我厂先后试制成功了单层、双层、三层及合股的潜水线(见图),初步解决了生产农用潜水电机所需要的导线问题。潜水线生产工艺涂聚乙烯和尼龙所用的漆包线和一般电机用的漆包线相同,我厂用的漆包线涂的是缩醛漆,漆层单边厚度为0.05毫米。1.材料烘干先将聚乙烯放在能抽真空且带鼓风的恒温(40～50℃)箱中烘干4小时;尼龙1010放在同前的恒温(80～100℃)箱中烘干12小时。鼓风能保证箱内各处温度均匀一致,抽真空可使烘干的料不变颜色,否则会变黄。总的要求是排除水分。
Our factory has succeeded in trial production of single, double, triple and ply diving line (see photo), initially solved the production of agricultural submersible motor required wire problem. Diving line production process coated with polyethylene and nylon used enameled wire and the general motor with the same enameled wire, my factory enameled wire coated with acetal paint, paint unilateral thickness of 0.05 mm. 1. Material drying Polyethylene is first placed in a vacuum oven with a blast of air (40 ~ 50 ℃) box drying 4 hours; nylon 1010 on the same front of the constant temperature (80 ~ 100 ℃) box oven Dry for 12 hours. Blast can ensure that the temperature inside the box uniform, vacuum drying materials can make the same color, otherwise it will turn yellow. The general requirement is to exclude moisture.
