The Magical Laser Cleaning Technology
2018-03-27 30 Back to list
The laser cleaning technology uses the high energy density of the laser and the impact and vibration of the laser pulse on the surface of the object to be cleaned. By using the difference between the laser absorption coefficient of the substrate and the attached matter, the attached matter or coating on the surface instantaneously evaporates or peels off, thereby achieving a clean process. As a new type of environmentally friendly cleaning technology, laser cleaning has been applied more and more widely to various fields. In addition to the field of cultural heritage protection, laser cleaning technology has also been used in 3C electronics, automotive parts and rail transportation processing.
Cleaning has always been a very important part of industrial production and scientific research. Traditional cleaning methods include mechanical cleaning, chemical cleaning, and ultrasonic cleaning, but their application is greatly limited under the requirements of environmental protection and high precision.
On the one hand, traditional cleaning techniques mainly remove contaminants on the surface by means of dissolution, chemical reactions or mechanical forces. Therefore, there are certain difficulties for parts that require high cleanliness (such as cleaning submicron-sized particles); On the one hand, traditional cleaning techniques can easily lead to secondary pollution and increase the complexity of cleaning.
Laser cleaning is characterized by non-abrasive, non-contact, non-thermal effects and objects suitable for various materials. It is considered to be the most reliable and most effective solution. At the same time, laser cleaning can solve problems that can not be solved by using traditional cleaning methods.
The laser cleaning equipment introduced by HGLaser has the advantages of easy handling, easy automation and integration, no chemical reagents, conformable surface cleaning, high cleanliness, high precision, high efficiency, environmental protection, safety and reliability, almost no damage to the surface of the substrate, and can solve many problems that traditional cleaning can't solve.
