In industrial cleaning, traditional cleaning has a variety of cleaning methods, mostly using chemical agents and mechanical methods for cleaning.
There are mainly mechanical cleaning method, chemical cleaning method and ultrasonic cleaning method. At present, these three cleaning methods dominate the cleaning market in China, but their application is greatly restricte under the requirements of environmental protection and high precision.
Can not meet the high cleanliness cleaning requirements, easy to damage the surface area of the workpiece being cleaned.
Chemical cleaning method
It is easy to cause environmental pollution, and the degree of cleanliness obtained is also very limite. Especially when the dirt composition is complex, multiple cleaning agents must use to repeatedly clean to meet the requirements of surface cleanliness.
Ultrasonic cleaning method
Although the cleaning effect is good, the cleaning of sub-micron dirt particles is powerless. The size of the cleaning tank limits the scope and complexity of the processed parts, and drying the workpiece after cleaning is also a major problem.
Due to the increasing awareness of environmental protection and safety. The requirements of national environmental protection regulations are becoming more and more strict. And the types of chemical drugs that can use in industrial production cleaning will become fewer and fewer. In this case, the laser cleaning technology is gradually replacing the traditional cleaning technology due to its unmatched advantages.
