  • Defoaming Features of Defoamer
    by admin on 12-04-2019

    Defoaming Features of Defoamer (1) The defoamer reduces the local surface tension of the foam liquid film and defoams. Because the surface tension of the defoamer droplets is lower than the surface tension of the foam liquid film, after the defoamer is added to the foam system, the defoamer drop... Read more »
