What is sodium silicate mainly used for?

What is Sodium silicate powder?
Sodium silicate powder is a kind of rapidly coagulating foaming alkali with cold resistance, uniformity, and convenient use, transportation, and storage. The molecular formula is na2onsio2 H2O.
Applications of Sodium silicate powders
Sodium silicate is widely used in almost all sectors of the national economy. In the chemical system, it is used to manufacture silica gel, white carbon black, zeolite molecular sieve, sodium metasilicate pentahydrate, silica sol, layered silicon, instant powdered sodium silicate, potassium sodium silicate, and other silicate products, which are the basic raw materials of silicon compounds.
Mainly used in the following fields:
1. Coat the surface of the material to improve its weathering resistance. Is the density 1.35g/cm? Soaking or coating porous materials such as clay brick, cement concrete, silicate concrete, and stone with sodium silicate can improve the compactness, impermeability, frost resistance, and water resistance of the materials.
2. Reinforcing the soil. Sodium silicate and calcium chloride solution are alternately injected into the soil to form a silicic acid gel. In a humid environment, the soil is in a state of expansion due to the absorption of soil moisture so that the soil is consolidated.
3. Repair the cracks in brick walls. After mixing sodium silicate, powdered blast furnace slag powder, sand, and sodium fluorosilicate in an appropriate proportion, they are directly pressed into the cracks in brick walls, which can play a role in bonding and reinforcing.
4. Sodium silicate aqueous solution can be used as the skin of fire doors.
5. It can be used to make acid-resistant cement, which can be used as furnace pit lining. Physical properties.
6. Preparation of silicone resin.
Precautions of Sodium silicate powder
1.Store in a dry, cool, and ventilated warehouse, and do not stack in the open air, with a shelf life of 3 years.
2.The molecular formula of sodium silicate (alias sodium silicate, sodium silicate) is Na2O. NSIO 2. XH2O. The properties of sodium silicate vary with the ratio of silica to sodium oxide in the molecule, which is called the modulus. When the modulus is above 3, it is called neutral sodium silicate, and when the modulus is below 3, it is called alkaline sodium silicate. Sodium silicate has two kinds of shapes: solid and liquid, and liquid is the most common commodity. The liquid sodium silicate is a colorless, bluish-gray, reddish transparent, or translucent viscous liquid which can be dissolved in water. Sodium silicate aqueous solution has viscosity, especially high modulus viscosity. In the case of acid, the colloidal precipitate of silicic acid is decomposed and precipitated. Solid sodium silicate is a blue or yellow-green glassy substance, and its relative density increases with the decrease of modulus. When the modulus decreases from 3.33 to 1, its relative density increases from 2.413 to 2.560. No fixed melting point.
Price of Sodium silicate powder
Sodium silicate powder particle size and purity will affect the product's price, and the purchase volume can also affect the cost of Sodium silicate powder. A large amount of large amount will be lower. The price of Sodium silicate powder can be found on our company's official website.
