1. Instruction
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. The smoke that results from furnace operation is collected and sold as silica fume, rather than being land filled. Silica fume consists primarily of amorphous (non-crystalline) silicon dioxide (SiO2), its average granule diameter is 0.15~0.20 µm,specific surface area is 15000~20000 m2/kg, and it has extremely strong surface active. 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. HS No.: 28112200 China Origin, microsilica meets the requirements of ASTM C-1240. Microsilica CAS #: 69012-64-22. Main function
Very low permeability to chloride and water intrusion. Extremely high electrical resistivity (20 to 100 times greater than ordinary concrete). Increased abrasion resistance on decks, floors, highways and marine structures. Superior resistance to chemical attack from chlorides, acids, nitrates and sulfates.3.JH92
Microsilica JH93 is a dry powder available in two forms,densified silica fume and undensified silica fume.
Microsilica JH93 is a pozzolanic materials that consisits primarily of fine silicon dioxide particles in a non-crystalline form.
Microsilica JH93 meets the requirements of ASTM C-1240 and contains a minimum of 93% silicon dioxide(SiO2).
Microsilica JH93:we have three factories in Shanxi,Yunnan and Qinghai Province,China.Stable quality and reasonable price.
