1、 Application field
In the process of paper production, the fiber, filler and other solid phases in pulp suspension are easy to flocculate into clusters, which reduces the uniformity of paper and increases the loss. Papermaking fiber dispersant can form an electric double layer on the surface of solid fiber, and the outer dispersant and water form a thicker hydration layer, increase the charge repulsion between solids and improve the solid dispersion effect. It is an economic and effective additive to improve the uniformity of paper.
2、 Product characteristics
The product has the advantages of fast dissolution speed, high viscosity, low water insoluble content and easy degradation at high temperature, which promotes the dispersion of fibers, especially long fibers, adapts to the production of high-speed paper machine, and ensures low paper weight, thin paper, soft and uniform paper, etc.

4、 Method of use
1. The product is slowly and evenly sprinkled into the dissolution tank under stirring, configured as 0.05% ~ 0.1% solution, dissolved for 1 ~ 2 hours, the stirring speed is controlled at 40 ~ 60 rpm and the water temperature is lower than 50 ℃; 2. A 60 mesh screen shall be installed between the dissolution tank and the dilution tank to remove undissolved deposits; 3. According to the paper quality requirements, the diluted solution is sprayed and added to the front box of the paper machine with a quantitative pump or metering tank. Avoid using a high shear pump when pumping, so as not to cause shear degradation and affect the use effect.
5、 Packaging, transportation and storage
The product is packaged in paper plastic composite packaging, 25kg per bag or determined according to the needs of users, and the shelf life is 2 years.
