无铅阴极电泳涂料的应用试验

为满足日益严格的环保法规和适应人类社会和谐、可持续发展的要求，开展了用无铅阴极电泳涂料LB-20LF置换含铅阴极电泳涂料HB-2000LB的试验工作。介绍了LB-20LF涂料的主要技术特征、试验室小试情况和结果，以此为基础，在生产线上成功实现了由HB-2000LB向LB-20LF的过渡和转换。还简要介绍了有关的、其他方面的如设备、工艺参数管理的改进等。试验结果表明，使用LB-20LF可提高涂膜的光泽和膜厚均匀性、改善了工件袋部的涂覆状况，可全面提高车体电泳涂层的质量。

Application Experiments of Lead-Free Electrophoretic Coatings

In order to satisfy increasingly strict environmental protection rules, to meet the requirement of harmonious and sustainable development of human society. Experiments were conducted to replace leaded HB-2000LB cathode electrophoretic coatings with lead-free LB-20LF cathode electrophoretic coatings. The features of LB-20LF coatings and experimental results are presented in this paper. The transition and transformation from HB-2000LB to LB-20LF in the production line has been successfully realized. The corresponding improvement on equipment and processing organization are introduced as well. Experimental results show that applying LB-20LF can obtain a uniform film with a high polish and improve the quality of electrophoretic coatings.
