such as building energy efficiency and architectural layout organically the same way as the same Angle, building never show a different tone, with the sun, moon, lighting change give a person with dynamic beauty. Alive bound all continents major cities were built with grand beautiful glass curtain wall construction, such as the New York world trade, between Chicago oil mansion, sears tower took a glass curtain wall. Hong Kong bank of China building, Beijing Great Wall restaurants and Shanghai fellowship building also soon take. Error fallacy:

Glass curtain wall also has some limitations, such as light pollution, such as large energy consumption in question.

Other, glass walls bright and clean and transparent generating beauty don't really resistant to pollution, especially in the atmosphere HanChenLiang more, air pollution, the lack of rain of northern regions, glass curtain wall easily to cheat dirt accept dirty, the urban landscape is concerned, not only can increase "light" lost "face", instead. Qualitative terrible, construction quality used is not high, appear luster, ripple severally uneven, because light reflecting not controlling, led light environment of chaos. But these questions with the new material, new craft is present continuously, gradually into architectural modeling, construction materials, the comprehensive research of energy-saving building as a whole system, the design of the question to discuss deep.

Three, metal wall advantages and error fallacy

Strengths:

The leading products metal wall? Aluminum curtain? To date, the metal walls today have been in aluminium &granite curtain walls dominate metal wall, lightweight material, cut the building load for high-rise building supply the excellent choice condition; Waterproof, anti-fouling, corrosion resistant function fine, to ensure the building outside surface hold long new; Processing, transport, installation, etc are compared for its implementation, and easily generally use supply strong handle; Colorific diversity and can mix processed into different appearance shape, expand the architect's design space; Higher than the function of price, and easy protection by long life and anastomosis owner's request. So, aluminum curtain wall as an extremely wallop form of construction, extremely popular.

Error fallacy:

1 and curtain wall system resistance to deformation of curtain wall system ability: must every major parts of the mechanical calculation, consider scientific air pressure, weight, temperature, etc to set, the influence of curtain wall system reform, and built-in, running through the connection system, keel system, panel and fasteners for careful checking, ensure the safety of curtain wall.

2, plate isn't take floating through connection; Float type throughout the connection guarantee the curtain wall deformation recovery capacity, ensure the integrity of the curtain, doesn't make the curtain wall by influence caused by deformation, avoid force of curtain wall surface drum convex or sag scene happen.

3, plate fixation compiled for the fixed plate tectonic plates installed flatness compiled plays a decisive influence. Plate force inconsistent each protection can cause surface sheets deformation of decorated the fixed effect, so plate must be taken from compiling the fixed tightly shall prepare the flatness, ensure curtain wall surface

High quality stone material choose and buy law

For processing good product facing stone material, its quality stand or fall can from the following four aspects to identify:

A view, namely macroscopic observation of stone material surface structure. Generally speaking, uniform fine material structure of the stone has exquisite qualitative feeling, for shi caizhi beautiful is tasted; Thick bead and differ the stone material of grain structure its exterior effect is poorer. In addition, the effect of stone because geology in which produce some subtle often most easily crack, stone material along in these areas, we should pay attention to eliminate rupture. As for lack of edges affect beautiful, when the choice is especially should note.

Second volume, that amount of stone material specification, lest affect joining together, or cause after mosaics pattern, pattern, line deformation, effect decorates the effect.

3 listen, namely, listen to the stone material percussion. Generally speaking, good quality stone its chiming ringing and euphonic; Conversely, if the stone exist because of weathering cause mild fissure or particle become loose, criterion knock voice is husky dumb.

Four try, which USES a simple test methods to test the stone material of good quality. Usually on the rear drop in stone small-scale ink, such as ink soon infiltration out four sanctions, namely that stone internal particles loose or existence aperture, stone material quality is bad; Conversely, if ink drips to be not moved in place, then explaining stone texture is good.

Some Suggestions:

1, stone radioactive certificate, please you are buying for to distributor. No card don't buy, simultaneously must note, domestic outfit to choose, is A kind of product.

