The technical journey of decrypting ink defoamers from laboratory to production line

In the ink manufacturing process, the production of foam often affects the printing quality, resulting in surface defects, uneven color and even equipment blockage. To solve this problem, defoamers have emerged. However, an efficient ink defoamer requires complex technological breakthroughs and process optimization from laboratory research and development to final production line deployment.

The core function of defoamer is to destroy the stability of foam. In the laboratory stage, researchers first need to understand the formation mechanism of foam. The cause of foam is that the surfactant, resin and other components in the ink are easy to wrap up the air in the process of stirring or high-speed printing, forming a stable foam. The defoaming principle of defoamer is to eliminate foam by reducing surface tension, destroying liquid film or promoting bubble combination.   

Laboratories typically test various defoaming ingredients, including organosilicon, mineral oils, and polymers. After different experimental results, multiple repeated experiments were conducted to evaluate the defoaming efficiency, compatibility, and durability of different formulations, in order to avoid affecting printing gloss or leveling. Ensure effective operation in different printing environments and help ink companies solve these technical challenges.

The technological journey of ink defoamers is a perfect combination of chemistry, engineering, and market demand. From molecular design in the laboratory to large-scale manufacturing on the production line, every step embodies the wisdom of researchers and engineers. In the future, with the development of green printing and intelligent manufacturing, defoamer technology will continue to break through, providing more efficient and environmentally friendly solutions for the printing industry.
