Contact Angle is the tangent line of the gas-liquid interface at the intersection point of gas, liquid and solid. This tangent line has an Angle between the liquid and the solid-liquid boundary. The measurement of contact Angle is the main method for surface performance detection nowadays.
SDC-80 basic contact Angle measuring instrument adopts the principle of optical imaging to measure the surface contact Angle, smáčivost, surface energy and other properties of the sample by means of image profile analysis. The equipment has high cost performance, comprehensive functions and can meet the requirements of conventional sample surface wettability measurement.
aplikace
Contact Angle measuring instrument is widely used in various industries, in the mobile phone manufacturing, glass manufacturing, surface treatment, material research, chemical and chemical industry, semiconductor manufacturing, paint and ink, electronic circuits, textile fiber, medical biological and other fields, contact Angle measurement has become an important instrument to evaluate the surface performance.
