Abstract

The invention provides a contact angle measuring instrument which comprises a mounting structure (10), a light source (20), an imaging device (30) and a loading structure (40). The light source and the imaging device are arranged at intervals on the mounting structure. The loading structure is movably arranged between the light source and the imaging device in the horizontal direction. The loading structure (40) comprises an objective table (41) used for placing samples and also comprises an angle adjustment structure (42) arranged below the objective table (41). The angle adjustment structure (42) enables the objective table (41) to be angle-adjustably arranged between the light source (20) and the imaging device (30). By the technical scheme, problems of a contact angle measuring instrument in the prior art, such as difficulty in image analysis in later stage and large measurement error, can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of contact angle measurement, in particular to a contact angle measuring instrument. Background technique [0002] At present, the contact angle measuring instrument is mainly used to measure the contact angle of liquid on various solid materials, and it plays a very important role in the scientific research and production of petroleum, printing and dyeing, medicine, spraying, mineral processing and other industries. The existing contact angle measuring instrument is mainly composed of automatic rotating platform, CCD camera, advanced zoom lens, automatic and precise sample feeding, automatic image analysis system, all-electric three-dimensional platform and other parts. The above instrument is mainly suitable for the measurement of the liquid contact angle on the sample (such as thin slice) whose upper and lower end surfaces are parallel. However, the above-mentioned instruments have strict requirements fo...
