Polyester waste recovery
Recycling of polyester waste the recycling process of waste blocks and waste silk produced by polycondensation, spinning, drawing and other processes during the production of polyester.
The main products are :(1) the waste materials are digested by methanol, dimethyl terephthalate is prepared, ethylene glycol and terephthalic acid are prepared by hydrolysis or acidolysis, or sodium salt and ethylene glycol of terephthalic acid are prepared by alkaline hydrolysis, and the products are refined and used as raw materials for reuse;
