As an important part of the traditional manufacturing industry, the paper industry often faces the problem of foam in the production process. Foam not only affects the fluidity and uniformity of pulp, but also may cause paper defects and reduce product quality. Therefore, the application of defoamers in the paper market is particularly important.

The existence of foam will interfere with the uniform distribution of pulp, resulting in uneven paper surface, even holes and spots. Defoamers can effectively eliminate foam, ensure the uniformity of pulp, and thus improve the quality of paper. Foam will lead to increased equipment failure and downtime in the production process, thus reducing production efficiency. The use of defoamers can reduce equipment failures, improve the stability and continuity of production lines, and thus enhance production efficiency. Foam will take away some pulp and additives, resulting in waste of resources. Defoamer can reduce the production of foam, reduce resource waste and improve production efficiency.

In the process of pulp preparation, defoamer is added to the pulp to eliminate foam caused by mixing and chemical reaction. On the paper machine, defoamer is sprayed on the pulp surface or added to the pulp to eliminate foam caused by water flow and mechanical action. In the process of papermaking wastewater treatment, defoamer is used to eliminate foam in wastewater to ensure the smooth progress of wastewater treatment.

With the improvement of environmental awareness and technological progress, defoamers in the paper market are developing towards green, efficient, and multifunctional directions. Green defoamers use environmentally friendly raw materials to reduce pollution to the environment; Efficient defoamers have faster defoaming speed and better foam suppression performance; Multi functional defoamers have other functions such as antibacterial and anti-corrosion to meet the needs of different papermaking processes.

In summary, the application of defoamers in the paper market is of great significance for improving paper quality, enhancing production efficiency, and reducing resource waste. With the continuous advancement of technology and increasingly strict environmental requirements, defoamers in the paper market will develop towards a greener, more efficient, and multifunctional direction.
