秦岭公司二厂生产的某型电机,换向极绕组一直采用溶剂型绝缘漆工艺,虽经两次涂漆工序,但在绕组棱角边缘处几乎没有漆层,难以解决绝缘电阻低的缺点,致使产品一度成批回厂返修。为此,在公司各级领导的重视与关怀下,成立了攻关试验小组。攻关小组根据湖南电线厂电泳涂复聚酯绝缘漆制造大截面QZ漆包扁线的经验,在兴平油漆厂的协助下终于制成了水溶性高强度聚酯绝缘电泳漆,并掌握了在换向极绕组上电泳涂漆工艺。电泳涂漆试件
Qinling Company Plant a certain type of motor, the commutation pole winding has been using solvent-based insulating paint technology, although after two painting process, but the edge of the winding edges almost no paint, it is difficult to solve the shortcomings of low insulation resistance, resulting in Once the product back to the factory repair. To this end, the company leaders at all levels of attention and care, the establishment of a key task force. Research team based on the Hunan Electric Plant electrophoretic coated polyester insulating paint manufacturing large cross-section of QZ enameled flat wire experience in the Xingping paint factory finally made a water-soluble high-strength polyester insulation electrophoretic paint, and mastered the commutation Very winding electrophoretic coating process. Electrophoretic paint test pieces
