Carbon fiber pre-oxidation and carbonation furnaces/kilns exported to Korea
At the end of 2021, a Korean customer contacted Yanneng through an intermediary channel to customize the production of a PAN-based carbon fiber carbon Oxidation Furnace. After several rounds of communication, the drawings, plans and prices were finally determined. Production began in February 2022. The customer also proposed some improvement measures during the production process, and we also cooperated accordingly. The goods were delivered on time 5 months later and arrived in South Korea safely and intact by sea. In September, Yanneng sent technicians to the Korean customer's factory to install and debug the equipment, which ran smoothly.
Polyacrylonitrile carbon fiber (PAN-CF) obtains raw materials from petroleum. After spinning, it is oxidized at low temperature Celsius in Yanneng's patented oxidation furnace to produce a cross-linked structure. After carbonization through Yanneng Carbonization Furnace/kiln at high temperature with nitrogen, the fiber maintains a highly oriented structure. Finally, graphitization is carried out at a temperature of 2500-3000 degrees to further increase the degree of orientation. The modulus can reach 900GPa, which is close to the theoretical modulus of graphite single crystal 1060GPa