2, in the marble and granite choice, should first consider marble, granite, under normal circumstances, the radioactive than marble radioactive.

3, normally, stone material consideration should be black, gray, meat, red, green, red, from radioactive perspective, from high to low, is as follows: the red > > > meat red green > > white gray, is basically this sort of black.

How to identify the appearance quality from the marble

As a kind of high-grade marble decorate stone, when the choose and buy must discreet, identify marble exterior quality from the following several items from his hand:

(1) the judge in a good light tonal pattern, will have elected under the condition of good plank and other want a choose and buy with the marble and flat on the ground, stood in the distance they 1.5 m place careful visual. Requirements and batch of marble decorative pattern is tonal should basic harmonic.

(2) check surface defect in a well-lit conditions, will plank uncrossed on the ground, standing at a distance of marble Lin place observation invisible defect think no defect; Standing in Lin place can be seen from the plank in 1. Library functions like sin place not obvious flaws; for no obvious flaw Standing in the distance plank 1. Obviously the defects of library functions like sin place that flawed saw. 'specific observations of defects have I plate wrpping; Plank surface crack, sand holes, or different spots, stains and cave phenomenon exists. If convicted the above several defects not for classy article, also is plank not lack edges are positive plank drop horn defect; If above defects not obvious also no obvious lack of edges, so can drop horn that this plank as primary product; If there is that several defects but do not affect again use, and plank positive only 1 8mm, director not greater than 3mm wide not greater than lack edges or length and width are no greater than 3mm drops horn, may judge the plate for qualified products. Plank in the transportation, loading and unloading process and touch bad, can undertake bond (against rupture plank) or repair (on the surface of angular defect, certainly some pits or hemp dot). But felt, repaired positive is not permitted, color to trace evidence with positive color close.

(3) to examine mark marble mark order: naming, classification, size, grade, standard marble named order: waste material origin place names, decorative pattern is tonal characteristics, code-named the name, marble (M). Marble is divided into two categories: plate type (doppler code-named N) : for a square or long quadrate plate; Alien sheet (S) : code-named for other shapes of the plank. There are three levels: marble plate sessions (code for A), grade A (code for B) and qualification (code for C). Hierarchies basis is the size of allowing partial plate flatness allow limit bad, tolerance, Angle allow limit tolerance, exterior quality and mirror light ze degrees. For instance with Beijing fang shan magmatic white marble of waste material production at 600mmX 400mmX type size of the product for 20mm sheet named: fang shan magmatic white marble big lidan, marked: fang shan magmatic white marble (M) N 600X400X20BJC79 marble in the factory should clearly indicate: the factory, the trademark, mark production. So by checking markers that the overall appearance of plate quality understand somewhat.

How to let granite color becomes red

Color liquid preparation methods and process:

< 1 > water dissolved ferric chloride and made color liquid adding a few catalyst.
< 2 > the granite into and immerse completely in color liquid.
< 3 > soaked after certain hours after cleaning, drying out colour-display namely get red granite.

Production process matters needing attention in:

< 1 > color liquid concentration: different concentrations to obtain the different color effect, production should see actual situation and stone, general concentration of 20% for the best.
< 2 > immersion time: should have sufficient time, time is too short shader is bad, but time is too long, work efficiency is not high. Generally take 3-4 hours as well.
< 3 > color liquid PH value: PH value too and too small to the granite color variation is bad, generally take 2 for the best.
< 4 > drying temperature: general selection in 200 -- 250 ℃ (Celsius) advisable.
< 5 > drying time: take 2 hours.

Solid stone and granite comparison

ShiMian material seam solid manmade smooth and inconspicuous, so there won't be ugly and shelter evil people and practices of the engagement gap. Brunet granite juncture is almost invisible, but in light of granite workbench face, juncture is obvious, and similar cases were also found in joint tile cement flat-fell seam.

Heart man-made stone material can cut into independent shape and radian, complex edge shape, tailor-made mesa sink and heat insulation frame.

