The temperature of the cooling water in the sealed chamber is too high ; the saponification liquid content of the cooling liquid in the sealed chamber is not enough, which will increase the friction between the monofilament and the guide wheels , and then the temperature of the monofilament will rise again, causing the surface of the monofilament to oxidize . 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. Frequently check whether the equipment for cooling circulating water is operating normally and whether the cooling effect is normal ; add substances that can increase the concentration of the saponification liquid in the sealed chamber after a certain period of time, so that the content of the saponification liquid in the cooling water can be changed to ensure that the monofilament can be guided in the The wheel runs normally ; regularly check whether the water pressure of the circulating water is normal, and constantly change the pressure and volume of the cooling water entering the sealed chamber according to the change of the water pressure during production.
