1. The wetting behavior of liquids on solid surfaces, such as spreading, permeation, and absorption, is measured by the droplet method to determine the static contact angle;

2. Measurement of the advance angle, retreat angle, contact angle hysteresis, rolling angle, and dynamic contact angle of materials on solid surfaces;

3. Continuous real-time research and process recording of absorbing materials, analysis of contact angle variation curve over time;

4. Contact angle measurement of various special materials, such as powders, curved surfaces, superhydrophobic/superhydrophilic samples;

5. Contact angle test of materials immersed in liquid using the attachment drop method;

6. The suspended droplet method is used to measure the interfacial tension, polarity, and dispersion components of various liquids;

7. Calculate the surface free energy of solids and analyze its polar dispersion components;

8. Analyze the adhesion energy of liquids on solid surfaces, evaluate the uniformity and cleanliness of solid surfaces, etc.
