Introduction of silica powder for concrete
Silica powder for concrete (Microsilica or Silica Fume), is also known as microsilica, scientific name "silica fume", also known as silica fume, is an industrial furnace in the process of high temperature melting industrial silicon and ferrosilicon, with the smoke emitted by the exhaust gas by special The trap is collected and processed. The scientific name “silica fume”, Microsilica or Silica Fume, is the industrial electric furnace in the process of high-temperature melting industrial silicon and ferrosilicon. The fumes emitted by the exhaust gas are collected and processed by a special trapping device. In the soot emitted, the SiO2 content accounts for about 90% of the total amount of soot, the particle size is very small, and the average particle size is almost the nanometer level, so it is called silicon powder.
The fineness specifications of silicon powder
|500um-180um||30 mesh - 80 mesh||+500um≤3% -180um≤10%|
|425um-150um||40 mesh-100 mesh||+425um≤5% -150um≤15%|
|250um-140um||60 mesh-110 mesh||+250um≤3% -140um≤10%|
|125um-74um||120 mesh - 200 mesh||+125um≤3% -74um≤10%|
|5um-1um||2500 mesh-12500 mesh||5um≤5%|
The role of micro-silica powder
The role of silca powder
silica powder Used for mortar and concrete buy silica fume:
high-rise buildings, harbor docks, reservoir dams, water conservancy culverts, public railway bridges, subways, tunnels, airport runways, rammed roads, and reinforcements for coal mine roadways.
silica powder In the material industry buy silica fume:
high-grade, high-performance, low-cement refractory castables and prefabricated parts, the service life is three times that of ordinary castables, and the refractoriness is increased by about 100°C.
The high-temperature strength and thermal shock resistance are improved significantly; they have been widely used: coke ovens , iron making, steel making, steel rolling, non-ferrous metals, glass, ceramics and power generation industries; large iron ditch and steel materials, breathable bricks, smear repair materials, etc.; self-flowing refractory casting materials and dry and wet spray construction applications; oxides Combined with silicon carbide products (ceramic kiln furniture, flame barriers, etc.); high-temperature calcium silicate lightweight insulation material; electric porcelain kiln with corundum mullite push plate. High-temperature wear-resistant materials and products; Corundum and ceramic products; Sialon bonded products; In addition to the general use of cast refractories, fused and sintered refractories have also been used in a large number of applications need silica fume.
silica powder used New wall materials and decorative materials buy siica fume :
Polymer mortar, insulation mortar and interface agent for wall insulation.
Cement-based polymer waterproof material buy silica fume .
Lightweight aggregate insulation and energy saving products need silica fume.
Interior and exterior wall construction putty powder processing need silica fume.
1 silica powder used in Silicate brick raw materials buy silica fume.
2 silica powder used in Production of water glass buy silica fume.
3 silica powder Used as a reinforcing material for organic compounds buy silica fume.
Its composition is similar to that of the silica produced by the gas phase process. It silica powder can be used as a filling reinforcing material in polymer materials such as rubber, resins, paints, paints, and unsaturated polyesters.
4 silica powder Used as an anti-caking agent in the fertilizer industry buy silica fume.
