Лазерная чистка, in terms of its mechanism for mold cleaning, uses a clean substrate (also called a precursor) and a surface attachment (soil) to have a very different absorption coefficient for a certain wavelength of laser energy. Most of the laser energy radiated to the surface is absorbed by the surface deposits, which is heated or vaporized and evaporated, or instantaneously expanded, and is driven by the vapor stream formed on the surface to separate from the surface of the object for cleaning purposes. Specifically used for tire mold cleaning, the mold absorbs laser light of a specific wavelength, the energy is very small, and will not cause damage. The dirt on the surface of the mold (sulfide, inorganic oxide, silicone oil, carbon black, и т. д.) absorbs a large amount of energy and is instantly expanded. Vaporization evaporation, away from the mold surface, to achieve the effect of cleaning. The main methods of лазерная чистка are:

1) laser dry cleaning method, то есть, direct radiation decontamination using pulsed laser;

2) лазер + liquid film method, то есть, first deposit a liquid film on the surface of the substrate, and then decontaminate with laser radiation;

3) Лазер + метод инертного газа, то есть, while the laser radiation is being used, the surface of the substrate is purged with an inert gas.

Когда грязь счищается с поверхности, он будет немедленно сдут с поверхности газом, чтобы избежать повторного загрязнения и окисления поверхности.;

4) Use a laser to loosen the dirt and then clean it with a non-corrosive chemical method. Currently, the first three methods are commonly used. The fourth method is only found in the cleaning of stone artifacts. The advantages of laser cleaning are high efficiency, quickness, бюджетный, low heat load and mechanical load on the mold, and will not damage the workpiece to be cleaned; waste can be recycled without environmental pollution; safe and reliable, without damaging the health of the operator; It can remove dirt of various thicknesses and different compositions; the cleaning process is easy to achieve automatic control, remote cleaning and so on. The disadvantages of laser cleaning are high equipment investment, high technical level for maintenance and use, technology monopolized by foreign countries, and subject to technical services and parts supply.
