Silica fume as fibre cement additive

Blogs, Refractory
Microsilica, or silica fume, is an amorphous type of silica dust mostly collected in baghouse filters as by-product of the silicon and ferro-silicon production. Microsilica consists of spherical particles with an average particle size of 150 nm and a specific surface area of typically 20 m2/g. The chemical and physical…

The main raw material of ultra-thin vacuum insulation board is micro silica fume, which has excellent thermal insulation and energy saving effect, and low thermal conductivity. The effect is equivalent to 6-10 times more than other thermal insulation materials. 1-2 cm thick insulation board can reach 75% energy saving requirement,…
