Always check whether the equipment for cooling circulating water is running normally and whether the cooling effect is normal; adding substances that can increase the concentration of the saponification liquid in the sealed chamber at certain intervals, which can change the content of the saponification liquid in the cooling water and ensure that the monofilament can be in the guide wheel. Regularly check whether the water pressure of the circulating water is normal, and constantly change the pressure and water volume of the cooling water entering the sealed chamber according to the change of the water pressure during production.
