| 摘要: |
| 对未加稳定剂和抗氧剂的渔用高强度聚乙烯(High-strength polyethylene,简称HSPE)单丝进行了自然暴露老化和人工加速老化试验研究。结果表明:渔用HSPE与普通聚乙烯 (polyethylene,简称PE)单丝的耐老化性能有一定的差异;从一定条件下断裂强度保持率和断裂伸长率保持率这2种指标来看,渔用HSPE单丝具有优势,HSPE单丝耐老化性能优于普通PE单丝。自然暴露老化和人工加速老化所得出的两种试样的耐老化性基本一致。 |

| Abstract: |
| Outdoor exposure ageing test and artificial accelerated ageing test of high-strength polyethylene(HSPE) monofilament without stabilizers and antioxidants were studied in laboratory. As a result, there are some differences in ageing stability between HSPE and common polyethylene(PE) monofilament, according to preservation rate of breaking strength and preservation rate of percentage of breaking elongation under given conditions, the former has a superiority in ageing stability, the ageing stability of HSPE monofilament is better than that of common PE monofilament. The results got from outdoor exposure ageing test and artificial accelerated ageing test are consistent on the whole. |
