Paper industry defoamer: the key to improving paper quality

Paper, as an indispensable item in our daily life and work, its quality directly affects our use experience. In the papermaking process, defoamer plays a key role in improving paper quality. With its unique properties and wide applications, defoamer in the paper industry has solved the foam problem in the paper making process and promoted the efficient development of the paper industry.



The defoamer in paper industry has the characteristics of fast defoaming and lasting defoaming. In all aspects of papermaking, such as pulp preparation, paper making, coating and other processes, due to the mixing of fibers, the addition of chemicals and the mixing of air, a large number of foams will be produced. If these foams are not eliminated in time, they will have a serious impact on the quality of the paper. The paper industry defoamer can quickly penetrate between the foam, reduce the surface tension of the foam, and make the foam burst quickly. At the same time, its special molecular structure can form a protective film in the system to prevent foam from being produced again and achieve a long-lasting foam suppression effect.


In the process of pulp preparation, the role of defoamer is particularly important. The fibers in the pulp will mix with a lot of air during the mixing process, forming foam. These foams can affect the concentration and fluidity of the pulp, leading to problems such as clogging during transportation and storage. The defoamer in the paper industry can quickly eliminate the foam in the pulp, so that the concentration of the pulp is more uniform, the fluidity is better, and the quality and production efficiency of the pulp are improved. For example, in the pulp production line of a large paper mill, after the use of defoamer, the pulp delivery speed is increased by [X]%, and the quality stability of the pulp is also significantly improved.



The paper making process is the key link to determine the quality of paper, and the defoamer plays an indispensable role in it. In the process of paper making, the existence of foam will cause the paper to appear holes, spots, uneven thickness and other quality problems. The paper industry defoamer can effectively eliminate the foam in the paper making process, so that the fiber distribution of the paper is more uniform, the thickness of the paper is more consistent, and the surface is more smooth and flat. The paper produced in this way has better strength, evenness and printability, and can meet the needs of paper in different fields. For example, in the production of high-grade writing paper and printing paper, the use of defoamer can make the paper whiter, better gloss, and more clear printing effect.



Coating is an important process to improve the surface properties of paper, and defoamer also plays an important role in it. During the coating process, the additives and stirring in the coating will produce a large number of bubbles, which will affect the coating uniformity and adhesion of the coating, resulting in defects such as bubbles and orange peel on the surface of the paper. The paper industry defoamer can quickly eliminate the foam in the coating process, so that the coating can be evenly coated on the surface of the paper, and improve the adhesion and wear resistance of the coating. For example, in the production of coated paper and whiteboard paper, the use of defoamer can make the coating of the paper more smooth and delicate, and the color after printing is more bright and full.


With its excellent performance and wide application, defoamer in the paper industry has become a key force to improve paper quality. It not only solves the foam problem in the papermaking process, improves production efficiency, but also improves the quality and added value of paper. With the continuous development of the paper industry and the continuous improvement of paper quality requirements, the paper industry defoamer will continue to innovate and improve, providing more powerful support for the sustainable development of the paper industry. Behind every piece of high-quality paper, it is inseparable from the silent pay of defoamer in the paper industry.
