Problems solved by technology

[0003] The complex sources of recycled plastic substrates, the confusion of enterprise particle quality control regulations, the simple quality evaluation system, and the lack of industry product standards all reduce the transaction efficiency of recycled plastic products and push up transaction costs.
Restricted trading of recycled plastic products also affects the recycling of plastic renewable resources

Abstract

The invention relates to the field of recycled plastic quality evaluation, and provides a multi-dimensional quality evaluation method for recycled plastic. The method at least comprises physical and mechanical property test, safety test, color test, impurity quantitative test, molding surface test, odor grade test and metal content test. The method is used for evaluating the quality of the recycled plastic from multiple different aspects, is comprehensive and accurate, has very high practicability, can improve the market value of recycled products of the recycled plastic, is beneficial to recycling and re-classification, and realizes real resource cyclic utilization.

Description

technical field [0001] The invention relates to the field of quality evaluation of recycled plastics, in particular to a multi-dimensional quality evaluation method of recycled plastics. Background technique [0002] Recycled plastics refer to the plastic raw materials obtained after processing waste plastics through physical or chemical methods such as pretreatment, melting granulation, and modification. It is the reuse of waste plastics. [0003] The complex sources of recycled plastic substrates, the confusion of enterprise particle quality control regulations, the simple quality evaluation system, and the lack of industry product standards all reduce the transaction efficiency of recycled plastic products and push up transaction costs. The limited trading of recycled plastic products also affects the recycling of plastic renewable resources. In order to promote the recycling and classification of waste plastics, reduce the harm caused by plastic waste to the environment...
