Overview
The domestically produced water droplet angle measuring instrument refers to the angle formed when a liquid droplet is dropped on a solid horizontal plane, and the gas-liquid interface and the two tangent lines of the solid-liquid interface sandwich the liquid phase at the solid liquid gas three-phase boundary point on the surface of the solid. It is mainly used to measure the contact angle of liquids with solids, that is, the wettability of liquids with solids, and can measure the contact angle of various liquids with various materials.
Product Details
Domestic droplet angle measuring instrumentOverview
Contact angle refers to the tangent line of the gas-liquid interface at the intersection of gas, liquid, and solid phases. This tangent line forms the angle θ between the liquid side and the solid-liquid boundary line. Contact angle measurement is currently the main method for surface performance testing.
The principle of optical imaging is adopted, and the equipment uses image contour analysis to measure the surface contact angle, wetting performance, interfacial tension, forward and backward angles, surface energy and other properties of the sample. The equipment adopts a fully automatic liquid inlet device, which has high cost-effectiveness, strong scalability, comprehensive functions, and can meet various conventional measurement needs. Currently, it has been widely used in many universities, colleges and enterprises.
Domestic droplet angle measuring instrumentapplication
Contact angle measuring instruments are widely used in various industries, such as mobile phone manufacturing, glass manufacturing, surface treatment, material research, chemical engineering, semiconductor manufacturing, coatings and inks, electronic circuits, textile fibers, medical biology, etc. Contact angle measurement has become an important instrument for evaluating surface performance.
