Effective foam control is paramount in the pulp and paper industry, and the correct application of defoamers is key to achieving desired results. NINGBO INNO PHARMCHEM CO.,LTD. provides high-performance silicone defoamers, and this guide outlines best practices for their application to ensure maximum efficiency, optimal pulp quality, and operational safety.

Our silicone defoamers are designed for direct addition into the pulping process. The recommended method of application involves using a metering pump to directly introduce the product into the head groove of the pulp washer or the outlet of a CX sieve pulp machine. This precise dosing ensures that the defoamer is distributed effectively within the system, addressing foam where it is most prevalent. The typical consumption rate is between 0.3 to 0.8 KG of defoamer per ton of dry pulp, though this can vary based on specific process conditions, the intensity of foaming, and the type of pulp being processed. It is always advisable to conduct small-scale trials to determine the optimal dosage for your particular operation.

When using our silicone defoamer for pulping, storage and handling are important considerations. The product is supplied in 200KG plastic buckets or IBC ton drums and should be stored at room temperature in a dry, well-ventilated area. It is important to protect it from freezing. When stored correctly, the product remains valid for one year, ensuring its efficacy for extended periods. As a non-hazardous chemical defoamer, it poses minimal risk during handling, but standard industrial hygiene practices should always be followed.

For those focusing on improving pulp quality, utilizing the defoamer’s inherent properties during pulp washing is key. The enhanced dehydration and improved washing efficiency achieved by our pulp washing defoamer mean that contaminants are more effectively removed. This not only leads to a cleaner pulp but can also reduce the reliance on secondary washing steps or additional chemicals, contributing to both cost savings and a more sustainable process. For operations involving specialized pulps like sulfite bleached wood pulp or alkali rice straw pulp, understanding how to integrate the defoamer into the washing cycle can significantly boost the final product's purity.

When integrating our defoamers into the paper making process, consider the dynamic nature of foam generation. Factors such as machine speed, water chemistry, and the types of additives used can influence foaming levels. It is often beneficial to maintain a consistent, low-level dosage rather than applying large amounts intermittently. This proactive approach ensures continuous foam suppression, leading to more stable operations and consistently high pulp quality. NINGBO INNO PHARMCHEM CO.,LTD. is committed to supporting our clients with technical expertise to ensure they achieve the best possible results from our products.

By adhering to these application guidelines, manufacturers can harness the full potential of our silicone defoamers, achieving superior foam control, enhanced pulp quality, and greater operational efficiency in their pulping and papermaking activities.
