You
can buy refractory micro silica from Bemsun, whom it is provide
certificated MSDS undensified refractory micro silica in China with
the third party guaranteed.
1. Introduction of Refractory Micro
Silica
is a byproduct of producing silicon metal or ferrosilicon
alloys. Mine electric furnace generates mass very reactive
SiO2 and Si gas. The gas was oxidation and condensation
precipitation with air rapidly.
2. Refractory Micro Silica
main features:
* High early strength
* Greater impermeability
* High ultimate compressive strengths
* Substantially greater resistance to corrosion
3. Specification -
Refractory Micro silica
SiO2: *7%
Fe2O3: 0.2%
Al2O3: 0.1%
LOI: 3%max
Mositure: 1.5%
Specific surface: *8kg/m2
Bulk Densify: ******0kg/m3
4. Undensified Refractory
Micro Silica Application
Micro silica admixure is used in
refractory material
A. Traditional refractories have numerous pores. Microsilica can
fill the pores, improve the bulk density and reduce porosity, and
then strength is enhanced obviously.
B. Undensified Micro silica have strong activity, it can be
colloidal particles with water. Adding appropriate amount of
dispersant, it can help improving mobility and pouring
performance.
C. Undensified Microsilica can react with water to —Si-OH, it is
with high hydrophilic active. It can enhance the cohesion of
refractories and improve the high temperature performance. Besides,
it can extend the refractories life.
D. Undensified Micro silica instead of purity aluminum oxidation
mud for refractories and then save much cost.
