Comparison between laser cleaning and other cleaning methods

Time: 2020-09-25 15:37 Reading: one hundred and seventy-two second
There are many cleaning methods, such as mechanical, dry ice, chemical, sand blasting, laser cleaning and so on Laser cleaning machine Cleaning is a new green cleaning method in recent years. Specifically, the following describes the comparison between laser cleaning and other cleaning methods.

For the dry ice cleaning method, the cost of dry ice cleaning can be increased and the cost of dry ice cleaning can be reduced in the local dry ice cleaning process. 2. Chemical cleaning mold will corrode the metal material on the surface of the mold. It needs to soak for a period of time to increase the corrosion mold, which is not conducive to the use of cleaning mold for a long time, and will produce industrial wastewater, which is harmful to human health. 3. Sand blasting cleaning mold adopts spraying materials (copper sand, quartz sand, emery, iron sand, sea sand) to the mold surface at high speed, which will cause damage to the mold surface, is not conducive to long-term use of cleaning mold, resulting in air pollution and noise, and may produce inhalable particles to cause damage to the human body.

Mechanical cleaning method has high cleanliness, but it is easy to damage the substrate. Chemical corrosion cleaning method belongs to stress-free cleaning, but the pollution is heavy. Especially when the dirt composition is complex, multiple cleaning agents must be selected for repeated cleaning to meet the requirements of surface cleanliness. Liquid solid jet cleaning has high flexibility, but the relative cost is high. It needs to consume a lot of water and solid impurities, and the later treatment of waste liquid is also complex. Although the cleaning effect of high-frequency ultrasonic cleaning method is good, it can't clean submicron particles with strong adhesion. The size of the cleaning tank limits the size range of the workpiece to be cleaned, and the drying after cleaning is also It's a big problem.

Compared with traditional cleaning methods such as mechanical friction cleaning and chemical corrosion cleaning, laser cleaning has obvious advantages. It has the advantages of high efficiency, fast, low cost, small heat load and mechanical load on substrate, no damage to cleaning, recyclable waste, no environmental pollution, safe and reliable, no harm to the health of operators, and can remove various coatings of different thickness and composition. The cleaning process is easy to realize automatic control and remote control cleaning. Therefore, laser cleaning technology will gradually replace part of the traditional cleaning methods in the future.

Laser cleaning is selective cleaning, that is to say, it has selectivity for the object to be cleaned. This technology can make the substrate surface intact. For different laser pulse width, dirt can not be destroyed by different pulse width and pulse frequency. Wuhan Ruifeng photoelectric laser equipment is cost-effective, with years of laser research and development experience, product technology is mature, product performance is safe and stable. Ruifeng photoelectric laser always adhere to the "quality first, service second, price third" attitude, to provide customers with the best quality products and services.

The above is the comparison between laser cleaning and other cleaning methods. Compared with traditional cleaning, laser cleaning has many advantages. Laser cleaning has the characteristics of environmental protection, which is not found in traditional cleaning. The shortcomings of traditional cleaning methods promote the application of laser technology in the field of surface cleaning.
