Pulp washing is a vital stage in paper manufacturing, aimed at removing impurities and residual chemicals from the wood pulp. During this process, significant amounts of foam can be generated, which not only hinders the washing efficiency but can also lead to carry-over of undesirable substances to the paper machine, negatively impacting the final paper quality. The strategic use of defoamers, such as our mineral oil-based flocculation defoamer, is crucial for optimizing this stage.

Our flocculation defoamer is specifically designed to provide strong defoaming action in pulp washing systems. Its formulation ensures excellent stability and compatibility, even in challenging environments, allowing it to effectively control foam and entrained air. By suppressing foam, the defoamer enhances the drainage of wash liquors, allowing for more thorough removal of impurities from the pulp. This improved washing efficiency is directly linked to a cleaner pulp, which is the foundation for higher-quality paper.

A key benefit of using our defoamer in pulp washing is the reduction of carry-over to the paper machine. When foam is not adequately controlled, it can carry over dissolved or suspended solids, including residual chemicals and fines, into the subsequent stages of paper production. This carry-over can lead to processing issues, increased chemical consumption, and defects in the final paper sheet, such as spots or reduced brightness. By effectively managing foam, our defoamer minimizes this carry-over, contributing to a cleaner system and a more consistent paper product.

Moreover, the long-lasting effect of our defoamer ensures continuous foam control throughout the pulp washing process. This sustained performance is vital for maintaining consistent operational efficiency and preventing unexpected foam-related disruptions. The mineral oil base of our product provides a robust solution that is superior to many traditional defoamers, offering reliable performance across a range of conditions.
