PET is a widely used engineering plastic with strong hygroscopicity. If the moisture content is too high, it will hydrolyze under the high temperature processing, causing PET molecular chain breakage and thermal decomposition to produce acetaldehyde. The physical and mechanical properties of PET are degraded, affecting Quality of products. Therefore, it is necessary to use PET crystallization dryer, PET raw materials for dehumidification drying, the moisture content within the normal control, ensure a good product quality.
PET crystallization dryer advantages:
1, simplify and improve the desiccant dryer raw material drying efficiency, speed up the production speed;
2, the process temperature can be accurately controlled by the thermostat;
3, increase the proportion of recycled materials used in the new PET materials to avoid waste;
4, constant speed stirring design so that the plastic does not crystallize in the crystalline phase of the process temperature does not form into blocks, high crystallization efficiency and uniformity;
5, the raw material can be dried at high temperature, and the drying process can be used directly to the existing standard drying bucket, reducing equipment costs;
6, a double overheating protection device to reduce accidents caused by human or machine failure;
7, Optional vacuum hopper, suction machine, magnetic base, suction box for transportation, convenient and quick.
