帮忙修改我的英译中:PVC processing materials? 请帮忙修改我的这段英文翻译中文!谢谢!! these materials are of prime importance in pvc processing.they: (1) improve the internal flow characteristics of the compound. (2) reduce the tendency for the compound to stick to the process machinery. (3) improve the surface smoothness of the finished product. (4) improve heat stability by lowering internal and/or external friction. examples of lubricants,with which you may be familiar,are stearic acid,calcium stearate,wax e,polyethylene ac 617. 我的翻译: 这些材料对于聚氯乙烯的加工来说是非常重要的。它们可以: (1)改善聚合物内部的流动特性。 (2)降低聚合物粘在加工机械上的倾向。 (3)改善成品的表面平滑性。 (4)通过降低内部和/或外部的摩擦来提高热稳定性。 以润滑剂为例,包括您可能熟悉的,有硬脂酸,硬脂酸钙, wax e,polyethylene ac 617(不知这两个怎么翻) 希望大家能多多指教!!查看更多
