What are the raw materials for making carbon black?
The raw materials for making carbon black include petroleum products, pitch coal tar, N oil, natural gas and other raw materials with extremely high carbon content.
What is the production principle of carbon black?
The production principle of carbon black is that carbon black raw materials cannot be produced under conditions of subatmospheric pressure and insufficient air, but are formed by incomplete combustion or pyrolysis of hydrocarbons at high temperatures.
What are the production processes of carbon black?
The production processes of carbon black include furnace method, spray method, lamp smoke method, tank method, roller method, mixed gas method, thermal cracking method, acetylene method and plasma method. Among them, the furnace method, spray method, lamp smoke method, groove method, drum method, and mixed gas method are incomplete combustion methods, and the thermal cracking method, acetylene method and plasma method are thermal cracking methods.
What raw materials are used for different carbon black processes?
First of all, everyone must understand that the carbon black products produced by different carbon black production processes are different. Of course, the raw materials used are also different. Let me show you what raw materials are used for different carbon black processes.
What raw material is lamp smoke carbon black made of?
Lamp smoke method carbon black is burned on a flat burning iron plate with a diameter of up to 1.5m by using carbon black raw materials. 1/4) and the fire pipe reach the deposition device, and finally collect the carbon black.
What raw material is gas-process carbon black made of?
Gas-process carbon black uses raw material hydrocarbons, which are first gasified when heated with raw material hydrocarbons, and then carried into the burner by spontaneously combustible gas (supplied with energy) as a carrier. generated in flames. As each flame is small and burns in air, carbon black is formed.
What raw material is channel black made of?
Channel carbon black uses natural gas as raw material. The process of channel black is similar to the gas combustion process of gas black production process. Natural gas burns and emits many fan-shaped flames. The obtained product is similar to gas black, but the difference is that the flat carbon black is used here The water-cooled U-shaped tank is used as a deposition tank for carbon black.
What raw material is Furnace Carbon Black made of?
Furnace carbon black uses oil as raw material. The production process is carried out in a closed furnace under anaerobic conditions. A large flame is used, oil is used as raw material, and combustible gas is added to make it reach the required level in the furnace. temperature.
The role and use of carbon black
There are still many functions of carbon black, for example, it mainly plays the role of reinforcing agent and filler in rubber, it mainly plays the role of coloring in ink and coating, and it is used as ultraviolet light shielding agent in plastic products. It is also an important additive in many other products, such as electrodes, dry batteries, resistors, explosives, cosmetics and polishing pastes. The main role played in different industries is different.
The above is what raw materials are used to make carbon black in different processes provided by the editor of Carbon Black Industry Network. It can be seen that the raw materials required for different carbon black processes are different. After reading it, I believe everyone will know what carbon black is. Learn more.
