Product Introduction

The main applications of polyacrylamide in the paper industry are as follows:
1. Improve the retention rate of additives and dyes to reduce the loss of raw materials and environmental pollution;
2. Improve the dry strength and wet strength of paper;
3. As a dispersant for long fiber papermaking;
4. Increase the stability of emulsion (or pulp liquid);
5. Binder for paper-coated pigments;
6. Paper finishing agent;
7. Paper industry wastewater treatment
Papermaking dispersant
Adding polyacrylamide dispersant during the papermaking process can effectively prevent fiber agglomeration and improve the uniformity of paper. The company's papermaking dispersants can be dissolved within 60min. Low dosage can promote good dispersion of papermaking fibers and excellent paper forming effect, improve pulp uniformity and paper softness, and can also increase paper strength properties. . It is suitable for all kinds of toilet paper, napkins, facial tissue and other household paper and other tissue paper, etc. It can completely replace PEO in some paper mills.
Retention and Drainage Aid
Cationic retention and drainage aids can improve the retention of fibers, fillers, fine fibers and other chemicals, bring a clean and stable wet-end chemical environment, save the consumption of pulp and various chemicals, reduce production costs, improve paper quality and Paper machine production efficiency. A good retention and drainage aid is a prerequisite and necessary factor to ensure smooth operation of the paper machine and good paper quality. It is necessary to select suitable products according to different conditions. Usually, high molecular weight polyacrylamide is more suitable for the pH of the system (the pH range is 4-10).
 
Usage and Dosage of Retention and Drainage Aid in Papermaking
1. The order of adding retention and drainage aids: cationic starch - neutral glue - cationic separation aid
2. Dosage: 100-200pm
3. Dilution concentration: 0.1-0.3%
4. Joining point: On the premise of ensuring uniform mixing with the paper material, it should be as close to the head box of the paper machine as possible.
 
Users can choose the best products according to the actual use conditions of different processes, and the company can also make on-demand production according to the specific requirements of users.
