摘要/Abstract

摘要： 本文通过纤维压缩装置和一系列单侧电极系统地实验研究影响单侧极板电阻测试的因素，以期望其有助于毛纤维回潮率测试仪的设计。通过实验分析发现：毛纤维集合体测试深度是有限的，随着毛散纤维集合体厚度的增加测试电阻减少是有限的；测试电阻随着单侧极板间距的减少而减小，极板间距越小时测试电阻增幅减小；电阻随着极板面积的增大而减少，其增幅随极板面积的增大而减缓；测试电阻随着毛散纤维集合体密度增加而减少；测试深度随着电压的增大而增大，平行极板的电压选择应尽量的大但不能超过毛散纤维的局部击穿电压。

Abstract: Fiber compression device and a serial of one-side electrodes were used to study the factors affecting the electrodes resistance testing, and it’s hopeful to improve wool fiber moisture tester’s design. Experiment results show that the measuring depth is limited and the falling of measuring resistance is finite with the increasing of thickness of random wool fiber assembly. The resistance decreases with the decrease of the distance between electrodes, with the increasing of separation distance of one-side electrodes the variation of resistance increase. The resistance decreases with the increase of electrode area, and with the increase of area, variation of resistance slows down. The resistance decreases with the increase of wool fiber volume density. The measuring depth increases with the increase of applied voltage. The suitable voltage of one-side electrodes is bigger but no more than wool fiber’s local breakdown voltage.

Key words: electrical resistance, one-side parallel electrodes, wool fiber, on-line measurement
