Inorganic silica gel is a highly active adsorption material, which is usually prepared by a series of post-treatment processes such as reaction of sodium silicate with sulfuric acid, aging, acid bubble and so on. Insoluble in water and any solvent, non-toxic, tasteless and stable in chemical properties. Except for strong alkali and hydrofluoric acid, it does not react with any substance and can be washed off with alcohol.
Silica gel is a kind of organosilicon compound, which refers to a compound containing Si-C bond and at least one organic group directly connected with silicon atom. Traditionally, those compounds that connect organic groups with silicon atoms through oxygen, sulfur, nitrogen, etc. Also known as organosilicon compounds. This silica gel can be dissolved in natural water and white oil.

Use of liquid silica gel:
Liquid silicone rubber can be used for trademarks, products, nipples, medical supplies, coating, dipping and pouring. Silica gel products, such as molding molds, injection molding processes, cake molds, etc. Used in crystal glue, polyurethane, epoxy resin, etc. It is widely used as moisture-proof, consignment and insulation coating and potting material for electronic components in the electronic industry, and plays a role in dustproof, moisture-proof, shockproof and insulation protection for electronic components and components.
If the electronic components are encapsulated with transparent gel, it can not only play the role of shock prevention and waterproof protection, but also see the components, and use the probe to detect the faults of the components and replace them. Damaged silica gel can be encapsulated and repaired again.
It can also be used to make molding dies for gypsum, wax, epoxy resin, polyester resin, polyurethane resin and low-melting alloy products, and can be used for high-frequency embossing of artificial leather, modeling of the top and bottom of shoes, manufacturing of handicrafts, ceramics, toy industry, copying of furniture, household appliances and electronic components, molding of gypsum and cement materials, molding of wax products, manufacturing of models, molding of materials, etc.
