  • Patent number: 11926709
    Abstract: A method for recycling waste polyester, in particular to a method for recycling waste polyester by a modified alcoholysis method to recycle waste polyester to prepare dimethyl terephthalate (DMT), is provided and belongs to waste polyester recycling technology field. The waste polyester after dewatering and deoxygenation treatment is used as a raw material, in the step of feeding in melted state the alcoholysis agent is added in the melted waste polyester for preliminary alcoholysis, and the alcoholysis agent is ethylene glycol. On one hand, alcoholysis reaction occurs when the waste polyester raw material are melted, and at the same time, the viscosity of the melted material is reduced. Thus, the melted material remains melted at the alcoholysis temperature and is not easy to solidify again after entering the alcoholysis tank, ensuring that the alcoholysis is carried out under homogeneous conditions.

  • Patent number: 11655351
    Abstract: The invention present invention belongs to waste polyester recycling technology field and relates to a method and a device for recycling waste polyester, in particular to a method and a device for recycling waste polyester by modified chemical method to recover waste polyester to prepare dimethyl terephthalate (DMT). The recycling method of the present invention uses a process of continuous feeding, continuous alcoholysis and continuous transesterification. It can make the material undergo homogeneous alcoholysis in the melted state, and the required alcoholysis time is short. Because more than two alcoholysis tanks are used in series for continuous alcoholysis, the product quality of alcoholysis product is stable. When the alcoholysis product is continuously transesterified, it avoids the occurrence of side reactions and the unstable quality of the transesterified product, and the purity and yield of recycling product of waste polyester are greatly improved.

  • Patent number: 11572452
    Abstract: The present invention is in related to a method for recycling a waste polyester material, more particularly to a method for recycling the waste polyester material through a chemical way to produce DMT. It belongs to the technical field of recycling and utilization of waste polyester materials. The present invention adopts the technology of continuous feeding and continuous alcoholysis, so that the material undergoes homogeneous alcoholysis in a melting state, and the required alcoholysis time is short. Two or more alcoholysis tanks are used in series for continuous alcoholysis. The product quality is stable. At the same time, due to the optimization of the amount of EG in the alcoholysis process, distillation and concentration are not required after the alcoholysis step is completed. The alcoholysis product is directly entered into the transesterification tank for the transesterification reaction, and pure DMT products can then be generated.

  • Patent number: 7771189
    Abstract: Injection molding apparatus has upper and lower mold halves that split along the center line of the parison cavity and the gate passage leading thereto. Each hot melt injection nozzle is received within a tubular insert cup having a reduced diameter tip that is seated within the gate passage. The cup is supported on the lower mold half so as to remain thereon as the upper mold half opens and closes the mold. The base end of each nozzle has a swivel ball and socket relationship with the manifold block which supplies it with hot melt, while the tip end of each injection nozzle is configured to permit swivelling within the insert cup as need be to accommodate dimensional changes that arise during non-uniform thermal expansion and contraction of different parts of the tooling.
