详细描述了含有熔合线的模塑板中等规聚丙烯的形态。讨论了模具温度和流动对球晶和穿晶区域的尺寸和取向的影响。通过光学显微镜分析单轴拉伸应力下焊缝处的变形。
The morphology of isotactic polypropylene in molded plaques containing a knit line is described in detail. The effects of mold temperature and flow on the size and orientation of spherulitic and transcrystalline regions are discussed. Deformation at the weld line under uniaxial tensile stress is analyzed by optical microscopy.
