How to save water in spraying production line? In the process design of part of the spraying production line , after degreasing and phosphating, water replenishment treatment is performed separately, and fresh industrial water is not directly added to achieve the purpose of further water saving. At present, this water-saving method has been widely used in coating production lines. Reverse treatment of overflow water cleaning. After degreasing or phosphating, it is necessary to wash with water several times to clean the chemicals attached to the surface of the workpiece. In order to save water, the pre-treatment washing process of the spraying production line is designed as two water-saving units, so that the washing water is discharged from the previous process tanks separately into a unit discharge, and the rear washing water supply is used, and the front washing tank is overflowed for water supply in sequence. , And finally discharged into the trench to improve the utiliz...
