一.浸涂系统的设备各类磷酸盐涂层(锌的、锰的和铁的)的浸涂系统应包括: a)一定量的槽; b)温度与液面的控制装置; c)溢流与排放系统; d)蒸气排出系统; e)原材料存放与输送装置。在用转鼓装载零件的时候,每个槽上都应有驱动转鼓的装置,把转鼓和零件浸入溶液中,并以将近4r/min的速度转动。磷化槽磷化槽通常是用6mm左右厚的钢板(1/4in)制成的。图1表示一个用磷酸盐溶液浸涂小零件的槽与转鼓。在一般的操作条件下,磷酸锌溶液所用的低碳钢槽,其使用
I. Equipment for dip coating systems Dip coating systems for various types of phosphate coatings (zinc, manganese and iron) shall include: a) a quantity of tank; b) temperature and level control means; c) Flow and discharge system; d) steam discharge system; e) raw material storage and delivery device. When loading parts with a drum, there should be a means of driving the drum in each groove, immersing the drum and parts in solution and rotating at a speed of approximately 4r / min. Phosphate tank Phosphate tank is usually about 6mm thick steel (1 / 4in) made. Figure 1 shows a tank and drum with a small solution of dip phosphate solution. In general operating conditions, zinc phosphate solution used in low-carbon steel tank, its use
