Novel carbon dioxide treatment method

Abstract

The invention discloses a novel carbon dioxide treatment method which comprises the following specific steps: (I) performing pretreatment, soaking a fixture, fixing a product on the fixture, and performing electrostatic dust removal for the fixture and the product. In the technology, a base material is sequentially subjected to primer spraying, electroplating, spraying, carbon dioxide laser carving and curing, then a matte high-brightness edge with metal texture is formed more easily on the surface of the product, and the delicacy of the bright side and matte side of the surface of the product can be directly felt on the using hand feeling; and meanwhile, after carbon dioxide laser carving, surface paint is not scorched, and thus the roughness of molecules can be better adjusted while the accuracy of a carving position is improved.

Description

technical field [0001] The invention relates to the field of painting technology, in particular to a novel carbon dioxide treatment method. Background technique [0002] Matte is also called matte. Matte is relative to flat light, that is, non-bright surface. It can avoid light pollution and is more convenient to maintain. The matte surface is a bit hairy, like the surface of frosted glass. The reflected light is "diffuse reflection", without glare and glare, giving people a sense of stability and elegance. The bright light has a smooth surface, and the mirror reflection of the reflected light has glare. Gives a bright and gorgeous feel. [0003] Carbon dioxide treatment is different from other ordinary laser engraving. Carbon dioxide treatment is a gas laser with a wavelength of 10.64um in the far-infrared band. 2 The gas is filled into the discharge tube as the medium for laser generation. When a high voltage is applied to the electrode, a glow discharge is generated...

Problems solved by technology

[0004] Existing laser engraving machines usually use ordinary laser for processing (thermal processing). This type of laser has a high energy density laser beam (it is a concentrated energy flow) irradiated on the surface of the processed material, and the surface of the material absorbs the laser. Energy, a thermal excitation process is generated in the irradiated area, so that the temperature of the material surface (or coating) rises, resulting in metamorphosis, melting, ablation, evaporation, etc.), which will cause wear and tear on the paint surface and cannot be used;
