摘要

利用超声速粘接机将高性能驻极体过滤介质粘接在多层驻极体非织造布上。此时会产生针孔,过滤效率下降。针对针孔的检测,讨论了利用CCD相机捕捉通过样品针孔穿透的光的测量方法。提高针孔与其他针孔之间的亮度SN比具有重要意义。通过对光源与样品之间的距离、光的狭缝间隙、偏振光膜的设置等因素的讨论,显示出改善的迹象。

Pinhole Detection Method of an Electret Filtering Media with High Performance
High performance electret filter media are bonded a few laminated electret nonwoven fabrics by the supersonic bonding machine.At that time, pinholes are occured, the filtering efficiency goes down. On account of detecting the pinholes, we are discussed the measuring method used CCD camera catching light penetrated through pinholes of the sample. It is important to improve the SN ratio of luminosity between pinholes and others. It was shown signs of improvement by discussed with the distance between light source and sample, slit clearance of light, and setting of polarized light film.
