Just as important is the prevention of foam in processes such as printing, pumping, cooling and lubrication. Defoamers or antifoamers, which destabilize foams or prevent their formation, are used here. Certificate courses for successful and reliable measurements. DSA Inkjet. Your search term.

Foam Foam is the union of two phase systems consisting of gaseous bubbles which are separated by liquid lamella liquid foam or solid walls solid foam.
Foams: Fundamentals and Applications in the Petroleum Industry
Background When gas bubbles are present in a surfactant solution, surfactant molecules adsorb at the surface of the bubble and reduce the surface tension between the bubble and the volume phase. Significance Foam is very important in industry. Measuring methods selection Foamability measurement: A sample is foamed, e. After foaming, the height of the foam achieved is determined.
Foams Stabilized by In-Situ Surface-Activated Nanoparticles in Bulk and Porous Media - OnePetro
Foam stability measurement: The foam height is observed for a sample which has been foamed in a defined manner. The rate of decay of the foam can be evaluated on the basis of different parameters. Foam structure analysis: Foam is video-recorded using a special prism for achieving a two-dimensional cut through the foam structure.
The video is analyzed by software in order to calculate the number of bubbles per area as well as the bubble sizes and their statistical distribution. Conductivity measurement determination of liquid content : The liquid content of the foam can be determined based on a comparison of the conductivity of the starting solution and the foam formed.
