Embodiment Construction
[0020] The temperature control and concentration control of the degreasing liquid are completed in the lower tank. After the pump and coarse filtration, the nozzle that hits the upper tank is sprayed to the front surface of the aluminum plate base through the upper nozzle hole, and flows into the small outlet end along the slope of the aluminum plate front After filling the small tank, it overflows to the upper tank for degreasing, flows back to the lower tank through the return pipe of the upper tank, and completes a tank liquid cycle; the front of the aluminum plate uses the spray method and the outlet end immersion method, due to the long reaction time , To be fully corroded; the back of the aluminum plate is only immersed at the outlet end. Due to the immersion method, the corrosion is uniform and the time is short, so the back of the aluminum plate is clean and maintains metallic luster.
