Paper Machine Foam Control Expert: Chemi Tech's Efficient Defoamer Solutions

On the paper machine, foam is a silent disruptor. It lurks in the stock, white water systems, and size press, causing not only holes and spots on the paper sheet but also poor drainage, frequent breaks, slowed production pace, and increased energy costs. Achieving stable and efficient foam control is a critical challenge for paper mills aiming to enhance quality and profitability.

Addressing these pain points directly, Chemi Tech leverages deep industry expertise to develop a series of high-performance defoamers for papermaking. Our solution goes beyond mere chemical addition; it is a systematic service based on a thorough understanding of the entire papermaking process, from diagnosis to continuous optimization.

Our core solution is a three-step process: First, our technical engineers conduct on-site assessments to pinpoint the exact source of foam—whether it originates from the stock, chemical reactions, or system design. Second, based on foam characteristics and process conditions, we select the most compatible Chemi Tech defoamer. Our products are designed for rapid bubble breaking, persistent foam suppression, and resistance to high temperatures and shear, with excellent system compatibility that avoids affecting pulp color or subsequent processing. Finally, we develop a scientific addition program, identifying optimal injection points and dosages, and ensure long-term effectiveness through online monitoring and regular follow-ups.

The value of this approach is proven in practice. A specialty cultural paper producer in East China faced persistent issues with sheet defects and web breaks caused by foam in the dryer section, experiencing several unplanned shutdowns monthly. After Chemi Tech's intervention, analysis of the white water system led to the recommendation of a dedicated silicone-based compound defoamer, with dual-point addition at the white water tower and headbox. Following implementation, sheet appearance improved significantly, the break rate dropped by over 70%, sheet formation was enhanced, and defoamer consumption was reduced by approximately 15% compared to the previous program, achieving dual optimization of quality and cost.
