PVC粒点缺陷与填料粒径的关系
Relationship between Particle Defects of PVC and Filler Size
-
摘要: 本文利用概率密度图对填料粒径进行研究,确定填料粒径符合正态分布。利用等方差检验对PVC粒点缺陷不同水平进行分析,确定不同水平PVC粒点缺陷相关的填料粒径的方差一致性。利用假设检验对不同水平的PVC粒点缺陷的填料粒径均值进行分析,确定不同水平的PVC粒点缺陷相关的填料粒径的均值一致性。利用不同水平PVC粒点缺陷的相关填料粒径的正态分布,确定填料粒径的控制要求。Abstract: Possibility density diagram is applied to study filler size distribution to confirm if filler size is accordance to nominal distribution.Equal σ2 is applied to study filler size deviation of different level of PVC particle defects and confirm its uniformity.Hypotheses are applied to study filler size average of different PVC particle defects level and confirm its uniformity.Filler size distribution is studied to define its control specification.
