With the continuous advancement of papermaking technology and increasingly strict environmental requirements, the research and development of new papermaking defoamers has become a hot topic of industry attention. A new type of papermaking defoamer utilizes natural polymer materials as substrates and develops papermaking defoamers with excellent biodegradability and environmental friendliness through modification or composite technology. Such defoamers can not only effectively control foam, but also promote the biodegradation of slurry to a certain extent.

Introducing nanoparticles (such as silica, alumina, graphene, etc.) into papermaking defoamer systems can significantly improve their dispersibility and stability, enhance their defoaming and anti foaming abilities. The introduction of nanomaterials can also endow defoamers with more functionality, such as improving the strength and water resistance of paper.

Combining intelligent material technology, develop defoamers that can automatically adjust their defoaming performance based on papermaking process conditions such as temperature, pH value, pulp concentration, etc. This type of defoamer can work efficiently under specific conditions, while maintaining low activity under other conditions, thereby reducing unnecessary consumption and environmental pollution.

The use of biosurfactants produced by microbial fermentation as the main component of papermaking defoamers has the advantages of being completely biodegradable, non-toxic, and harmless. Through genetic engineering and other methods, the defoaming performance of these biological surfactants can be further optimized to make them more suitable for complex papermaking environments.

In the future, the research and development of papermaking defoamers will pay more attention to the combination of environmental friendliness, efficiency, and multifunctionality. By applying new materials, processes, and technologies, we have developed greener, smarter, and more efficient paper defoamer products to meet the demand of the paper industry for high-quality, low-cost, and environmentally friendly defoamers.
