Abrasion-proof energy-saving polyethylene fishing net

Abstract

The invention discloses a polythene fishing net with wear resistance and energy saving and relates to the filed of fishing gear manufacturing. The wear resistance of the fishing net needs to be improved. The invention adopts the preparation technology of the polythene fishing net and is characterized in that ultra-high molecular weight silicane and high molecular weight polyolefin are mixed with master batches of polyvinyl resin in proportion, wear resistant master batches which are blended in proportion and the polyvinyl resin are blended according to weight proportion, the weight of the wear resistant master batches is 2 percent to 5 percent of the weight of the polythene, the mixture is melt-extruded by an extruding machine, the fiber which is melt-extruded is put into a flume to be cooled and pre-drafted, and the cooled monofilament fiber is drafted. The drafting temperature is 90 to 105 DEG C, the drafting multiple is 11 to 13 times, the setting temperature of the drafted monofilament is 90 to 120 DEG C, the set monofilament fiber is coiled by the wrapping tension of 200 plus or minus 30cN and the coiling speed of 120 to 150 meters per min, and the monofilament is made into net wire of the twist number of 36 to 216 twists per meter and is woven into the wear resistant fishing net with the mesh size of 10mm to 1200mm.

Description

Technical field: [0001] The invention belongs to the fishing gear material manufacturing technology. Background technique [0002] Polyethylene (HDPE) fishing nets are damaged due to violent friction with metal and non-metal materials such as stones, cement, steel, and plastics during use. The scrapping and damage of net gear mainly comes from wear and tear, so the service life mainly depends on the wear resistance of its net gear. The existing polyethylene fishing net mainly improves the wear resistance by increasing the twist of the fishing net line when it is twisted. If the wear resistance of the fishing net is increased by about 15% to 20%, it is necessary to increase the twist of the fishing net line by 30%. The defect of high-twist polyethylene fiber fishing net internal twist and external twist is that the breaking strength of the fishing net will be lost by 20% to 30%. And the weight of the fishing net, not only the manufacturing cost is high, but also the weight...

AI Technical Summary

Problems solved by technology

The defect of high-twist polyethylene fiber fishing net internal twist and external twist is that the breaking strength of the fishing net will be lost by 20% to 30%. And the weight of the fishing net, not only the manufacturing cost is high, but also the weight of the mesh increases by 30%, which greatly increases the cost of using the net, which is equivalent to using 30% more polymer petroleum materials

Due to the large elongation percentage of high-twisted fishing nets, the nets are easily deformed or broken due to uneven force, the use and fishing effect is poor, and the use limitations are large.

The resulting large resistance of the tugboat results in a waste of power and fuel energy, resulting in high direct and indirect economic costs.
