【摘要】 介绍了利用算图求阻隔性包装膜透氧率的图算法。用文中的算图能方便迅速地求出厚度为２～１００μｍ的ＰＶＣ、ＰＥＴ、ＯＮＹ、Ｂａｒｅｘ２１０、ＫＰＰ、ＰＶＤＣ、ＥＶＯＨ等聚合物薄膜在１０～６０℃温度范围内的透氧率和氧渗透系数。更多还原

【Abstract】 A nomograph for evaluating oxygen transmission rate of some barrier plastic films was introduced in this paper. The oxygen transmission rate of some polymers, such as PVC,PET,O NYLON,KPP,PVDC,EVOH,in the thickness of 2 100μm and at temperature range from 10 to 60℃ can be evaluated simply and direct by using this nomograph.更多还原
