What is potassium silicate? Potassium silicate is hygroscopic and has a strong alkaline reaction. Of silica in the acid. Slow soluble in cold water or almost insoluble in water (depending on its composition) and insoluble in ethanol. In the stable state, the material is a viscous liquid, bluish-green, the aqueous solution of potassium silicate has colloid properties, and light scattering will occur in the storage process. Light scattering is the characteristic of colloid particles, indicating that the aqueous solution is constantly produced with new colloid particles in the storage process. Easy soluble in water and acid, the higher the potassium content, the more soluble.
Main uses of potassium silicate Potassium silicate is usually used to manufacture zinc-rich primers, inorganic paint, cement plate binder, and fire retardant agent. Potassium silicate can also be used in the manufacture of electric welding electrode, welding electrode, reducing dye, fire retardant agent; also as a phosphor binder and soap filler; also for the manufacture of electric welding electrodes, welding electrode, reducing dye and waterproof agent; and also as a quick coagulant in concrete admixture. What are the synthesis methods of potassium silicate are: First, by melting, the silica sand and caustic potassium can be added to the furnace in a certain proportion and heated with heavy oil or electric heat to 1200-1400℃. When a completely melted transparent body is formed, it will be put into the autoclave after forming and dissolved with a pressurized steam of 0.2 MPa. Set the solution to clarify, remove impurities, and concentrate the finished potassium silicate. Secondly, potassium silicate can also be prepared by potassium feldspar. Mix potassium feldspar, ammonium fluoride, and 98% sulfuric acid in a certain proportion and Reactions were performed at 190 to 250℃ and spontaneous pressure. Get potassium feldspar decomposition residue and contain SiF4 decomposition gas; Dust removal for the decomposed gas containing SiF4. Then the aqueous ethanol solution is used to generate fluorosilicic acid and silica precipitation; Use the dilute sulfuric acid solution to extract the potassium feldspar decomposition residue to obtain the extraction solution; Adsorbed to the extraction solution to obtain a potassium sulfate solution. Adding the fluorosilicic liquid obtained on top, Finally generated potassium fluorosilicate precipitation. After aging, Potassium fluorosilicate is produced by the filter press, filtration, and washing; A thermal potassium hydroxide solution was then added to the solution, To generate a potassium silicate solution containing potassium fluoride crystals, finally, after purification, separation, and concentration.
