With the continuous development of the printing industry and the increasing demand, the quality and performance requirements of printing inks are getting higher and higher. However, foam generation has always been a headache in the production of printing inks. Foam can affect the uniformity and flow of the ink, as well as the quality of the print, and can even lead to equipment clogging and reduced efficiency. To solve this problem,BYK-1752 defoamerIt has become an important tool.
BYK-1752 defoamerIt is an oil-based non-silicone defoamer that does not contain aromatic hydrocarbon components, and the application of this defoamer can play a role in different aspects of printing inks, such as mixing, grinding and storage processes
1.In the ink mixing process, adding an appropriate amount of defoamer can prevent the formation of bubbles, which can effectively reduce the surface tension between pigments and resins and other components, and prevent the dissolution and aggregation of gases in the ink, thereby reducing the generation of bubbles. In addition, the defoamer can also provide a certain wettability, improve the dispersion of pigments and resins, and make the ink more uniform and stable.
2.During the grinding process, the use of defoamers avoids excessive foam due to the friction between the pigment and the resin. Choosing the right defoamer for the grinding process is critical, as different machinery and ink compositions may require specific defoamer products. Correct use can make the grinding process more stable and efficient, and avoid the influence of foam on ink quality.
3.During ink storage, adding a defoamer can prevent foaming problems caused by prolonged storage. Defoamers can destroy the membrane structure on the surface of the ink during storage, preventing the formation and accumulation of air bubbles. This is important to maintain the stability of ink quality and extend the shelf life of the ink, reducing the generation of rejects.
