FAQ 1
1. What is "cavitation"?
Cavitation is a phenomenon in which millions of tiny bubbles (or holes) rapidly form and burst in liquids. Cavitation is caused by the interaction of high and low pressure waves formed by high frequency acoustic waves (ultrasound). In the low-pressure stage, the bubbles increase little by little, while in the high-pressure stage, they are compressed and imploded.
2. How can I achieve the best ultrasonic cleaning effect?
There are many conditions that can determine the final cleaning effect, among which the most important is to choose the right cleaning fluid, the right time to clean at the right temperature, and the right size and type of ultrasonic cleaning machine.
3. Will ultrasonic cleaning damage my workpiece?
Ultrasound cleaning is safe for most workpieces. The energy generated by the implosion of thousands of bubbles per second is huge, but because the energy is concentrated in very small areas, the whole cleaning process is safe. The most cautious consideration for safety should be the choice of cleaning fluid. The potential harmfulness of cleaning fluid to the surface of some workpieces may be increased by the use of ultrasound. Ultrasound cleaning is not recommended for cat's eye, pearl, jadeite, tanzanite, malachite, emerald, lapis lazuli and coral.
4. What are "direct" and "indirect" cleaning?
Direct cleaning usually refers to the cleaning of the workpiece in a cleaning tank filled with cleaning fluid, and the workpiece is usually installed in a tray or tooling basket with holes. The limitation of direct cleaning is the need to select cleaning fluids that will not damage the ultrasonic cleaning tank. Indirect cleaning is to place the workpiece to be cleaned in a beaker or tray without holes, and the beaker or tray is filled with solution, rather than directly in the cleaning tank. When indirect cleaning is selected, it is confirmed that the water level in the tank is maintained at the standard position.
5. Why need special cleaning fluid for cleaning?
The purpose of using cleaning fluid is to break the connection between the dirt and the workpiece, but using water alone can not achieve the cleaning effect. The main purpose of ultrasonic cavitation is also to assist cleaning fluid to clean. A cleaning solution contains a variety of ingredients to achieve the best cleaning effect. For example, reducing the surface tension of the liquid can increase the cavitation strength, while an ultrasonic cleaning solution may contain a wetting agent or surfactant component.
6. What cleaning fluid should I use?
Ultrasound cleaning liquid is a mixture of many cleaning ingredients, wetting agent and other reactive ingredients. Choosing the right cleaning fluid is very important for cleaning the workpiece effectively and eliminating unwanted reactions. Binengxin can provide you with the best cleaning solution.
7. What kind of cleaning fluid should I not use?
Do not use flammable or low flash point solutions. The energy released by cavitation is converted into heat and kinetic energy and produces high temperature in the solution, which is very dangerous for flammable liquids. Acidic cleaning fluids and bleaching agents should be avoided in general because they can damage stainless steel tanks or cause hazards, but they can be used in indirect cleaning processes, such as using large beakers as indirect cleaning containers.
8. When should I change the cleaning fluid?
When cleaning, it should be replaced if it can be seen that the cleaning fluid is reduced obviously; or when the cleaning fluid is obviously dirty or invalid, the cleaning fluid should also be replaced.
9. Why do I have to keep the cleaning fluid within the allowable height of the level indicator?
Ultrasound cleaning system is a "tuning" system, inappropriate liquid level will change the cleaning environment, thus affecting the frequency of the system, reducing the cleaning efficiency and damaging the equipment. Keeping the proper liquid level can keep the workpiece in the optimum liquid flow and protect the heater and vibration box from being damaged by overheating.
10. What is the length of cleaning time?
The change of cleaning time depends on factors such as dirt, cleaning fluid, temperature and cleanliness requirements. When the ultrasonic cleaning is started, the obvious dirt can be seen to be removed almost at the same time. Adjusting cleaning time is the simplest (and often misused) way to compensate for changes in the process. Although experienced operators can try to ensure the time required for a new cleaning process, they usually need to be validated by choosing cleaning fluid and contaminated workpieces in practical applications.
11. What is the purpose of the heating device?
The huge energy produced by cavitation can generate heat. The main purpose of heating device is to keep the temperature in the cleaning liquid during the cleaning process.
12. What is the best cleaning temperature?
Heating usually provides the speed of cleaning. At the same time, most of the chemical composition in the cleaning solution will achieve the best cleaning effect at a certain temperature. The best way to find the best temperature is to experiment. Usually, the best cleaning temperature will be between 50 and 65 C.
