The pulp and paper industry relies heavily on efficient processes to produce high-quality paper products. However, foam generation is a persistent challenge throughout various stages, from pulping and papermaking to coating and wastewater treatment. Uncontrolled foam can lead to significant operational issues, including reduced production rates, defects in the final paper product, increased chemical consumption, and equipment malfunctions. As a dedicated supplier of specialty chemicals, NINGBO INNO PHARMCHEM understands these critical needs and offers advanced defoaming solutions designed to optimize your manufacturing processes.

Foam in the paper industry arises from a complex interplay of materials like cellulose fibers, sizing agents, fillers, pigments, and various chemical auxiliaries, all of which can reduce surface tension and stabilize air bubbles. In pulping, especially during black liquor washing, the high concentration of organic compounds and surfactants creates substantial foaming. Similarly, during papermaking, the circulation of white water, combined with the addition of additives like sizing agents and retention aids, inevitably leads to air entrapment. Paper coating processes also face foam issues due to the formulation of coatings with pigments, binders, and other surfactants.

Effective foam control is crucial for maintaining product quality and operational efficiency. Defoamers act by destabilizing foam bubbles, either by preventing their formation (antifoams) or by breaking down existing foam. This is achieved through the introduction of specific chemical agents that possess lower surface tension than the foaming medium, allowing them to spread across the bubble film, thin it out, and ultimately cause it to collapse.

At NINGBO INNO PHARMCHEM, we provide high-carbon alcohol emulsion defoamers, such as our XPJ330 model, specifically engineered for the demanding requirements of the paper industry. These defoamers are renowned for their ability to efficiently remove air bubbles (80-90% efficiency), reduce moisture content, and improve key paper characteristics like smoothness and void rate. For manufacturers looking to buy paper coating defoamer online, our products offer a compelling combination of performance and value. We are a leading defoamer supplier in China, committed to providing reliable and cost-effective solutions.

Implementing the right defoamer can bring about substantial improvements. For instance, in white water systems, our antifoam agents ensure continuous foam suppression, preventing issues that can affect paper formation. When dealing with rosin sizing agents, our specialized defoamers help maintain process integrity. Furthermore, for applications involving latex paints and emulsions, these defoamers are indispensable for achieving a smooth, defect-free finish. By choosing NINGBO INNO PHARMCHEM, you are partnering with a manufacturer dedicated to your success, offering competitive pricing and expert support to help you how to reduce foam in paper production.
