Abstract

The invention discloses a weighing principle based surface tension testing device and method of a sandwich effect, and belongs to the technical field of interface chemical analysis and test. The testdevice comprises a test sample cell, a test probe, a layered sample cell, a tee joint, a liquid inlet pump and a liquid storage pool, the layered sample cell is arranged in the middle portion of the test sample cell and divides the test sample cell into upper and lower accommodating areas, the layered sample cell includes a shunting tube through which the upper and lower accommodating areas are communicated in the test sample cell, the tee joint is communicated with the upper and lower accommodating areas in the test sample cell via upper and lower liquid inlet tubes respectively, the upper and lower liquid inlet tubes are provided with upper and lower liquid inlet valves respectively, the tee joint is also communicated with the liquid storage pool via a pipe, and the liquid inlet pump isarranged on the pipe. The surface tension value and dynamic adsorption time of the layers can be measured at the same time, the measuring precision is high, operation is convenient, and the device andmethod are worthy of popularization.

Description

technical field [0001] The invention relates to a sandwich effect surface tension testing device and method based on the principle of weighing, and belongs to the technical field of interface chemical analysis and testing. Background technique [0002] Surface tension is one of the important indicators to characterize the physical and chemical properties of materials. The surface tension is different, which plays a key role in adhesion, adsorption, foaming and other phenomena. From the perspective of testing principles, existing surface tension measurement methods are mainly divided into weighing principles (including the Wilhelmy Plate method and DuNouy Ring method), principles of image analysis methods (including the pendant drop method or stop-and-go method). drop method, rotating drop method), maximum bubble method (Max bubble pressure) and drop volume method, etc. [0003] Shanghai Solon's patents "A device for detecting milk SDS using surface tension" (Patent No. 201...
