Production process of tankless gas-mixed carbon black
Gas-mixed carbon black is also called tankless gas-mixed carbon black. Gas-mixed carbon black is produced with mixed oil as raw material and carrier gas of coke oven gas smell. The raw material oil is first preheated, dehydrated and removed of mechanical impurities in the feeding tank and the melting tank in two stages, and then sent to the vaporization tank to be heated and boiled and vaporized. Know why it is called mixed gas carbon black), send it to the fire room for combustion along the raw material main pipe, and send the generated carbon black and the residual gas to the cooling tower for cooling, collect it through the bag filter, remove impurities, and finally enter the dry granulation Machine granulation and packaging.
The main application of gas-mixed carbon black
It is used in large-scale tires and off-road tire tread compounds mainly made of natural rubber or isoprene rubber, and other rubber products that require high elongation properties. It can also be used as coloring inks, paints, and plastics. It is also widely used in aircraft tires, wire and cable insulation layers and sheaths, plastic masterbatches, printing inks, inks and other industries.
What is the performance of gas-mixed carbon black?
The performance of gas-mixed carbon black is mainly manifested in its high degree of surface oxidation, low pH value, high volatile content, good blackness and fluidity. Compounds using aerated carbon blacks have processability similar to natural gas channel blacks and have a delayed effect on vulcanization. The tensile strength and productivity of vulcanized rubber are lower than that of channel black, and the wear resistance is equivalent, but the elongation is slightly higher.
Improvement of production process of gas-mixed carbon black
During the production of gas-mixed carbon black, the vaporization efficiency will be low (such as increasing the load and shortening the production cycle), and relying on the simultaneous operation of multiple sets of equipment to ensure production, resulting in problems such as inability to centralize management and occupying a large amount of labor. With the continuous improvement of gas-mixing process technology and the continuous expansion of production capacity, separate tank vaporization has gradually become an obstacle to the development of gas-mixing carbon black. At this time, it is necessary to improve the production process of gas-mixed carbon black to improve the production efficiency of gas-mixed carbon black. Closed fire room), the change of the temperature distribution of the mixed gas carbon black fire room is improved.
After reading the above information, it is found that gas-mixed carbon black is still good. Although it was listed as a reserved variety before, in recent years, due to the rapid growth of plastics, ink and other industries, the demand for carbon black applications has continued to expand. Now there are many manufacturers. The carbon black is produced by the gas-mixed carbon black process.
