what is the difference between "carbon black + tires" and "white carbon black + tires"?

Author : Clirik

 In recent years, the growth in demand for green tires and silicone rubber, as well as the increasing capacity of tire manufacturers, have brought continued growth in demand for white carbon black. With the advent of the green tire era, the market demand for highly dispersed white carbon black will show leapfrog growth. Some developed countries have begun to encourage the use of silica instead of carbon black in the production of tires and rubber products. So, what is the difference between "carbon black + tires" and "white carbon black + tires"?
Carbon black and white carbon black
Carbon black, also known as carbon black, is an amorphous carbon. Light, loose and very fine black powder with a very large surface area ranging from 10 to 3000 m2/g. It is a product of carbonaceous matter (coal, natural gas, heavy oil, fuel oil, etc.) which is incompletely burned or decomposed by heat under conditions of insufficient air.
White carbon black is a general term for white powdered X-ray amorphous silicic acid and silicate products. It mainly refers to precipitated silica, fumed silica, ultrafine silica gel and aerogel, and also includes powder, synthesis of aluminum silicate and calcium silicate. White carbon black is a porous substance whose composition can be represented by SiO2•nH2O, wherein nH2O is in the form of a surface hydroxyl group. It is soluble in caustic and hydrofluoric acid and insoluble in water, solvents and acids (except hydrofluoric acid). High temperature resistance, non-combustible, odorless, odorless, and has good electrical insulation.
As a filler, white carbon has less interaction between particles and less energy loss. The particles of carbon black have more friction and energy loss. Therefore, rubber tires using white carbon as a filler have less loss.
The friction between the white carbon black aggregates is small, the energy loss is reduced, and the rolling resistance is reduced; the restraint applied by the white carbon black is small, the rubber can move freely, the rubber elasticity is large, and the deformation of the road surface is easily absorbed, and it is easy to dissolve between the road surface and the road surface. Rubber, showing high grip. For carbon black, the aggregates are large and the friction is large, and the rubber has a greater constraint on the carbon black.
Our company can offer you with the ultra fine carbon black powder making machine.

Carbon black powder making machine
HGM80 ultra fine carbon black powder making machine is an ultra-fine powder equipment introduced by our company. It is mainly applied to carbon black, limestone, calcite, calcium carbonate and other materials in industrial applications. The fineness of processing is mainly high fineness. In general, the processing fineness of our customers is more than 800 mesh, such as extensive processing to 1250 mesh, 2500 mesh and other fineness. The mineral powder processed by this model has high powder yield, high pass rate, and for equipment. The wear is relatively small, so it has won unanimous recognition from domestic and foreign customers. Especially in the processing of carbon black micro-powder, our company hgm series ultra-fine grinding machine is the only one in China that has obtained the technology of non-polluting carbon black production equipment, and adopted the negative pressure design in the processing of carbon black. The entire production line equipment is in a negative pressure environment, no dust is generated, the production process is environmentally friendly, and it is not polluted. Especially in the world's general policy of improving environmental protection requirements, the redesigned equipment is very suitable to meet customer needs.
