The purpose of dispersing pigment carbon black is to make it uniformly distributed in the carrier. The difference in distribution will directly affect the hue, blackness and hiding power of the product.
In the application of organic/carbon black pigments, unstable color intensity, poor carbon blackness and color, uneven pigment distribution and even clogging of the filter screen often occur. These problems are actually caused by poor dispersion.
The problem of carbon black dispersion in rubber products means that the carbon black added during rubber mixing is unevenly dispersed in the rubber, resulting in a decrease in the performance of the rubber products.
Particle size
The particle size of carbon black represents the original particle size of carbon black. It is tested by an electron microscope and is the average value of a certain number of particle sizes.
What is carbon black?
Carbon black (also called carbon black) is a colloidal particle similar to a sphere formed by incomplete combustion or thermal cracking of hydrocarbon compounds (liquid or gaseous). It exists in the form of aggregates and appears as pure black powder or granular. The particle size, structure and surface activity of products vary greatly depending on raw materials, manufacturing methods and production processes. The main component of carbon black is carbon, and also contains trace amounts of hydrogen, oxygen, ash and moisture.
Carbon black applications As an indispensable chemical raw material, carbon black has properties such as reinforcement, coloring, conductivity, light resistance, chemical resistance, and high temperature resistance. It is widely used in automobile tires, inks, coatings, batteries and other raw materials. …
