Application of defoaming agent in papermaking industry
What are the functions of special defoamers in the papermaking industry? Why do we need to use defoamers when making paper? The following article will give you a brief introduction.
Special defoamers for papermaking are now standard in the papermaking industry, and almost many paper mills will use defoamer products. During papermaking, foaming will occur during the pulping process, and the foam will affect the quality of the paper, and the more foam accumulates, the more it will affect the efficiency of papermaking.
At this time, the special defoamer for papermaking is a solution specifically for the foam generated during papermaking. It can effectively remove all the foam on the surface during pulping without affecting the quality of the paper. Special defoamers for papermaking are composed of a variety of organic hydroxyl compounds, synergists, fatty acid ethers and lipids, etc., with strong defoaming and anti-foaming functions, without mineral hydrocarbons, which is beneficial to environmental protection, and has good compatibility with the foaming medium; the effect is stable during the storage period.
Instructions on the dosage of defoaming agent for papermaking: Add the defoaming agent directly into the foam system. The recommended dosage is 0.05%~0.3%. The final dosage can be added according to your own experimental results.
