Widely used in metallurgy, electric power, petrochemical and building materials industries. It is used as a binder in monolithic refractories, industrial cleaning agents, preservatives, the soap and acid-proof cement, fine ceramics industry and casting industry, drying agent and enhancer, transport, storage and use very convenient, especially for mechanization and automation. Instant powdered sodium silicate products also have all the properties and applications of liquid sodium silicate has.
Analytical reagent, fire retardant, adhesive
1. besmear material surface, improve its resistance to weathering with density of 1.35g/cm³ sodium silicate impregnation or besmear clay brick, cement concrete, silicate concrete, stone and other porous materials, can improve the material density, strength, impermeability, frost resistance and water resistance.
2. Cement glass and calcium chloride solution are alternately injected into the soil, and the silicic acid gel generated in the humid environment is expanded due to the absorption of water in the soil, so that the soil is consolidated.
3. Preparation of quick-setting water-proofing agent.
4.repair brick wall crack will be sodium silicate, granulated blast furnace slag powder, sand and sodium fluosilicate mixed in an appropriate proportion, directly pressed into the brick wall crack, can play a bond and reinforcing effect.
5.sodium silicate aqueous solution can be used as the outer surface of the fire door.
6. It can be used to make acid-proof cement for lining of furnace cellar. Physical and chemical properties.
7.preparation of silicagel.
