What is sodium silicate powder? Sodium silicate powderhas strong adhesion, high strength, good acid resistance, good heat resistance, poor alkali resistance and good water resistance. Na2SiO3 9H2O, molecular weight 284.20, colorless orthogonal bipyramidal crystals or white to off-white mass or powder. It loses six molecules of crystalline water during weathering. Soluble in water, dilute sodium hydroxide solution, insoluble in alcohol and acid. Its melting point is 1088. Low toxicity, LD50(oral to rats)1280mg/kg(without crystalline water). Store in a cool, dry place. It's an acid oxide; Silicic anhydride has stable chemical properties. Insoluble in water, does not react with water, does not react with ordinary acids. It can react with hydrogen fluoride gas or hydrofluoric acid to form silicon tetrafluoride gas. At room temperature, the strong alkali solution reacts slowly with sio2 to form the corresponding silicates. Strong alkali solutions will eat glass, so glass bottles containing strong alkali solutions should not use frosted glass stoppers. If a glass stopper is used (glass contains sio2), sticky sodium silicate is produced to bond the glass stopper to the mouth of the bottle. Glass bottles cannot be kept with concentrated alkali for a long time.
Use of sodium silicate powder 1. Repair the cracks in the brick wall. Mix water glass, granulated blast furnace slag powder, sand, and sodium fluorosilicate in proper proportion and press them directly into the cracks in the brick wall, which can play a role of bonding and reinforcement 2. Sodium silicate aqueous solution can be used as the outer surface of fire doors 3. It can be used to make acid-resistant cement and used for the lining of furnace cellar 4. Prepare silica gel.
Preparation of sodium silicate powder Sodium carbonate method: according to the module requirements of the required products, the sodium carbonate (Na2CO3) and quartz sand (SiO2) with a particle size of 0.180~0.250 mm (60~80 mesh) are mixed evenly in proportion and sent into the horseshoe flame kiln, and fused at 1450~1500 ℃. The high-temperature molten products flow out from the kiln outlet and are pressed into blocks or water quenched into particles through the rollers on the mold.
Price of sodium silicate powder Sodium particle size and purity will affect the product's Price, and the purchase volume can also affect the cost of Sodium. A large amount of large amount will be lower. The Price of Sodium can be found on our company's official website.