All sorts of color of solid man-made stone can also easily with other material Mosaic or each other, killing excellent mesa effect. Solid man-made stone with a variety of colors and textures, including several shades of different natural color and light color series, suitable for today's general kitchen clean well-ventilated style, and color, design and color is consistent and unified.

Granite design without man-made stone so volatile, edge shapes have limits, and enchase other materials it would increase ugly juncture.

Granite main show dark heavy colors, light color few other options. Granite tonal and texture often change, the color may and selected sample different.

Solid stone plate can be used below the basin sink seamless method and combining smooth, have no seam appearance, nor plate edge concave a hiding dirt. Meanwhile, the arc from retaining water design, after the seams to clean. Granite working mesa can also use below the basin sink, but splicing method of installation will leave space, easy to harbor moisture and dirt; And granite general will not have arc retaining water after the design, because at least need a apparent juncture.

Solid oil intense and obvious translucent feeling, touch up smooth comfortable, like leather and wood, emit warm inviting feeling. Granite is also very smooth, but touch up a little bit cold and hard, glassy.

Cleaning and maintenance.

Man-made stone clean easy, just use soap water or a household cleanser will clean up; Its without holes, make the material of water can't permeate, not be treasured besmirch, also won't mildew and bacteria. Because of solid stone clean sanitation, so the hospital operating room ready to use, and the national sanitation foundation listed in the list.

Granite need often maintenance, because this kind of material porous, need coated non-permanent surface sealants, just produce stain. Granite is more difficult, to make the surface cleaning the small cracks and grooved kept mildew and bacteria not is not easy. Most of the soap or household cleanser is not to be used to clean granite, because can produce besmirch, must buy chemicals from the granite supplier cleaning carefully. Scale if left on the surface, it's very hard for the granite, sometimes much more clear and will cause wear cost money please specialist burnish.

durability

Mosaic man-made stone is a kind of advanced composite, by natural minerals and pigment made of methyl methacrylate slime mix, it is difficult to cause permanent wear. Because of its color and pattern throughout the entire block material thickness, therefore can be completely refurbished. Concave grain, gap or scratches can use ordinary household cleanser, 100 clean cloth or young polish paper easily eliminated. To prevent thermal penetration loss by solid stone, can be in mesa inserted into heat insulation frame or ceramic tile, forming a placed hot dish device safe place.

Granite is generally regarded durable, but in granite cracks, natural aperture and impurities can cause unstable part, and these sections will sometimes make granite table cracked. Granite generally not easily by scratch, but once appear sunken grain, gap and scratches, are very hard to remove. In addition the average consumer will have under the delusion that can directly on the hot container on granite. Actually it is not recommended because thermal protection will destroy the surface, make the granite easy lane unclean.

Solid man-made stone and granite comparative glance (for kitchen workbench). Below is stylist and consumer choice kitchen work mesa material in the main characteristics and advantages on comparison, results in 18 proposed characteristics and advantages, solid stone 16 points in equal or higher granite.

In the image is superior, resell remained high value two, two kinds of materials are higher evaluation. In unified level quality, good installation maintenance support, integrated kitchen sink (no sleazy plate edge concave edges), smooth solid obviously juncture, why don't handle change boundless, easy edge after repair, can add arc retaining water design (no filling embedded seam), colored enchase decoration, antifouling performance (talented whole), various monochromatic selection, but tailor-made integration mesa sink on the spot can be modified easily and, bending and overall design of heating high elasticity this 14 items, solid stone score significantly higher than granite. In heat prevention ability, prevent scratch ability of two items, granite score higher than solid stone.

How to choose decorate stone

Now, more and more household is decorated in stone, but most will use decorate stone, owners don't understand fundamental no alternative.

