Abstract

The invention discloses a PET slice production system and the production process of the PET slice production system, aiming to provide a PET slice production system with high production efficiency, low energy consumption, high quality and high output, and a simple , convenient and efficient production process of the PET chip production system. The PET chip production system includes a polyester device, a solid-phase polycondensation device, and several buffer bins (1) arranged between the polyester device and the solid-phase polycondensation device. The production process of the PET chip production system includes slurry preparation, esterification reaction, pre-condensation reaction, final polycondensation reaction, pelletizing, storage, pre-crystallization, slow preheating, solid-state polycondensation reaction, cooling, gas purification and material storage . The invention is applied in the technical field of producing PET slices.

Description

technical field [0001] The present invention relates to a PET slice production system, and also relates to a production process of the PET slice production system. Background technique [0002] At present, polyethylene terephthalate, Polyethyleneterephthalate, referred to as PET, is a common resin in life. PET is a milky white or light yellow, highly crystalline polymer with a smooth and shiny surface. It has excellent physical and mechanical properties in a wide temperature range. The long-term use temperature can reach 120 ° C. It has excellent electrical insulation. Even at high temperature and high frequency, its electrical properties are still good, but its corona resistance is poor. Creep resistance, fatigue resistance, friction resistance and dimensional stability are all very good. PET has ester bonds, which will decompose under the action of strong acid, strong alkali and water vapor, and has good resistance to organic solvents and weather resistance. The disadva...
