Fumed Silica is produced with the method of gas phase . Its theory is burning the chloride under oxvhydrogen flame and high- temperature vapor
phase hydrolysis, and collected finished product after refining process of condensation, separation, deacidification and screening.
Fumed silica, commonly known as "fumed white carbon black", is widely used in various industries as additives, catalyst carriers, petrochemicals, decolorizers, matting agents, rubber reinforcing agents, plastic fillers, ink thickeners, metal soft Sexual polishing agent, insulating filler, advanced daily cosmetic filler and spraying material, medicine, environmental protection and other fields. It also provides a new material foundation and technical guarantee for the development of related industrial fields.
