The contact angle refers to the tangent of the gas-liquid interface made at the intersection of gas, liquid and solid, and the included angle between the tangent on the liquid side and the solid-liquid boundary θ, Contact angle measurement is the main method of surface property detection nowadays.
Application
1. Wetting behaviors such as spreading, penetration and absorption of liquid on the solid surface, and static contact angle is measured by drop method;
2. Measurement of advance angle, retreat angle, contact angle lag, rolling angle and dynamic contact angle of the material on the solid surface;
3. Continuous real-time research and process recording of absorbent materials, and analysis of contact angle curve with time;
4. Contact angle measurement of various special materials, such as powder, curved surface, superhydrophobic / superhydrophilic samples;
5. Test the contact angle of the material immersed in the liquid by the adhesion drop method;
6. The surface tension, polarity and dispersion components of various liquids were measured by hanging drop method;
7. Calculate the surface free energy of solid and analyze its polar dispersion component;
8. Analyze the adhesion work of the liquid on the solid surface, and evaluate the uniformity and cleanliness of the solid surface.
