White carbon black is white powder X- ray amorphous silicic acid and silicate products, is the main means of precipitated silica, 

 fumed silica, ultrafine silica gels and aerogels, including powdered synthetic aluminium silicate and calcium silicate. Silica is a po

-rous material, its composition by SiO2· nH2O, where nH2O is the surface hydroxyl groups form. Soluble in caustic and hydrofluoric

 acid, insoluble in water, solvent and acid ( except hydrofluoric acid). High temperature resistant, incombustible, tasteless, odorless, 

has a very good electrical insulation.

According to the production method of white carbon black is precipitated silica and fumed silica. Fumed silica normal white amorphous

 floc translucent solid colloidal nanoparticles (particle size less than 100nm ), non-toxic, has great specific surface area. Fumed silica is na

-no silica, purity 99%, particle size is 10~20nm, but the process is complex, expensive; precipitated silica is divided into traditional precip

-itated silica and special precipitated white carbon black, the former refers to the sulfuric acid, hydrochloric acid, CO2and water glass as 

basic raw materials production silica, the latter refers to the use of high gravity technology, sol-gel method, chemical crystal method, two

 crystallization method or reverse microemulsion method and other special methods for the production of silica. Precipitated silica is mai

-nly used for natural rubber and synthetic rubber reinforcing agent, toothpaste friction agent. Fumed silica is mainly used as silicone rubber

 reinforcing agent, coating and unsaturated resin thickening agent, superfine silica gel and the gel is mainly used as a matting agent for coat

-ings, thickening agent, plastic film opening agent.

Use: widely used in daily necessities, rubber products, adhesives, coating matting agent, filler, defoaming agent, food additive, feed, cosmetics,

 paint, paint and other industries

The fineness of product requirements:

In order to achieve the production of the fineness requirements, such as D50= 10µ m or D50= 5µ m, we use fluidized bed opposed jet mill QWJ. 

system through the special design, finer product requirements can be achieved.
