As an important component of traditional manufacturing, the paper industry's technological progress and product innovation have always been the key to driving industry development. In recent years, with the increasing awareness of environmental protection and the demand for efficient production, the field of papermaking defoamers has also witnessed many new developments and technological innovations.

Faced with increasingly strict environmental regulations, the development of environmentally friendly defoamers with low toxicity, low VOC, and biodegradability has become a consensus in the industry. By improving the chemical structure and using natural or renewable raw materials, researchers have successfully developed a series of environmentally friendly defoamers, such as polyether defoamers based on vegetable oil and modified starch defoamers. These products not only have excellent defoaming performance, but also reduce negative impacts on the environment.

With the rapid development of technologies such as the Internet of Things and big data, the application of intelligent additive systems in the paper industry is becoming increasingly widespread. By monitoring the foam in the pulp in real time, the intelligent system can automatically adjust the amount of defoamer added to achieve accurate control, which not only avoids the waste caused by excessive addition, but also ensures the optimization of defoaming effect.

Traditional defoamers mainly focus on eliminating foam, while modern papermaking processes put forward more requirements for defoamers, such as improving the fluidity of pulp, strengthening the strength and whiteness of paper, etc. Therefore, the research and development of multi-functional defoamers has become a new trend. Such defoamers can not only effectively eliminate foam, but also improve the pulp performance and paper quality to a certain extent.

The introduction of nanotechnology has brought revolutionary changes to paper defoamers. The dispersion and stability of defoamer can be significantly improved by modifying the defoamer with nano particles, so that it can act more efficiently on the foam system. In addition, nanoscale defoamers can also form a protective layer on the surface of paper, enhancing its waterproof, oil resistant and other properties.

In the future, the development of papermaking defoamers will pay more attention to environmental friendliness, efficiency, and intelligence. With the continuous advancement of materials science, nanotechnology, and information technology, the future development of papermaking defoamers will definitely get better and better.
