PVDF Production Line/Pelletizing Line/Twin Screw Extruder

The solvable fluoroplastic which represent by FEP(F46) can generate unstable terminal during the process of powder granulation and compounding. This ustable terminal must be devolatilized.

At same time, the powder needs stabilizing treatment with high temperature melting in order to get rid of the small molecule volatile like solvant, emulsifier. Normally, the temperature can reach to 380~390ºC. In this heat , the unstable terminal will break out that may generate HF which is very corrosive. The HF can easily corrode the machine parts, especially the screw, barrel, exhaust chamber and the head.

In recenty ten years, Chuangbo has accumulated  lots of experience in the field of fluoroplastic process and solved many key technical problems, such as the machine configure, the design, research and development of the new kind of feeding and dosing system, the parameter optimization, the development of special screw elements and the  design of screw structure, the improvement of special barrel with anti-corrosion and of the structure of the  exhaust chamber,...

Typical  Application

  
F46, PFA, PVDF. F40 powder granulation and stablization; The compounding of Fluorin materials and non-flurin materials
