 Silica - Production Process 1. decomposition of sodium carbonate and precipitated silica second filter ultrafine silica, silica, and then within a chamber filter press filtration, washed with water until the sex; 2. the silica filter box removed within anti-caking agent silicon dioxide, silicon dioxide films by refining beating, and after acid precipitation eight hours, and the third with a box-type press filter machine and filtered to remove salt, in more than 300 ℃ hot air drying system drying, you can get more than 325 mesh, 325 mesh silica senior ultrafine activity of two varieties; 3. D or above have Two varieties of advanced ultra-fine silica, at 800--1000 ℃ high temperature oven drying can get instead of fumed silica produced products. Nano-silica (English title nano-silicon dioxide) is an inorganic chemical materials, commonly known as silica. Since the ultrafine nanometer size range 1 ~ 100nm, and therefore has many unique properties, such as against ultraviolet rays having optical properties, other materials can be improved aging, strength and chemical resistance. Very versatile. Nanoscale silicon dioxide as an amorphous white powder, non-toxic, tasteless, non-polluting silica microstructure spherical, quasi-particle structure was fluff and mesh, molecular formula and structural formula SiO2, insoluble in water.
