A large paper making enterprise encountered a serious foam problem when producing special high-grade cultural paper, which led to the decline of paper surface quality and affected sales. The enterprise attempted to use traditional defoamers, but the effect was unsatisfactory and the cost was high. After introducing a new type of highly efficient and environmentally friendly defoamer, the situation was significantly improved.

After a comprehensive evaluation of the production line, the technical team has decided to add a new defoamer in the pulp mixing stage and the first two processes of paper machine pressing. With unique molecular structure design, the defoamer can rapidly penetrate and destroy foam, and has good compatibility, without affecting the pulp performance and subsequent processes.

After implementation, the foam problem was effectively controlled, the surface finish of paper was significantly improved, the yield was increased by about 5%, and the energy consumption and chemical consumption in the production process were also reduced. More importantly, the defoamer meets environmental requirements and contributes to the green production of the enterprise. In the future, with the increasing demand for efficient, environmentally friendly, and low-cost production in the paper industry, as well as the continuous promotion of technological innovation, the market for paper defoamers will usher in a broader development space, especially those defoaming solutions that can combine digital and intelligent technologies, which will become the new favorite of the industry.
