White carbon black is the general name of white powdered X-ray amorphous silicate and silicate products, mainly refers to pre

-cipitated silica, vapor silica, ultra-fine silica gel and gas gel, but also includes powdered synthetic aluminum silicate and 

calcium silicate, etc. Silica is a porous substance whose composition can be expressed by SiO2·nH2O, in which nH2O exists in 

the form of surface hydroxyl group. Soluble in caustic soda and hydrofluoric acid, insoluble in water, solvents and acids (except 

hydrofluoric acid). High temperature resistance, non - combustion, tasteless, no smell, with good electrical insulation.

According to production methods, white carbon black can be divided into precipitation white carbon black and gas phase white carbon

black. Gas phase white carbon black is normally white amorphous flocculent translucent solid colloidal nanoparticles (particle size 

less than 100nm), non-toxic, with a huge specific surface area. The gas phase white carbon black is all nano silica, the purity of 

the product can reach 99%, the particle size can reach 10~20nm, but the preparation process is complicated and expensive. Precipita

-tion method white carbon black is divided into traditional precipitation method white carbon black and special precipitation method 

white carbon black, the former refers to the production of sulfuric acid, hydrochloric acid, CO2 and sodium silicate as the basic raw 

materials, the latter refers to the use of high gravity technology, sol-gel method, chemical crystal method, secondary crystallization 

method or reverse micelle microemulsion method and other special methods of silica production. The precipitated white carbon black is 

mainly used as the reinforcing agent of natural rubber and synthetic rubber, toothpaste friction agent and so on. Vapor-phase white 

carbon black is mainly used as a reinforcing agent of silicone rubber, coating and unsaturated resin thickening agent. Superfine silica 

gel and air gel are mainly used as coating matting agent, thickening agent and plastic film opening agent.

Application: Used in daily necessities, rubber products, adhesive, coating matting agent, papermaking filler, defoaming agent, food and 

pharmaceutical additives, feed, cosmetics, pigments, paint and many other industries

Product fineness requirements: In order to meet production fineness requirements, such as d50 = 10µm or d50 = 5µm, we use fluidized bed 

colliding jet mill QWJ. Through the special design of the system,

More detailed product requirements can also be met.
