Waterscape square marble conservation documentary

Shanghai Fl international circuit waterscape square marble the shop is stuck with an area of about 14000m 20000m, among them the ground, metope used 6000m, marble as shandong rongcheng grey porrino, its specification difference is very big, the biggest for: 12 x 600 x 20mm, small specification to many line, all the installation are wet marble for the post, it is undoubtedly a marble curing test. At first, the owner is intended to do low surface and stone protection, later in my company technical personnel's repeated advice and reasonable argument, the employer agreed to additional positive protection and caulking place protection.

Second, maintenance construction plan As is known to all, marble cement wet paste susceptible BaiHua, ShuiJian and we understand that in the whole Shanghai use cement wet stick marble almost no don't produce water spots. Shanghai Fl engineering and international key project, therefore, how to design a perfect protection scheme is very important. 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. When we have two options: one kind is the underside in done protective coating again again BS in a 100, a 100 not completely BS dry cement mortar when Isaac; The other program is in cement mortar mixing people in a 100, to enhance the BS cement and of marble material stick relay, finally, to do absolutely insurance, we and installation square consultations, two kinds of methods simultaneously.

F. marble wet paste caulking after completion, reuse BS handling of juncture place a 206 shielding processing.

Three, problems

Because of metope marble in wet posted in advance burrowing positioning, marble material surface in marble digging holes in the installation of workers (deep about 5mm) at the same time already will marble conservation layer to prevent serious damage, the grouting cement mortar infiltration, so when in position to ask before this section grouting practice all our workers to install protective agent and meanwhile besmear again a 100 to excavate coating BS in the hole, thus avoiding the reasons caused by construction waterproof maintenance has not arrived the drawbacks.

Four, the protective effect

The whole marble material engineering protection to install from 2004 to July 20, September 2, 2004, including waterscape square bottom end 1200mm 600mm x 20mm x marble from the earliest deployed about 6000m states.with 7,000 more hours, there is no place water spot phenomenon, get Shanghai Fl international circuit construction endorsed fully command.

epilogue

Everyone knows, marble material wet stick installation costs far less than dry hanging marble. But marble wet posted the biggest question is easy produce water spots, BaiHua etc. Various lesions. So, wet posted marble protection can do? Wet paste can not empty drum? We haili marble chemical Co., LTD. According to several years' exploration, grope for a certain experience, this has in some engineering
