In the field of the electroplating industry, the application of ultrasonic cleaning technology is imperative
Most people who engage in electroplating industries know that electroplating is depositing metal or alloys on the surface of the plating surface using electrolysis processes to form a surface treatment technique of a metal plating layer. It is certain to harm humans and the environment, such as electroplating wastewater. This has a big impact on the environment. And long-term investigators may have skin diseases, pharyngitis, and other diseases. Now some electroplating process uses non-ribbon chemical raw materials. The chemical material is brought into the plating layer in the electroplating. It will directly affect the user's body. So how do you prevent it?
Workers should wear rubber or plastic gloves, and wear an anti-acid mask, and protective glasses. The workwear should be changed the cleaned all the time. After work, you can bathe and clean your body. Use the ultrasonic cleaning equipment as much as possible in daily work. People engaged in electroplating industries understand that it has high requirements for the surface cleanliness of the workpiece. The ultrasonic cleaning machine principle is a high-frequency oscillation signal emitted by an ultrasonic generator. Then convert to a high-frequency mechanical oscillation through a transducer and propagate into the medium. The ultrasonic waves in the cleaning solvent are disturbed in the cleaning liquid. This flows from tens of thousands of microbubbles flowing through liquid flow. The micro-bubble (cavitation nucleus) present in the liquid is vibrated under the action of the sound field. When the sound pressure reaches a certain value, the bubble grows rapidly and then suddenly closed. A shock wave is generated when the bubble is closed. A thousand atmospheric pressure is generated around it. This can destroy insoluble dirt and disperse them in the cleaning liquid. When the group particles are wrapped in oil, the oil is emulsified, and the solid particles are detached. This achieves the purpose of cleaning the surface of the workpiece. Due to the inherent penetration of ultrasonic waves, it is possible to clean an object that is complex and specific to its shape. There is a good cleaning effect on small holes and gaps. It is best to clean the object with a non-sound absorbing or small sound absorbing coefficient.
It can be seen that the ultrasonic cleaning machine occupies a place in the field of the electroplating industry. Let's take some points:
1. Wash the surface of the polishing paste.
Under normal circumstances, polishing cream often uses paraffin to engage. The paraffin is large, high melting, and it is solid-state at room temperature. It is a substance that is more difficult to clean. The traditional approach is to use organic solvent cleaning or high-temperature alkaline water to boil. A water-based cleaning agent can be used with ultrasonic cleaning. Under medium temperature conditions, the surface of the workpiece was thoroughly cleaned in a few minutes. The commonly used process is 1 soaking; 2 ultrasonic cleaning; 3 water (water) rinsing.
2. Cold rolled steel sheet has oil and is less rusty on the surface.
There is generally oil, pollution or small rust on the surface of the cold-rolled steel sheet. It is easy to wash and clean. However, after general cleaning, the surface of the workpiece remains a very thin snuff bit. It will affect the quality of subsequent processing. Sometimes it will have to use strong acid soaking methods to remove this layer of fluffy. If you use ultrasonic cleaning and appropriate cleaning fluid, you can easily and quickly clean the surface of the workpiece. And make the surface of the workpiece have high activity. Sometimes, it can be exempt from electroplating acid soaking.
3. The workpiece with oxidized skin and yellow rust on the surface.
The traditional method is to clean with hydrochloric acid or sulfuric acid. If ultrasonic integrated processing techniques are used, oil, rust, and rust on the surface of the workpiece can be simultaneously removed within a few minutes. And avoid the hydrogen crispy problems due to strong acid cleaning.
In the above, the ultrasonic cleaning machine technology can be used to clean the oil. It can be replaced by electrically release oil. It is also possible to remove rust and oxidative skin of carbon steel and low alloy steel surface. The application of ultrasonic cleaning techniques can make many traditional cleaning processes simplify and greatly increase cleaning quality and productivity. In particular, workpieces having a higher shape complicated and adjacent corners are superior. Ultrasonic cleaning techniques can also replace strong acids and strong bases in a large range. A greatly reduces the pollution of the environment and improves the workers' labor environment. It also reduces labor intensity and contributes to protecting the ecological environment.
It has been proved that the ultrasonic cleaning equipment can replace the original acid-base treatment station of the electroplating line successfully. This makes the quality and output of electroplated parts more improved than the original. And improved the production environment, and achieved good economic and social benefits. At the same time, the blue whale team can sincerely help you design custom-made ultrasonic cleaning equipment according to the size and quantity of different items.
