Shanghai Daoqin Plastics Co., Ltd.

  polypropylene (PP) (PP) is large general purpose plastics in development most fast types, widely used in industrial and day active in. however plastics products easy loss, easy aging, difficult degradation, waste plastics 越 越 more, 焚烧, and other methods not only ring 境, but also formed heavy 资源浪费. if can through recycling again utilizing waste plastics, 既经济 also environmental protection. 但PP in 甲基 存 in make its separation flexible reduce property increase, but also recycling PP in in a large amount of fiber and various additives and other 杂质, 进一步 increase its property, therefore for recycling PP toughened modified is its can again utilizing key/critical in, currently for/regarding recycling PP toughened research 报道甚 less, molding process formed 熟. another, PP熔化潜 hot large for temperature degree 敏感, molding temperature degree must control in relatively narrow scope/range can obtain most force property can; PP degree 受剪切 force effect/influence relatively large, injection molding pressure for its flow property generate very large effect/influence from 而改变 its most force property can; holding pressure time and holding pressure pressure in 一定程 degree upper effect/influence PP products force property can; and new PP versus ratio, recycling PP in due to 杂质 存 in make its property can unstable property increase, and injection molding processing process parameters between more add complex.

       is 此, as using/adopting positive experiment/testing recycling PP injection molding most process parameters, use modified POE以 and modified POE+ nano CaCO3 as is toughening agent separation for recycling PP进行 toughened 处理, research toughened rear PP property can.
