摘要
为研究防静电服的摩擦带电状况,利用国标GB 12014-2009《防静电服》中规定的滚筒摩擦法使防静电服与标准布摩擦产生静电积累电荷,并通过法拉第筒感应收集,从测试可靠性角度探讨在相同和不同的空气相对湿度下收集的电荷量大小,并且考察滚筒摩擦时间对静电积累电荷的影响.结果表明：100次滚筒摩擦实验后,电荷量的分布范围为0.10～0.40 μC,比国标中的判断标准（0.20 μC）显得发散,50次以上摩擦测试取平均值可以得到相对稳定的测量结果;电荷量不随着单次摩擦时间的延长而增加,随着摩擦次数增加,电荷量均值有减小的趋势;在60％的电荷分布区域（0.19 ～0.25 μC）上,体现相对湿度增大,电荷量减小的趋势,但这种趋势从总体的测试电荷量分布来看并不明显.
In order to study the electric charges produced by friction on the anti-static clothing, an experiment was carried out in accordance with China National Standard GB 12014--2009 ＂Anti-static Clothing＂ by using drum friction method to measure the accumulated charges on the anti-static clothing during friction against a standard test cloth on the drum, and the induction collection of the charges were performed using Faraday cage and related devices. The collected charge quantity as affected by the relative humidity （RH） of air was investigated with a viewpoint of test reliability, along with the impact of friction duration on the static charge accumulation. The results showed： the distribution of electric charges is between 0. 10μC and 0.40 μC after 100 cycles of friction, which looks more dispersive than that （0.2μC） in the GB 12014--2009. The average value of the result of more than 50 cycles of friction test is more reliable. As each friction time extends, the magnitude of electric charges does not increase. However, the mean value of electric charges slightly decreases as the friction cycle increases. It is demonstrated that electric charges decrease as the RH increases in the 60% distribution zone （0.19 - 0.25 μC）. But the trend is not obvious for overall charge distribution.
