What is potassium silicate? Potassium silicateis colourless 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.
Use of potassium silicate Protective coating (to prevent "frosting", that is, salt surface crystallization), catalyst, adhesive. It is used as a detergent in the manufacture of glass and ceramics. The phosphor adhesive is stuck on the picture tube and coated on the outside of the welding rod, which can overcome the splash. It is used as a reducing dye, fire retardant, welding electrode adhesive and inorganic coating adhesive. It can also produce soap, medicine, refractory materials, etc.
Preparation of potassium silicate Melting method: Mix silica sand and caustic potash in proportion and add them to the melting furnace. Heat them with heavy oil or electricity to 1200~1400 ℃. When a completely molten transparent body is formed, release it from the furnace for cooling and solidification, and then put it into the autoclave. Apply pressurized steam (0 2MPa). Let the solution stand and clear, remove impurities, and concentrate the clear solution to obtain a potassium silicate finished product.
Safety of potassium silicate It shall be packed in iron drums or plastic drums with a net weight of 300kg each. It shall be stored in general warehouses or tanks. The air temperature during storage and transportation shall not exceed - 5 ℃. The containers must be sealed and protected from rain. They shall not be stored and transported together with acid articles. In case of fire, water and various fire extinguishers can be used to put out the fire.
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.
