Summary

Contact angle (Contact angle) refers to the tangent of the gas-liquid interface at the intersection of gas, liquid and solid, the angle between the liquid side and solid-liquid junction, contact angle measurement is the main method of surface performance detection.

SDC-500S automatic contact angle meter is a special device using appearance image analysis (Shape image analysis) method to measure sample surface contact angle, wetting energy, surface interface tension, surface energy, rolling (sliding angle), forward and backward angle and lag, multi-point automatic intelligent contact angle measurement and other performance. The equipment has a high degree of automation and can be fitted with automatic assembly line.

Application

Contact angle meters are widely used in various industry fields, in mobile phone manufacturing, glass manufacturing, surface treatment, has become an important instrument to evaluate surface performance, material research, chemical manufacturing, semiconductor manufacturing, coating ink, electronic circuits, textile fiber, medical biology and other fields.

(Some test functions need to be purchased with special accessories)

1. The wetting behavior of liquid spreading, penetration and absorption on the solid surface, and the static contact angle is measured by the seat drop method;

2. Measurement of the forward, backward, contact, backward, rolling and dynamic contact angles of the material on the solid surface;

3. Continuous real-time study and process recording of absorption materials, and curve analysis of contact angle with time;

4. Contact angle measurements of various special materials, such as powder, curved surfaces, hyper-hydrophobic / ultra-hydrophilic samples;

5. The contact angle test of the attachment droplet test material immersed in the liquid;

6. Suspension drop method measures the interface tension and its polarity and dispersion components of various liquid surface;

7. Computing solid surface free energy (Surface free energy), and its polar dispersion components;

8. Adadhesion work (Adhersion) of liquid on solid surface was analyzed to assess solid surface uniformity, cleanliness, etc.

contact angle meter are mainly composed of light source, injection unit, sample table, collection system and analysis software. The equipment adopts the principle of optical imaging.
