Natural gas tank method Carbon Black Powder uses natural gas as raw material, which is fed into the combustion chamber by iron pipes. The combustion chamber is long and short, made of iron plates, and there are several ethylene burners in the chamber. The natural gas is sprayed out from the burner with proper force, and burnt in the case of insufficient air, that is, a bright and black smoke flame is formed, which makes it rush to the bottom of the channel iron, and the distance between the burner and the surface of the channel iron is 65~ 80mm. At this time, the burning temperature drops from above 1000°C (about 1200-1400°C) to about 500°C, carbon black is deposited here, and the channel iron can move back and forth horizontally at a speed of 3-4mm/s. In order to maintain normal production, the required air volume is about 2.5 to 3 times the theoretically calculated amount. The resulting Carbon Black Powder is scraped into the hopper with a fixed scraper and sent to the central packaging room for processing. This kind of carbon black is soft. After being screened to remove hard particles and scale, it is sent to a mill for grinding to make the thickness more uniform, but the body is still very light and swollen. It should be shaken to make it slightly firmer, and then use Carbon Add a small amount of water to Black Powder to make it into a slurry, and rotate it with a small needle to make it into tiny pellets. After drying, it is the finished product. As far as Carbon Black Powder is used for pigments, in order to facilitate dispersion, most of them do not need to be granulated.
The process is as follows: raw material gas, air → combustion and cracking → collection → granulation → packaging → finished product
