With the increasing global awareness of environmental protection and the deepening of sustainable development concepts, the green development of water-based ink defoamers has become an important trend in the industry. Water based ink is widely used in the printing industry due to its environmental friendliness, low VOC emissions, and low odor. However, the issue of bubbles in ink has always been one of the key factors affecting printing quality, making the use of defoamers indispensable.

Water based ink defoamers are gradually transitioning from traditional materials such as mineral oil and metal soap to more environmentally friendly bio based and biodegradable materials. These new materials not only have excellent defoaming properties, but also reduce environmental pollution. With the continuous advancement of technology, the defoaming efficiency and anti foaming ability of defoamers have been significantly improved. This means that while achieving the same defoaming effect, the amount of defoamer used can be significantly reduced, thereby reducing its impact on the environment. Future water-based ink defoamers will not only have defoaming functions, but may also have multiple functions such as antibacterial, rust proof, and thickening. This trend towards multifunctionality will help improve the overall performance of ink and the quality of printed materials.

The green development of water-based ink defoamers is also reflected in their recycling. By recycling and disposing of waste ink and defoamers, resource waste and environmental pollution can be reduced.

Although significant progress has been made in the development of environmentally friendly defoamers, there are still some technical bottlenecks. For example, one of the main challenges currently faced is how to further improve defoaming efficiency and foam suppression ability while maintaining good compatibility and stability. The production cost of environmentally friendly defoamers is usually high, which limits their widespread application in the market. How to reduce costs while ensuring defoaming performance is a problem that the industry needs to solve.

With the increasingly strict environmental regulations, the production and use of water-based ink defoamers need to comply with stricter environmental standards and requirements. This will put forward higher requirements for the production technology and product quality of enterprises.

Although green defoamers have many advantages, market promotion still faces certain difficulties. Consumers' awareness and acceptance of green products need to be further improved, while enterprises also need to strengthen market promotion and brand building.

The green development trend of water-based ink defoamers is irreversible. With the continuous advancement of technology and the increasing awareness of environmental protection, more environmentally friendly, efficient, and multifunctional defoamers will emerge in the future. At the same time, the government, enterprises, and consumers will also work together to promote the green development of the water-based ink defoamer industry.
