石材标准(国外英文资料) Stone protection Help Wikipedia refers to the name card stone protection spray, brush, roller, spray and immersion of stone coating on the surface of the stone, the stone in the pores of combine with hydroxyl reticular form a protective layer, thus prevent the phenomenon of stone disease. This kind of protective materials for main material (such as silicon silicate, siloxane) or fluorine resin material (such as fluorine acrylate), Portland with relatively low price, but waterproof, antifouling, UV resistance is less than the latter. Catalog classification Functions and differences of different types of stone protection products Implementation standards Stone protection construction technology The gap of different varieties of natural stone has the internal quantity and size of different pollutants, the stone surface or bottom can penetrate into the interior of the stone through the gap, the formation is difficult to remove water spots, stains, rust and Bai hua. The main material of stone protective materials for silicon (such as silicate, silicone etc.) or fluorine resin material (such as fluorine acrylate), Portland with relatively low price, but waterproof, antifouling, UV resistance is less than the latter. Siloxane has the best water repellency, but its antifouling properties are inferior to those of fluoro material. The most anti fouling type of fluorine, the best effect of water drops, but generally less waterproof than silicone. Therefore, there has been a grafting and compounding of fluorine and silane on the market, which can effectively integrate the advantages of silane and fluorine, so as to meet the comprehensive protection needs of the market. Edit this Section 2.1, according to the composition of the product dispersant types can be divided into water and solvent type. 2.2, according to the function can be divided into: Waterproof - to prevent water and water pollutants seep into the stone agent. Anti oil type - the basic function of water
