What does sodium silicate Powder mean? High adhesion of sodium silicate powder is good for heat resistance and acid resistance. It loses 6 molecules crystalline water during weathering. It dissolves in water. It has a melting point of 1088. Low toxicity. LD50 for rats (oral) 1280mg/kg. You should keep it dry and in a cool, dry location. It is an oxide of acid; the anhydride acid of silic acid has stable chemical characteristics. It doesn't dissolve in water; it does not react to water. Hydrofluoric acid or hydrogen fluoride can react to make silicon tetrafluoride. At normal temperatures the sio2 and the strong alkali mixture slowly react to create the silicate. Strong alkali solutions can cause glass to corrode so a stopper for glass bottles containing strong alkali must be used. Use of a glass stopper (containing sio2 within the glass) will result in sticky sodium silicate that will bind the bottle stopper and bottle mouth. Glass bottles cannot be used with concentrated alkali.

Prepare sodium silicate powder
By wet method, the silica and liquid caustic soda are combined in an appropriate proportion into the autoclave. They then heat by steam directly. Once the pressure rises above 0.7-0.8Mpa in the steam connection, it is shut down. Chemical book employs jacket steam as insulation. This pressure is maintained and the reaction takes place for many hours. Reactants are then filtered to make water glass. It is 2NaO+nSiO2 Na2O nSiO2+H2O.

Use of sodium silicate dust
1. You can brush the surface to enhance weathering resistance. Water glass with a density greater than 1.35g/cm3 is impregnated, coated or covered with clay bricks. Cement concrete, silicate concrete and stone are all porous materials that improve the compressibility, strength, stability, impermeability and water resistance.
2. Reinforced soil injections alternately water glass or calcium chloride solution to soil. Silicic acid gel generated from this process consolidates soil under the moist environment. It absorbs any water present in soil and retains it in an expanded state.
3. Prepare a fast-setting waterproof agent.
