SOLID SODIUM SILICATE
Appearance: Nearly transparent (slightly light blue), dry casting block, glass solid or wet water quenched into a granular solid.
It is widely used in casting, washing powder, transparent soap, paper making, printing and dyeing, acid-proof and alkali proof construction, plate paper bonding, refractory material, ceramic assistant, cement impermeable solidification and welding rod manufacturing and other industries.
Application
1. To improve the weathering resistance of materials, the density of 1.35g/cm water glass is used to impregnate or brush porous materials such as clay bricks, cement concrete, Portland concrete and stone, which can improve the compactness, strength, impermeability, frost resistance and water resistance of materials.
2. the reinforced soil alternately poured water glass and calcium chloride solution into the soil. The silicic acid gel formed in the wet environment absorbed the moisture in the soil and expanded the soil to consolidate the soil.
3. Preparation of quick-setting waterproofing agent.
4. Repairing cracks in brick walls by mixing sodium silicate, granulated blast furnace slag powder, sand and sodium fluosilicate in proper proportion, directly pressing into cracks in brick walls can play a role of bonding and reinforcing.
5. Sodium silicate aqueous solution can be used as the outer surface of fire door.
6. It can be used to make acid-resistant cement for lining of pits. Physicochemical properties
7. Preparation of silica gel
