Surface of coating material-sodium silicate powder
What does sodium silicate Powder mean?
High adhesion of sodium silicate powder is good for heat resistance and acid resistance. It loses six molecules crystalline water during weathering. It dissolves in water. It has an melting point of 1088. Low toxicity. LD50 for rats (oral) 1280 mg/kg (excluding crystal waters). 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 appropriate 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 (with sio2 within the glass) can cause sticky sodium silicate to form, binding both the bottle stopper as well as the 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 an autoclave. They then heat by steam directly. Once the pressure rises above 0.7 to0.8Mpa in the autoclave, it is time for the steam connection stop. 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 sodium silicate dust
1. You can brush the surface to enhance weathering resistance. The density is 1.35g/cm 3. Water glass that has been impregnated, coated, with clay bricks or cement concrete, silicate concrete and stone can increase compactness, strength and resistance.
2. Reinforced soil injections alternately water glass or calcium chloride solution to soil. Silicic acid gel generated from the soil consolidates soil under humid conditions because it absorbs any water present in soil.
3. Prepare a fast-setting waterproof agent.
