Carbon blacks are fine pigment particles that consist mainly of carbon. Its production became popular in the second century with the establishment of paper production. Hydrocarbons such as oil and natural gas are the basic raw materials for manufacturing them. However, the properties of carbon black differ depending on the processes carried out with the use of carbon machinery and production technology.

Manufacturing carbon black in a carbon black making machine

Producers of traditional carbon black use one of two manufacturing processes. These are either the oil furnace process or thermal process. For the oil furnace process, they heat and continuously inject aromatic liquid oil into the gas-fired furnace. They cool the carbon particles by passing them through heat exchangers and direct water sprays and filter them using a fabric filter. Finally, they use a carbon black pellet machine to convert the recovered carbon into marketable pellets for tire, rubber, and plastic products. Carbon pelletization is important because it increases its density and thermal stability, making it safe for storage and packaging.

The thermal process is cyclical and involves the use of two furnaces to decompose natural gas. When the first furnace black produces carbon and hydrogen, you cool it. Then, use the second one while you heat the first one.

Environmental impact of carbon black

The production of carbon black through the combustion of fossil fuels generates emissions associated with many negative effects both on humans and the environment. It has been linked to congenital disabilities, cancer, respiratory and cardiovascular diseases. Its ability to affect rain and cloud patterns makes it a key contributor to climate change. For this reason, silica is overtaking in terms of popularity due to the fact that it is a natural materials found in the earths crust. A solution to reducing carbon blacks impact on the environment is to produce it by using abandoned tires as the feedstock in the carbon black machine.

This is a safer, environment-friendly substitute because the manufacturing process removes carbon dioxide from the environment and reduces air pollution.

Green alternative to carbon black

The hazardous impact of carbon black on both human and environmental health has led to a rise in the demand for green alternatives like recovered carbon black. Its manufacturing process, which is the pyrolysis of waste tires during recycling, is eco-friendly. It differs from traditional carbon black production methods, which involve burning petroleum products.

Using and recycling abandoned tires is economical and safer for the environment because it is cheap and reduces the emission of carbon dioxide. In addition, recovered carbon black possesses a great ability to strengthen mechanical rubber products due to its low ash content. This characteristic makes it a better and less polluting substitute.
