Ultrasonic cleaning machines are becoming more and more common in our lives. Cleaning machines are no longer only available in industrial areas. Cleaning machines have been developed around us. Today we will talk about the application of ultrasonic cleaning machine in phosphating treatment and coating treatment. After the research and practice of ultrasonic cleaning machine technology in phosphating treatment in recent years, it is improving the quality of product spraying and preventing the rust of painted parts. In terms of aspects, good results have been achieved. The general traditional process is degreasing, water washing, hydrochloric acid descaling, water washing, neutralization, water washing, surface conditioning, water washing, phosphating, water washing, and drying. The biggest disadvantage of this process is that the residual acid after pickling and rust removal of complex structural parts is difficult to clean. Especially after the phosphating of the welding assembly, the residual liquid contained in the cracks affects the processing of the subsequent process. After the workpiece is sprayed, the rust phenomenon occurs along the nip and the coating surface is damaged. Seriously affect the appearance and internal quality of the product. Such as motorcycle wheels, fuel tank, frame, anti-theft door, etc.


Ultrasonic cleaning machine rinsing is that the liquid that penetrates into the welding gap in the process of degreasing, anti-rust, water washing, conditioning, phosphating and other processes is difficult to discharge, and the water washing cannot be completely cleaned, and the inclusions are extremely hot and humid. It is easy to cause the workpiece to yellow and rust. If these residual liquids cannot be completely dried in the drying process, and then the powder is sprayed and dried at high temperature, the residual liquid will seep and weld due to the effect of thermal expansion, affecting the combination of the coating and the metal surface, causing the coating adhesion to decline or even Break away.


Ultrasonic washing machines are also used in the automotive industry, wind energy industry, aerospace industry, hydraulic industry, etc. Durr has achieved a leading position in these industries. Durr Group includes cleaning, finishing, painting, balancing and other aspects to provide customers with auxiliary installation of finishing strip production lines.
