What are the effects of different production processes on the quality of Conductive carbon black?
Publish Time: 2024-08-20
Conductive carbon black plays an important role in many fields, and the difference in its production process will have a significant impact on the quality.
First, the furnace process is one of the common methods for producing Conductive carbon black. The Conductive carbon black produced by this process has a higher structure and a larger specific surface area. The higher structure enables the carbon black particles to form a good conductive network, thereby improving the conductive performance. At the same time, the larger specific surface area is also conducive to the combination with other materials and enhances the conductive effect of the composite material. However, if the parameters of the furnace process are not properly controlled, it may cause uneven particle size distribution of carbon black, affecting its dispersion and stability in the application.
Secondly, the Conductive carbon black produced by the slot process usually has a more regular particle shape and a higher purity. The regular particle shape is conducive to forming a uniform conductive channel in the material and improving the uniformity of conductivity. High purity reduces the interference of impurities on the conductive performance. However, the production efficiency of the slot process is relatively low and the cost is high.
In addition, the thermal cracking method is also a process for producing Conductive carbon black. The carbon black produced by this process has a lower oxygen content and a higher degree of crystallinity. Low oxygen content can reduce the resistance of carbon black and improve its conductivity. High crystallinity makes carbon black have better thermal and chemical stability. However, the thermal cracking method has high requirements on equipment and the process is relatively complicated.
In short, different production processes will give Conductive carbon black different quality characteristics. When choosing Conductive carbon black, it is necessary to comprehensively consider the conductivity, dispersibility, stability and other factors of carbon black produced by various processes according to specific application requirements. At the same time, manufacturers should also continuously optimize the production process and improve the quality of Conductive carbon black to meet the market demand for high-performance conductive materials.
