提高泡沫稳定性的发明方法
使用机械分散机(Dispermat)混合疏水蛋白，SDS和纤维。分散机速度可调，但通常在实验中使用约3800rpm。研究泡沫体积随时间的变化。通过此设置，发泡在1分钟内达到最大水平。通过摄影监测泡沫体积的变化，其中每10秒拍摄照片。从照片图像中，确定达到50%气体体积(t50)和66%气体体积(t66)所需的混合时间。此外，测定达到的最大体积(Omax)。记录10分钟测量泡沫的塌陷率，而每1分钟拍摄照片。根据这些数据，可以估算泡沫的V /。 V /值描述当液体体积达到其初始高度的一半(排水量)时停止混合后经过的时间。
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).
