Defoamer for Paper & Pulp

Defoamer for paper making is specially designed for foam in paper making process of paper industry. The foam problem of products in paper making process must be solved, otherwise it will seriously affect the stability of production and the quality of paper. In the paper making process, defoaming and foam suppression are the most important, as once the gas content in the pulp (by volume) reaches around 0.5~1.0%, it must be controlled, otherwise it will cause paper breakage, fluctuation of white water level, and pump frequency fluctuations. Sun Hong paper defoamer has a strong defoaming effect on white water. It can quickly remove the fine bubbles entrained between fibers, eliminate the foam floating on the surface of the pulp, and the air dissolved in the pulp. At the same time, it can eliminate the large bubbles on the water surface, eliminate the impact of bubbles on the process, avoid the formation of holes, reduce paper breakage, and prevent the overflow of the pulp storage tank, ensure the loss of fibers and wet end chemicals, and improve the uniformity of the paper, The quality has been greatly improved.

Defoamer for paper making is applicable to: coating and sizing of paper coating, coating coating, printing and pictorial paper after calendering, deinking and washing, defoaming and degassing in paper coating polymer system, Coated paper, pulp defoaming, paper surface sizing and pressing process, glue, defoaming in coating process, defoaming generated by deinking process, use of wet end of paper machine, degassing and defoaming in paper production, etc.
