目的 提高日化品瓶铝箔密封性的检测准确率。方法 提出一种日化品瓶铝箔密封性检测方法。通过对铝箔密封后的日化品瓶瓶身施加压力，使瓶身产生一定的形变，基于采集施压过程中日化品瓶产生的反作用力，建立空气泄漏模型对日化品瓶铝箔密封性进行判定。设计日化品瓶铝箔密封性测试实验平台，在不同挤压行程和挤压速度下，对日化品瓶铝箔密封性进行实验。结果 将实验得到的数据代入空气泄漏数学模型后得到的泄漏面积数值与实际数值的最大误差为4.5%。结论 日化品瓶铝箔密封性检测方法操作简单、检测精确，为实际生产过程中对日化品瓶铝箔密封性检测提供了依据。

The work aims to improve the detection accuracy of aluminum foil sealability of daily chemical bottle. A method for detecting aluminum foil sealability of daily chemical bottle was proposed. Pressure was applied to daily chemical bottle sealed with aluminum foil to make it deform to a certain extent. Based on the reaction force generated by the daily chemical bottle during the process of applying pressure, an air leak mathematical model was established to judge the aluminum foil sealability of daily chemical bottle. An experimental platform for detecting aluminum foil sealability of daily chemical bottle was designed, and the aluminum foil sealability of daily chemical bottle was detected under different extrusion strokes and extrusion speed. After the data obtained from the experiment were brought into the air leak mathematical model, the maximum error between the value of the leakage area obtained and the actual value was 4.5%. The method for detecting aluminum foil sealability of daily chemical bottle is simple and accurate, which provides a basis for detecting aluminum foil sealability of daily chemical bottle in the actual production.
