Application Of Silicon Micropowder

2018-07-16

Silicon micropowder is a non-toxic, odorless, non-polluting inorganic non-metallic material. Because of its excellent temperature resistance, acid and alkali corrosion resistance, high thermal conductivity, high insulation, low expansion, stable chemical properties, and high hardness, it is widely used in chemical, electronic, integrated circuits (IC), electrical appliances, Plastics, coatings, advanced paints, rubber, defense and other fields. The specific application is as follows:

1. Commercial concrete, high-strength concrete, self-leveling concrete, unshaped refractory, dry-mixed (premixed) mortar, high-strength non-shrinkage grout, wear-resistant industrial floor, repair mortar, polymer mortar, thermal insulation mortar, anti-resistance Seepage, compacting agent, antimony preservative, cement-based polymer waterproofing agent; reinforcement of rubber, plastic, unsaturated polyester, paint, coating and other polymer materials, modification of ceramic products, etc.

2. In the material industry:
(1) High-grade high-performance low-cement refractory castables and prefabricated parts, the service life is three times that of ordinary castables, the refractoriness is improved by about 100 °C, and the high temperature strength and thermal shock resistance are obviously improved. It has been widely used in: coke oven, iron making, steel making, steel rolling, non-ferrous metals, glass, ceramics and power generation.
(2) Large iron trenches and steel-clad materials, permeable bricks, smear repair materials, etc.
(3) Self-flowing refractory casting materials and dry-wet spray application.
(4) Oxide-bonded silicon carbide products (ceramic kiln furniture, flame barriers, etc.).
(5) High-temperature type calcium silicate lightweight insulation material.
(6) The electric porcelain kiln is driven by corundum mullite.
(7) High temperature wear resistant materials and products.
(8) Corundum and ceramic products.
(9) Sailong combined products.
At present, in addition to being commonly used in cast refractories, a large number of applications are also found in fused and sintered refractories.

3. New wall materials and facing materials:
(1) Polymer mortar, thermal insulation mortar and interface agent for wall insulation.
(2) Cement-based polymer waterproof material.
(3) Lightweight aggregate insulation and energy saving products and products.
(4) The inner and outer wall construction is processed with putty powder.

4. Other uses:
(1) Silicate brick raw materials.
(2) Production of water glass.
(3) Used as a reinforcing material for organic compounds. Because its composition is similar to that produced by gas phase method. It can be used as a filler reinforcing material in polymer materials such as rubber, resin, paint, paint, and unsaturated polyester.
(4) Used as an anti-caking agent in the fertilizer industry.
