Fluidized bed technology to let Gao Danghua Carbon Black

A few days ago, the Chinese Academy of Sciences, researchers recently developed a fluidized bed reactor can be common for ozone oxidation of ultrafine carbon black surface modification of special carbon black production.

The reactor due to the high-speed gas and special internal components, agglomerate particles can be effectively inhibited, with a gas-solid contact, heat transfer and high-efficiency particle backmixing less so on. Fluidized flow of granular materials, such as general, particulate materials can be realized in a row to join with the unloading, the formation of continuous operation. At present, in small test based on the coking plant in Shanghai has built a 4 m high, 125 mm diameter, the handling capacity of 500 g / hour in the hot test equipment to produce high-quality specialty carbon black.

Carbon Black is an important industrial raw materials, including carbon black oxide (also known as the special carbon black) of the dispersion, bonding, and so on, the color is better than non-black oxide, it is widely used in high-level ink, paint, ink, rubber , And other products. For a long time, China's special needs rely on imports of carbon black to resolve the successful development of products for special carbon black production of fluidized bed technology laid the foundation of China-made.
