Application of laser cleaning

Laser has the characteristics of high intensity, high energy density, strong focusing and good directivity. Laser cleaning technology is to use three kinds of actions, such as the vibration of laser pulse, thermal expansion of particles, light decomposition or phase transformation of molecules or their combination to overcome the binding force between the dirt and the substrate surface, so as to make the dirt get rid of the surface and achieve the purpose of cleaning.

Laser cleaning is a kind of "green" cleaning method, which does not need to use any chemical agents and cleaning solution. The waste is basically solid powder, small in size, easy to store, recyclable, and can easily solve the problem of environmental pollution caused by chemical cleaning.
