摘要
以漆包工艺中的涂漆与烘焙两个重要环节作为研究对象,研究了聚氨酯底漆和聚酰胺自粘漆的不同涂漆与烘焙工艺对漆包线性能的影响,总结得出漆最适宜涂制的线型规格为0.350 mm,最佳的涂漆与烘焙工艺为:底漆涂线10道,面漆涂线3道,采用单炉膛固化,行线速度54 m/min,炉温曲线310℃/370℃/390℃,交换风速560 r/min,排废速度300 r/min。所生产的自粘性直焊漆包线各项技术指标均满足用户需求,热性能数据达到直焊性180级耐热等级的要求。
Two important processes in enameling process, painting and curing, were used as research object to study the effect of different painting and curing process of polyurethane primer and ployamide self-adhesive paint on the performance of enameled wire. The results show that the most suitable wire dimension is 0.350mm, and the best painting and curing processes are as follows： 10 primers and 3 finish coats, single-furnace curing, 54rn/min of wire speed, 310℃/370 ℃/390 ℃ of furnace temperature, 560r/ min of switching wind speed and 300r/min of waste discharge speed. The technical index of the self-adhesive direct-welding enameled wire can meet the users＇ requirements, and the thermal property can meet the requirements for grade 180 heat resistance.
