Embodiment 1
[0101] In this embodiment, a method for recycling multi-component mixed plastic waste mainly includes the following steps:
[0102] (1) Mix the collected plastic waste according to the following ratio:
[0103] Polypropylene waste 60%,
[0104] Polyethylene waste 5%,
[0105] Polyethylene terephthalate waste 15%,
[0106] Nylon 6 waste 20%,
[0107] The mixed plastic waste obtained after mixing, after washing and drying, is processed into plastic film strips with a long diameter of no more than 1 to 5 cm as recycling mixtures;
[0108] (2) Add the recovered mixed material obtained in step (1) into a millstone-type solid-phase mechanochemical reactor for grinding and pulverization. After the milling is completed, an ultrafine hybrid powder is collected; The process parameters of the device are: 20 cycles of grinding, the grinding pressure of the 1st to 5th cycle grinding is 5MPa, the grinding pressure of the 6th to 20th cycle of grinding is 8MPa, the speed of the grinding d...

[0112] In this embodiment, a method for recycling multi-component mixed plastic waste mainly includes the following steps:
[0113] (1) Mix the collected plastic waste according to the following ratio:
[0114] Polypropylene waste 60%,
[0115] Polyethylene waste 5%,
[0116] Polyethylene terephthalate waste 15%,
[0117] Nylon 6 waste 20%,
[0118] The mixed plastic waste obtained after mixing, after washing and drying, is processed into plastic film strips with a long diameter of no more than 1 to 5 cm as recycling mixtures;
[0119] (2) Add the recovered mixed material obtained in step (1) into a millstone-type solid-phase mechanochemical reactor for grinding and pulverization. After the milling is completed, an ultrafine hybrid powder is collected; The process parameters of the device are: 30 cycles of grinding, the grinding pressure of the 1st to 5th cycle grinding is 5MPa, the grinding pressure of the 6th to 30th cycle of grinding is 8MPa, the speed of the grinding d...

[0134] In this embodiment, a method for recycling multi-component mixed plastic waste mainly includes the following steps:
[0135] (1) Mix the collected plastic waste according to the following ratio:
[0136] Polypropylene waste 60%,
[0137] Polyethylene waste 5%,
[0138] Polyethylene terephthalate waste 15%,
[0139] Nylon 6 waste 20%,
[0140] The mixed plastic waste obtained after mixing, after washing and drying, is processed into plastic film strips with a long diameter of no more than 1 to 5 cm as recycling mixtures;
[0141] (2) Add the recovered mixed material obtained in step (1) into a millstone-type solid-phase mechanochemical reactor for grinding and pulverization. After the milling is completed, an ultrafine hybrid powder is collected; The process parameters of the device are: 30 cycles of grinding, the grinding pressure of the 1st to 5th cycle grinding is 5MPa, the grinding pressure of the 6th to 30th cycle of grinding is 9MPa, the speed of the grinding d...