Therefore, the author summarizes the adornment, select material experience for many years, let owner performance of know all kinds of stone material quality:

Marble: ingredients are calcium carbonate, mo type hardness is only 3 to 5 or so, and generally hard device in the sun after, Sandstone scratches light 2 years, and tiny have surface is easily absorb pollution, not easy cleaning, and often accompanied by radiation, a health hazard. & NBSP;

Resin yakeli man-made stone: the production process is a natural limestone join 2% - 80% of chemical resin or acrylic ranging, via 200 degrees Celsius, the advantage is pressurized forming heat without radioactivity, light weight, easy installation; Defect is hardness, afraid of Nick, fear not insolate, easy fade, and not high temperature resistant, 400 degrees Celsius will scorched, smoke, there are burning smell. & NBSP;

Jade: USES pure natural raw material, material of adverse substances in removing, analog natural jade ecological environment, Cui refined by 1300 degrees Celsius and into. Faults: strong hardness, difficult processing; Advantages: crystal connect fully, green granite material, no radiation, not afraid scratching, durable, easy to clean, new, resistant to stay healthy, not insolate, wen run smooth ageing.

Install stone fence six steps

stone fence has been applied very early, to protect animals and poultry to prevent accidental damage. Stone fence installation steps can simply summarized by the following six:

1, calculation of stone fence length and required height. Holding a GPS (global positioning system) new fence along the line go again. This will effectively measurement and draw distance.
2, within budget find suitable stone. Most of the stone fence built are using local usable stone. granite and limestone in stone material construction of the fence is the most common types.
3, will stone cutting into the rough rectangular shape. Stone size can change compared to increase the fence. These stones can usually from local quarry or stone suppliers. Early cut
4 in the need to install the stone fence, dig a trench, the place with loose gravel filling, will chunks of flat stone installation in sand, lay the solid foundation.
5, between fence left some spacing to flow away.
6, continue to install stone align, much circle of a solid stone crisscross pattern joints. If not installed dry stone fences, between the stones can be used mortar. Laying stone, until desired height.

BaLinShi, stone introduction

BaLinShi membership pyrophyllites, rocky, channeling clear, renew the fine texture, the brilliance is bright, clean, resembles baby tender color charm of skin, delicate and clinking. Sandstone "prairie in stone, the reputation of treasure, this stone crisp refreshing warm, soft hard moderate, adaptable, is engraved in stone fine quality goods, be opposite is over, can't help produce sizes of rich fancy, exclamation of creation nature magic. Some called bahrain acura stone is the collection "shou TianHuang" honor, ChangHua stone "dissolve" colourful, accumulate "FengMen green" qingtian, seal the altar, its evaluation are spectacle for the BaLinShi portraiture.

Main ingredients:

According to geologists introduction, BaLinShi contain silica and alumina elements of the flow lines rock, is volcanic hydrothermal altered role of the formation and happen kaolinite. In the late BaLinShi metallogenic sulphide and other minerals some along fractures through, or combined, dyeing cloth, and patches of expanded kaolinite number of varieties. In addition, in addition to silicon and aluminum, calcium, magnesium, sulfur, potassium, sodium, manganese and iron, titanium elements of existence and percentage changes, also made BaLinShi rich color. Like iron element more will make stone was yellow, red, manganese, appear the invasion of the stone has the phenomenon, aluminum plants spend more, stone elements can appear gray and white.

Varieties division:

BaLinShi points f Yellowstone, stone, colorful, frozen stone four categories. A scarlet, orange, yellow, purple, white, grey, black; Have not transparent, micro transparent. BaLinShi is massive. Exquisite and lubricant, glittering and translucent, is rare imperial stone material. Bahrain stone carvings are best at shaping bird feather, horse-hair, cattle hoof, sunlu, lawns, petals, etc, is a carved stone one problem. Bahrain stone carving out by the chicken connoisseurs, seals the curiosa of seal is called.

Morphological characteristics:

Bahrain stone is exquisite, wen run is downy, transparency, hardness is taller than shoushan stone, QingTianShi, ChangHuaShi soft, unsuited stamp-carving or elaborately carved handicraft, for purpose of stone, slightly not enough is not stable, such as pigment ingredients easily stone, bahrain stone oxidation, fade, especially in sunlight and ultraviolet irradiation, mercury, after half an year, easily decomposition average 60% of stone have different degrees of fading. Again scrutinize both texture, BaLinShi ChangHua is purely decorative pattern, more. So there is a peer praised both "south" (BaLinShi blood north to child good), each has his strong point.

