    The surface tension of the saponification produced during the pulping process is smaller than the surface tension of the black liquor produced by the cooking material, so that it exists in the surface layer of the black liquor and forms a film, which forms a foam under the action of air mixing, especially when The lower the concentration of black liquor, the more foam there is, which is the problem of foaming during papermaking.

    At this time, the intervention of papermaking defoamer is needed to effectively solve the foam problem. The papermaking defoaming agent is composed of various organic hydroxy compounds, synergists and fatty acid ether lipids, and has a strong defoaming effect and foam suppression time. Very long, mineral-free hydrocarbons, environmentally friendly, and compatible with foaming media.
