Problems solved by technology

Since plastic is a polymer material, it is not easy to degrade, and it is directly buried, which not only wastes precious land resources, but also has an impact on the soil. Combustion treatment seriously pollutes the environment and produces dioxin, which has been expressly banned

Embodiment 1

[0016] A kind of recycling method of plastic film, mainly comprises the following steps,

[0017] 1) Precipitation, rinse with water in the pool, and after standing for 1 day, remove impurities such as soil;

[0018] 2) washing, cleaning the plastic film with acetone to remove organic matter such as oil stains;

[0019] 3) Press filter, adopt mechanical press filter, and adopt ceramic film filter, press plastic film, and filter out its residual solvent and water etc.;

[0020] 4) pulverizing, pulverizing the plastic film after press filtration to 400 mesh;

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

Abstract

The invention belongs to the technical field of plastic recycling and discloses a recycling method for plastic films to ensure the purpose of treating the plastic films in an economical and environment-friendly manner. According to the technical scheme, the recycling method mainly comprises the steps of precipitating, washing, filter pressing and smashing. By means of the steps, impurity and oil contamination removing and the like are completed for the plastic films; by means of smashing, the plastic films are made into plastic particles, and due to the fact that the plastic films contain a large number of high molecular materials, the plastic films can be used in a degradation manner, can serve as padding of other rubber or plastic products and can be recycled. The treatment method is scientific, reasonable, environmentally friendly and high in treatment efficiency and utilization rate and has excellent social and economic benefits and popularization value.

Description

technical field [0001] The invention belongs to the technical field of plastic recycling, and in particular relates to a method for recycling plastic films. Background technique [0002] In daily life and scientific research and production, a large number of discarded plastic films are produced every day, such as catering, packaging and protection. Since plastic is a polymer material, it is not easy to degrade, and it is directly buried, which not only wastes precious land resources, but also has an impact on the soil. Combustion treatment seriously pollutes the environment and produces dioxin, which has been expressly banned. Therefore, how to deal with plastic films 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 plastic film recycling method to ensure economical and environment-friendly processing of the plastic film. [0004] In order to solv...
