Application

Fumed silica is the superfine micro-nano fine chemical product, which is divided into hydrophilic type and hydrophobic type in accordance with their different surface treatments. Its appearance

is white powder. Native particle size ranges from 5nm to 40nm, with significant functions of thixotropy, reinforcing, thickening and filling. Therefore, it is widely used in the industries of rubber, sealant, plastic, resin, paint, printing ink, papermaking, medicine, cosmetics,

food etc.

Fineness:

Silicon fume belongs to superfine solid powder and the average particle size is is about 0.10.15μm.

Fire resistance

(SiO290%) Its melting point can reach 1630.

Grain shape

Its appearance is spherical on storey and the surface is relatively smooth.And

it can reduce the frictional force among particles because of the lubricated

function.

Mineralogical structure

It condensates rapidly. It's an important cement and concrete addition

and additive in cement mould.

Comprehensive utilizations:

Used as cement batching in building material line, it can improve the compressive strength, bond

strength, abrasion resistance and reduce permeability.

In chemical line, it's used in precision ceramic and high performance powder metallurgy. Also used as

basic raw material for silicic acid composition and an important filling in organic compound.

Used in fertilizer and to improve soil quality.

Used in mortar and concrete, it can fill apertures among particles and reduce the content of Ca(OH)2, making mortar and concrete compact and even.
