聚氯乙烯(PVC)熱穩定性差,在100℃時就開始分解,高于150℃時分解更加迅速,而PVC的工溫度約為160℃以上⋯,需要加入各種穩定劑;同時為了提高PVC的物理性能,PVC樹脂中也需要加入各種改性添加劑,這些穩定劑和改性添加
劑對PVC的加工性能將產生不同的影響,通過研究PVC的流變行為可以了解PVC加工性能。系統地研究各種添加劑對PVC的流變性能的影響有利于在PVC加工過程中尋找最佳的添加劑種類和配方2,經濟合理地制造出高品質的PVC制品。本文對國內外的多種PVC添加劑及用量進行了研究,以分析各類添加劑對PVC流變性能的
影響,為改善PVC加工性能提供理論參考。 。以上文獻若需轉載請備注出處:pbt塑料 //shanglikaiguan.cn/
