In recent years, with the rapid development of architectural decoration industry and the rapid development of stone tools industry, the waterproof agent market is unprecedented prosperity, showing a trend of diversity and growth. Sol, spray, through coating, crimping, erosion and other methods, so that the stone surface evenly distributed and slowly infiltrated, forming a protective effect. The stone surface has the functions of waterproof, anti-making, oil resistance, acidity, alkalinity, gas resistance, furnace resistance, furnace resistance, anti-fouling melting, biological corrosion and so on, which improves the sealing life and decoration performance of stone.It is a new type of environmental waterproof agent: sandstone, exterior wall, shelter cloth, gypsum board, Portland cement board and so on can be used for waterproof coating and coating. this is different from silicic acid Natrium and Carrium. Single live ammunition and single alkane are the main materials. They're underwater. The surface prevents water and has no effect on the surface color. It is better than sodium methyl silicate and weaker than oily water repellent. They are. Between the two. The price is higher than methyl, but lower than oil. The mixed use of cement concrete can make the concrete waterproof as a whole. Because it is a water system, the steel bar in concrete is not corrosive and has a strong influence on the strength of the structure. For people's understanding, now more and more use. Yes. In fact, abroad, that is the mainstream.
