The correct selection and reasonable application of papermaking defoamers are the key to ensuring the smooth progress of the papermaking process and stable product quality. This article will provide readers with practical guidance on selection principles, application techniques, and other aspects.

Selection principle:

Adaptability: Select the appropriate type of defoamer based on the characteristics of the papermaking process, raw materials, and production equipment.

Efficiency: Prioritize products with fast defoaming speed, long foam suppression time, and low usage.

Environmental friendliness: Ensure that the selected defoamer complies with environmental regulations and does not cause pollution to the environment.

Economy: Reasonably control costs while ensuring quality.

Application skills: Accurately grasp the amount and timing of adding defoamers, avoiding excessive or premature addition. Pay attention to the compatibility of defoamers with other papermaking chemicals to avoid adverse reactions. Regularly monitor and adjust the dosage of defoamers to adapt to changes in production conditions.
