Surface sizing agent can eliminate the problem of paper fuzzing and powder loss
1. Reasonable control of beating. Properly increasing the beating degree increases the appearance area of the fibers, and adjacent hydroxyl groups combine to form hydrogen bonds, which not only increases the binding force but also improves the tightness of the paper sheet;
2. Innovate the dispersion of fillers between the front and back of the paper page, as well as the cross-section of the paper page;
3. Increase wet end additives, such as starch, dry strength agents, sizing agents, etc;
4. Utilize higher strength exterior sizing agents or increase the amount of sizing;
5. Improved the water filtration performance of the web paper material and the retention rate of micro fibers and fillers;
6. Innovate the pressing process, appropriately increase the pressure at the pressing section, and increase the paper tightness;
7. Innovate the drying process and strictly control the temperature curve (the temperature of the first few drying cylinders should not be too high, and appropriate drying cylinder stripping agents should be selected);
8. Increase the pressure of calendering, increase the tightness of the paper, and further compact the paper;
9. Reasonably control the moisture content of the paper.
