What are the main components of the ceramic ink used in digitally printed glass?

The ceramic ink used for digitally printed glass is mainly composed of the following key components:

Inorganic mineral pigments: This is the main component responsible for color development in the ink. Inorganic mineral pigments have extremely strong stability and weather resistance, can maintain bright colors and are not easy to fade at high temperatures. They are usually composed of non-ferrous metal oxides or some metal insoluble metal salts, such as chromium oxide, cobalt blue, cadmium sulfide, etc., which are used to produce various colors.

Submicron glass powder: As a filler and carrier in the ink, submicron glass powder can help the pigment adhere firmly to the glass surface during the printing process. At the same time, it can also fuse with the glass surface at high temperatures to form a solid glaze layer.

Binder: The binder is one of the main components of the ink. It plays a role in dispersing the pigment and giving the ink proper viscosity, fluidity and transfer performance. After printing, the binder fixes the pigment to the glass surface through film formation. The binder is usually composed of synthetic resins and organic solvents. These substances can complete the evaporation, sublimation and combustion processes at low temperatures to avoid residues when the glass powder melts.

Solvent: Solvent plays a role in lowering the melting point of the glaze in the ink, so that the glaze can penetrate into the glass when it is softened and adhere firmly. Common solvents include lead oxide, boron oxide, etc., which have good water resistance and appropriate melting point, and can match the temperature and thermal expansion coefficient of the printed glass.

Additives: In order to improve the performance of the ink itself or meet specific printing requirements, some additives may be added to the ink, such as desiccants, anti-desiccant, detackifiers, etc. These additives can play an important role in the process of ink manufacturing and printing, ensuring the quality and stability of printed products.

The ceramic ink used for digital printing glass is a complex system, which is composed of multiple components such as inorganic mineral pigments, submicron glass powder, connecting materials, solvents and additives. These components work together to ensure the stability of the ink during the printing process and the high quality of the printed products.
