Description

Technical field [0001] The invention relates to a compound synthesis device, in particular to an ethylene-vinyl acetate copolymer production device. Background technique [0002] Ethylene-vinyl acetate copolymer can replace part of PVC and rubber, and can also be used for cable sheaths, packaging and agricultural films, foam products, medical materials, calcium plastic materials, laminated materials, gaskets and hot melt adhesives. Most of the existing production devices are relatively complicated. The ethylene-vinyl acetate copolymer is used as a medical material. The advantages and disadvantages of the production devices are of great economic significance for improving product quality and reducing by-product content. Summary of the invention [0003] The purpose of the present invention is to provide an ethylene-vinyl acetate copolymer production device, which mainly includes: primary compressor (J101), secondary compressor (J102), tubular reactor (D101), high-pressure circulati...
