Description

technical field [0001] This patent discloses a device that uses an analytical balance as a weighing sensor, utilizes the existing upper tray or side-hanging tray structure of the analytical balance, and adds a set of lifting mechanisms to realize the measurement of interfacial tension, surface tension, and contact angle. Through this device, one instrument can complete the measurement of analytical balance weighing, density balance and surface / interfacial tension and contact angle under the weighing principle, so as to achieve the purpose of one machine with multiple functions. In the test method, the static platinum plate method technology based on the Young-Laplace equation correction and combined with the Wilhelmy plate method formula is used to dynamically test the surface tension, contact angle and interfacial tension values. The technology involved in this patent can be widely used in daily chemical, pesticide, petrochemical, surfactant research, fire protection, electri...
