摘要
选取透气膜、隔汽膜、硅酮密封胶膜片、聚乙烯膜、自粘片材等多种膜类片材,按照JC/T 2291—2014(2017)《透汽防水垫层》中的水法(减重法)进行水蒸气透过量测试,对不同面迎水和采用不同边缘密封方式下的测试结果进行对比分析,在此基础上总结影响因素,减少因操作而带来的检测误差。
;Breathable film,air impervious film,silicone sealing membrane,PE film,self-adhesive membrane and many other membrane sheets are chosen to have vapor transmission tests as per the water method(loss of weight)of JC/T 2291——2014(2017)"Water resistive&vapor permeance barriers".The article compares and analyzes the testing results obtained by facing water with different sides and adopting different edge sealing methods,and it summarizes the influential factors on this basis to reduce test deviations due to operation problems.
