Using the cavitation effect produced by ultrasonic in the liquid, the oil stains attached to the surface of the workpiece can be cleaned, and with appropriate cleaning agent, the surface of the workpiece can be quickly processed with high cleanliness.

Electroplating process, the workpiece surface cleanliness requirements are higher, and ultrasonic cleaning technology is an ideal technology to achieve this requirement. Using ultrasonic cleaning technology, can replace solvent cleaning oil; Can replace the electric lifting oil; It can replace strong acid etching to remove rust and scale on the surface of carbon steel and low alloy steel. The application of ultrasonic cleaning technology can simplify many traditional cleaning processes, and greatly improve cleaning quality and production efficiency. Especially for those more complex shape, higher requirements of the edge of the workpiece is more advantageous. Using ultrasonic cleaning technology, can also replace the role of strong acid and alkali in a large range, greatly reduce the pollution of the environment, and improve the labor environment of workers, reduce labor intensity, to protect the ecological environment, make a contribution.

Brief introduction of ultrasonic cleaning process for several common workpiece surface conditions:

1, polishing parts surface polishing paste cleaning.

Under normal circumstances, polishing paste is often used paraffin blending, paraffin molecular weight is large, high melting point, solid state at room temperature, is difficult to clean the substance, the traditional method is to use organic solvent cleaning or high temperature alkali water boiling wash has many drawbacks. The use of ultrasonic cleaning can use water-based cleaning agent, under the condition of moderate temperature, the surface of the workpiece will be thoroughly cleaned in a few minutes, the commonly used process is: ① immersion →② ultrasonic cleaning →③ clean water (water) rinse.

2. Cold rolled steel plate with oil and a little rust on the surface.

Cold rolled steel plate surface generally has oil, dirt or a small amount of rust, it is easier to clean, but after the general method of cleaning, the workpiece surface remains a very thin layer of floating ash, affecting the quality of subsequent processing, sometimes have to use strong acid immersion method to remove this layer of floating ash. And the use of ultrasonic cleaning and appropriate cleaning liquid, can easily and quickly realize the workpiece surface thoroughly clean, and make the workpiece surface has a high activity, sometimes even can be removed before plating acid leaching activation process.

3, the surface of the workpiece with oxide skin and yellow rust.

The traditional method is to use hydrochloric acid or sulfuric acid immersion cleaning. Such as the use of ultrasonic comprehensive treatment technology, can quickly remove oil and rust on the surface of the workpiece in a few minutes, and avoid the hydrogen embrittlement problem caused by strong acid cleaning.
