【摘要】:目的探究改进后的红外传感器法设备对包装材料透湿性测试的影响及应用性能的提升效果。方法改进设备控温技术及夹样装置,保证试验过程温度稳定,可同时测试薄膜/片材、容器类试样,以基础方法——杯式法设备测试为参考,并分别采用改进前后的红外传感器法设备依次测试1.2 mm皮革、25μm PET薄膜、230μm太阳能背板片材、20μm PP薄膜、100μm PET/AI/PA/CPP与12μm VMPET薄膜这6种不同级别透湿性材料,分别在温度为23℃、相对湿度为90%与温度为38℃、相对湿度为90%这2种试验条件下的水蒸气透过率。结果改进后红外传感器法与杯式法设备在试验时引入的相对不确定度基本相同,与改进前设备相比,改进后红外传感器法设备的不确定度、与杯式法测试值间的相对偏差,以及各组数据间相对偏差与相对标准偏差均得到了降低。结论改进后红外传感器法设备测试不同性能包装材料水蒸气透过率的可靠性、准确性、重复性、稳定性均有提高。
[Abstract]:Objective to explore the effect of the improved infrared sensor equipment on the moisture permeability test of packaging materials. Methods to improve the equipment temperature control technology and sample clamping device, to ensure the stability of the temperature during the test process, and to test the film / sheet materials and container samples at the same time, with the reference of the basic method-cup type equipment test. The modified infrared sensor equipment was used to measure 1.2 mm leather and 25 渭 m PET thin film and 230 渭 m solar energy backboard material respectively. The six kinds of moisture permeable materials of 100 渭 m PET / PA / CPP and 12 渭 m VMPET films were measured at 23 鈩,
