Application of the hottest ultrasonic cleaning tec

  • Detail

Ultrasonic cleaning technology is applied to pre-treatment of electroplating

using the cavitation effect produced by ultrasonic in the liquid, the oil stains on the surface of the workpiece can be cleaned. With appropriate cleaning agents, the surface of the workpiece can be quickly treated with high-definition cleanliness

electroplating process requires high surface cleanliness of workpiece, and ultrasonic cleaning technology is an ideal technology to meet this requirement. Ultrasonic cleaning technology can replace solvent to clean oil stains; It can replace electrolytic deoiling; It can replace strong acid etching to remove rust and oxide 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 the cleaning quality and production efficiency. Especially for those workpieces with complex shapes and high requirements for edges and corners. The use of ultrasonic cleaning technology can also replace the role of strong acids and bases in a large range. First of all, it can increase the endurance distance, greatly reduce the pollution to the environment, improve the working environment of workers, reduce labor intensity, and contribute to the protection of the ecological environment

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

1. Cleaning of polishing paste on the surface of polished parts

in general, polishing paste is often blended with paraffin. Paraffin has large molecular weight, high melting point, and is solid at room temperature. It is a substance that is difficult to clean. The traditional method is to clean with organic solvent or boil with high-temperature alkaline water. There are many disadvantages. It can be tested after fixing. If ultrasonic cleaning is adopted, water-based cleaning agent can be used. Under medium temperature conditions, the surface of the workpiece can be thoroughly cleaned within a few minutes. The common process flow is: ① soaking → ② ultrasonic cleaning → ③ rinsing with clean water (purified water)

2. Cold rolled steel sheet with oil and a small amount of rust on the surface

generally, there is oil, dirt or a small amount of rust on the surface of cold-rolled steel plate, so it is easy to clean it, but after general cleaning, there is still a very thin layer of floating ash on the surface of the workpiece, which affects the subsequent processing quality, and sometimes we have to remove this layer of floating ash by soaking in strong acid. By using ultrasonic cleaning and proper cleaning solution, the surface of the workpiece can be thoroughly cleaned easily and quickly, and the surface of the workpiece has high activity. Sometimes, it can even eliminate the acid pickling process before electroplating

3. Workpieces with oxide skin and yellow rust on the surface

the traditional method is to soak and clean with hydrochloric acid or sulfuric acid. If ultrasonic comprehensive treatment technology is adopted, the workpiece can be removed at the same time in a few minutes. 1 The new experiment records the oil and rust on the surface, and avoids the hydrogen embrittlement caused by strong acid cleaning

in conclusion, ultrasonic cleaning technology will have a wide application prospect in electroplating and other industries. In recent years, many electroplating manufacturers have successfully used Wuxi Meijie ultrasonic cleaning technology and equipment to replace the original acid-base treatment station of the electroplating line, which has greatly improved the quality and output of electroplated parts compared with the original, improved the production environment, and achieved good economic and social benefits. Welcome all users to our company to discuss cooperation, and we will serve you wholeheartedly. To help you design a reasonable and optimized electroplating pretreatment process is limited by the flow of oil source. (end)
