Application of Molten Silicon Micropowder in Six Major Industries (Part 1)

1、 Application of Silicon Micropowder in Rubber Products

Activated silica micro powder (treated with coupling agent) is filled into natural rubber, butadiene rubber and other rubber materials. The powder is easy to disperse, has good mixing process performance, good rolling and extrusion properties, and can improve the vulcanization speed of vulcanized rubber. It also has the effect of enhancing the viscosity of rubber, especially ultrafine silica micro powder, which replaces some white carbon black in the rubber material. It can improve the physical properties of the product and reduce the production of rubber

Both production costs have a good effect- 2 μ m of 60-70% silicon micro powder is used for export grade medicinal chlorinated butyl rubber bottle stoppers and has excellent effects in electrical insulation rubber shoes.

Silicon micro powder is used as a filler in the production of imitation leather, and its technical indicators such as strength, elongation, and flexibility are superior to those of products made with inorganic materials such as lightweight calcium carbonate, active calcium carbonate, and active pyrophyllite as fillers.

Silicon micro powder is used to replace refined clay, lightweight carbonate and other powder materials in battery shells, with a filling capacity of about 65% and good process performance. The obtained rubber shell products have a smooth and flat appearance, high hardness, acid corrosion resistance, voltage resistance, thermal deformation resistance, and impact resistance, among other physical and mechanical properties, all of which meet or exceed the technical specifications of JB3076-82.

2、 Application of Silicon Micropowder in Plastic Products

Activated silica micro powder is an ideal reinforcing agent for products such as polypropylene, polyvinyl chloride, and polyethylene. It not only has a large filling amount, but also has good tensile strength. Made into masterbatch for use in PVC floor tiles, it can improve the wear resistance of the product.

Silicon micro powder is applied to olefin resin films, with uniform powder dispersion, good film-forming properties, and strong mechanical properties. Compared with plastic films produced using PCC as a filler, it reduces the infrared transmittance by more than 10% and is widely promoted for agricultural greenhouse film applications throughout the country. It can also be used in fields such as wire and cable sheaths.

3、 Application of Silicon Micropowder in Melting Instrument Glass and Fiberglass

Due to the small particle size and high purity of silicon micro powder, it is easy to melt and has a short time in glass production. The physical and chemical properties and appearance quality of products such as borosilicate instrument glass, sodium instrument glass, neutral vessels, etc. meet the corresponding standards. At the same time, the energy-saving effect is particularly significant in production.

Furthermore, based on the characteristics of fine and uniform particle size and large specific surface area of silicon micro powder, it is used in the new process of direct drawing of glass fibers, greatly improving the homogenization degree of glass fiber composites and accelerating the vitrification speed in the furnace. The stability of wire drawing is better than that of glass ball wire drawing process, and it has significant energy-saving and cost reducing effects. As an energy-saving mineral raw material, silicon micro powder is applied to ceramics

In the industry, it has also achieved ideal results in reducing firing temperature and improving yield.
