Free Pre Drying and Crystallization PET Material Extrusion Calendering Forming



PET-79K.jpg



Free Pre Drying and Crystallization PET Material Extrusion Forming system:

PET material hygroscopicity is strong, if the moisture content too high, hydrolysis will occur under high temperature processing, so drying treatment before processing in traditional technology is necessary. Facing this feature, CENMEN developed modified drying free directly forming technic: using self-developed exhaust extruder, vacuum exhaust system, sheet forming auxiliary machine or granulating auxiliary machine form a complete set of free pre-drying and dehumidification PET production line. At the same time, CENMEN drying free directly forming technic has gradually replacing the traditional drying treatment wildly in sheet forming, recycled pelletizing industries, the large amount of energy consumption and time consumption in the original dehumidification and drying process are eliminated.


Free Pre Drying and Crystallization PET Material Twin Screw Extruder:

2-3 Vacuum exhaust chamber, large opening sized barrels are equipped with this twin screw extruder. Roots vacuum pump set, which includes optimized first stage water ring pump and second stage roots pump, can provide high extraction rate and vacuum, rapid removal of water and small molecular organic matter in PET, prevent large degree of hydrolysis. The extruder also sets up with natural exhaust opening, vaporize the moisture before PET is completely melt, in order to reduce the thermal degradation in the process of melting, the weak shear element should be used in the melting section and the melt conveying section of the screw structure. High torque low speed type of transmission case, the set running speed for the extruder is 250-300 rpm, since high screw speed will produce high shearing rate, which will lead to the rapid increase of material temperature.
