Carbon black is a general term for industrial products and has many varieties in different fields. According to the different properties of carbon black, it is widely used in various industries. Its main component is carbon, and it contains a small amount of oxygen, hydrogen, sulfur, etc. According to the production process, there are tank method, furnace method, cracking method, etc., and according to the raw materials, there are carbon black, gas black, etc. According to the application, it can also be divided into conductive carbon black, pigment carbon black, colorant carbon black, etc. If you want to learn more, please continue to explore with the editor.
Conductive carbon black is mainly used as a reinforcing and filling agent for rubber, and its consumption is about half of the consumption of rubber. Carbon black accounts for 94% of the total amount of rubber, and about 60% of it is used to manufacture tires. These products give rubber particles high tensile strength and tear resistance, and are usually used in the tire industry, rubber seals, shock absorber parts, etc. Rubber products can be used to reinforce and fill with a certain amount of carbon black to improve the performance of rubber products.
Pigment carbon black is mainly used as a coloring agent for inks, paints and plastics, as well as a UV protectant for plastic products. Its particle size and structure are different, and their dispersibility is completely different. The finer the particle size, the more contact surface, and the stronger the cohesion between them.
It can be seen that the carbon black used in water-based coatings with good dispersibility must have a larger particle size and higher structure. If black plastic products are to be used, low-carbon black with smaller particle size should be selected. In order to obtain satisfactory coloring effect, special attention should be paid to the dispersibility of carbon black pigments. Solving the dispersibility of carbon black pigments can only obtain good coloring power.
