What are the advantages and disadvantages of a laser cleaner compared to other means of cleaning?
The advantage is: it is in the cleaning capacity of the technical and technological level than almost all traditional industrial cleaning methods;
The disadvantages are: the development time is too short, the development speed is not fast enough. Currently has not been able to cover the full range of industrial cleaning.
Traditional industrial cleaning have various disadvantages:
Sandblasting cleaning will cause damage to the substrate, resulting in a large amount of dust pollution, if the closed box for small power sandblasting pollution is still relatively small, in the open space for high-power sandblasting, will bring a huge dust nuisance;
Wet chemical cleaning will have detergent residue, cleaning efficiency is not high enough, the substrate acidity and alkalinity and surface hydrophilicity, etc. have an impact, and will cause environmental pollution;
Dry ice cleaning cost is high, for example, the domestic ranking in the 20-30 or so tire factory, the use of dry ice cleaning process a year the cost of consumables is close to 80-1.2 million. And it produces secondary waste that is not easy to recycle;
Ultrasonic cleaning can not remove the coating layer, can not clean the soft material, and the submicron particle pollution can not help;
In general, these cleaning processes have a variety of inconveniences, can not meet the manufacturing industry cleaning link to the environmental protection or efficiency requirements.
The advantages of laser cleaning are that it is technically non-contact, more precise and clean, remotely operated, selectively removable, semi-automated or fully automated and unmanned. For example, in the application of selective removal of paint layers, laser cleaning can accurately remove a layer down to the micron level, and after the removal of the surface quality of Sa3 (the highest level), surface hardness, roughness, hydrophilicity, etc. can be preserved to the maximum extent possible as is.
At the same time, the unit cost, energy consumption, efficiency and other aspects are better than other cleaning methods. The environment can be industrial grade zero pollution.
