What is the function of defoamer for paper tube adhesive

Paper tube adhesive is a type of adhesive specifically used for bonding paper tubes (paper cores), usually with good adhesion performance and water resistance to ensure the structural stability and durability of paper tubes. It is usually used to manufacture products such as tissue roll cores, toilet paper cores, packaging paper tubes, etc. The addition of defoamers for paper tube adhesive plays a crucial role in ensuring the quality of the adhesive and the performance of the final product. As a key component in the formulation of paper tube adhesive, defoamers are designed to treat the bubbles generated in the adhesive solution to ensure the bonding effect and stability of the paper tube.

There may be many reasons for producing a large amount of foam in paper tube glue.

1. In the process of preparing paper tube glue, too fast mixing or stirring speed of glue solution may introduce a lot of air, thus forming foam in the liquid

2. If the surface of the equipment or container used in the preparation process is not clean, the residual grease or other dirt may also lead to the generation of foam.

3. If the formula of paper tube glue contains some surfactants or other ingredients, these ingredients may also cause a lot of foam during mixing or mixing.

The function of defoamer for paper tube adhesive:

4. Improve production efficiency: Defoamer effectively prevents the interference of foam in the production process, and improves the stability and efficiency of the production line.

5. Ensure product quality: Defoamer eliminates the existence of foam, enables paper tube glue to penetrate and bond paper tubes more evenly, and improves the quality and appearance of finished products.

6. Reduce the waste rate: By eliminating foam, defoamer can reduce the waste rate caused by foam interference in the production process, reduce resource waste and improve production efficiency.

High quality paper tube adhesive defoamers have the characteristic of having a small impact on the performance of the adhesive itself, and can be well compatible with other formula components without affecting the adhesive performance of the adhesive.
