无卤阻燃聚乙烯燃烧性能测试影响因素分析

Analysis on Factors of Flammability Testing of No-halogen Flame-Retardant PE

采用氧指数和烟密度分析方法,对无卤阻燃聚乙烯试样燃烧性能测试的影响因素进行了分析。经过制备不同厚度和不同型制的试样,采用不同处理条件和点燃方式,分别探讨了在测试过程中各种因素对氧指数和烟密度的影响。

The factors of flammability testing of no-halogen flame-retardant PE were investigated by testing methods of the oxygen index and the smoke density. From making different thickness and different type of sample, the effects of testing oxygen index and smoke density were discussed respectively by using different standard atmospheres conditioning times and different sample ignition method.
