Paper Making Dispersant

Short Description:

Paper making dispersant could prevent the aggregation of fibers and improve the uniformity of paper. With low dosage, it could faciliate the good dispersion of fiber and the good shape of paper, improve the uniformity of paper pulp and the softness of paper, and enchance the strength of paper.It is widely used the production of toilet paper, napkin, tissue and other tissue paper.

Papermaking dispersants play a key role in the papermaking process. They ensure high-quality paper production by dispersing fibers, improving slurry stability and enhancing fiber and filler separation.

Function:

Polyacrylamide is often used as a dispersant in papermaking. Polyacrylamide is a water-soluble organic polymer. It dissolves readily in water and forms a highly viscous liquid. Low addition levels are beneficial to tissue paper production. It requires good fiber dispersion, excellent paper-forming effect, improved pulp uniformity and paper softness, and at the same time improved paper strength. The effective storage period is 2 years. When used in paper coatings, it can disperse brittle papers and cause chalking. At the same time, it can improve the tensile strength and dry and wet strength of paper products and save paper pulp.

Advantages:

Using polyacrylamide as a dispersant for papermaking can increase the viscosity of paper pulp, disperse fibers and fillers, and make the pulp uniform, smooth, flexible and non-porous; it is not easy to break paper and produce powder during papermaking. Copy performance is stable. It can improve the retention rate of fibers and fillers, save pulp, increase the paper output rate by 15%, significantly increase the vehicle speed, and is suitable for all types of paper. The beating degree can be appropriately reduced to save electric energy. And it can improve the tensile strength and dry and wet strength of paper products.

Performance:
1. Fiber dispersion: Dispersants help disperse fibers evenly and avoid the formation of fiber clumps, thereby improving paper quality. In particular, the dispersion mechanism of PAM is because the PAM molecular chain contains carboxyl groups, which can reduce surface tension and help water wet the solid. This is particularly beneficial for the dispersion of fibers, fillers, etc. in water. When PAM is added to the slurry, it can form a bimolecular structure on the surface of the fiber and filler, and the outer dispersant has a strong affinity with water. This increases the extent to which solid particles, such as fibers and fillers, are wetted by water. Solid particles such as fibers and fillers are kept separated due to electrostatic repulsion, achieving good dispersion effects.

2. Improve slurry stability: The use of dispersants can improve the stability of slurry and reduce the risk of slurry precipitation and equipment clogging during the papermaking process.

3. Separation of reinforcing fibers and fillers: In papermaking, filler substances are usually added, and dispersants help separate fibers and fillers to ensure uniform distribution.

The polyacrylamide produced by Hengfeng Chemical will match customer needs according to the needs of different scenarios, creating a high-quality product supply chain for paper product factories.

For example, the following common paper production plays an excellent role.
Book and newspaper manufacturing: In book and newspaper manufacturing, dispersants help improve paper smoothness and printing quality.
Packaging industry: In the manufacturing of packaging paper, dispersants can improve the quality of the paper and make it more suitable for printing and packaging.
Tissue paper: In the manufacture of toilet paper, household paper, and kitchen paper, dispersants help to improve the softness and water absorbency of the paper.
