What is sodium silicate powder? There are two kinds of sodium silicate; the chemical formula Na2SiO3, the formula amount 122.00, is sodium metasilicate. The chemical formula Na4SiO4. Sodium silicate is a colorless solid with a density of 2.4g/cm3. It is dissolved in water to form a viscous solution, commonly known as water glass and bubble alkali. It is an organic adhesive. Solid sodium silicate is commonly known as water glass in the south and bubble alkali in the north. The aqueous solution of sodium silicate is generally known as water glass. Pure solid sodium silicate is a colorless transparent solid; the sodium silicate sold in the market mostly contains some impurities with a light blue color. Sodium orthosilicate is a colorless crystal with a melting point of 1291K (1088 ℃), which is rare. Water glass solution is alkaline due to hydrolysis (slightly stronger than soda ash). Because it is a weak acid salt, it can precipitate silicic acid in the presence of hydrochloric acid, sulfuric acid, nitric acid, and carbon dioxide. During storage, carbon dioxide should be closely prevented from entering, and Rubber stoppers shall be used to prevent the adhesion of ground glass stoppers. In industry, sodium carbonate and quartz are commonly used to co-melt to produce Na2CO3+SiO2 → Na2SiO3+CO2 ↑. The products often have light blue-green color due to ferrous salts. They are used as inorganic bonding agents (can be mixed with talcum powder, etc.), soap fillers, and acid-resistant concrete. After adding pigments, they can be used as exterior wall coatings and poured into the foundation soil of ancient buildings to make the soil firm to prevent collapse.
Preparation of sodium silicate powder Sodium chloride method: use sodium chloride (NaCl) and quartz sand as raw materials, mix quartz sand and sodium chloride evenly and melt them, and then inject steam to react to obtain sodium silicate and hydrochloric acid. This method is slow in reaction speed and is not used in general factories.
Use of sodium silicate powder Analytical reagents, flame retardants, and adhesives. a. Coat the surface of the material to improve its weather resistance. Soak or coat porous materials such as clay bricks, cement concrete, silicate concrete, and stone with water glass with a density of 1.35g/cm to improve the compactness, strength, impermeability, frost resistance, and water resistance of the material. Reinforce the soil. Inject water glass and calcium chloride solution into the soil alternately by pressure; the generated silicic acid gel is in a state of expansion due to the absorption of water in the soil so that the soil is consolidated.
Price of sodium silicate powder Molybdenum Silicide particle size and purity will affect the product's Price, and the purchase volume can also affect the cost of molybdenum Silicide. A large amount of large amount will be lower. The Price of molybdenum Silicide can be found on our company's official website.
