Manufacturing method of ultra high molecular weight polyethylene fiber composite meshes

Abstract

The invention discloses a manufacturing method of ultra high molecular weight polyethylene fiber composite meshes. The material is mainly used for the fields of fishing, fishery breeding and the like.The manufacturing method of the composite material comprises the following steps: placing a waterborne polyurethane resin solution in a solution pond, dipping the meshes in the solution pond, then feeding the meshes into a shaping machine by a transmission device through the solution pond, stretching, drying and shaping the meshes, carrying out primary treatment and then drying the meshes, and then repeatedly treating the meshes to obtain the finished product. In the aspect of the fishery breeding, the ultra high molecular weight polyethylene fiber meshes treated by the method are environmentally friendly and pollution-free, furthermore, the strength and wear resistance of the meshes can further be enhanced, influences of water flow retarding, bait stopping and oxygen stopping due to harmful adhesion of marine organisms can further be avoided, and the yield and quality of aquatic products which are bred by net boxes and net cages are improved.

Description

technical field

[0001] The invention relates to an ultra-high molecular weight polyethylene fiber composite mesh used in deep sea culture. Background technique

[0002] In terms of fish farming, especially deep-sea farming, deep-sea cages are set in the ocean and are greatly affected by wind, waves and currents. The structural materials of deep-sea cages are not only the frame, but also the mesh material is the main factor affecting its performance. Therefore In the deep sea environment, there are high requirements on the strength, corrosion resistance and impact resistance of the net, and marine organisms are easy to attach to the net cage, resulting in blocked water flow, blocking bait and oxygen, and reducing the net cage and cage culture. The output and quality of aquatic products, and the cages may be attacked by large marine predators in the deep sea, so how to choose and manufacture the nets of high-strength deep-sea cages has become an urgent problem to be solved. ...
