A kind of manufacturing process of ceramic material surface marking

Abstract

The invention discloses a technology for manufacturing a marker on the surface of a ceramic material. In the ceramic material, the content of cordierite is more than 90 percent; the surface of the ceramic material is dry and is burned by a laser beam; the wavelength of the laser beam is 1.06 microns; the output power of the laser beam is 20-50w; during burning, the laser beam is focused; a distance from a burning point to a focusing lens is 75 to 120 percent of the focal distance; and the scanning speed of the laser beam on the ceramic surface is 50-250mm / s. In the laser marking technology, based on the properties of the cordierite, specific laser parameters are selected, the marking speed is high, the marker is firm and reliable, an object to be marked is not damaged and the working environment is good.

Description

technical field [0001] The invention relates to a marking process, in particular to a marking process on the surface of ceramic materials. Background technique [0002] The application range of ceramic materials is becoming wider and wider, not only as daily necessities, but also in industrial fields. [0003] Cordierite is a silicate mineral that can be colorless, but usually has a light blue or light purple, vitreous luster. Cordierite also has a characteristic that they emit light of different colors in different directions, which is called pleochroism. Iolite is considered a gemstone, but it has no other industrial uses. Cordierite occurs in schist, gneiss and altered igneous rocks. People therefore also call cordierite dichromatic stone. Magnesium cordierite can be synthesized artificially for refractory materials. [0004] Because of cordierite's excellent high temperature resistance and other stability properties, cordierite is used as a ceramic material carrier ...

AI Technical Summary

Problems solved by technology

[0006] 1. Its adhesion is not enough, and it is easy to become blurred or even fall off under the action of external friction;

[0007] 2. Printing is difficult, especially when encountering curved surfaces, printing is extremely difficult;

[0008] 3. The accuracy of the printed pattern or text is not high, and when the printed pattern or text is small, it is not clear;

[0009] 4. The printed dye is unstable, and it is easy to fade under high temperature or corrosive environment, so the marked object cannot be dried at high temperature or subjected to intense chemical treatment
