Problems solved by technology

[0002] According to the current general aluminum products, the surface gloss is not good, and it is easy to rust. Therefore, a nickel layer is usually electroplated on the surface of aluminum products to make it have better metallic luster and anti-rust advantages, but Due to the known electroplating method of aluminum products, the steps are mainly to use ultrasonic waves to degrease, then soak and wash the aluminum products, then put the aluminum products in the zinc agent for zinc replacement, and then soak and wash them directly on the surface of the aluminum products Electroplating has a nickel layer; however, such an electroplating method is likely to cause poor adhesion of the electroplated nickel layer on the surface of the aluminum product, resulting in blisters on the surface, resulting in poor electroplating quality and increased defect rates. , and then increase the manufacturing cost, so the electroplating nickel layer method of conventional aluminum products is not perfect enough

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...
