Basic Info.

Model NO.
Silica black is the general name of white powder X-ray amorphous silicic acid and silicate products, mainly refers to precipitated silica, gas phase silica, ultrafine silica gel and aerogel, also including powder synthesis of aluminum silicate and calcium silicate.Silica is a porous material whose composition can be represented by SiO2•nH2O, where nH2O exists as a surface hydroxyl group.Soluble in caustic soda and hydrofluoric acid, insoluble in water, solvents and acids (except hydrofluoric acid).High temperature resistance, non-flammable, tasteless, odorless, with good electrical insulation.
Silica is generally divided into precipitation silica and gas phase silica according to production methods.Under normal condition, the vapor phase silica is white amorphous and flocculent translucent solid colloidal nanoparticles (particle size less than 100nm), which are non-toxic and have a large specific surface area.Gas-phase silica is all nano-silica, with purity up to 99% and particle size up to 10-20nm. However, the preparation process is complicated and the price is expensive.Is divided into traditional of precipitated silica and special precipitation of precipitated silica white carbon black, the former refers to sulfuric acid, hydrochloric acid, CO2 and water glass as the basic raw material to produce the silica, the latter refers to the supergravity technology, sol-gel, chemical crystal method, secondary crystallization or reverse micellar microemulsion method and other special production of silicon dioxide.Precipitated silica is mainly used as reinforcing agent for natural rubber and synthetic rubber, toothpaste friction agent, etc.Gas-phase silica is mainly used as a reinforcing agent, coating and thickening agent of unsaturated resin for silicone rubber, while ultrafine silica gel and gas-phase silica gel are mainly used as coating matting agent, thickening agent and plastic film opening agent.
