Let me talk aboutSuperfine silica powderAs a rubber reinforcement material, there are the following forms:

Pink quartz. It is mainly made of natural diatomaceous earth as raw material, after pulverization, high temperature calcination, and removal of organic impurities. It can be used in rubber to make the rubber firm, reduce the density of the rubber, and increase the thermal insulation performance. It is suitable for the manufacture of insulating rubber and model products. And foam products, used for hard rubber can increase the softening temperature.

Silica fume. The silicon dioxide content is 75%～79%, natural minerals are mined, dried, crushed and sieved. It can be used for hoses, tapes and other rubber products. It has good dispersibility and can be filled in a high amount. The surface of the calendered products is smooth. It is equivalent to light calcium; adhesion strength and tear deformation are better than clay, wear resistance and elasticity are better than clay and light calcium; good aging performance, the price is lower than clay and light calcium.

Quartz powder. Quartz powder has different types such as amorphous and microcrystalline, which are processed by crushing natural minerals.

In terms of specific applications, powder quartz is added to replace pottery clay and light calcium carbonate in the battery shell, and the filling amount is increased from 55% to 65%, and the process performance is excellent, no powder spraying and flying phenomenon, and good vulcanization performance. Physical and mechanical properties such as acid resistance, voltage resistance, thermal deformation and falling ball impact of the prepared battery rubber case can meet the requirements, and the rubber case is smooth and smooth, and the yield is improved.

The above are the several forms of superfine silica powder used as rubber reinforcement materials that the editor told you? You can simply understand it. The content is for your reference, you can contact us if you need to consult.
