oneThe temperature of the cooling water in the sealed chamber is too high, exceedingfortyAt a temperature of ℃, the sealed chamber cannot provide the required cooling effect on the monofilament, resulting in the monofilament remaining at a high temperature after annealing and oxidizing when exposed to oxygen in the air at high temperatures.twoThe saponification content of the coolant in the sealed chamber is not sufficient, which will increase the friction between the monofilament and each guide wheel, thereby causing the temperature of the monofilament to rise again and forming oxidation on the surface of the monofilament.threeThe water pressure and volume of the cooling water in the sealed chamber are insufficient, preventing the single filament from achieving the desired cooling effect. Solution: Regularly check whether the cooling circulating water equipment is working properly and whether the cooling effect is normal; At a certain time in the sealed chamber, substances that can increase the concentration of saponification solution can be added, which can change the content of saponification solution in the cooling water and ensure that the monofilament can work normally on the guide wheel; Regularly check if the water pressure of the circulating water is normal, and continuously adjust the pressure and amount of cooling water entering the sealed chamber based on changes in water pressure during production.
