What is potassium silicate powder?

What is potassium silicate?
Potassium silicate is colorless or yellowish translucent to transparent glass. It is hygroscopic. There is a strong alkaline reaction. Decompose in acid to precipitate silica. Slowly soluble in cold water or hardly soluble in water (depending on its composition), insoluble in ethanol. Potassium silicate is usually used to make welding electrodes, welding electrodes vat dyes, and fire retardants. It is also used as a fluorescent screen coating layer and soap filler. In the stable state, it is a transparent viscous liquid, which is blue-green. Soluble in water and acid and precipitated colloidal silicic acid. The higher the potassium content, the more soluble it is. Insoluble in alcohol.
Instant potassium silicate is a white powdery substance that can be quickly dissolved in water. Its molecular formula is K2O·H2O·nsio 2, which depends on different specifications and different uses. It is a special foaming alkali with the characteristics of cold resistance, uniformity, convenient use, transportation, and storage.
Classification of potassium silicate
Potassium silicate is also known as potassium metasilicate. There are three types:
1.K2SiO3 = 154.29, colorless crystal, usually turquoise block or glassy solid. The melting point is 976. Soluble in water, easy to dissolve in hot water or under pressure. The aqueous solution is alkaline and insoluble in ethanol. The acid will decompose and precipitate silicic acid gel. Absorb water and deliquescence in the air.
2.K2si2o5 = 214.37, colorless orthorhombic crystal. The relative density is 2.456(25/4), and the melting point is 1015 10.
3.K2Si4O9·H2O=352.56, white orthorhombic crystal. The relative density is 2.417, and it decomposes when heated to 400. Soluble in water, insoluble in ethanol.
Applications of potassium silicate
Potassium silicate is widely used in anticorrosion, casting, oil fields, drilling, and various high-grade coatings. Potassium silicate is mainly used in acid-resistant, heat-resistant, wear-resistant, and other anti-corrosion projects and is made into acid-resistant and heat-resistant materials.
1.It can be made into engineering raw materials such as potassium sodium silicate (KP1) cement, potassium sodium silicate (KP1) mortar, potassium sodium silicate (KP1) concrete, etc., according to different uses. It has the advantages of high mechanical strength, high adhesive force, small void ratio, high impermeability and water resistance, good acid resistance (see cement page for details), good heat resistance, etc.
2.It also has corrosion resistance in alkaline media, fluorine-containing media, neutral salt solutions, and higher fatty acids. High-modulus potassium silicate is mainly used as a binder in advanced coatings. Potassium silicate protective coating (to prevent "frosting," that is, crystallization of salt surface).
3.Used as a detergent in catalysts, adhesives, glass, and ceramics.
Development of potassium silicate
China's oil drilling and development have gradually developed in recent years from shallow to deep and from simple to complex formations. Due to the high downhole temperature and pressure in deep and ultra-deep wells, especially in complex formations, the performance of downhole drilling fluid changes greatly, which is very likely to lead to some complex downhole situations (such as collapse, drill sticking, etc.), The main development direction of drilling fluid research is to seek new drilling fluid systems that can effectively inhibit formation expansion and stabilize wellbore. There are many strongly inhibitory water-based drilling fluids, such as potassium calcium-based drilling fluid or potassium calcium-based polyalcohol water-based drilling fluid. This type of drilling fluid has the advantages of strong inhibition, low cost, and easy maintenance and treatment. The inhibition of this type of drilling fluid mainly depends on the role of potassium-calcium inorganic salts; the effective concentration of potassium and calcium ions is an important indicator of the inhibition of drilling fluids. However, because there is no instrument to detect the concentration of potassium and calcium ions in the field, the actual content of potassium and calcium ions in drilling fluids is insufficient, which seriously affects the effectiveness of this kind of drilling fluids in preventing collapse.
Price of potassium silicate
Potassium silicate particle size and purity will affect the product's price, and the purchase volume can also affect the cost of potassium silicate. A large amount of large amount will be lower. The price of potassium silicate can be found on our company's official website.
