Application of Polyethylene Glycol in Paper Industry

Polyethylene glycol 200(PEG 200) is mainly used as surfactant and dispersant in paper industry. Its efficacy mainly includes the following points:

1. Dispersibility: Polyethylene glycol 200 has good dispersibility, which can make the fibers and filler particles in the slurry better dispersed in water, and improve the fluidity and coatability of the slurry.

2. Surface activity: Polyethylene glycol 200 has certain surface activity, which can improve the hydrophilicity and lipophilicity of paper surface, improve the printing performance of paper and the adhesion of paint.

3. Thickening: Polyethylene glycol 200 can increase the viscosity of the coating solution, which makes it easier to coat and evenly disperse on the paper.

4. Protective colloid: Polyethylene glycol 200 can be used as protective colloid to prevent pigment particles from settling in the coating solution and ensure the uniformity of coating.

5. Improve paper properties: Polyethylene glycol 200 can improve the strength, flexibility and tensile properties of paper, thus improving the overall quality of paper.

6. Energy saving and emission reduction: PEG 200, as an environmentally friendly surfactant, can reduce the amount of paint and wastewater discharge, which is beneficial to energy saving and emission reduction.

In a word, PEG 200 plays an important role in the paper industry, which can improve the quality and performance of paper and improve the coating effect. At the same time, as an environmentally friendly additive, PEG 200 is helpful to realize the sustainable development of paper mills.
