Carbon black influence on the conveyor belt process-2

Mar 09, 2019

Nylon conveyor belt with the effect of carbon black on the mixing and feeding and dispersion: the finer the particle size of carbon black, the more difficult it is to mix, the slower the material consumption, the higher the energy consumption, the higher the heat generation and the more difficult the dispersion. Because the particle size is small, the specific surface area is large, and the area to be wetted is large, the influence of the carbon black structure on the dispersion is also obvious. The high structure is slower than the low structure, but the dispersion is fast because the structure is high, and the volume of the voids Larger, it takes more time to exclude the air, and once eaten, the carbon black with high structure is easy to disperse;

The effect of carbon black on the technical performance of the heat-vulcanized rubber in the conveyor belt: the carbon black particle size plays a decisive role in the tensile strength, tear strength and wear resistance of the vulcanized rubber. The particle size is small, the tear strength is determined. The tensile stress and hardness are increased, while the elasticity and elongation are decreased, and the change of the compression set is small because the particle size is small, the specific surface area is large, and the boundary area between the rubber and the carbon black is large, and the interaction between the two is generated. Combined with rubber;
