Urban graffiti removal by laser cleaning machine for wall/building/bridge/chair/tree 200W Laser Power
There is oxidation and corrosion when metals meet oxygen and water vapor in air. It will greatly damage the metal workpiece and the rust will spread from outside to inside and become worse and worse as time goes on, until the whole workpiece is totally corrupted. So rust removal is extremely important. Laser rust removal uses not chemical agents or mechanical polishing, so it is faster and safer. It has advantages of higher efficiency, high automation and no subsequent processing work, lower labor intensity and lower cost.
QA-LC200 equipped with a 200W Mopa fiber laser source, the pulse width can be adjusted from 10-400ns, so it can make precision cleaning, like plastic injection mold ,autombile plastic mould and mirror stainless steel.
1. The impact of a short period of time will not cause metal surface heating, no damage to the substrate.
2. Pollution-free: It is easy to solve the environmental pollution problems caused by chemical cleaning without using any chemical agents and cleaning liquid.
3. Expansibility: changeable focus lens, changing focus depth, wider range of laser cleaning beam.
4. No damage to the base material;
5. Fast and concentrated pulses (1/10000 second) with enormous power (well dozens of of Mio. W) impact and gasification of residues on the surface;
6. Laser pulses are very suitable for the removal of organic matter, such as residues in the tire mold fouling;

Removal for rust, oil stain, grease, dirt, resin, mold release, oil paint, coating, weld residue, oxide, production residue etc.
High energy pulsed laser focusing on the surface of object to simulate plasma, continuous irradiation of high-energy plasma instantaneous formation and expansion, resulting in a series of tiny explosions, formating plasma blasting, finally achieve the relativel smooth corrosive layer of boject surface to physical blasting burst, and move through the high speed laser spot to form a plume that will clean the debris to complete the cleaning. Mainly used in metal rust.
