Although paper defoamers play an important role in improving paper quality and production efficiency, their correct use and maintenance management cannot be ignored.

We need to accurately calculate the required dosage of defoamer based on the specific requirements of the papermaking process and the characteristics of the pulp. Avoid wasting or affecting paper quality due to excessive use, and ensure that the dosage is sufficient to effectively control foam. Choose the appropriate addition point, usually in the pipeline or storage tank before the pulp enters the paper machine. Add defoamer evenly through a metering pump or spraying device to ensure thorough mixing with the slurry. To ensure that the defoamer is thoroughly mixed with the slurry, it can be achieved by increasing the stirring intensity or extending the stirring time. Uniform mixing helps to improve the utilization and effectiveness of defoamers.

Regularly check the foam condition in the papermaking process and evaluate the effect of defoamer. Adjust the dosage or change the type of defoamer based on the test results to ensure optimal effectiveness. Keep the defoamer dosing equipment clean and in good operating condition. Regularly clean the dosing pipeline and nozzle to prevent blockage or leakage.

Establish detailed records of the use of defoamers, including dosage, addition time, effectiveness evaluation, and other information. By analyzing these data, the use strategy of defoamers can be optimized to improve production efficiency and paper quality. Train operators on the use and maintenance management of defoamers to ensure they are familiar with the correct operating procedures and precautions. This helps to reduce operational errors and malfunctions, and improve the stability and safety of the production line.

In summary, the correct use and maintenance management of papermaking defoamers are of great significance for improving paper quality and production efficiency. By following the correct usage techniques and maintenance management points, the optimal effect of defoamers can be ensured, contributing to the sustainable development of the paper industry.
