What does sodium silicate Powder mean?
High adhesion of sodium silicate powder is good for heat resistance and acid resistance. When it weathers, 6 molecules of crystalline liquid are lost. It dissolves in water. Its 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 (with sio2 in it) can cause sticky sodium silicate to form, binding both the glass bottle stopper & 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 the autoclave. They then heat by steam directly. Once the pressure rises above 0.7Mpa in the autoclave, steam is disconnected. 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, will improve 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 in humid environments 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 cost. 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.
