Retention Aid For Papermaking
On papermaking retention aids
The art of papermaking is related to people's livelihood, and the materials used are all important. Papermaking retention aids play a key role in the papermaking process.
Its properties also make fibers, fillers and other materials better retained on the paper. In the past, when papermaking was made, a lot of materials were lost, resulting in poor quality of paper and increased costs. Since the advent of papermaking retention aids, this disadvantage has gradually been eliminated.
Papermaking retention aids can make fibers and fillers adsorb each other and are closely connected by mechanisms such as charge neutralization and bridging. If when making paper, fibers float in the slurry, if they do not retain the agent, they will easily pass away with the flow of water. However, the retention agent is involved, the charge is neutralized, the fibers are close to each other, forming a network, and the filler must also be embedded in it, which greatly increases the retention rate.
Looking at its categories, there are natural things, which can be used as retention aids after refining; there are also synthetic agents, which are prepared according to scientific methods. Natural ones, such as starches, are derived from grains and modified to increase the retention effect; synthesizers, such as polyacrylamide, use chemical techniques to obtain products with different properties, which are suitable for different papermaking conditions.
Make good use of papermaking retention aids, and the quality of paper can be improved. If the fibers and fillers are well retained, the paper sheet has good uniformity and strength. And because of less material loss, the cost of papermaking can be reduced, which is of great benefit to the development of the paper industry. Therefore, papermakers should study the properties of papermaking retention aids in detail and make good use of them to make high-quality paper that meets the needs of the world.
