In the synthesis of silicone rubber, it is necessary to mediate various catalysts and silica white carbon black. The same semi-finished raw materials are indispensable in the process of curing silicon......
2019-11-27Too much plasticizer or structure control agent is added to the rubber compound, resulting in poor rubber resilience and slow vulcanization speed; too much plasticizer or structure control agent is ad......
2019-11-27It is also an important factor that leads to poor rubber resilience and slow vulcanization speed. As the white carbon black itself is acidic, and the added structure control agents are mostly acidic, ......
2019-11-27When the rubber compound does not reach the normal sulfur point during vulcanization, the vulcanization speed is too long, and the vulcanization is insufficient, resulting in poor rubber elasticity. Y......
2019-11-27The waterborne urethane acrylate contains a large amount of reactive groups to impart good flexibility and cohesiveness to the cured film, but at the same time, mechanical properties, solvent resistan......
2019-11-27Silica has a very significant reinforcing effect on various rubbers, among which the reinforcing effect on silicone rubber is particularly outstanding.  ......
2019-11-271. Compounding and dispersing Due to the large specific surface area of white carbon black, it tends to secondary aggregation. In addition, it is very easy to absorb water in the ......
2019-11-27(1) Moisture The moisture content of precipitation silica includes: free water and bound water. Free water on the surface of white carbon black is easily removed under heat. Too l......
2019-11-26The particle size of precipitation method is divided into primary particle size and secondary structure particle size. Generally speaking, the secondary structure of silica is broken during the compou......
2019-11-26Silica has a wide range of uses, and different products have different uses. Used as a good reinforcing agent for synthetic rubbers, its reinforcing performance is second only to carbon black, and eve......
2019-11-26Silica is a synthetic product and is a hydrated silica. White carbon black is similar in appearance and function to carbon black. Therefore it is called white carbon black. It is a white loose powder,......
2019-11-26The purpose of the precipitation method of carbon black for off-road tire tread is to reduce its heat generation, improve its heat resistance and its ability to resist chipping. According to reports, ......
2019-11-261, alcohol and alcohol amine active agents Adjuvants such as alcohols and alcohol amines, such as polyethylene glycol (PEG) and triethanolamine, are first adsorbed by white carbon black during rubber......
2019-11-261. The storage of white carbon black absorbs moisture in the air, and makes its structure stable, that is, moisture absorption. 2. When the white carbon black rubber compound is mixed, it is easy t......
2019-11-26Silica used in truck tires to improve the puncture resistance and tear resistance of the tread. Precipitation method is particularly suitable for its tread because it not only reduces rolling res......
