Method and the automatic device for continuous, non-invasive measurements of surface energy of the solids permanently submerged in liquids

摘要

automatic device for continuous, non destructive measurement of surface energy solids permanently submerged in liquids is suchit consists of a frame (3) with the system alignment with the vertical arm frame (3) is fitted a linear module (1), responsible for the measuring head (2) in the z axis.and on the basis of the framework (3) located system (7) for the automatic movement of the measurement vessel (5) together with the test sample (6) in the xy axes.in addition, on the frame (3) mounted digital camera with macro lens (4) for recording image drop rate to 30 frames / sec.together with the exact positioning of the camera (4) in xyz axes, as well as ou015bwietlacz on leds (8).a continuous, non destructive measurement of surface energy solids permanently submerged in liquids is suchthe air bubble to the surface of the sample pressing slowly and on this basis, defines the dynamic contact angle. r,then the air bubble is distracting from the substrate, and on this basis is measured second dynamic angle? and,what defines a hysteresis lsk =? a -? r and the surface tension of the liquid phase.
