Problems solved by technology

[0002] Due to the structural characteristics of the twisted mesh, the strength of the twisted mesh mainly depends on the strength performance of the monofilament. For ultra-high molecular weight polyethylene, due to its super performance and high-strength utilization ratio, the mesh has However, due to the special process required in the weaving process of UHMWPE fiber and the extremely high production cost, the high price seriously restricts its promotion, and the demand for high-strength mesh in the fishery industry High-strength polyethylene monofilament has the advantages of low price and high performance-price ratio. Compared with ordinary polyethylene, it has high strength and low weight. Lightweight, wear-resistant, aging-resistant, and high performance-price ratio. Therefore, it has been widely used in fishery production fields such as trawls, cages and sea anchor ropes, and has achieved good results. However, with deep-water cage culture and tuna The rapid development of the purse seine has put forward higher requirements for the strength and comprehensive performance of the twisted mesh, but my country has little research on related technologies. Therefore, it is necessary to conduct in-depth research on how to enhance the strength of the twisted mesh

Embodiment 1

[0013] A processing method of high-strength polyethylene twisted mesh, mechanically stretching the high-strength polyethylene twisted mesh to make its length reach 103% of the product specification, and then pushing the grid frame and the stretched mesh into the Carry out shaping in the shaping kettle, the specific content is, after closing the shaping kettle, feed nitrogen into the shaping kettle, and pump out air from the other side until it is detected that there is no oxygen in the shaping kettle, then stop; then pass benzene vapor into the shaping kettle , stop when the pressure in the shaping kettle reaches 300kPa, raise the temperature to 116°C, keep it for 8 minutes, open the exhaust valve to discharge the benzene vapor in the kettle; then take out the mesh, soak it in water with a temperature of 12°C for 14 minutes, and then The above-mentioned high-strength polyethylene twisted mesh after the first shaping is stretched to make the length reach 107% of the product spec...

Embodiment 2

[0019] A processing method of high-strength polyethylene twisted mesh, the high-strength polyethylene twisted mesh is mechanically stretched to make its length reach 102% of the product specification, and then the grid frame and the stretched mesh are simultaneously pushed into the Carry out shaping in the shaping kettle, the specific content is, after closing the shaping kettle, feed nitrogen into the shaping kettle, and pump out air from the other side until it is detected that there is no oxygen in the shaping kettle, then stop; then pass benzene vapor into the shaping kettle , stop when the pressure in the shaping kettle reaches 320kPa, raise the temperature to 114°C, keep it for 8 minutes, open the exhaust valve to discharge the benzene vapor in the kettle; then take out the mesh, soak it in water at a temperature of 15°C for 10 minutes, and then The above-mentioned high-strength polyethylene twisted mesh after the first shaping is stretched to make the length reach 106% o...

Embodiment 3

[0023] A processing method of high-strength polyethylene twisted mesh, mechanically stretching the high-strength polyethylene twisted mesh to make its length reach 104% of the product specification, and then pushing the grid frame and the stretched mesh into the Carry out shaping in the shaping kettle, the specific content is, after closing the shaping kettle, feed nitrogen into the shaping kettle, and pump out air from the other side until it is detected that there is no oxygen in the shaping kettle, then stop; then pass benzene vapor into the shaping kettle , stop when the pressure in the shaping kettle reaches 300kPa, raise the temperature to 114°C, keep it for 8 minutes, open the exhaust valve to discharge the benzene vapor in the kettle; then take out the mesh, soak it in water at a temperature of 15°C for 10 minutes, and then The above-mentioned high-strength polyethylene twisted mesh after the first shaping is stretched to make the length reach 106% of the product specif...

Abstract

The invention belongs to the technical field of fishing gear processing, and in particular relates to a processing method of high-strength polyethylene twisted net sheet, which includes primary benzene steam setting, cooling and secondary hot steam setting. Compared with the prior art, the present invention has the following advantages: in the present invention, when the linear density is slightly increased by adding compounding additives to the high-strength polyethylene monofilament raw material, the tensile mechanical properties are also improved to a certain extent, and at the same time The woven mesh is stretched once and the benzene steam is set for the first time to modify the mesh, so that the spatial structure is more complex, the molecular structure is tighter, and the strength is increased; the mesh is stretched twice and the hot steam is set, reducing The retraction rate of the mesh is improved, and the product quality of the fishing net is guaranteed. Compared with the mesh of the same specification, the breaking strength is increased by about 3.5%, and the scope of application is wider.
