By using the ultrasonic cavitation effect in the liquid, the oil stain on the surface of the workpiece can be cleaned, and the cleaning of the surface of the workpiece can be realized quickly with the appropriate cleaning agent. Electroplating process, the workpiece surface cleanliness requirements, and ultrasonic cleaning technology is able to meet the requirements of the ideal technology. The use of ultrasonic cleaning technology, can replace the solvent to clean the oil can be replaced by electrolytic degreasing; can replace the strong acid erosion removal of carbon steel and low alloy steel surface rust and oxidation. The application of ultrasonic cleaning technology can simplify many traditional cleaning processes, and greatly improve the cleaning quality and production efficiency. Especially for those more complex shape, the edge of the workpiece is more demanding. The use of ultrasonic cleaning technology, but also can replace the acid and alkali in a large range of effects, greatly reducing the pollution and the environment, and improve the working environment, reduce labor intensity, to protect the ecological environment and make a contribution. For several common surface conditions of the workpiece, the use of ultrasonic cleaning process brief introduction: 1, polishing the surface of the cleaning paste. In general, polishing paste is often used paraffin wax blending, high molecular weight, high melting point, room temperature in solid state, it is difficult to clean the material, the traditional method is to use organic solvent cleaning or high temperature alkali washing boiled many evils. You can use a water-based cleaning agent used in ultrasonic cleaning, medium temperature, a few minutes will thoroughly clean the surface of the workpiece, the commonly used process is: soaking, the ultrasonic cleaning, the water (water) rinse. 2, the surface of oil and a small amount of cold rolled steel. Have oil, dirt or small rust surface of cold-rolled steel plate, should be cleaned easily, but the general method of cleaning, the surface of the workpiece is still a very thin layer of dirt, affect the machining quality, sometimes have to use acid soaking to remove this layer of dust. The ultrasonic cleaning and proper cleaning liquid can be used to clean the surface of the workpiece conveniently and quickly, and make the surface of the workpiece have higher activity. 3, the surface of the oxide and yellow rust. The traditional approach is to use hydrochloric acid or sulfuric acid immersion cleaning. Such as the use of ultrasonic integrated treatment technology, can quickly remove the surface of the workpiece in a few minutes of oil, rust, and to avoid the strong acid cleaning due to hydrogen embrittlement. Ultrasonic cleaning technology will be widely used in electroplating industry. In recent years, many manufacturers have adopted electroplating transicom Boda ultrasonic cleaning technology and equipment, the success of alternative alkali treatment station original electroplating line, the plating quality and yield than the original have greatly improved, and improve the production environment, and achieved good economic and social benefits.
