Color laser marking on bathroom ceramics
Since the laser will be diffusely reflected on the ceramic (near total reflection), so the absorption of laser by the ceramic is very poor. How can the ceramic absorb the laser to mark color text or pattern? The solution is to paint a layer of ceramic coating on the ceramic. The color marking on the ceramic is the result of the interaction between the high-energy laser beam and the ceramic surface. When the temperature reaches 800 °C, the color laser ceramic toner is emitted and penetrate into the ceramic glaze to achieve color marking. At present, two methods: laser coating and laser decal. The laser coating is colored powder,process flow: stir the powder with water and evenly spread it on the ceramic surface, after the coating is dry to start laser marking.Compared with the laser coating,the laser decal is simple and convenient,process flow: soak the laser paper in water and put it attache to the ceramic surface,the laser marking is done after about 5 minutes.