It is the collection of the treasures. Several times in domestic exhibition, reputation full civil things, from Hong Kong and Macao regions, to southeast Asia, Europe and America to dong ying, almost from the whole world, or dragon. BaLinShi international market in exports, have been since covered the focus of world attention. In the United States in 1979 and crafts exhibition held in China, with seven pieces BaLinShi exhibits, very exciting and popular. As BaLinShi mini-sculpture, connotation is rich, it not only covers the ancient civilization of chifeng district has revealed the hongshan culture, grasslands bronze culture, liao culture and Mongolian yuan qidan profundity, and will culture with elegant mini-sculpture, in the history of human civilization write a heavy amal. The classification of BaLinShi named, basically adopts the traditional name, but the seal stone also have their own name copies. BaLinShi substantially can be divided into stone, f Yellowstone, frozen stone, colored stone.

Bahrain f Yellowstone

TianHuangShi regardless of the same caliber, with shou called "sisters stone", its rocky to transparent and downy, without brittle, colour and lustre Kennedy yellow immaculate, integrating fine, clean, embellish, greasy, temperature, coagulation six factors at a suit, rare, precious JinShiJie extremely, known as "one inch f yellow inch gold," said

Bahrain stone

Is BaLinShi in the acura, always have "world stone in China, China stone in bahrain" view. The stone, the stone to warm blood stains on solid gather have send, red light person, like icing on moon month wainscots. Newly mining chunk stone, its colour comparative and intense, but person, particularly following dazzing. Its size for domestic biggest, dubbed "the Chinese stone king".

The natural stone with design

Natural stone material can make a yard or a park in more colorful, can be found in a variety of forms around the stone material of natural landscape, such as a sign or wall. You can will stone into your own yard public landscape to enhance its diversity.

Streams and waterfalls

Rock let streams and waterfalls looks more natural. When pouring in the riverbed waterfall, can produce different landscape, forming the rapids, effervescent streams, or the landing point waterfall. Scattered around the natural stone material can be surrounded into a meandering flow.

Stone walls

Stone walls can create classic old appearance, also guaranteed enough privacy. Ivy or in natural stone fence lichen growing. If plus a little extra effort, you besides can have a charming stone walls can also have a elegant gardens.

Terraces and sidewalks

Irregular shape stone can be used to laying terraces and sidewalks, color can from red to grey Slate. Gazebo scaffolding, wall can partially border, or shrubs, give a person comfortable feeling, and sidewalks can laid into case shape structure or keep boundless. Winding stairway, create more charming than straight road of appearance. Pebble alleys path slightly formal than stepping stone.

garden

Natural stone material can be in strengthening the gardens of the natural glory. Can use natural stone material as Taiwan edge. Mixed use stones, stones and rock plants, creating a rock garden. Stone can big garden notable features.

steps

In the mountains and slope can use to create a beautiful stone steps. Steps can according to your idea or wider or narrower, as long as they are large enough to hold people's feet. In formal gardens, a large-scale central stair can lead to a lower position in the wild, and garden, stone steps to perform the same function.

Limestone quarry industrial cause of environmental problems

Mineral rock has become the thousands of years of human infrastructure since an important resources. Modern industrial scale faces many problems, such as limestone quarrying industries to the environment enormous pressure.

wastewater

Almost all of the stone mining quarrying industrial process can produce a lot of wastewater, Limestone quarry industry is no exception. Water use is very wide, such as using high pressure jet and lubrication solid cutting tool. Wastewater can have limit recycling, but will eventually become sewage. Pollutants including machinery in use process in the natural material such as oil and gas, still pack of excessive natural deposits.

Material precipitation

Waste discharge high entrainment concentration. The flow downstream sediment start filling, aquatic species have begun calcified environment. Calcium carbonate is limestone, one of the most important minerals formed from an animal found that many of the absorber and double shell, especially of mollusks. Too much calcium carbonate might be dangerous.

