1、喷淋磷化的特点和适用性喷淋磷化,主要藉助泵的作用压送磷化处理液,经管网、喷管和喷咀向工件喷淋,在工件表面形成磷化膜;从工件表面淋落下来的磷化处理液集中流向贮液箱。贮液箱容积通常为泵的每小时流量的1/30～1/20。喷淋磷化不需要将工件全部浸没在磷化处理槽内,可省却浸渍磷化所必须的、深度超过工件高度的浸渍处理槽。同时,由于工件毋需入槽和出槽,可省却悬挂输送链的升降段,从而简化了涂装作业生产线。
1, the characteristics and applicability of spray phosphating Spraying phosphating, mainly by the role of the pump pressure delivery phosphating solution, the pipe network, nozzle and nozzle spray to the workpiece to form a phosphate coating on the surface of the workpiece; from The surface of the phosphating solution pouring liquid down to the tank. The tank volume is usually 1/30 to 1/20 of the pump’s hourly flow. Spraying Phosphating eliminates the need to submerge the workpieces all in the phosphating bath, eliminating the need for immersion baths that are necessary for phosphating and have a depth that exceeds the height of the workpiece. At the same time, as the workpiece does not need to slot and slot, you can save the lifting chain hoisting section, thus simplifying the coating production line.
