  • 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 »

  • Defoamer for lubricating oil
    by admin on 11-27-2019

    The emergence and impact of foam   Foaming of lubricants is a highly undesirable phenomenon. The strong mixing of the foam with the air enhances the oxidation reaction, causing cavitation and insufficient oil delivery in the circulation system, even leading to unlubrication. Such as internal comb... Read more »

  • Reasons and solutions for defoaming of foam concrete
    by admin on 10-29-2019

    Reasons for defoaming of foam concrete: No.1   The foaming agent has poor foam stability. The main reason for this is that the foaming agent we use uses a low-grade surfactant without using a foam stabilization measure, which causes the foam to disappear too quickly. No.2  No slurry stabilizer ... Read more »
