In the paper industry, foam is an "invisible killer" that affects production efficiency and product quality. Defoamers for paper making mainly destroy the surface tension of foam to make it break and dissipate rapidly, so as to achieve the purpose of defoaming. Papermaking defoamer has become an indispensable chemical additive in modern paper industry by rapidly eliminating foam in pulp.

In the process of paper making, foam is easily formed inside and on the surface of the pulp, which affects the uniformity and quality of the paper. Defoamers can effectively eliminate these foam, reduce the formation of paper holes, and improve the strength and uniformity of paper.

In addition, the appearance of foam will lead to the decline of pulp fluidity, interfere with the uniformity of chemical mixing, and even block the equipment pipeline. The appearance of defoamer can quickly destroy the elastic film on the bubble surface, inhibit the regeneration of foam, and ensure the continuity of slurry transportation and molding. In addition, the appearance of foam is easy to cause waste of raw materials and equipment loss, which can lead to high costs if accumulated for a long time. Defoamers can directly save production costs by reducing foam retention time, reducing dehydration energy consumption and fiber loss.

Although papermaking defoamers are niche additives, they are one of the core technologies that ensure efficient and green production. In the future, with the increasing demand for environmental protection, the development of low toxicity and biodegradable defoamers will become an industry trend.
