摘　　要：为了考察环境条件对爆珠力学性能的影响,通过测试不同环境条件下爆珠的质量、压破强度、压破形变率和弹性指数,提出了爆珠样品的适宜环境条件。结果表明:①爆珠和爆珠滤棒在"温度(22±1)℃、相对湿度(60±2)%"的环境下调节48 h能够达到温湿度平衡。②爆珠的压破强度、压破形变率和弹性指数在40%~60%相对湿度范围和10~40℃温度范围内略有差异,但差异的程度与样品差异有较大关系。极限温度条件(低于10℃,高于40℃)对爆珠的力学性能有较大的影响,低温冷冻后爆珠的力学性能不可恢复。③爆珠的力学性能在爆珠生产、爆珠滤棒加工和爆珠卷烟加工各环节的温湿度条件下均没有较大差异。In order to investigate possible effects of environmental conditions on the mechanical properties of breakable capsules for cigarette filters,the weight,crushing strength,crushing deformation rate and elasticity index of breakable capsules were tested under different environments,and suitable environmental conditions for breakable capsule samples were proposed.The results indicated that:1)After adjusting for 48 h in the atmosphere of temperature(22±1)℃and relative humidity(R.H.,60±2)%,the weights of capsules and filters with single capsule were constant.2)The crushing strength,crushing deformation rate and elasticity index of breakable capsules were slightly different within 40%-60%R.H.and 10-40℃,and the degree of difference greatly correlated to the samples.The extreme temperature(lower than 10℃or higher than 40℃)had a significant influence on the mechanical properties of the tested capsules,and the mechanical properties could not recover after a low temperature freezing.3)There was no significant difference in the mechanical properties of breakable capsules under the temperature and humidity conditions in the production processes of breakable capsules,filter rods and cigarettes.
