Embodiment Construction

[0017] A method for disposing of unqualified products during the processing of polymer composite materials. A coating production line is used to separate the polymer material layer from the base fabric layer for products that have been determined to be unqualified products, and then separate the separated The polymer material layer and base fabric layer are recycled and reused.

[0018] A method for disposing of unqualified products during the processing of polymer composite materials. For polymer composite materials that are unqualified and meet the peel strength not greater than 2.0N / mm, a coating production line based on coating and bonding is used. The polymer-based coating layer is separated from the fabric layer, and then the separated polymer material layer and base fabric layer are recovered respectively.

[0019] On the basis of the above scheme, the material of the coating layer can be polyvinyl chloride, polyethylene, thermoplastic elastomer, etc.; the base fabric c...

Abstract

The invention relates to a method for disposing an unqualified product in a polymeric composite material processing process. The method comprises the following steps: for an unqualified polymeric composite material with the peeling strength not greater than 2.0N/mm, separating a polymer-based coating layer and a fabric layer by using a coating production line which integrates coating and laminating; recycling the polymeric material layer and the base material fabric layer respectively; no additional equipment is added, and the unqualified product is recycled and reused by using existing production equipment; loss of a processing enterprise is reduced as much as possible, and waste of resources is reasonably reduced.

Description

technical field [0001] The invention belongs to the technical field of polymer composite material manufacturing, and in particular relates to a method for disposing of unqualified products during the processing of polymer composite materials. Background technique [0002] Polymer composite material is a product whose surface is composed of polymer materials (such as PVC, TPU, TPO, etc.) and substrate fabrics (such as PET, non-woven fabrics, etc.). , calendering process, or extrusion process and other methods, the two are combined through a medium such as a binder. This kind of polymer composite material has been widely used in industry, agriculture, aerospace and other important fields of national economy. With the in-depth development of my country's reform and opening up, the manufacturing technology of the domestic polymer composite material processing industry has made great progress, and the quality of some products can already be compared with similar foreign products...
