Embodiment Construction
[0011] At first, referring to shown in Fig. 1, the present invention mainly comprises the following steps:
[0012] A. Ultrasonic degreasing: it puts aluminum products in an ultrasonic environment (the ultrasonic environment can be an ultrasonic vibration tank), immerses them in a degreasing agent, and uses ultrasonic vibration to degrease aluminum products. The dirt and grease on the surface are removed. The degreasing agent is mainly low-alkaline and will not corrode the surface of aluminum products. It has strong cleaning performance and less foam.
[0013] B. Soaking and washing: Put the aluminum product in a washing environment (the washing environment can be a washing tank), and use water to clean the surface of the aluminum product to remove degreaser and other liquid medicines.
[0014] C. Zinc replacement: put the aluminum product into the zinc agent again, so that the surface of the aluminum product is attached with a zinc alloy film, which can be soaked at room temp...
