Why potassium silicate can be used as a protective coating?
What is potassium silicate?
Potassium silicate is colorless or yellowish, translucent to transparent glass, with hygroscopicity and a strong alkaline reaction. It is decomposed in acid and precipitates silicon dioxide. It is slowly soluble in cold water or almost insoluble in water (depending on its composition) and insoluble in ethanol. Potassium silicate is usually used to make welding electrodes, welding electrodes, reducing dyes, and fire retardants. It is also used as a fluorescent screen coating layer and soap filler. It is a transparent viscous liquid in a stable state, and It is blue-green, soluble in water and acid, and precipitates colloidal silicic acid. The higher the potassium content, the more soluble and insoluble in alcohol.
Synthetic method of potassium silicate
1. In the melting method, silica sand and caustic potash are mixed in proportion and then added into the melting furnace, heated to 1200~1400 ℃ with heavy oil or electricity. When a completely molten transparent body is formed, it is discharged from the furnace, cooled and solidified, and then put into the autoclave, dissolved by pressurized steam (0.2MPa). The solution is left to settle, impurities are removed, and the clarified solution is concentrated to obtain potassium silicate products
2. Melting method (i.e., dry method) is adopted. Silica sand and caustic potash are dissolved by pressurized steam after being used in the melting furnace.
Use of potassium silicate
Protective coating (to prevent "frosting," that is, salt surface crystallization), catalyst, adhesive, used as descaler in the manufacture of glass and ceramics. The phosphor adhesive can be stuck on the picture tube and coated outside the welding rod to overcome the splash. It can be used as a reducing dye, fire retardant, welding electrode adhesive, and inorganic coating adhesive. It can also produce soap, medicine, refractory materials, etc.
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.
