Superfine silica powderIn modern polymer materials such as plastics, rubber, coatings, etc., non-metallic mineral fillers occupy a very important position. Adding non-metallic mineral fillers to the polymer base can not only reduce the cost of polymer materials, but more importantly, improve the function and dimensional stability of the materials, and give the materials some special physical and chemical functions, such as compression resistance. , Impact resistance, corrosion resistance, flame retardancy, insulation, etc.

Natural quartz stone, quartz sand and powdered quartz are important industrial mineral materials, which are widely used in glass, casting, construction materials, ceramics, chemicals, metallurgy, refractory materials, abrasives, fillers and other categories. Silicon micropowder processed from quartz sand and its tailings, powdered quartz, etc., as a filler for polymer materials such as plastics, rubber, coatings, etc., has become more and more popular in terms of ultrafine destruction, purification, modification and use. Attention. In recent years, with the continuous advancement of ultrafine destruction technology, ultrafine, ultrapure, and modified non-metallic mineral fillers have become more and more widely used.

Pink quartz. It is mainly made of natural diatomaceous earth, which is destroyed, high-temperature calcination, and organic impurities are removed. It can be used in rubber to make the rubber hard, reduce the density of the rubber, and add heat insulation. It is suitable for making insulating rubber and models. Products and foam products, used in hard rubber can increase the softening temperature.

Silica fume. The silicon dioxide content is 75%～79%. It is made from natural mineral deposits after mining, drying, destruction and screening. 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 its calendered products is lubricated. Appropriate with light calcium; adhesion strength and tear deformation are better than clay, abrasion resistance and elasticity are better than clay and light calcium; good aging function, 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 the destruction of natural mineral deposits.

In terms of detailed use, powder quartz is added to replace pottery clay and light calcium carbonate in the battery shell. The filling amount is added from 55% to 65%, and the process function, no powder spraying and flying phenomenon, and good vulcanization function. The physical and mechanical functions such as acid resistance, voltage resistance, thermal deformation and falling ball impact of the prepared battery plastic shell can meet the requirements, and the surface of the plastic shell is flat and lubricated, and the yield is improved.
