As an important ceramic decorative material, ceramic printing ink is widely used in the printing and decoration process of ceramic products. However, in the production and use of ceramic printing ink, foam problems often occur. These foams not only affect the appearance and quality of ceramic printing ink, but also may cause defects in the printing process, such as unclear printing patterns and decreased ink adhesion. Therefore, the application of ceramic printing ink defoamer is particularly important.

The working principle of ceramic printing ink defoamer is mainly to achieve the defoaming effect by reducing the surface tension of the foam liquid film. The defoamer molecules can quickly penetrate into the surface of the foam liquid film, replace the original surfactant molecules, and reduce the local surface tension of the liquid film. Due to the uneven surface tension of the liquid film, the foam breaks. In addition, the defoamer also has the dual functions of breaking and suppressing foam. The breaking function can quickly destroy the formed foam, while the suppressing function can prevent new foam from being generated again.

The amount of defoamer added needs to be strictly controlled. Too little addition may not achieve the ideal defoaming effect, while too much addition may affect the performance of the ceramic printing ink and even cause defects in the printed pattern. Generally speaking, the amount of defoamer added should be based on the volume of ceramic printing ink and the degree of foam generation, and the optimal ratio should be determined through field tests.

Ceramic printing ink defoamers play an important role in the field of ceramic printing ink. By rationally selecting and using defoamers, it is possible to effectively control the foam problem in the production and use of ceramic printing ink, improve the quality and printing performance of ceramic printing ink, and protect the environment. In the future, with the continuous improvement of environmental protection requirements and the continuous advancement of technology, ceramic printing ink defoamers will develop in the direction of environmental protection, high performance, and intelligence, providing strong support for the sustainable development of the ceramic printing ink industry.
