Papermaking defoamer: a "magic weapon" to improve paper quality
With the progress of society and the improvement of living standards, people's requirements for the quality of paper are also increasing, and the papermaking process of high-quality paper is relatively more complicated. From the unit operation to the coating process (washing, pulping, drifting, dehydration, papermaking, sizing, coating, etc.), there are different degrees of foam. Foam is an important problem to be solved, otherwise it will affect the quality of the finished paper, so how to eliminate the foam? The answer is to add paper defoamer.
Paper pulping defoamer has a strong anti-foaming effect on foam, and can quickly become the fine analysis bubbles that are removed and entrained between fibers, eliminating the foam floating on the surface of the slurry and the air that can be dissolved in the pulp. At the same time, it can eliminate the large bubbles on the water surface, eliminate the influence of these bubbles on the process, avoid the formation of holes, reduce paper breakage,and ensure the loss of fiber and wet end chemicals, the paper has better uniformity, and the quality has been greatly improved.
The defoamer for paper making is used in alkaline pulping, alkaline pulping, papermaking pulping, bamboo pulp, sugarcane pulp, neutral pulping, pulp, papermaking pulping, pulp rinsing, screening, bleaching, water treatment, pulp industry The black liquor washing line is designed for foam control and is used in the production of plant fiber pulp. More of it is used in the production process, which can stably defoam and suppress foam.
The safest and most effective way to use this defoamer is to add a low-concentration dilute emulsion in a continuous or semi-continuous manner during the production process. In this way, it can not only prevent foaming but also prevent the problem of silicone oil pollution. If it is necessary to add enough silicone antifoaming agent at the beginning of the operation, it is necessary to avoid excess.
The above is the role of paper defoamer. For more foam solutions, feel free to contact us!
