Description

Technical Field

[0001] The utility model relates to the technical field of surface and interfacial tension testing, in particular to a platinum ring calibration tool for surface and interfacial tension testing. Background Technique

[0002] A surface and interfacial tensiometer is mainly used for measuring the interfacial tension of liquid-liquid or the surface tension of liquid-gas. Among them, common interfaces include: gas-liquid interface, gas-solid interface, liquid-liquid interface, liquid-solid interface, solid-solid interface. At present, surface and interfacial tensiometers can be divided into the platinum ring method and the platinum plate method according to different test principles. Among them, the platinum ring is made of platinum wire with a diameter of 0.37 mm and a circumference of 60 mm. During the test, the platinum ring is first immersed 2-3 mm below the liquid surface (or the interface between two immiscible liquids), and then the platinum ring is slowly lifted upward. A film will be formed between the ring and the liquid surface. The film will have a downward pulling force on the platinum ring. Measure the maximum force value exerted by the film on the ring during the entire process of lifting the platinum ring, and then convert it into the true surface (interface) tension value. The platinum plate method is that when it is sensed that the platinum plate is immersed in the liquid to be measured, the platinum plate will be affected by the surface tension around it, and the surface tension of the liquid will pull the platinum down as much as possible. When the surface tension of the liquid and other related forces reach equilibrium with the balancing force, the sensing platinum plate will stop immersing into the liquid. At this time, the balance sensor of the instrument will measure the immersion depth and convert it into the surface tension value of the liquid.

[0003] Among them, in the platinum ring method, calibrating the platinum ring is an important process for measuring the surface and interfacial tension. At present, the calibration of the platinum ring in the prior art is like the Chinese utility model with the patent publication number: CN202974804U and the name: A Platinum Ring Calibration Component, which includes a calibration base and a calibration press frame used in cooperation with the calibration base. The calibration base is a resin shaft with stepped shafts on both sides. The diameter of the stepped shaft on one side is equal to the diameter of the circular ring at the head of the platinum ring. The calibration press frame includes a pressing piece, which is semicircular, and the diameter of the semicircle of the pressing piece is equal to the diameter of the circular ring at the head of the platinum ring. The calibration press frame also includes a vertical rod and a handle. There are three vertical rods, and these three vertical rods are arranged in an array on the pressing piece. These three vertical rods are connected by a cross bar, and the handle is fixed above one vertical rod. It uses manual operation of the calibration press frame, which is affected by hand tremors and depends entirely on the skill level of the operator.
