Silica sol is a colloid formed by silica nanoparticles in water, odorless, non-toxic, milky white color. Fine silica colloidal particles size is 10-20 nm with high specific surface area. The particles are transparent, so they will not affect the color of the covered material. If mix silica sol with other substances, the dispersion and permeability are very good. When the silica sol evaporates, the colloidal particles firmly adhere to the surface of the material and form silica-oxygen bonding between the particles, which is a good adhesive.
Application field of silica sol:
1.It is used for coating, improving the hardness and quick drying performance of the coating, and improving its high temperature, corrosion resistance,Water resistance. 2.It is used in industries with high requirements for particle size uniformity and high surface activity for papermaking, so as to improve paper fiber.The adhesion rate and adhesion of dimension can be applied to the paper and lifted for the post-treatment of finished paper.High gloss and ink absorption, used in corrugated paper, can improve its friction resistance. 3.It is used for precision casting and shell making process, and the shell is resistant to high temperature to 1640 , and the shell making strength is improved. 4.It is used for ceramic surface treatment, so that polishing brick, marble brick, quartz brick and so on can improve the surface gloss and pollution resistance. 5.It is used for the molecular sieve catalysts such as oil and coal to form the main molecular framework of the catalyst carrier. 6.For refractories, such as for glass, refractory for wires, and in refractory fibers.
7.For battery: the service life of ordinary lead-acid battery is short, and it can be configured as solid if it is used the electrolyte of the battery greatly improves the service life of the battery, effectively prevents the leakage and overflow of sulfuric acid, and avoids the pollution of the environment.
8.For textile industry: it can be used as sizing aids for diameter spinning to reduce the breakage rate. It can prevent yarn from slipping, keep fabric straight, dry and control the luster of the fabric. In the dyeing of fabrics, because of its adhesion, it can form excellent protective liquid and increase the adhesion of dyeing. 9.It can be used as food clarifier to deal with the settlement of soy sauce, fruit vinegar and juice beverage. 10.For CMP polishing, for stainless steel, metal, glass, sapphire, silicon wafer and chip surface to flatten it.
