In the process of ink production and use, the foam problem will lead to printing defects, reduced efficiency and even equipment corrosion. As a key auxiliary agent, defoamer can quickly eliminate foam and inhibit its regeneration. With the tightening of environmental protection laws and regulations, the market share of water-based ink has increased year by year, but the foam problem caused by water-based ink defoamer due to its high surface tension is also more prominent. Under the increasingly severe trend of environmental protection, how can water-based ink defoamer balance performance and safety?

The water-based ink foam contains a lot of resins and wetting agents, and the foam has strong stability. So when choosing defoamers, we need to comprehensively consider factors such as ink system, pH value, process conditions, and environmental certification. It can be validated through small-scale testing, pilot testing, and multiple experiments. Ensure the performance and safety of water-based ink defoamers.

At the same time, the defoamer industry needs to strengthen industry university research cooperation and promote the intelligent transformation of defoamers. With the development of science and technology, the addition of intelligent defoamers can not only improve defoaming performance, but also ensure the safety of defoamers.
