2008～2011年期间在东海所对共混改性聚丙烯聚乙烯(PP/PE)编织线进行了初步研究。结果表明,共混改性PP/PE编织线具有断裂强力高的特性,在保持网线断裂强力优势的前提下,以共混改性PP/PE编织线替代普通乙纶(PE)捻线用作网线,能使网线线密度减小、使用直径减小、原材料消耗减小,相关渔具或网箱的水阻力也相应减小,从而实现渔业生产的节能降耗;在保持同等直径的前提下,共混改性PP/PE编织线较相同直径的普通PE捻线具有相对较好的物理性能,其渔用性能及渔用适配性也相对较好;在保持网线断裂强力优势的前提下,使用共混改性PP/PE编织线比使用普通PE捻线更经济,其在渔业生产中推广应用上具有经济可行性。结论可供渔具或网箱设计及网线材料选配时参考。
During the period from 2008 to 2011 in the East China Sea, the blending modified polypropylene polyethylene (PP / PE) braided wire was studied. The results show that blends of modified PP / PE braided wire have the characteristics of high breaking strength. Under the precondition of keeping the breaking strength of the net wire, the blended modified PP / PE braided wire is used instead of ordinary PE fiber twisting wire The network cable can reduce the density of the wire and the diameter of the wire used to reduce the consumption of raw materials to reduce the water resistance of the relevant fishing gear or cage in order to save energy and reduce consumption of fishery production; under the premise of maintaining the same diameter, Blending modified PP / PE braided wire has relatively better physical properties than ordinary PE twine with the same diameter, and its fishing performance and fishing adaptability are also relatively good. On the premise of maintaining the advantage of breaking strength of the net cable, The use of blended modified PP / PE braided wire is more economical than the use of ordinary PE twine, which is economically feasible in the promotion and application of fishery production. Conclusion Available for fishing gear or cage design and network cable material selection reference.
