With the continuous development of the printing industry, the quality and performance requirements of ink are increasingly increasing. Among them, ink defoamers play an important role as key additives in improving ink quality and production efficiency.

During the preparation and printing of ink, due to mixing, extrusion and other operations, it is easy to introduce air to produce foam. Defoamers can effectively inhibit the formation of these foam and prevent them from adversely affecting ink performance. Foam will cause pores and unevenness in the ink coating, affecting the printing quality. The use of defoamers can significantly improve the coating performance of ink, making the coating smoother and more uniform, reducing the number of pores, and thus improving the quality of the coating. Defoamers help stabilize the emulsion state of ink, prevent oil-water separation, and extend the stability and shelf life of ink. This is of great significance for long-term preservation and transportation of ink. In addition, the accumulation of foam in printing equipment may lead to clogging of nozzles, pipes and filters, reducing production efficiency. The use of defoamer can reduce the accumulation of foam, reduce the risk of equipment blockage, and thus improve production efficiency.

Ink defoamers are widely used in various printing inks, including water-based inks, oil-based inks, etc. In water-based inks, defoamers can optimize the coating performance and printing quality of the ink; In oily ink, defoamer can effectively control foam problem and improve the clarity and accuracy of printed matter.

In addition, with the increasing awareness of environmental protection, the application of environmentally friendly water-based inks is becoming increasingly widespread. As an important additive for water-based inks, defoamers have increasingly attracted attention for their environmental performance. At present, there are various environmentally friendly defoamers on the market, such as polyether block defoamers, organosilicon defoamers, etc. They not only have good defoaming performance, but also meet environmental requirements. With the continuous development of the printing industry, the performance and application scope of defoamers will also continue to expand. In the future, we can look forward to the emergence of more efficient and environmentally friendly ink defoamers, making greater contributions to the development of the printing industry.