Grund water levels fall

Limestone need in the water dissolved minerals, which means many limestone quarry out to flush must have water sediments. Excessive pumping will reduce the ground water level. If a coal mine near the coast range, groundwater after dry inland saltwater intrusion would lead to. The natural hot spring by groundwater supply due to reduce the pressure would dry up, but also may lead to the destruction of ecological system of water resources, and even human shortage.

Noise and air pollution

Travertine quarry industrial two atmospheric environmental impact is mining machinery noise and high air of dust. According to the wind and the surrounding vegetation, air in the dust can with the wind from migrating to the mining area, affect dozens of miles of the residents of health, especially for those who have been the inhabitants of lung problems particularly disadvantage. Using heavy machine generated quarry the noise pollution of the local wildlife will scare away.

Artificial sandstone of two kinds of installation method

1) dry-hanging method

(1) draw lines on the wall.

(2) the wall there is embedment parts can be welding Angle yards, main keel, times keel, with metal Limestone installation; Don't have embedment parts can use chemical anchor install the keel, then install times keel, use metal guajian install artificial Sandstone.

(3) using sealed last crack.

2) direct installation method

(installation height is usually low "2m) and stickup law

(1), with white adhesive gear-shape offset spatula in man-made sandstone with good glue the back in put on the metope stickup line rocks. Artificial sand

(2) the next supreme installation, from after drying, beautification aperture.

(1) the characteristics: artificial sandstone sound insulation, moisture absorption, resist breakage, outdoor not weathering, water not melt, and not long lichen, easy cleaning, etc.

(2) the advantages: artificial sandstone moistureproof, prevent slippery, sound-absorbing, absorb light, tasteless, no radiation, do not fade, warm, sweet elegance; Compared with wood, no crack, deformation, decay, do not fade. Product installation simplification with rose, as long as can stone carvings fixed in the wall, the product can decorate with wood to make the connection, background modelling organic play a perfect the space, overcome traditional installation trival and reduce stone installation costs. Decorated the house need not add other processes and paint can direct carvings installation wall.

(3) material qualitative respect: artificial sandstone is a kind of warm color attune adornment material, granite but elegant and sweet, coordination and do not break showily; The quality of a material, wood with stone texture, and spectacular landscape picture, color is rich, the closeness to nature, simple and elegant, in numerous stone was in "beauty premeditates" li stone ".

Simple stain removal marble table vinegar

If your marble table stained with the stain, there are better ways to remove the stain. Here are some simple methods, the marble table can save a lot of repair costs.

Step 1

Marble Desktop is very fragile. It is easy to dirt, everyone will happen. In fact, the stain is not just a stain, it can produce etched on the marble table. Vinegar is very susceptible to corrosion of marble.

Step 2

This means that there is no remover or marble polishing tool can remove stains, there is no need to spend granite. We can use fine gravel or sand ginger stains removed.

Step 3

Stain removal, the need to polish your marble back to its original color.

To do this, you will need to use the raw side of the leather. • Michelangelo Buonarroti is also used in ancient times, the method used for polishing the statue.

For the professional stone restoration staff this is a lot of trade secrets.

How to use the grindstone

Cooks in the kitchen usually has a variety of sharpening tools. Including Grinder, file and other sharpening gadget. Mosaic is to use an old grindstone.

Step 1

Right hand grip on the tool (if you are holding in the left hand for lefties), perpendicular to the ground side of the knife, the blade should be far away from you. This is the first using the grindstone sharpening preparations.

Step 2

The tip on the grindstone, one hand holding the tool with one hand and carefully with your fingers touch the face of your knife blade, the work is manual.

Step 3

For 20-degree angle to the blade edge against the stone. Sharp edge has been close to the grindstone, and the knife ridge is maintained at 20 degree angle.

Step 4

Friction on the blade of the granite, to maintain a uniform focus.

Step 5

From the tip of the blade with the continuing friction. Continued efforts throughout the process.
