As a replacement product of traditional pneumatic tires, solid forklift tires are widely used in mines, factories, ports, warehouses and other places with slow speed and high load.

Because the road conditions in these occasions are relatively harsh, the requirements for tire performance are relatively high. At present, solid tires are mostly rubber tires. In order to obtain better performance of rubber tires, a large amount of carbon black is used for reinforcement.

Carbon black is mainly used in tire products in the rubber industry. The carbon black used in the tire industry accounts for more than 80% of the carbon black required by the entire rubber industry. The carbon black used in rubber products other than tires accounts for about 20% of the total amount of carbon black used.

According to the carbon black reinforcement theory, the reinforcement of carbon black to rubber mainly depends on the three elements of carbon black particle size, structure degree, and surface activity. It should be emphasized that if carbon black is not uniformly dispersed in rubber, it cannot play its reinforcing effect. Therefore, the dispersibility of carbon black in rubber and its distribution state and structure after dispersion are directly related to the vulcanized rubber Physical and mechanical properties. Obviously, if one type of carbon black is mixed with different types of carbon black, the dispersion process and distribution state will be very different.

Carbon black is an important reinforcing filler, which has an important impact on the physical and mechanical properties and processing technology of rubber compounds. However, the impact on the properties of rubber materials such as heat resistance, oil resistance, and corrosion resistance is far less than that of the rubber material itself. The vulcanization process is straightforward. It is for this reason that the general rubber formulators are not very clear about the specific performance indicators of a certain type of carbon black, and they often only pay attention to the selection of a certain type of carbon black, and do not examine the specific indicators of the use of carbon black in detail. Varieties of carbon black, this must be corrected.
