In ultrasonic cleaning, cleaning agent is essential, it can play the role of dispersion, dissolution and so on. On the basis of the chemical action of cleaning agent, a strong ultrasonic cavitation action can be applied to further promote the chemical action of cleaning agent. In addition, the physical action of ultrasonic cavitation and the chemical action of cleaning agent can cooperate with each other to speed up the shedding of dirt on the workpiece surface and improve the cleaning effect and efficiency. Because all walks of life cleaning workpiece is different, the surface attached dirt properties and degree of contamination, cleaning on the surface corrosion inhibition or rust prevention requirements, cleaning quality and economic cost requirements are different, the selection of ultrasonic cleaning agent should be based on the specific situation analysis, the best choice. At present, there are many choices of cleaning agents suitable for ultrasonic cleaning on the market. From the influence of the properties of cleaning agents on ultrasonic cleaning, the following aspects can be considered in the selection of ultrasonic cleaning agents:

1, workpiece material and dirt properties for different dirt to choose its special cleaning agent, such as oil cleaning agent, rust cleaning agent and so on. Special cleaning agent for specific dirt action, in the adaptability and cleaning efficiency of the more comprehensive consideration.

2, the main mechanism of ultrasonic cleaning agent surface tension, steam pressure, viscosity is cavitation, and the characteristics of the surface tension, steam pressure, viscosity and other cleaning agents are closely related to the strength of ultrasonic cavitation, different cleaning agents of their cavitation thresholds are also different. When the surface tension and viscosity of the cleaning agent are large, it is not conducive to ultrasonic cavitation, and high vapor pressure will also reduce the cavitation strength. Therefore, the surface tension, high steam pressure and viscosity of cleaning agents are not conducive to ultrasonic cleaning.

3. Safety and environmental protection first need to consider the waste liquid treatment problem, preferably normal temperature, low toxicity, safe, efficient new environmental cleaning agent. Secondly, it should be noted that when the ultrasonic cleaning equipment has not done any explosion-proof measures, it is strictly prohibited to use flammable and explosive cleaning agents.

Daily maintenance of ultrasonic cleaning machine

With the application of ultrasonic cleaning machine more and more widely, a variety of novel ultrasonic cleaning equipment after continuous improvement and improvement is replacing the old equipment on the market. In the past 10 years, ultrasonic cleaning machine equipment is developing in two aspects.

One is that various types of multi-cylinder or transmission chain or lifting ultrasonic cleaning production lines have hit the market;

Second, the development of low frequency ultrasonic cleaning machine to high frequency ultrasonic cleaning machine. Blue Whale has summarized the common problems of ultrasonic transducer in the process of years of research and development and production: the ultrasonic oscillator is damp, you can use a megohm meter to check the plug connected with the transducer, check the insulation resistance value can judge the basic situation, the insulation resistance is generally required to be more than 5 megohm. If the insulation resistance value is not reached, the transducer is generally affected by moisture. You can put the transducer as a whole (excluding the spray shell) into the oven to set about 100℃ for drying for 3 hours or use a hair dryer to remove moisture until the resistance value is normal.
