Sodium methylsilicate is a new type of rigid building waterproof material with good permeability and crystallinity. The silicol group in the molecular structure is dehydrated and crosslinked with the silanol group in the silicate material, so that an “anti-capillary effect” is realized to form an excellent hydrophobic layer, and has the functions of microexpansion and increased compactness. This is the mechanism by which silicone waterproofing agents have a waterproof effect. Scope of use 1. Widely used in roofs, interior and exterior walls, floors, bathrooms, kitchens, basements and warehouses, and anti-seepage of reinforced concrete structures; 2. Used in underground civil defense projects: such as culverts, bridges, dykes, tunnels, large-scale hydropower stations, water diversion projects to reduce water erosion and prevent weathering; 3, used in various pools: such as swimming pools, purification pools, sewage pools, water towers etc.; 4. Used for high water absorption inorganic Aggregates: such as perlite slabs, roof tiles, cement bricks, high-rise building lightweight brick finishes, inorganic fabrics, insulation materials, etc., impregnation, so that it has a significant waterproof and moisture-proof effect; 5, used in water-soluble architectural coatings waterproof, color protection, pollution prevention, anti-aging, has been widely used in exterior wall finishing; 6, additives for latex paint, water glass, 107 glue, can make it It has obvious water gain, and can Maintain stable bonding strength; 7, used in petroleum drilling, can adjust mud viscosity and density, can effectively prevent drilling collapse, improve drilling rate; 8, used for later pumping of the oil well, injection into the oil production layer, prevent the crustal skeleton of the oil production layer from collapsing, so that the oil far from the well can be mined more smoothly; 9, used for other special purposes to reduce water absorption and seepage resistance
