PVDF polyvinylidene fluoride granulation production equipment
The invention discloses a special granulating extruder for PVDF, which includes two parallel screws, a barrel outside the screws, a heating system, a cooling system, and an evacuation devolatilization system. The barrel is provided with a fluorine gas exhaust port , Designed to improve production efficiency without oxidation, can simply and effectively remove unstable end groups in products and control product volatility, and at the same time have the characteristics of high temperature and corrosion resistance and long service life. Twin screw extruder, the twin screw extruder of the present invention The function can effectively remove the unstable end groups in the molecular chain and control the volatile content of the product. At the same time, the barrel has corrosion resistance and high temperature deformation resistance, which is very suitable for PVDF processing.
