Defoamer-for-Papermaking-Pulping

Detailed Description

In the process of papermaking and pulping, it is easy to produce foam. This can be due to factors such as fibers in the slurry, chemical additives, stirring, and temperature. The emergence of bubbles can bring many adverse effects:

Impact on production efficiency: foam may lead to poor slurry flow, hinder the normal operation of the equipment, and extend the production cycle.

Reduce paper quality: Foam may cause paper holes, uneven quality problems.

Increased costs: Foam can lead to waste of chemicals and increase production costs.

The Defoamer used in papermaking and pulping can effectively solve these foam problems. It generally has the following characteristics:

Strong defoaming ability: can quickly eliminate a large number of bubbles.

Long-lasting foam suppression: prevent foam from forming again for a long time.

Good compatibility with the slurry: it will not adversely affect the performance of the slurry and the subsequent papermaking process.

For example, in the chemical pulping process, the cooking liquid is easy to produce foam when it reacts with the fiber raw material, and the use of defoamer can ensure the smooth progress of the cooking process and improve the pulp yield.

In waste paper pulping, there may be a lot of foam in deinking and flotation, adding defoamer for paper pulping can improve the deinking effect and flotation efficiency.

In summary, the defoamer used in papermaking is of great significance for improving the efficiency of papermaking, ensuring the quality of paper and reducing the cost.
