The active silicon micropowder (treated by a coupling agent) is filled in a rubber such as natural rubber or butadiene rubber, and the powder is easily dispersed (see the reason for dispersing the ultrafine powder), the mixing process performance is good, and the rolling and extruding properties are good. And can improve the vulcanization speed of the vulcanized rubber, and also improve the viscosity of the rubber, especially the ultra-fine silicon micropowder, replacing some of the white carbon black in the rubber compound, which is very good for improving the physical properties of the product and reducing the production cost. Good effect. Silicon micropowders with a particle content of less than 2 um of 60-70% are excellent for export-grade medicinal chlorinated butyl rubber stoppers and for use in electrical insulating rubber shoes.

Silicon micropowder is used as a filler in the production of imitation leather. Its technical strength, elongation and flexibility are superior to those of inorganic materials such as light calcium carbonate, activated calcium carbonate and active pyrophyllite. product.

The silicon micropowder replaces the refined clay, light carbonic acid and other powder materials for the battery shell, and the filling amount is up to about 65%, and the process performance is good. The obtained rubber shell products have smooth and flat appearance, high hardness, acid corrosion resistance, voltage resistance, thermal deformation and impact resistance and other physical and mechanical properties all meet or exceed JB3076-82 technical indicators.
