1. What is carbon black?
Carbon black is also called carbon black, which is invisible carbon. It is characterized by fine, light, loose, black powder with a range of 10-3000m2/g and a large specific surface area. The production process is that the raw materials (coal tar, ethylene tar, etc.) are pyrolyzed or not in the state of insufficient air. It is completely burned to make carbon black.
The specific gravity of carbon black products is 1.8-2.1, and there are three types in terms of raw materials: oil is called "lamp black", natural gas is called "gas black", and acetylene is called "acetylene black". From the perspective of production methods, it can also be divided into "groove black", "furnace black" and so on.
2. What is the composition of carbon black?
The composition of carbon black is mainly carbon, element C, and the carbon content in the composition of carbon black is usually >98%, with less water and ash, and the national standard for water content is <4%.
However, when domestic manufacturers produce carbon black, they generally control it at <1.5%, and the ash content is within the range of <0.5%.
3. What are the characteristics of carbon black?
Friends who want to know what carbon black is, can you first understand the characteristics of carbon black?
Carbon black features: reinforcement, coloring, conductivity, wear resistance, increased stretchability, insoluble in water.
4. What are the uses of carbon black?
Due to its excellent performance, carbon black products can be used in the tire industry, as dyes such as ink, and in the rubber industry.
