As an indispensable and important additive in the paper industry, papermaking defoamers have witnessed a leap from chemical synthesis to biotechnology in their development process. With the advancement of technology and the improvement of environmental awareness, the innovative path of papermaking defoamers is developing towards a greener, more efficient, and sustainable direction.

Although traditional chemically synthesized defoamers meet the needs of the paper industry to some extent, their production process may produce harmful substances that are difficult to degrade after use, posing a potential threat to the environment. In addition, chemically synthesized defoamers may fail under specific conditions such as high temperatures and strong acid-base environments, limiting their application in certain high-end papermaking processes.

To address the limitations of chemical synthesis of defoamers, biotechnology has provided new ideas for the innovation of papermaking defoamers. By using biotechnology methods such as microbial fermentation and plant extraction, biobased defoamers with excellent defoaming properties and good environmental performance can be prepared. These bio based defoamers not only have minimal environmental impact during production, but are also easy to degrade after use and will not cause long-term harm to the ecosystem.

In recent years, many domestic and foreign enterprises have successfully developed bio based paper defoamers and achieved good results in actual production. For example, some companies use the metabolic products of specific microorganisms as the main components of defoamers, which not only achieve efficient defoaming effects, but also significantly improve the quality and production efficiency of paper. In addition, with the continuous development of cutting-edge technologies such as genetic engineering and synthetic biology, the innovation of paper defoamers in the future will be more diversified and intelligent.

Although significant progress has been made in the application of biotechnology in the field of papermaking defoamers, there are still some challenges that need to be addressed. For example, the production cost of bio based defoamers is relatively high, and their performance under certain specific conditions (such as extreme temperature and pressure environments) still needs further optimization. In addition, how to ensure that bio based defoamers do not have negative impacts on papermaking equipment and the environment during long-term use is also a concern that needs to be addressed in the future.

In summary, the innovative path of papermaking defoamers is developing towards a greener, more efficient, and sustainable direction. Through continuous technological innovation and research and development, we believe that in the future, more environmentally friendly and efficient bio based paper defoamers will emerge, contributing to the green development of the paper industry.
