Application areas of micro-silica powder

1 ﹑ used in mortar and concrete: high-rise buildings, seaports, reservoirs, dams, water conservancy, culverts, railroads, highways, bridges, subways, tunnels, airport runways, concrete pavement, and coal mine roadway anchor spray reinforcement.

2 ﹑ material industry:

(1) high-grade, high-performance low cement refractory castables and prefabricated parts, the service life is three times that of the ordinary castables, refractoriness increased by about 100 ° C, high-temperature strength and resistance to thermal shock performance have been significantly improved. It has been widely used in coke oven, iron making, steel making, steel rolling, non-ferrous metal, glass, ceramics and power generation industries. (2) Large iron ditch and ladle material, breathable bricks, coated repair material, etc..

(3) Self-flowing refractory casting materials and dry and wet method of spraying construction applications.

(4) Oxide bonded silicon carbide products (ceramic kiln kiln furniture, flame separator plate, etc.).

(5) high-temperature calcium silicate lightweight insulation materials.

(6) corundum mullite push plate for electric porcelain kiln.

(7) High-temperature wear-resistant materials and products.

(8) Corundum and ceramic products.

(9) Cylon bonded products. At present, in addition to the cast refractories in general use, in the electrofusion and sintered refractories also gained a large number of applications.

3, new wall materials, finishing materials: (1) wall insulation with polymer mortar, thermal insulation mortar, interface agent. (2) cement-based polymer waterproofing materials. (3) Lightweight aggregate thermal insulation and energy-saving concrete and products. (4) Putty powder processing for internal and external wall construction.

4. Other uses:

(1) Silicate brick raw materials.

(2) Production of water glass.

(3) Used as reinforcing material for organic compounds. Because its composition is similar to the silica produced by vapor phase method. It can be used in rubber, resin, paint, paint, unsaturated polyester and other polymer materials as filler reinforcing materials. (4) Used as anti-caking agent in fertilizer industry.
