2008年～2010年期间在东海水产研究所对渔用四股改性聚丙烯聚乙烯(PP/PE)绳索进行了研究。结果表明,渔用四股改性PP/PE单丝绳索具有强力高的特性,在保持强力优势的前提下以渔用四股改性PP/PE单丝绳索替代具有GB/T18674标准合格品指标的普通四股聚乙烯(PE)单丝绳索用作渔用绳索,能使绳索线密度减小、使用直径减小、原材料消耗减小、绳索阻力减少,从而实现渔业生产的节能降耗。渔用四股改性PP/PE单丝绳索为节能降耗型渔具或网箱的研制提供了配套材料,具有一定的安全效果和经济可行性,能在我国渔业中应用并推广。
Four strands of modified polypropylene polyethylene (PP / PE) ropes were studied at the Tokai Fisheries Research Institute from 2008 to 2010. The results showed that the fishing four modified PP / PE monofilament ropes with high strength characteristics, while maintaining the strength advantage under the premise of fishing with four strands modified PP / PE monofilament ropes with GB / T18674 standard eligibility indicators of the ordinary Four strands of polyethylene (PE) monofilament rope for fishing rope, rope density can be reduced, the use of reduced diameter, reducing the consumption of raw materials, rope resistance to reduce, so as to achieve energy saving of fishery production. Fishing four modified PP / PE monofilament ropes provide supporting materials for the development of energy-saving fishing gear or cages with certain safety effects and economic feasibility, which can be applied and popularized in fisheries of our country.
