Embodiment 1

[0016] A method for processing plastic products, mainly comprising the following steps,

[0017] 1) Freezing, put the plastic products into the freezing room for processing, the freezing temperature is -100°C, liquid nitrogen is used as the refrigerant, and the freezing time is 3 hours;

[0018] 2) Breaking, crushing frozen plastic products;

[0019] 3) Separation, taking out structural parts in plastic products, etc.;

[0020] 4) Crushing, crushing the remaining plastic products, and controlling the crushing particle size to 300 mesh;

[0021] By adopting the above steps, plastic products can be effectively treated.

Embodiment 2

[0023] A method for processing plastic products, mainly comprising the following steps,

[0024] 1) Freezing, put the plastic products into the freezing room for processing, the freezing temperature is -80°C, using liquid nitrogen as the refrigerant, and the freezing time is 5 hours;

[0025] 2) Breaking, crushing frozen plastic products;

[0026] 3) Separation, taking out structural parts in plastic products, etc.;

[0027] 4) Crushing, crushing the remaining plastic products, and controlling the crushing particle size to 450 mesh;

[0028] By adopting the above steps, plastic products can be effectively treated.

Embodiment 3

[0030] A method for processing plastic products, mainly comprising the following steps,

[0031] 1) Freezing, put the plastic products into the freezing room for processing, the freezing temperature is -90°C, liquid nitrogen is used as the refrigerant, and the freezing time is 4 hours;

Abstract

The invention provides a plastic product processing method, belongs to the technical field of plastics, and aims to achieve the environment-friendly purpose. The technical scheme mainly comprises thesteps of freezing, breaking, separating and crushing, so that the plastic products can be effectively processed. At low temperature, the plastic product is easy to generate cracking phenomenon, the structure of the plastic product is damaged by low-temperature freezing, so that the plastic product is easy to crush, and the structural member in the product can be taken out to use as a filling material for other plastic products by crushing and can be degraded and used. The processing method has advantages of being scientific and reasonable, environmentally-friendly, high in processing efficiency, high in utilization rate, excellent in social and economic benefits, and good in popularization value.

Description

technical field [0001] The invention belongs to the technical field of plastics, and in particular relates to a processing method for plastic products. Background technique [0002] At present, with the coming of the expiry date, many plastic products have exceeded the expiry date and are in a state of pending disposal. Since plastic is a polymer elastomer material, it is not easy to degrade, and the burning treatment seriously pollutes the environment and has been expressly prohibited. Some products, such as tires, seals, etc., are bulky and difficult to handle. Therefore, how to deal with plastics more environmentally friendly has become a very critical issue. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a treatment method for plastic products to achieve the purpose of environmental protection. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted in the present...
