摘要
悬臂梁缺口冲击强度是考察塑料耐候性的主要指标之一,本文通过对 3 种塑料经过氙灯暴露、荧光紫外灯暴露后的悬臂梁缺口冲击强度值的对比分析,清晰表明了在塑料缺口冲击强度试样的耐候性试验中,其暴露方向和安装方式直接影响试验后的缺口冲击强度值,因此,对于塑料光源暴露试验后的缺口冲击强度,无论在设计光源暴露试验方案还是在应用测试结果时,都宜指明试样的暴露方向和安装方式.
Abstract
The izod notched impact strength is a main property to inspect the weatherability of plastics.This paper analysed izod notched impact strength values of three different types of plastics after Xenon-arc exposure or Fluorescent UV exposure,and reveals that the exposure direction and the installation mode of specimens in the exposure tests have direct effects on the test values,so the exposure direction and the installation mode of specimens should be stated clearly whether in designing exposure test programme or in applying the test results.
