Description

Technical Field

[0001] This utility model relates to the technical field of water droplet angle testers, and more specifically, to a user-friendly water droplet angle tester. Background Technology

[0002] The water droplet angle is defined as the angle between the gas-liquid interface and the solid-liquid interface at the solid-liquid-gas three-phase interface. It is a measure of the humidity of a solid surface, measured using most of the liquid droplets adhering to it. A low contact angle indicates high humidity (hydrophilicity) and easy adhesion to the surface, while a high contact angle indicates hydrophobicity, heavier organic contamination, or poor adhesion. The contact angle is the angle of contact between a liquid and a flat solid surface. It is determined by measuring the endpoint of the water droplet curve at the liquid-solid-gas junction and the contact point on the solid surface to analyze surface cleanliness. The contact angle is a measure of the humidity of a solid surface, measured using most of the liquid droplets adhering to it. A low contact angle indicates high humidity (hydrophilic or hydrophobic) and low surface energy.

[0003] When a water droplet angle tester is in actual operation, it mainly consists of four sets of mechanisms on top: a testing platform for placing objects, an injection mechanism for providing water droplets, an illumination mechanism for providing light sources, and an analytical device for analyzing and detecting the water droplet angle. These devices work together to form the entire water droplet angle tester. However, the arrangement of these devices also results in the water droplet angle tester occupying a lot of space. When these devices cannot be stored, it is not easy to move and transport the entire instrument. Therefore, a convenient water droplet angle tester is needed. Utility Model Content
