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 6 molecules crystalline water during weathering. It dissolves in water. Its melting temperature is 1088. It is low in toxicity, LD50 (rats oral), 1280mg/kg. (Excluding crystal water). 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 glass bottle mouth and 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 an 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's Na2O+nSiO2 and 2NaO+nSiO2. nSiO2+H2O.
Use of sodium silicate dust
1. You can brush the material’s surface to enhance its weathering resistance. Water glass with a density of 1.35g/cm3 or more may be used.
2. Reinforced soil injections alternately water glass or calcium chloride solution to soil. Silicic acid gel generated from this process consolidates soil under 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 the Price for molybdenum Siicide.
