一、概述 国内外对树脂、塑料之类的固化度测定方法,大多数是属于破坏性测试。例如拉伸、弯曲、冲击强度的测定;悬臂梁破裂时的挠角的测定等机械性能方面的测定;在热学性能方面有热重量分析法、差热分析等方法。方法固然方便,但需较长的时间,还不是逐渐进行固化的测定方法的方向;而测定树脂塑料的光学性能及电性能作为非破坏测试其固化度的手段,仅限于实验室对小试样 First, an overview of domestic and foreign resin, plastics and other methods of measuring the degree of cure, most are destructive testing. Such as measurement of tensile strength, bending strength and impact strength, measurement of the bending angle at the time of breaking of the cantilever beam, and other mechanical properties, and thermal gravimetric methods and differential thermal analysis methods. Method is convenient, but takes a long time, is not the direction of the method of gradually curing; and the determination of optical and electrical properties of plastic resin as a means of non-destructive testing of its curing degree, limited to laboratory samples of small
