Product Description

 

Microsilica  is also called silica fume or agglomerated silica fume. When iron alloy is used to smelt ferrosilicon and industrial silicon (metal silicon), a large amount of highly volatile SiO2 and Si gas is generated in the ore furnace, and the gas is discharged and air. Rapid oxidation and condensation precipitation. It is a by-product of large-scale industrial smelting. The whole process needs to be recycled by dust-removing environmental protection equipment. Because of its low density, it needs to be encrypted with encryption equipment.

Application

 

White silica fume is mainly used in amorphous refractory materials, construction, ceramics, pigments, chemicals, etc.

 

Construction field:

White silica fume can reduce the dosage of cement in concrete.

White silica fume can eliminate material segregation.

White silica fume can enhance concrete strength

White silica fume can improve abrasion resistance and durability.

White silica fume can increase corrosion resistance of rebar.

 

Refractory field:

White silica fume can effectively reduce water addition and its good thixotropy has combination function in low temperature, hence it is the best binding agent, additive and performance improving admixture.

 

Other fields:

 

In the amorphous castables,white silica fume is  used for steel ladle.It has the function of high temperature resistance and heat preservation of liquid steel.

 

When white silica fume is used in high-alumina brick, magnesite brick, slide gate brick, furnaces, and refractory materials in other high-temperature equipment, it will improve the quality level of product, and bears the functions other ordinary refractories are incapable of.

Winitoor information

 

Quanzhou Winitoor Industrial Co.,Ltd has been in microsilica(a powder),mainly

for concrete and refactory since 2004.

 

Our standard products are densified microsilica from SiO2 85% to 94%,mostly used

type is 85%SiO2 and 92%SiO2;

undensified microsilica for refractory from SiO2 92% to 97% SiO2,mostly used type is 94%

SiO2 and 96% SiO2,97% SiO2 is very less capacity for microsilica suppliers.

 

We have exported thousand tons of densified and undensified microsilica to different countries.

Our quality is under control of the ISO 9001 certificate and meeting the standard of ASTM C1240

with a third-party test quality guanranteed.

Besides,we have a well-conditioned warehouse to store our microsilica to keep a stable quality and

keep a enough capacity for our customers.
