The paper machine is where the transformation from pulp slurry to finished paper occurs, a complex process highly susceptible to foam-induced disruptions. NINGBO INNO PHARMCHEM CO.,LTD. highlights the indispensable role of silicone defoamers in ensuring the smooth, efficient, and high-quality operation of paper machines.

Foam generation on a paper machine is a multifaceted issue. It arises from the chemical interactions of various wet-end additives like retention aids, sizing agents, and fillers, combined with the high-speed mechanical actions inherent in the process. This foam, if left unchecked, can lead to a host of problems. It negatively impacts the formation of the paper sheet, causing defects like pinholes, uneven thickness, and poor surface properties. Furthermore, entrained air and foam can reduce dewatering efficiency on the forming wire, slowing down the machine and increasing the energy required for drying.

Silicone defoamers are exceptionally well-suited to address these challenges. Their ability to quickly break down foam at the air-water interface ensures that the pulp slurry entering the forming section is free of disruptive bubbles. This leads to a more uniform sheet, improved retention of fines and fillers, and enhanced drainage. By ensuring cleaner systems, silicone defoamers contribute to reduced buildup on machine components, which can otherwise lead to operational issues and quality defects. We offer silicone defoamer paper making solutions that directly tackle these on-machine problems.

The benefits extend to energy consumption. Improved dewatering means less water needs to be evaporated in the drying section, leading to significant energy savings. This aligns with the industry’s push for reduced energy usage and a smaller carbon footprint. The low dosage effectiveness of silicone defoamers further enhances this benefit, providing high performance without introducing excessive chemical load.

NINGBO INNO PHARMCHEM CO.,LTD. provides a range of silicone defoamers that are specifically formulated for paper machine applications. These products are designed for compatibility with other wet-end chemistries and to maintain their effectiveness across the varying conditions found on a paper machine. Our experts work with clients to identify the optimal defoamer and application points – such as the white water system or stock chests – to achieve the best possible results.

In essence, silicone defoamers are not just an additive; they are a critical enabler of efficient and high-quality paper production. By investing in advanced silicone defoamer technology from NINGBO INNO PHARMCHEM CO.,LTD., paper manufacturers can significantly improve their machine runnability, paper quality, and overall operational economics, reinforcing their competitive edge.
