Challenges and breakthrough directions facing the development of the defoamer industry at the current stage

Defoamers, as key additives widely used in chemical, food, pharmaceutical, sewage treatment and other fields, are facing multiple challenges in their technological development, such as upgraded environmental requirements and complex application scenarios.

With the increasing global attention to environmental issues, laws and regulations in various countries have become increasingly strict on the volatile organic compounds and persistent pollutants in traditional defoamers such as organosilicon and mineral oils. Traditional defoamers (such as silicone oil) rely on high molecular weight hydrophobic particles to achieve rapid defoaming, but these materials are often difficult to degrade; However, the stability and instantaneous defoaming efficiency of bio based defoamers (such as glycolipids and proteins) are insufficient, making it difficult to meet the needs of high-speed papermaking or oil field extraction scenarios.   

The innovation of green materials and the precise design of structures have brought new breakthroughs to the defoamer industry. The degradation rate of bio based defoamers in wastewater treatment can reach over 90%; Nanocellulose defoamer utilizes wood fiber nanomaterialization technology, which combines degradability and high shear stability. Intelligent responsive defoamers can spontaneously migrate to the liquid surface to break bubbles at high temperatures and remain inert at low temperatures to reduce waste and thus lower production costs.  

At present, the defoamer industry is in a critical period of "environmental breakthrough" and "technological iteration". Only through the collaborative innovation of materials science, process engineering, and digital technology can the current dilemma be solved.
