Workpieces with oxide scale and yellow rust on the surface of vacuum silver plating

If the ultrasonic comprehensive treatment technology is adopted, the traditional strong acid soaking can be changed to weak acid cleaning, which can quickly remove oil and rust on the surface of the workpiece, and at the same time avoid the hydrogen embrittlement problem caused by strong acid cleaning.

In recent years, many vacuum coating manufacturers have adopted ultrasonic cleaning technology and equipment to replace the original acid-base treatment station of the vacuum coating line. Benefit and Social Benefit

Workpieces with oil and floating rust on the surface of vacuum silver plating

For oil stains or floating rust on the surface of the workpiece, the advantages of using the ultrasonic cleaning process are that it can not only quickly clean the surface of the workpiece, but also make the surface of the workpiece have high activity, which is unmatched by the traditional strong acid soaking process.

Cleaning of polishing paste on the surface of vacuum silver-plated polishing parts

Under normal circumstances, polishing paste is often blended with paraffin wax. Paraffin wax has a large molecular weight, a high melting point, and is solid at room temperature. For better results, use a water-based cleaning agent to quickly and thoroughly clean the surface of the workpiece within a few minutes under medium temperature conditions. The usual process is: ① soaking → ② ultrasonic cleaning → ③ clear water (clean water) rinsing. Or ① ultrasonic rough washing → ② ultrasonic fine washing → ③ clear water (purified water) rinsing.

Advantages of vacuum silver plating using ultrasonic cleaning technology

The vacuum coating process has high requirements on the cleanliness of the surface of the workpiece. The application of ultrasonic cleaning technology can simplify many traditional cleaning processes, such as replacing electrolytic degreasing, replacing solvent degreasing, replacing strong acid rust and oxide skin, and greatly reducing the cost of cleaning. Improve cleaning quality and productivity. Utilizing the ubiquitous characteristics of cavitation bubbles, it is more advantageous for those workpieces with complex shapes and high edge and corner requirements. The use of ultrasonic cleaning technology can also replace the role of strong acid and alkali in a large range, reduce environmental pollution, improve the working environment, and reduce labor intensity.
