Carbon black is one of the indispensable materials in the production of rubber conveyor belts. Its main function is to use as a reinforcing agent to improve the strength of rubber conveyor belts. The following Zhongqin conveyor belt manufacturers will take a detailed understanding of the application of carbon black in the production of rubber conveyor belts.
Carbon black is formed by the aggregation of spherical or chain particles with an average diameter of 5 to 30 nm. The inside contains a microcrystalline structure with a diameter of 3 to 500 nm, which can react with various radicals. The specific gravity of carbon black is 1.8 to 1.9, the specific gravity of granular carbon black is 0.35 to 0.4, and the specific gravity of powdered carbon black is 0.04 to 0.08.
Carbon black is not only very dark in color but also extremely strong in coating power. It is an ideal black pigment. According to a survey by the US market research firm Freedonia, 67% of the world's carbon black is used to make tires, 24% for rubber tubes, conveyor belts and other rubber products, and the remaining 9% for inks. Dyes, paints and other products.
As a very important reinforcing agent in the rubber industry, carbon black can not only improve the strength of rubber products, but also improve the process performance of the rubber compound, giving the products a variety of properties such as abrasion resistance, tear resistance, heat resistance, etc. Service life. It plays a vital role in improving tire tread wear and rolling resistance. The reason why the reinforcing agent can improve the hardness and mechanical strength of the rubber product is because the surface of the reinforcing agent particles is in contact with the rubber macromolecule to produce physical adsorption.
