The introduction and characteristic analysis of dryer stripping agent

　　Due to the wider use of non-wood fibers, the increase in papermaking chemicals, and the increase in the proportion of secondary fibers used in papermaking, sticky tubes have become a common phenomenon in the papermaking process. Therefore, it seriously affects the normal operation of the paper machine and the quality of the finished paper, affecting the production efficiency. Here is an introduction to what is dryer stripping agent.

The new reagent has a good effect on solving the problem of drum adhesion, reducing the phenomenon of broken head and powder dropping in the drying part, and increasing the whiteness and smoothness of the paper. For example, for paper with a high degree of smoothness (aluminum foil liner, printing paper), the dryer stripper can control the appropriate roller adhesion to make the paper peel evenly.

Wax emulsion properties

Wax emulsion can be used as the main component of dryer stripping agent. No, anionic dewaxing agent is mainly used for dryer surface spraying or adding paper coating. In addition to the peeling (or lubrication) effect, it also has a good effect on changing the printability of the paper when it is used for coating. The cationic dewaxing agent combines with the fibers in the pulp through its own cationic charge. When the paper is dried in the dryer, the wax particles migrate to the surface of the paper after being heated and contact with the dryer, so as to achieve a good peeling effect. This release agent has wide adaptability. It can be added to the slurry, sprayed on the surface of the dryer, or used in combination with the two methods. In addition, the amount of release agent should be adjusted according to the speed of the paper machine. Dewaxing agent is mainly used in high-grade toilet paper, printing paper, aluminum foil paper, process weaving paper, high-grade wrapping paper and so on.
