Use Of New Kaolin In Rubber Soles

Application of new kaolin in rubber shoe sole compound.

The results showed that compared with uncalcined kaolin, the binding water content of calcined kaolin at low temperature decreased, the content of silica and three alumina increased, the activity point increased, the structure changed, and the particle size was smaller and even. Compared with the uncalcined kaolin filled NR compound, the vulcanization characteristic curves of low-temperature calcined kaolin filled NR compound were basically the same. The hardness of Shaoer A was unchanged and tensile strength increased. Both of them reached the requirements of the industry standard for the non pparent footwear sole of sports shoes.

Recently, ceramics, rubber, plastic, artificial leather, cement, refractory materials, chemical industry and agriculture have not been widely used. With the further improvement of the processing technology of kaolinite, the application scope of kaolin will be more and more extensive.

Kaolin is a non-metallic mineral widely existed in nature. In the past, it was generally used to produce ceramics, fire-resistant materials, and a small amount of filler in plastic and rubber. With the development of various fields in the national economy, people pay more and more attention to the deep processing of high fly ash, because it can not only acquire new materials with special properties, but also increase economic benefits. One of the ways of deep processing of kaolin is to further heat, roast and dehydrate kaolin by washing and toughening.

Commonly used rubber filler for footwear is mainly organic filler and inorganic filler two kinds, the former includes reclaimed rubber and recycling materials, the latter includes white carbon black, calcium carbonate, titanium dioxide, magnesium carbonate, Magnesium Oxide, carbon black and zinc oxide powder.

Kaolin is a new type of filler for rubber products developed in recent years.

However, all applications of kaolin must be processed into fine powder before they can be added to other materials and fully integrated.

The products of Victor heavy mill include: Raymond mill, high speed medium speed mill, three ring medium speed powder mill, through centrifugal mill, high pressure flour mill, etc., which are suitable for kaolin, barite, calcite, potassium feldspar, talc, marble, limestone, pottery and porcelain. The Mori hardness is not greater than 7, and the humidity is less than 6% in the non inflammable and explosive mining, chemical, building materials, metallurgy and other industries. The processing technology of 280 kinds of materials is easy.
