Ultrasonic cleaning machine solves the problem of industrial cleaning

ultrasonic cleanerSolving the problem of industrial cleaning

There are many manufacturers of ultrasonic cleaning machines with a wide range of models, but their main function is to complete the cleaning of various objects, and the cleaning effect is widely recognized by users. In many industrial manufacturers, they face such problems. In the process of degreasing, descaling, washing, surface treatment, phosphating and other processes penetrate the weld liquid is difficult to discharge, can not be completely removed from the wash. Under high temperature and high humidity conditions, inclusions tend to turn yellow and the workpiece. Rust. If these residual liquids can not be completely dried in the drying process, and then the powder coating is dried at high temperatures, the residual liquid will seep out of the weld due to thermal expansion, affecting the combination of the coating and the metal surface, resulting in a reduction in the adhesion of the coating. Even transcendent.

For this problem, general factories use high-pressure spraying and multiple washing, or change the drying process to increase the drying temperature to solve the residual liquid left in the cracks. These methods not only cause waste of water and energy, but also high temperature drying will damage the phosphating film and reduce its corrosion resistance, so the effect is not ideal. Ultrasonic flushing using ultrasonic "non-porous" and "cavitation" characteristics, can quickly and thoroughly remove the residual liquid and debris in the welded joints to meet the quality requirements of subsequent processing.

Studies have shown thatultrasonic descalingand rinsing depends on cavitation, which is generated with respect to the ultrasonic intensity. Cavitation is usually produced by water-soluble media with an ultrasonic power of 0.3 / cm2 per unit area. Within a certain range, the higher the ultrasonic intensity, the more pronounced the cavitation effect. Typically, a cleaning power of 1 to 1.2 w / cm2 is preferred.

Ultrasonic vibration frequency has a great influence on the cleaning effect. Under the same power conditions, it is easy to exacerbate cavitation at low frequencies, that is, the optimal cavitation effect is 16~25khz. For surface treatment, the low frequency of 16~20khz is suitable for large and medium-sized mechanical parts that are heavily oiled and rusted. For certain parts with high surface cleanliness and blind and wire holes, 26khz is appropriate.

ultrasonic cleaningTemperature is an important factor affecting cleaning speed. Increasing the cleaning temperature appropriately increases the cavitation capacity and shortens the cleaning time. However, when the temperature exceeds a certain temperature, the cavitation decreases due to the increase in vapor pressure, so a certain temperature must be maintained. Tests have shown that water-soluble media are usually most effective at 50°C ± 5.
