碱锰电池尼龙密封圈爆破压力测试影响因素探究

通过对碱锰电池尼龙密封圈爆破压力测试环境、测试方法等因素的选择与改变，研究了密封圈测试前热处理温度、热处理时间、测试前晾晒时间以及测试环境温度、湿度等因素对尼龙密封圈爆破压力测试值的影响。研究结果表明，热处理温度越高，热处理时间越长，测试值越低；晾晒时间越长，测试值越高；测试温度越高，测试值越低；测试湿度越高，测试值越低。对各因素产生的结果进一步研究，并结合实验发现，各因素的变化对尼龙材料的内部水分造成了影响，也导致测试值的变化。

Study on the influence factors in the test of burst pressure of nylon gasket for alkaline Zn-MnO2 battery

With the changes of test environment and test methods for burst pressure of alkaline manganese battery nylon gasket,the influences of the heat treatment temperature,heat treat-ment time,drying time before test and test environment factors such as temperature or humidity on the test results are studied.Results show that the higher the heat treatment temperature and the longer the heat treatment time,the lower the test values;the longer the drying time,the higher the test values;the higher the testing temperature,the lower the test values;the higher the test humidity,the lower the test values.After the further study on the effects of various fac-tors and combined with the experiments’results,it is found that the change of the factors would affect the internal moisture of the nylon material,and then lead to the change of test values.
