Microsilica Powder (scientific name "silica fume," Micro-silica or Silica Fume), in the smelting of ferrosilicon and industrial silicon, silicon through the flue gas emitted by steam oxidation, the specially designed filter collected the amorphous powder like silica (SiO 2).Microsilica fume average 0.1-0.15 μ m in diameter, the size of several cement average 1.0%. Surface area for the 15-27 m 2 / g, with strong surface activity.
Steel and foundry: Blast furnace troughs and runners, ladle linings, sliding gates, etc.
Cement: Preheater linings, lining in the chain system and lining of in- and outlet zones of rotary kilns .
Glass and ceramics: Kiln furniture
1) Cementitous Repair Products (Mortars & Grouts) Low permeability, increase resistance from chlorides, acids, nitrates and sulfate etc
2) Oil Well Grouting Increase durability and compressive strength, decrease permeability, better control of gas leakage
3) Concrete Tile, roofing & wallboard,panels Lightweight and improve the strength
4) other application, such as waterglass industry, thermal insulation material etc.
Packaging Details: Microsilica powder is in water-proof plastic woven bag, jumbo bags&your requirements. Delivery Time: Within 20 days after receipt of prepayment. Remark: Chemical composition and size can be optimized by the customers' requirements
