Description

Technical Field

[0001] The utility model relates to the technical field of ceramic processing, in particular to a femtosecond laser processing system for structural color decoration of architectural ceramics. Background Art

[0002] According to the different mechanisms of color generation, colors can be divided into chemical colors and physical colors. Chemical colors, also known as pigment colors, are colors formed by the absorption of light of a specific wavelength by the chemical components on the surface of an object, such as the decorative coloring of glazes, dry particles, inks, etc. containing inorganic and / or organic pigments commonly used in the current architectural ceramics industry. After years of innovation and development, architectural ceramic products decorated with chemical colors are diverse and colorful in terms of decorative effects. However, the resolution of chemical colors is limited by the decorative equipment and the particle size of pigment particles. The highest resolution that can be achieved by inkjet printing technology currently used in the production of architectural ceramic products is 1440dpi (dots per inch); secondly, glazes, dry particles, inks, etc. are easily affected by factors such as chemical composition, decorative technology, and firing system, and the color stability is poor; in addition, due to the types of pigments and processing technology, the color gamut of chemical colors is relatively narrow. Physical colors, also known as structural colors, refer to the colors produced by the orderly microstructure on the surface of an object that causes light to reflect, refract, interfere, and absorb on the interface. Structural colors have the advantages of a wide color gamut and stable color development. For example, the colored textures on the surfaces of CDs, peacocks, butterflies, beetles, and soap bubbles are all structural colors. So far, there has been no report on the application of structural colors in the decoration of architectural ceramic products.

[0003] Femtosecond laser is a kind of -13 Lasers with a period of s and working in the form of ultrashort pulses can obtain instantaneous powers of GW or even TW with very low single pulse energy. They are often used in fields such as ultra-fine processing, but the structures they process are small in size, the processing efficiency is low, and the overall cost is high. So far, there have been no reports on the application of femtosecond lasers in the decoration of architectural ceramic products. Summary of the invention
