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. Its melting temperature is 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 strong alkali solution (and sio2) 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 that contains sio2 will cause sticky sodium silicate to form, which can then bind the bottle mouth and glass bottle stopper together. 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 0.70.8Mpa 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. Its 2NaO+nSiO2 Na2O nSiO2+H2O.
Use of sodium silicate dust
1. You can brush the material's surface to enhance its 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 the materials' compactness, strength and impermeability.
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.
The price of sodium silicate powder
Molybdenum Silicide's purity and particle size will impact the price. The purchase volume may also have an effect on the price. Large quantities of smaller amounts will result in a lower price. You can check out our website to find out the current price for molybdenum-silicide.
