Precision Solution for Papermaking Fiber Defoaming: Chemi Tech's Efficient Approach

Foam generated during the fiber processing stage is a common yet challenging issue in paper production. This foam not only reduces the consistency of stock concentration, affecting uniform fiber distribution and leading to pin holes or poor formation in paper, but also occupies effective equipment volume, lowering the efficiency of washing, screening, and bleaching. It can even cause operational failures like tank overflow and reduced pump efficiency, directly hindering production progress and increasing energy consumption.

The market commonly faces pain points such as short-lived defoamer effectiveness, adverse impacts on stock properties or finished paper brightness after addition, and insufficient stability under complex process conditions. Addressing these needs, Chemi Tech, through in-depth technical research, offers an efficient defoaming solution specifically designed for the papermaking fiber process.

The core of our solution lies in precise matching. First, by analyzing your specific stock composition, pH, temperature, and process speed, we select the most suitable defoamer type. Chemi Tech defoamers utilize specially modified polyethers and silicon-based materials, offering excellent dispersibility and persistence. They rapidly penetrate the foam film and destabilize it, achieving instant bubble breaking and long-term foam suppression.

The implementation steps are clear and efficient: Step one, on-site diagnosis and foam sample analysis to identify the primary causes of foam. Step two, provide samples for laboratory and machine trials to verify defoaming performance and system compatibility. Step three, determine the optimal addition point and dosage based on trial data, typically recommending continuous dosing at the pulper or before the screens. Step four, provide full-process technical follow-up to optimize parameters for consistent results.

We served a producer specializing in high-grade cultural paper. Due to the use of some recycled fibers and specific additives, the company experienced severe foam accumulation in the pulping and cleaning stages, requiring manual defoamer spraying multiple times per hour, with occasional paper surface defects. After adopting Chemi Tech's customized defoaming solution, which involved injecting our defoamer at key points via an automatic dosing system, foam was controlled immediately and consistently. Production resumed continuous and stable operation, paper formation improved significantly, while overall defoamer consumption was reduced by approximately 60%, yielding substantial economic benefits.

Choosing Chemi Tech means selecting not just a product, but a reliable support system to ensure smooth papermaking processes and excellent quality. We are committed to helping you overcome foam challenges and achieve cost reduction and efficiency improvement with our professional technology.
