What is potassium silicate? Potassium silicate is also known as potassium metasilicate. It can be divided into three types: ① K2SiO3=154.29, colorless crystal, usually greenish green blocky or glassy solid The melting point is 976 ℃. It is soluble in water and is easily soluble in hot water or under pressure. The aqueous solution is alkaline and insoluble in ethanol. In the case of acid, it decomposes and precipitates silicic acid gel. It deliquesces by absorbing water in the air. ② K2Si2O5=214.37, colorless rhombic crystal. The relative density is 2.456 (25/4 ℃), and the melting point is 1015 ± 10 ℃. ③ K2Si4O9 · H2O=352.56, white rhombic crystal. The relative density is 2.417. It is decomposed when heated to 400 ℃. It is soluble in water and insoluble in ethanol. It is prepared by co-melting potassium carbonate or potassium hydroxide with quartz sand at a high temperature. Potassium silicate has hygroscopicity and a strong alkaline reaction Potassium silicate is easy to decompose and precipitate silicon dioxide in an acidic environment. Potassium silicate is usually used to manufacture welding electrodes, welding electrodes, vat dyes, fire retardants, fluorescent screen coating, and soap fillers. Therefore, potassium silicate has a wide range of applications. The elements in potassium silicate are similar to those in potassium feldspar, so it is of great significance to study how to use potassium feldspar to decompose to prepare potassium silicate.
Manufacture of potassium silicate glass Step 1: Put tetraethyl orthosilicate, water, and ethanol in a container and mix them into a homogeneous solution. Then add hydrochloric acid and KCl solution in turn under stirring conditions. Get mixed solution; Step 2: Put the mixed solution into the oven and conduct constant temperature treatment for 28-30h; Step 3: After the mixed solution forms a gel, reduce the oven temperature and conduct constant temperature treatment for 50~60h to obtain potassium silicate glass semi-finished products; Step 4: Take the potassium silicate glass semi-finished product out of the oven and place it in the crucible. Place the crucible in the oven at a temperature of 200~300 ℃. Then raise the oven temperature to 500~600 ℃. After constant temperature treatment for 2~3h, close the oven. Take it out after the potassium silicate glass semi-finished product is cooled to room temperature in the oven. The potassium silicate glass is obtained. It has high purity and uniformity, a simple preparation method, and low requirements for production equipment.
Preparation of a high modulus potassium silicate inorganic nano resin The preparation method, in turn, includes the mixing process of raw materials and the preparation process of high-modulus potassium silicate inorganic nano resin. The mixing process of raw materials is to add low modulus potassium silicate aqueous solution into the mixer, stir to form an eddy current, then add water, silica sol, stabilizer, and coupling agent in turn, mix evenly to obtain a prefabricated mixture. The preparation process of high modulus potassium silicate inorganic nano resin is first to heat the prefabricated mixture to 40~80 ℃. Then at this temperature, The heated prefabricated mixture circulates in the reaction system formed by a mixer, circulating pump, and high gravity rotating packed bed to obtain potassium silicate inorganic nano resin with a high modulus of 5.3~6.2, solid content of 26%~30%, the particle size of 5~20 nm and yield of 98.5%~99%. The above methods not only improve the product quality and storage stability but also shorten the reaction time and reduce energy consumption.
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.
