Silica sol manufacturers sell various alkaline silica sol production and sales

Description :

　　Silica sol is a dispersion of nano-sized silica particles in water or solvents. Due to the high content of water and hydroxyl groups in SiO2 in silica sol, silica sol can also be expressed as mSiO2. nH2O. There are different ways to prepare silica sol. Common methods include ion exchange, one-step hydrolysis of silicon powder, silane hydrolysis, etc.

　　1. Precision casting: used for precision casting of thin shells, which can increase the strength of the shell shape and improve the casting smoothness. Using it for styling is of better quality than water glass styling, and replacing silicone resin styling can reduce costs and improve operating conditions.

　　2. Paper industry: Silica sol is commonly used as a release agent in the production of glass paper. After mixing silica sol with photosensitive solution, the photosensitive paper surface can be smoothed, the image can be vivid, and the exposure range can be increased.

　　3. Coatings: Exterior wall coatings with added silica sol have good washability and corrosion resistance, and reflect softer light.

　　4. Refractory materials: used as binders for various refractory materials, with strong bonding strength and high temperature resistance (1500-1600 ℃).

　　5. Woolen industry: used as a paddle agent in the textile industry, it is combined with oil agents to treat wool and rabbit hair, which can improve the spinnability of wool and rabbit hair, reduce breakage, prevent flying flowers, increase product yield, and increase economic benefits.

　　6. Silica sol is also used in many applications such as acidic batteries, catalysts, water purifiers, and cathode ray tube coatings
