Black cat wear-resistant carbon black
Carbon black generally refers to carbon elemental particles, which are generally due to insufficient combustion of organic matter, in which hydrogen and oxygen are converted into water, and carbon is not sufficiently burned to break away from molecules and form carbon black. Carbon black in almost all particle size ranges can be obtained by the furnace black production process, and the carbon black of the same variety does not have the same particle size, and exhibits a particle size distribution range. In general, the finer particles have a narrower particle size distribution. The finer the pigment black, the more contact points between the carbon black aggregates, and the stronger the cohesive force between them, the more work is done on the dispersion when the pigment black is blended into the material, that is, the uniform distribution of the starting carbon black is started. It is large to separate the carbon black particles, and finally achieve the highest blackness and coloration.
The naming system takes into account the vulcanization rate and structure of the carbon black compound and is composed of four systems. The first letter represents the English letter representing the vulcanization rate of the compound. N represents the normal vulcanization rate and S represents the slow vulcanization rate. The first three letters of the letter represent the range of carbon black nitrogen surface area. The second and third numbers are the degree of structure that reacts differently.
N219 black cat wear-resistant carbon black, also known as low structure super wear-resistant furnace black
Compared with n220 carbon black, this product can improve the tensile strength, tear strength and elongation of the rubber compound, and has low sonic heat, high elasticity, and slightly lower tensile stress and wear resistance than n220. This product is used in tire tread rubber to improve its chipping and cracking properties. However, due to its low structure, it is difficult to disperse during mixing. Used in tire tread rubber, especially for off-road tires.
