What is sodium silicate? The mixing ratio of sodium silicate quartz sand and alkali, i.e., the molar ratio of SiO2 and Na2O, determines the modulus n of sodium silicate, which shows the composition of sodium silicate. The modulus is an important parameter of sodium silicate between 1.5 and 3.5. The larger the modulus is, the more difficult the solid sodium silicate is to be dissolved in water. When n is 1, it can be dissolved in normal-temperature water. When n is increased, it can be dissolved in hot water. When n is greater than 3, it can be dissolved in more than 4 atmospheres of steam. The larger the modulus of sodium silicate is, the more silicon oxide content is, the higher the viscosity of sodium silicate is, the easier it is to decompose and harden, and the higher the adhesion is. Therefore, sodium silicate with different modulus has different uses. It is widely used in ordinary casting, precision casting, paper making, ceramics, clay, mineral processing, kaolin, washing, and many other fields.
Use of sodium silicate Paint the material surface to improve its weathering resistance with a density of 1.35g/cm ³ Water glass impregnated with or coated with clay bricks, cement concrete, Portland concrete, stone, and other porous materials can improve the compactness, strength, impermeability, frost resistance and water resistance of materials The reinforced soil injects water glass and calcium chloride solution into the soil alternately. The generated silicic acid gel consolidates the soil under a humid environment because it absorbs the water in the soil and is in an expansive state. A quick-setting waterproof agent has prepared Repair the cracks in the brick wall. After mixing sodium silicate, granulated blast furnace slag powder, sand, and sodium fluosilicate in proper proportion, directly press them into the cracks in the brick wall, which can play the role of bonding and reinforcement. Sodium silicate water solution can be used as the external surface of fire doors. It can be used to make acid-resistant mastic and as the lining of furnaces.
Application of sodium silicate as water glass The use of water glass is very extensive, 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, and is the basic raw material of silicon compounds In economically developed countries, there are more than 50 kinds of deep-processing products using sodium silicate as raw material, some of which have been used in high, fine and cutting-edge scientific and technological fields; In light industry, it is an indispensable raw material for detergents such as washing powder and soap, as well as a water softener and sedimentation aid; Used in the textile industry for dyeing, bleaching and sizing; In the machinery industry, it is widely used in casting, grinding wheel manufacturing, metal preservatives, etc; In the construction industry, it is used to manufacture quick drying cement, acid resistant cement waterproof oil, soil curing agent, refractory materials, etc; In agriculture, it can produce silicon fertilizer; In addition, it can be used as silicon aluminum catalyst for oil catalytic cracking, filler for soap, adhesive for corrugated paper, laboratory crucible and other high temperature resistant materials, metal preservatives, water softeners, detergent additives, refractory materials and ceramic raw materials, bleaching, dyeing and sizing materials for textiles, mineral processing, waterproof, leak stoppage, wood fire prevention, food anti-corrosion and adhesive making.
Price of Sodium silicate Sodium silicate particle size and purity will affect the product's Price, and the purchase volume can also affect the cost of sodium silicate. A large amount of large amount will be lower. The Price of sodium silicate can be found on our company's official website.
