The reason for the oxidation of the surface of the monofilament drawn by the inverted wire drawing machine
1. The temperature of the cooling water in the sealed chamber is too high, exceeding 40°C, so the sealed chamber cannot achieve the required cooling effect on the single wire, resulting in the temperature of the single wire still high after annealing, and encountering oxygen in the air at high temperature and oxidation.
2. The saponified liquid content of the cooling liquid in the sealing chamber is not enough, which will increase the friction between the monofilament and each guide wheel, and then increase the temperature of the monofilament again, causing the surface of the monofilament to oxidize.
3. The water pressure and water volume of the cooling water in the sealed chamber are not enough, so that the monofilament cannot achieve a satisfactory cooling effect.
