中文摘要:
      目的 检测非PVC储液软包的密封性, 提出合理检测储液软包是否渗漏的判别标准。方法 对样品在外界压力作用下压强的变化进行理论分析, 并利用一种非PVC复合膜储液软袋渗漏检测的实验装置对同一批次、 规格相同的300个样品进行实验, 对完好样品和渗漏样品的实验数据进行正态拟合, 用数学统计的方法对合格样品的压降数据分布情况进行分析。结果 在受相同压力的情况下, 完好样品的压力下降小于渗漏样品的压力下降。结论 在保压期间, 如果样本压力下降值在 11.31~34.68 N, 可以判断出样品为合格样品, 否则为渗漏样品。
英文摘要:
      This work aimed to study the detection method for on-line leakage detection system of non-PVC soft bag, and to propose the judgment criterion for reasonable detection of soft bag leakage. Theoretical analysis was conducted for the pressure change of the samples under external pressure, and an experimental device for leakage detection of non-PVA composite film soft bag was used to test 300 samples of the same batch and specification. Then normal fitting of the experimental data of the intact samples and leaking samples was conducted, and the pressure drop data distribution of the qualified samples was analyzed using mathematical statistic method. The result showed that the pressure drop of intact samples was less than that of leaking samples under the same pressure. The criterion for leakage detection was: the tested soft bag was qualified if its decreased pressure was between 11.31 N and 34.68 N during the dwell time, otherwise, the soft bag was leaking.
