However, after years of use, fishing nets are prone to oxidation or cracking to a certain extent due to long-term immersion in seawater and exposure to sunlight, which affects the structural strength of fishing nets
[0003] Therefore, fishing nets become consumables, and a large number of waste fishing nets are discarded, increasing the burden on the environment
In addition, a large amount of sediment, aquatic plants, shells or garbage are entrained and adhered in the waste fishing net, making it extremely difficult to recycle the waste fishing net, and even if the waste fishing net is recycled directly, the mechanical properties of the nylon-6 obtained are no longer It can be reused and cannot be reused substantially

Embodiment Construction
[0032] The following examples illustrate possible implementations of the present invention, but are not intended to limit the protection scope of the present invention.
[0033] Please refer to figure 1 and figure 2 , the invention provides a method for recycling waste fishing nets, comprising the following steps:
[0034] Roughly chopping S11: Roughly chopping the waste fishing net 10 to facilitate subsequent steps such as picking out impurities, wherein the waste fishing net 10 is mainly composed of nylon-6;
[0035] Removing impurities S12: removing large impurities in the waste fishing net 10, such as shells, garbage, aquatic plants and sediment, etc. In the main embodiment, this step removes impurities by manual visual inspection;
[0036] Removal of metal impurities S13: use metal detectors to detect metal substances and remove them, so as to remove metal impurities that cannot be completely removed in the previous step, so as to avoid mechanical damage caused by meta...

Abstract
The invention provides a waste fishing net recovering and reproducing method. Fishing net wires are made by conducting cutting, impurities removing, cleaning, drying and the like on waste fishing nets in advance. The method includes the following steps of mixing raw materials, wherein the fishing net wires and nylon-66 are mixed, the fishing net wires account for 70% to 99.9% of the total weight, and the nylon-66 accounts for 0.1% to 30% of the total weight; conducting fusing, wherein the mixed fishing net wires and the nylon-66 are fused; conducting granulating, wherein the fused fishing net wires and the nylon-66 are granulated; conducting wire drawing, wherein wire drawing is conducted on raw material granules produced in the granulating step. Thus, the waste fishing nets are effectively recovered and reproduced, and then plastic materials high in practicability can be provided.
Description
technical field [0001] The invention relates to the technical field of remanufacturing, in particular to a recycling and remanufacturing method of waste fishing nets. Background technique [0002] Generally speaking, fishing nets are mostly made of nylon-6, and nylon-6 has good mechanical strength, high softening point, heat resistance, oil, acid and alkali, and has excellent processing characteristics. However, after years of use, fishing nets are prone to oxidation or cracking to a certain extent due to long-term immersion in seawater and exposure to sunlight, which affects the structural strength of fishing nets. [0003] Therefore, fishing nets become consumables, and a large amount of waste fishing nets are discarded, increasing the burden on the environment. In addition, a large amount of sediment, aquatic plants, shells or garbage are entrained and adhered to the waste fishing net, making it extremely difficult to recycle the waste fishing net, and even if the waste ...
