What is Acetylene Black?
Acetylene black is a type of carbon black. It is obtained from acetylene thermal decomposition process. This type of carbon black is highly purified, and it is also an extremely conductive material. Therefore, it is very important in the production of dry cells, electric power cables, silicon products, etc. We can use acetylene black as a substitute for carbon black.
What is Carbon Black?
Carbon black is an inorganic compound that forms from the incomplete combustion of heavy petroleum products. It is an adsorbing agent. There are a few subtypes of carbon black such as acetylene black, channel black, furnace black, lamp black, and thermal black. The heavy petroleum products are useful sources for the production of this material. For example, FCC tar, coal tar, ethylene cracking tar, etc. However, this material should not be confused with soot.
Carbon black contains only carbon atoms, and this material appears as a black powder. Practically, this powder does not dissolve in water. Since there are only carbon atoms in this compound, the molar mass of carbon black is 12 g/mol. All types of carbon black contain chemisorbed oxygen complexes. E.g. carboxylic, quinonic, lactonic, etc. We can observe these complexes on the surface of carbon black particles. Based on the reaction conditions and manufacturing steps, the degree of these complexes on particle surface differs. These surface complexes are mostly volatile species. Besides, carbon black is a non-conductive material due to its volatile content.
There are many important applications of carbon black. For example, it is important as a reinforcing material. It is useful as a reinforcing filler for tires and other rubber products. In addition to that, it is important as a colour pigment in paint, plastics, ink, etc. The carbon black that has a vegetable origin are mainly used as food colouring agents.
乙炔黑色和碳黑色有什么区别?
碳黑是重要的吸附剂。乙炔黑是一种碳黑色,与其他类型的碳黑色材料不同,具体取决于生产源。顾名思义,乙炔黑是乙炔的来源,而炭黑的来源是重石油产品。因此,乙炔黑色和碳黑色之间的关键差异是乙炔黑是从乙炔的热分解中获得的,而碳黑是由于重石油化合物的不完全燃烧而产生的。但是,我们可以使用乙炔黑作为碳黑色的替代品。

I just wanted to say thanks for this! I saw carbon black on TV and was intrigued by it and went to go look it up and came to here.
再次感谢您做到这一点,我学到了很多!
