With the increasing global awareness of environmental protection and the expansion of industrial production scale, water-based ink, as a more environmentally friendly ink type, has seen continuous growth in market demand in recent years. However, in the production and use of water-soluble ink, the production of foam often becomes a problem that cannot be ignored. Foam not only affects the fluidity of ink and printing quality, but also may lead to the failure of printing equipment and the reduction of production efficiency. Therefore, water-based ink defoamers are particularly important as a powerful assistant in solving ink foaming problems.

The main function of water-based ink defoamers is to reduce the surface tension of the liquid, making it easier for bubbles to burst and disappear. Defoamers are usually composed of various surfactants and additives, which can quickly penetrate the surface of bubbles, form a thin film, and inhibit the generation and stability of bubbles. By adding defoamers, the number of bubbles in the ink can be effectively reduced, improving the fluidity and stability of the ink.

In today's pursuit of both industrial efficiency and environmental protection, the green and sustainable development of water-based ink defoamers has become an important issue. Although traditional oil-based defoamers have good defoaming effects, the volatile organic compounds (VOCs) they contain cause certain pollution to the environment. Therefore, the promotion of environmental policies has increased the demand for water-based defoamers, and replacing traditional oil-based defoamers has become a trend.

In the future, water-based ink defoamers will pay more attention to green, non-toxic and harmless ingredients, comply with environmental standards, and ensure the safety of the production process. Meanwhile, with the continuous advancement of biotechnology, bio based defoamers will become a new development direction. Biobased defoamers use renewable resources as raw materials, which not only have excellent defoaming performance, but also can rapidly degrade in natural environments, reducing their impact on the environment.

In addition, the research and development of water-based ink defoamers will also move towards more efficient and multifunctional directions. For example, defoamers that possess both antibacterial and high-temperature resistance properties will better meet the needs of modern industry. At the same time, the application fields of defoamers will be further expanded, not only limited to the printing industry, but also involving new energy, electronic materials and other fields.

In summary, the green and sustainable development of defoamers in the water-based ink market is an important trend. In the future, with the improvement of environmental awareness and continuous technological progress, water-based ink defoamers will become more environmentally friendly, efficient, and multifunctional, providing strong guarantees for the healthy development of the water-based ink industry.
