In recent years, with the worldwide awareness of environmental protection, the development of the cleaning industry is facing a huge challenge. In line with the needs of the times, there are a variety of cleaning technology to protect the environment, laser cleaning technology is one of them.
So what is laser cleaning technology?
A laser cleaner is a device used to remove various types and types of deviations from metal surfaces. It is a new technology based on the interaction between laser and material.
Compared with mechanical friction cleaning, chemical corrosion cleaning, high impact liquid-solid cleaning and high frequency ultrasonic cleaning and other traditional cleaning methods, laser cleaning has obvious advantages. Efficient, fast, inexpensive, low thermal and mechanical stress on the substrate, non-destructive cleaning; waste can be recycled, no environmental pollution; safe and reliable, does not endanger the health of the operator; it can remove different coatings of different thicknesses, the composition of the cleaning process can be easily automated control, remote cleaning. It can be seen that laser cleaning technology will gradually replace some traditional cleaning methods in the future.
Features of laser marking machine for rust removal
Laser has the characteristics of high controllability, monochromaticity, high coherence and high brightness. By focusing, the energy can be concentrated in a small space-time domain. In the laser cleaning process, the following characteristics of the main use of laser cleaning machine:
1. Laser cleaning machine can achieve a high concentration of energy in space and time. Focused laser beam in the vicinity of the source of fire to produce thousands or even tens of thousands of degrees of high temperature, which can lead to the vaporization, instantaneous vaporization or degradation of contaminants.
2. Laser cleaning beam divergence angle is small, good directionality, focusing system can focus the laser beam on different diameters of the spot. With the same laser energy to check the different diameter of the laser beam spot.
3. The laser can adjust the laser energy density to make the dirt expand by heat. If the expansion force of the contaminant is greater than the adsorption force of the contaminant on the substrate, the contaminant will be separated from the surface of the object.
How does a laser cleaner work?
The laser cleaning process works by sending multiple laser pulses to the surface. As the laser strikes the substrate or metal surface, the contaminants escape from the surface or evaporate into a gas, carrying them away from the metal surface or the absence of a metal surface.
What can laser cleaners remove?
Laser cleaners can basically remove rust or oxidation from metal surfaces and can also clean other non-metallic materials.
In addition to metal rust, we can actually remove paint, oxidation, graffiti and other substances that may contaminate the substrate with a laser rust remover.
What industries can laser cleaners be used in?
The most common use of laser cleaners is to remove rust and oxidation from metal surfaces. Since there are many companies and industries that use metal, you will be able to use a laser rust remover in many different industries. Such as:
1. Quick removal of metal or glass surface coatings.
2. Fast removal of rust, various oxides.
3. Removal of grease, resin, glue, dust, stains, production residues.
4. Roughening of metal surface, cleaning of metal surface in confined space.
5. Paint removal, rust removal, oil removal, post-weld oxidation, pre-weld residue treatment or glue application.
6. Cleaning of tire molds, electronic molds, food molds and other molds.
7.Eliminate oil stain after manufacturing and processing of precision parts.
8.Fast cleaning and repair of nuclear power battery repair.
9. Oxidation, paint removal, rust removal, shipbuilding or repair of space shuttle and weapons.
10. Cultural monuments cleaning, rock cleaning, building exterior surface cleaning.
Laser cleaning technology has developed rapidly in the past two years. In the laser cleaning machine process parameters and cleaning mechanism, looking for cleaning objects or looking for applications has made great progress, the market prospects are very broad. With the reduction of the cost of lasers and their hardware, the application of the technology is also expanding, becoming the new favorite of the industry and the market.
