摘要
简介了美式落锤法的术语和测试方法,从挤出工艺、模具、配方3个方面分析了PVC型材美式落锤冲击性能的影响因素,并给出了提高美式落锤冲击性能的具体措施,还介绍了美式落锤冲击性能的意义与用途,以及应用中的注意事项。
The terminology and test method of American falling weight were briefly introduced. Fac- tors of influencing the American falling weight impact property of PVC profiles were analyzed in three as- pects, i.e. extrusion process, mould and formula. Concrete measures for improving the American weight impact property were proposed. The significance and use of American ty were introduced as well as matters needing attention during its application. falling falling weight impact proper-
