If you want to produce good quality white carbon black, you must start with product design, production process, production environment and production supervision, but the quality and ethics of employees are also decisive factors. Only by establishing a benign mechanism can good quality white carbon black products be produced. There are three main methods for producing white carbon black:

*** species: chemical vapor deposition method. We also call it pyrolysis, dry or combustion. The raw materials are silicon tetrachloride, oxygen (or air) and hydrogen, which are produced through high-temperature reactions. The reaction formula is:

SiCl4+2H2+O2=SiO2+4HCl

The second type: precipitation method is also called sodium silicate acidification method. A water glass solution is used to react with an acid, and white carbon black is obtained by precipitation, filtration, washing, drying and calcination. The reaction formula is:

Na2SiO3+2H+—>White carbon black+2Na++H20

The third type: the new method mainly uses non-metallic minerals and their extensions as silicon sources. The white carbon black is prepared by the precipitation method. The key to the technology is to transform crystalline silicon dioxide and silicate into amorphous silicon dioxide. The raw materials mainly include wollastonite, opal, halloysite, olivine, snakestone, kaolin, hard kaolin, coal gangue, fly ash, etc.

At present, the precipitation method is used to produce white carbon black, and most domestic production enterprises use the precipitation method. For specific production methods, you need to refer to related materials and production practices. In addition to selecting the right production method to produce a good white carbon black, only through practice.
