Description

technical field [0001] The invention relates to an on-line measuring device, more specifically, the invention relates to an on-line measuring device for surface tension, contact angle and density of high-temperature melt. Background technique [0002] In surface science, the study of melt surface tension and interfacial tension and the discussion of surface tension and interfacial tension measurement methods are of great significance both theoretically and practically. However, it is difficult to measure and observe the surface phenomenon of the melt under high-temperature conditions, and it is not easy to measure accurately. So far, the data of high-temperature surface properties are still very scarce. [0003] The static drop method is a method for studying surface phenomena. It naturally forms droplets on a horizontal substrate, and the shape of the droplets is directly related to the surface tension and density of the liquid. The stable equilibrium shape of the droplets ...

Problems solved by technology

When using the traditional static drop method to study the high-temperature characteristics of various melts such as metals and their compounds, inorganic materials or their mixtures, ordinary cameras are generally used to obtain photos of the stable equilibrium shape of the research object in a high-temperature molten state, and then measure the required Data, and then process the data through Bashforth and Adams calculation tables, and finally obtain high-temperature characteristics such as surface tension, density and contact angle, but the photos obtained by this method are easy to be distorted, and there are many human factors in the test process, so the accuracy of the data is largely Depends on the personal skills of the observer; the improved method is to input the photo of the stable equilibrium shape into the computer through the scanner, and analyze the high-temperature physical properties of the melt through software. This method has complicated procedures and takes time for each measurement. long
