The USA Customer 400 Tons White Silica Fume With ASTM C1240 Standard Order Has Ready Make,just For Packaging And Send To The Customer

- May 24, 2018 -

Recently,our old customer microsilica from USA,requiring 400 tons of white silica fume with ASTM C 1240 standard.Now we have finish them and wait for packaging and delivery to USA.


Do you know what white silica fume is?Let us get together to know more about it.

White silica fume is aslo a  byproduct recycled during the production of desilicated zirconia via electric smelting,producing through advanced technique of electric melting method.Theproduct is of fine particle size,

big specific surface area, good liquidity and high SiO2 content, which realize the recycling of resources.

Application of white silica fume

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

 

1In the construction:

 in cement concrete:

reduce the dosage of cement in concrete

eliminate material segregation

enhance concrete strength

 improve abrasion resistance and durability

increase corrosion resistance of rebar.

 

2In the amorphous refractory materials:

 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.

 

3In the amorphous castables used for steel ladle, it has the function of high temperature resistance and heat preservation of liquid steel.

 

4When 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.
