Ultrasonic cleaner technology has been around for more than 30 years and was first used in Japan 25 years ago, but a misconception has plagued the technology, causing people to doubt the effectiveness of ultrasonic cleaners. The traditional theory of ultrasonic cleaner that the bubble plays a role in cleaning. Shibano Yoshihide after repeated tests found that, in fact, the bubble is only caused by the ultrasonic wave of strong coarse dense wave caused by a simple gas burst, it will inhibit or even eliminate the ultrasonic cleaner cleaning power, the real role of cleaning is the vacuum cavities. This discovery was a revolutionary breakthrough in the field of ultrasonic cleaners, and in 1987, Yoshihide Shibano published the basic theory of ultrasonic cleaners, and in order to differentiate it from conventional theories, he called his research results the "Shibano Theory", and the ultrasonic cleaner technology based on it was defined as the New Ultrasonic Cleaner Technology. He developed the ultrasonic cleaner equipment based on this theory, the cleaning effect is much better than similar products, can successfully control the occurrence of cavitation phenomenon location, occurrence of density, occurrence of efficiency and impact. Other manufacturers in the industry to spend 25 minutes still can not be well cleaned to remove welding burrs, with Pleiades cleaning equipment in 6 seconds can be removed; other manufacturers in the industry to spend 2 hours of equipment is still unable to remove the dense portion of the flux, Pleiades can be removed in 2 minutes and ensure that there is no damage to processed objects.
The birth of "Pleiades" Talking about the history of ultrasonic cleaning machine research, Shibano Yoshihide particularly excited. 1970, Shibano Yoshihide from the Japanese National Fukushima Industrial College, Electrical Engineering, graduated from the National Fukushima Institute of Technology, working in the Snake Eyes Sewing Machine Industrial Technology Research Institute. 1975, he entered an industrial cleaning company. In 1975, he joined an industrial cleaning company. At that time, ultrasonic cleaners were just beginning to be available, but toxic and hazardous chemical solvents such as trichloroethylene and freon were used in large quantities as cleaning media, causing considerable pollution of the environment. At that time, Japanese industry was in a period of rapid development, and a large amount of industrial wastewater was discharged into the rivers, and many people became sick from drinking contaminated water, and some disabled people, in particular, died prematurely because they were forced to work in toxic and harmful jobs for a living. When Yoshihide Shibano witnessed all this, his strong sense of social responsibility made him determined to use environmental protection technology for the benefit of mankind, and he said, "The world raised me, and I have an obligation to contribute to the world!" From then on, he embarked on the road to research environmental ultrasonic cleaner.
A chance factor prompted him to discover the wonders of ultrasonic cleaner. At that time, due to the lack of funds, everything can only be simple, test equipment is not to talk about. Because most of the ultrasonic cleaning machine tank made of stainless steel, can not be observed from the side of the ultrasonic generated in the media, and Shibano Yoshihide because of the lack of money, bought a transparent plastic fishbowl instead, so that it is easy to observe the changes in the cleaning tank. He found that the ultrasonic generator placed at the bottom of the fish tank produces a lot of bubbles continue to rise, a large bubble into two small bubbles, and finally exploded. The principle of the traditional ultrasonic cleaner is through the ultrasonic wave propagation in the liquid medium to produce bubbles, and then through the explosion of bubbles generated by the force to play the effect of cleaning the surface of the object. However, because of the presence of air in the bubbles, the force generated by the explosion is limited, so the cleaning effect is not satisfactory. Yoshihide Shibano finally developed a new ultrasonic cleaner device through repeated trials and continuous improvement, making the air bubbles become air pockets in a vacuum, thus correcting a long-standing misunderstanding of ultrasonic cleaner technology. He also tried to use water to replace the previous ultrasonic cleaner commonly used Freon and other toxic and harmful media, to the goal of environmental protection a step further, in 1993 this invention won the "U.S. Environmental Protection Agency (EPA) to protect the ozone layer Environmental Protection Award. He invented the cleaning force digital meter, can be measured at any time ultrasonic sound pressure and cavitation impact, so that the cleaning device will be adjusted to the best state.
Ultrasonic cleaning machine technology has such a long history, proving that its technology is reliable, ultrasonic cleaning machine technology will have good development.
