渔用自增强聚乙烯单丝的拉伸力学性能分析
Analysis of tensile mechanic performance of self-reinforced polyethylene monofilament for fishing gear
【摘要】 在标准实验室环境里,对渔用自增强聚乙烯(self reinforcedpolyethylene,简称SRPE)单丝的结晶形态、拉伸力学性能进行了分析。结果表明:渔用SRPE单丝结晶度、声速值比普通聚乙烯(polyethylene,简称PE)单丝均有提高,其内部生成了串晶结构;SRPE单丝断裂强度、结节强度和结强损失率比普通PE单丝分别提高了12.75%、4.82%和12.69%,而断裂伸长率降低了27.72%。结论可供渔具设计及网线材料选配时参考。
【Abstract】 The structure and tensile mechanic performance of self-reinforced polyethylene (SRPE)monofilament for fishing gear have been analyzed in standard laboratory. Compared with common polyethylene (PE)monofilament, SRPE monofilament gets a bit higher crystallization, sonic velocity value, and the morphology of the SRPE monofilament was shish-kebab structure; the SRPE monofilament is 12.75%,4.82% and 12.69% higher than the common PE monofilament in breaking strength ,knot breaking strength and rate of loss of knot breaking strength , respectively, while in percentage of breaking elongation the latter is 27.72% higher than the former. The conclusion reached can be used as reference in designing fishing gear and selecting netting materials.
