Chenguang Chemical Research Institute adds sticky-recovery PET industrial waste technology transfer.
This project is applied to the chemical industry and the product is used as engineering plastics. In this technology, an active chain extender is added. In a parallel co-rotating twin-screw extruder, the chain extender undergoes an addition reaction with a terminal group in the molten PET molecule to achieve the purpose of thickening. The application of this technology can increase the intrinsic viscosity of 0.53 dl/g PET industrial waste to 0.68 dl/g, and build an annual production capacity of 500 tons of viscous recovery PET production equipment, can achieve direct recycling and reuse requirements. This technology has a domestic advanced level. Applying this technology to recycling PET not only meets the increasingly strong environmental protection requirements, but also can directly produce PET industrial wastes to produce high-performance engineering plastics, with significant social and economic benefits.
The application of this technology can directly produce high-performance engineering plastics from PET industrial wastes. This is a very reasonable and valuable PET recycling method. At present, there is ample supply of domestic PET industrial waste, and there are still a large number of waste PET bottles on the market. Recycling. Therefore, the application of this technology is promising.
