A METHOD FOR INCREASING FOAM STABILITY FIELD OF THE INVENTION

Mechanical mixer (Dispermat) was used to mix hydrophobin, SDS and fibers. Mixer speed was adjustable, but generally about 3800 rpm used in the experiments. Foam volume was studied as a function of time. Foaming reached the maximum level within 1 min with this set-up. The change of foam volume was monitored by photography,where pictures were taken every 10 s. From the photographic images, the mixing times required for reaching 50% gas volume (t50) and 66% gas volume (t66) were determined. In addition, the maximal volume achieved (Omax) was determined.Collapse rate of foam was measured with 10 min recording, whereas pictures were taken every 1 min. From these data V/ for the foam can be estimated. The V/ value describes the time elapsed after cessation of mixing when liquid volume reaches half of its initial height (drainage volume).
