1. Instruction
(1) Microsilica, also called silica fume or micro silica, is a byproduct of producing silicon metal or ferrosilicon alloys.
Silicon metal and alloys are produced in electric furnaces. The raw materials are quartz, coal, and woodchips.
(2) The smoke that results from furnace operation is collected and sold as silica fume, rather than being land filled.
(3) Silica fume consists primarily of amorphous (non-crystalline) silicon dioxide (SiO2), its average granule diameter is 0.15~0.20 µ M, specific surface area is 15000~20000 m2/kg, and it has extremely strong surface active.
(4) Microsilica can be used in a variety of cementation products, such as concrete, grouts, and mortars as well as elastomeric, polymer, refractory, ceramic and rubber applications.
(5) HS No.: 28112200 China Origin, microsilica meets the requirements of ASTM C-1240.
Microsilica CAS #: 69012-64-2
2. Main function
(1) Microsilica in refractory enhancing the fluid of pouring refractory, reducing the volume of used water, be easy to shape, and raising the production efficiency.
(2) Because of its ultra microstructure for gap filling, the co***ct and intensity of refractory gain rising by a wade margin.
(3) Microsilica in refractory is a highly effective pozzolanic material, so it's easy to come into being Mullet Phase, under the premise that Al2O3 exists, enhance elevated temperature strength and thermal shock of refractory.
(4) Microsilica in refractory is used in Microsilica in refractory is used in unshaped, shaped gunned refractory materials to improves adhesion in castables and minimizes rebound loss. |
