Brief introduction to the ultrasonic cleaning process for several common workpiece surface conditions:
1. A workpiece with oxide scale and yellow rust on the surface.
The traditional method is to wash with hydrochloric acid or sulfuric acid. If ultrasonic cleaning treatment technology is adopted, the oil and rust on the surface of the workpiece can be removed at the same time in a few minutes, and the hydrogen embrittlement problem accompanying the strong acid cleaning can be avoided.
In summary, the ultrasonic cleaning machine technology will have a wide application prospect in the electroplating and other industries. In recent years, many electroplating manufacturers have adopted ultrasonic cleaning technology equipment instead of the original acid-base treatment station of electroplating line, which has made the quality and output of electroplating parts more improved than before, improved the production environment and achieved good economy. Benefits and social benefits. All electroplating manufacturers are welcome to Guangzhou Kejin Ultrasonic Equipment Factory to discuss cooperation, we will be happy to serve you. To help you design a reasonable and optimized ultrasonic cleaning line 2, cleaning of the polishing surface polishing paste.
Under normal circumstances, polishing paste is often blended with paraffin wax. Paraffin has a high molecular weight, a high melting point, and is solid at room temperature. It is a difficult material to clean. The traditional method is to use organic solvent cleaning or high-temperature alkaline water to boil. Ultrasonic cleaning can use water-based cleaning agent to thoroughly clean the surface of the workpiece in a few minutes under medium temperature conditions. The common process is: 1 soak 2 ultrasonic cleaning 3 clean water (clean water) rinse.
3. Cold-rolled steel sheets with oil and a small amount of rust on the surface.
The surface of the cold-rolled steel sheet generally has oil, dirt or a small amount of rust. It is easy to wash it. However, after cleaning by the general method, a very fine floating ash remains on the surface of the workpiece, which affects the subsequent processing quality. Sometimes it is necessary to use strong acid. Soak the way to remove this layer of floating ash. Ultrasonic cleaning and proper cleaning solution can quickly and thoroughly clean the surface of the workpiece and make the surface of the workpiece highly active, sometimes eliminating the need for acid leaching before plating.
The mechanism of ultrasonic cleaning mainly has the following aspects: a strong shock wave is generated when the cavitation bubble is broken, and a part of the dirt layer is peeled off, dispersed, emulsified, and peeled off under the action of the shock wave. Because of the bubbles generated by the cavitation phenomenon, the gap between the dirt layer formed by the impact and the surface layer and the gap penetrates, because the small bubble and the sound pressure expand and contract simultaneously, the physical force such as peeling repeatedly acts on the dirt layer, the dirt The layers are peeled off and the bubbles continue to penetrate inward until the dirt layer is completely stripped. This is the secondary effect of cavitation. The impact of ultrasonic vibration of cleaning fluid on dirt in ultrasonic cleaning. Ultrasonic accelerated chemical cleaning agent dissolves the dirt, chemical and physical forces combine to accelerate the cleaning process.
Ultrasonic cleaning machine thoroughly cleans plating equipment
The ultrasonic cleaning machine adopts the principle of ultrasonic cleaning, which can achieve the overall clean cleaning effect of the object. Especially for the deep hole, blind hole, and concave groove cleaning, it is the ideal equipment of Zui, and does not affect the material and precision of any object. At the same time, in the experiments of biochemistry, physics, chemistry, medicine, scientific research and colleges and universities, it can be used for extraction, degassing, mixing, cell pulverization and nano-decomposition. The electroplating process requires high surface cleanliness, and ultrasonic cleaning technology is the ideal technology to meet this requirement. Ultrasonic cleaning machine technology can replace solvent cleaning oil; can replace electric de-oil; can replace strong acid etching to remove rust and scale on carbon steel and low alloy steel surface. The application of ultrasonic cleaning technology can simplify many traditional cleaning processes and greatly improve cleaning quality and production efficiency. Especially for those workpieces with complex shapes and high corner requirements. Ultrasonic cleaning technology can also replace the role of strong acid and alkali in a wide range, greatly reduce pollution to the environment, improve the labor environment of workers, reduce labor intensity, and contribute to the protection of the ecological environment.
