Contact Angle Meter Contact Angle Measuring Instrument
Contact Angle Meter Contact Angle Measuring Instrument
Overview
Contact angle is the angle θ between the tangent line of the gas-liquid interface at the intersection of gas, liquid and solid phases, and the tangent line on the liquid side and the solid-liquid junction line.
The ZL-2823A basic contact angle meter uses the principle of optical imaging to measure the surface contact angle, wettability, surface energy and other properties of the sample by means of image profiling, which is extremely cost-effective and comprehensive, and can meet the conventional sample surface wettability measurement.
Applications
Contact angle measurement is used in a wide range of industries and has become an important instrument for assessing surface properties in areas such as mobile phone manufacturing, glass manufacturing, surface treatment, materials research, chemical and chemical engineering, semiconductor manufacturing, coatings and inks, electronic circuits, textiles and fibres, and medical and biological applications.
- Spreading, penetration, absorption and other wetting behaviour of liquids on solid surfaces, static contact angle measurement by the seat-drop method
- Forward angle, backward angle, contact angle hysteresis, rolling angle, dynamic contact angle measurements of materials on solid surfaces
- Continuous real-time study and process recording of absorbing materials, contact angle variation curve analysis with time
- Contact angle measurements of various special materials, e.g. powders, curved surfaces, superhydrophobic/superhydrophilic samples
- Contact angle testing of materials submerged in liquids by the attached drop method
- Suspended drop method for measuring surface interfacial tension and its polar and dispersive components for various liquids
- Calculation of surface free energy (Surface free energy) of solids and analysis of its polar and dispersive components
- Analysis of the Adhesion of liquids on solid surfaces and assessment of the homogeneity and cleanliness of solid surfaces
