Beneficial effect: body paint laser cleaning system provided by the invention, high power laser light directly reacts with enamelled coating, and when guaranteeing the effective paint removal of clean surface by blow and bleed simultaneously, the phenomenon and the cleaning efficiency that do not produce damage substrate are high.
With traditional vehicle body paint removal method Comparatively speaking, the method that this patent proposes has following many technology and economic superiority:
(1) strong, the environmental protection of cleaning force: this cleaning method continuous laser power used is generally larger, because the energy density of laser is high and hot input is large, can be directly by the direct combustion decomposition of the enamelled coating of metal surface.And owing to there being the air blowing protective effect of inert gas simultaneously, cleaning process be can't see combustion phenomena, the product after enamelled coating decomposes is directly sucked by getter device, so environmentally safe.
(2) parameter range of choice is large, applicability is wide: in cleaning parameter, laser power size range of choice is between 0w～500w, between can be chosen in-100mm of defocusing amount～+ 100mm, cleaning speed is the highest can reach 7000mm/s, and laser rays spacing is also adjustable.Therefore, also can pass through the common plain color paint of matching purge of different technical parameters, also can clean the thicker strong metallic paint of making a concerted effort of knot.
3 cleaning qualities are high, effect stability: by the accurate setting of high power laser light effect, good inert gas shielding condition and various technological parameters, guaranteed to affect the principal element of cleaning quality.In addition the reasonable integrated and stability of equipment, thus the stability of cleaning quality and cleaning performance guaranteed.
(4) cleaning efficiency is high.This cleaning method cleaning efficiency can reach 100mm
2/ more than, when the paint removal of large area vehicle body or batch paint removal, efficiency obviously, due to traditional paint removal method, is enough to get caught up in the beat requirement of the process procedures such as follow-up touch-up paint.
