2019-07-03At present, the main method for preparing white carbon black is chemical vapor deposition (CAV), which is also called pyrolysis, dry or combustion. The raw materials are generally silicon tetrachlorid......
2019-07-03China's white carbon black production process has been relatively backward, with a single product specification. In recent years, the situation has improved and the process technology has made breakth......
2019-07-031. Application Silica has been produced since 1948 and used as a filler in the rubber industry. By the 1980s, about 67% of the world's precipitated silica was used in the rubber industry, of which 45......
2019-07-031. Tire White carbon black was originally used only in white tire side car tire decorative strips, and its use has gradually expanded and is now used in various tire parts. Such as tread rubber, BIIR......
2019-07-03(1) The fumed silica is surface-treated with methacryl silane and then added to a polyurethane coating to provide a friction-resistant effect. (2) Fumed silica can also improve the weather resistance......
2019-07-03Fumed silica has significant light scattering ability due to its small particle size and network structure. Therefore, fumed silica has good optical properties in varnishes and is the first choice for......
2019-07-03In the powder coating system, due to the small particle size and high surface energy of fumed silica, it can be adsorbed on the surface of the coating powder and form a surface layer on the surface of......
2019-07-03The fumed silica has a small particle size, a large specific surface area, and a silanol group on the surface. These silanol groups can interact with adjacent fumed silica particles to form hydrogen b......
2019-07-03The surface of the fumed silica has a large amount of hydroxyl groups which form hydrogen bonds between the aggregates, and when sufficiently dispersed in the coating, a network of silica is formed. ......
2019-07-03Rheology additive Rheology is an important property of coatings. It directly affects the appearance, performance and storage stability of coatings. Different coating systems have different requiremen......
2019-07-01“Reducing coal consumption and promoting low-carbon life” are also “tan”. Why is there a difference between “carbon” and “char”? Why do you sometimes have "carbon materials" and sometimes "carbon mate......
2019-07-01The book "Environment, Health and Negative Oxygen Ion" edited by Chinese Academy of Sciences experts, Tsinghua University Ph.D. and Professor Lin Jinming has repeatedly said that when the concentratio......
2019-07-01There are many preparation methods for white carbon black. Most domestic manufacturers mainly use precipitation method, which mainly uses water glass as raw material. Even gas phase white carbon black......
