Carbon Black These pigments are obtained from gases and petroleum liquids, which are classified into channel or furnace soot, depending on the type of production method. For more information about Carbon black wholesale price in 2021, visit our site.
How is carbon black obtained?
The basis of this method is incomplete combustion of hydrocarbon gases in special chambers designed for this purpose. Smoke from incomplete combustion of hydrocarbon gases passes through iron channels. The soot particles in the incomplete combustion smoke settle on the channel wall and are then separated from the channel wall by mechanical lathes. The obtained soot is passed through very fine cloth nets so that if any gravel is separated from the canal wall and is accompanied by soot, it is removed. The quality of soot can be controlled by the shape of the flame, the distance of the soot from the channel surface, the amount of air and the quality of the gas consumed. The soot thus obtained is soft and fluffy due to the air and gaseous by-products of incomplete combustion trapped inside its particles. Therefore, it must be pressed to trap air and gases.
To be taken out of it, or by dry and wet methods to form it into pellet particles. The efficiency of the duct process is very low and it is very difficult to prevent smoke and combustion gas from entering the air atmosphere. Due to these reasons and considering the fact that in the kiln process, no significant improvements have been made to the channel method, kiln soot is being replaced by channel soot in several cases. Gas soot process The basis of this method is similar to the channel method, but they differ in two ways: A. The soot from incomplete combustion of the petroleum product is directed into the cooled cylinders and after the soot particles sit on the wall of the cylinders, they are separated by mechanical lathes.
B- In this method, oil is used instead of hydrocarbon gases. This makes the gas soot method more flexible than the channel method. The next operation for soot preparation is like the channel method operation. Furnace process Older types of furnace soot were made from incomplete combustion of gases inside refractory furnaces. In these furnaces, only a large burner was installed, and the iodine and action products containing soot were quickly cooled with water and then sent into bag filters or electrical precipitators. The soot thus obtained was used only in the rubber industry. Newer methods use the same type of furnace, but instead of gas, they burn oil (although they sometimes use a mixture of the two) and provide a wide range of soot types by changing operating conditions. In addition to the rubber industry, they are also used in dyeing and manufacturing printing inks. Currently, most soot is produced by the kiln method.

Oxidized soot on the surface of their particles is the result of carboxyl groups and other groups that improve some properties of soot. These improvements are especially noticeable in the fluidity and fluidity and ease of soot spreading. In other methods of soot production, thermal decomposition is used instead of incomplete combustion. These methods include thermal decomposition, arc decomposition, and acetylene smoke, but in all of these methods the operating efficiency is very low compared to furnace and duct methods.
