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.
Application:
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.
1. spreading, penetration, absorption and other wetting behaviour
of liquids on solid surfaces, static contact angle measurement by
the seat-drop method;
2. forward angle, backward angle, contact angle hysteresis, rolling
angle, dynamic contact angle measurements of materials on solid
surfaces;
3. continuous real-time study and process recording of absorbing
materials, contact angle variation curve analysis with time;
4. contact angle measurements of various special materials, e.g.
powders, curved surfaces, superhydrophobic/superhydrophilic
samples;
5. contact angle testing of materials submerged in liquids by the
attached drop method;
6. suspended drop method for measuring surface interfacial tension
and its polar and dispersive components for various liquids;
7. calculation of surface free energy (Surface free energy) of
solids and analysis of its polar and dispersive components;
Analysis of the Adhersion of liquids on solid surfaces and
assessment of the homogeneity and cleanliness of solid surfaces.
