In fact, there are many kinds of carbon black, and there are good and bad points. It can be divided into ordinary carbon black and pigment carbon black. Pigment carbon black is mainly used in some products that require high product quality, while ordinary carbon black does not need So strict, the following editor will briefly introduce the difference between ordinary carbon black and pigment carbon black.
What is carbon black?
Carbon black (also known as carbon black) is a quasi-graphite structure substance formed by incomplete combustion or thermal cracking of hydrocarbon compounds (mainly petroleum derivatives). It exists in the form of aggregates, and the surface is in the form of pure black powder or granules. According to the original particle size, structure and surface activity vary with raw materials and production processes. Carbon black is insoluble in water, can be divided into acid and alkali, and produces carbon dioxide after combustion. The main component of carbon black is carbon, and it also contains trace amounts of hydrogen, oxygen, sulfur, ash, tar and water.
According to the performance of carbon black, there are "reinforcing carbon black", "conductive carbon black", "wear-resistant carbon black" and so on. Carbon black can be used as a black dye for the manufacture of Chinese inks, inks, paints, etc., and is also commonly used as a reinforcing agent for rubber production; carbon black is usually divided into pigment carbon black, rubber carbon black, conductive carbon black and special carbon black.
What is Pigment Carbon Black?
Carbon black used in coatings, inks, and plastics is called pigmented carbon black, or pigment black. Pigment carbon black is used in coatings, inks, plastics, as well as conductive, antistatic, UV shielding and resin aging prevention. Therefore, carbon black used in rubber is broadly called specialty carbon black.
What is the difference between ordinary carbon black and pigment carbon black?
Ordinary carbon black is mainly used in the rubber industry, with large demand, low price and simple production process.
Pigment carbon black is widely used, the demand is relatively small, but the price is high, the production process is cumbersome, and the production requirements of different industries are not understood.
