As an indispensable additive in the paper industry, papermaking defoamers have specific future development directions reflected in the following aspects:

1、 Environmentally friendly and sustainable, future paper defoamers will pay more attention to biodegradability to reduce environmental pollution. Developing new bio based or natural based defoamers that can quickly decompose in natural environments and reduce ecological risks. With the increasingly strict environmental regulations, defoamers with low volatile organic compound (VOCs) content will become mainstream. This type of defoamer can reduce the emission of harmful gases during production and use, making it more environmentally friendly.

2、 High performance and specialization, future paper defoamers will pursue higher defoaming efficiency to meet the demand of the paper industry for fast and stable defoaming. By optimizing the molecular structure and ratio of defoamers, their dispersibility and stability in pulp can be improved, thereby enhancing the defoaming effect. Develop specialized defoamers for different paper types and papermaking processes to meet the needs of different customers.

3、 Multifunctional and intelligent, future paper defoamers will develop towards multifunctionality, such as possessing antibacterial, antioxidant, anti-static and other functions. These multifunctional defoamers can not only solve the foam problem, but also improve the durability and safety of paper. By introducing intelligent sensors and control systems, the intelligent control of papermaking defoamers can be achieved. According to the foam situation in the production process, automatically adjust the amount and type of defoamer to achieve accurate defoaming and energy saving.

4、 Green production technology and circular economy, in the production process of papermaking defoamers, adopt green and environmentally friendly production technology, such as using renewable energy and reducing wastewater discharge. By optimizing production processes and equipment, energy consumption and pollution during the production process can be reduced. Promote the recycling and resource utilization of papermaking defoamers. For example, recycling and treating discarded defoamers for reuse in new paper production processes can achieve resource recycling and reduce waste emissions.

5、 Technological innovation and industrial upgrading, with the continuous emergence of new materials and technologies, future paper defoamers will pay more attention to technological innovation and industrial upgrading. For example, new technologies such as nanotechnology and biotechnology are used to develop more efficient and environmentally friendly defoamer products. Strengthen industry university research cooperation and promote the research and application of defoamer technology in papermaking. By collaborating with universities, research institutions, and other organizations, we aim to promote innovation and development in papermaking defoamer technology.

The future development direction of papermaking defoamers will pay more attention to environmental protection, high performance, multifunctionality, intelligence, as well as green production processes and circular economy. These directions will not only promote the transformation, upgrading, and sustainable development of the paper defoamer industry, but also provide strong support for the green development of the paper industry.
