Brief introduction As is known to all, nano material science and engineering has become a hot research topic in the world. In the study of surface modification of nano materials, the concept of wetting contact angle is often involved. The so-called contact angle is a drop of a drop on a solid horizontal plane, and the two tangent of the liquid gas interface and the solid liquid interface of the solid surface is the angle of the liquid phase. JC2000Y is convex and concave surfaces of the measurement of contact angle measuring instrument, mainly applicable to glasses yingpian, invisible glasses industry, glass tube, etc. various kinds of circular pipe industry. Japan HOYA optical procurement is the series of instruments. The JC2000Y series has a circular sample table, platform sample size is Phi 50mm Phi 81mm, thickness 5mm ~ 30mm. This instrument is mainly used to measure the shape of a circular convex or glass lens. Is now exported to Japan, South Korea, Malaysia, Thailand, Hong Kong, Taiwan and other countries and regions, such as the multinational group tag heuer optical (Hoya) will control the instrument is applied to the factory lens production testing. Technical parameter 1 instruments: Basic configuration: Sample pump, video capture card, manual CCD platform angle, CCD camera, continuous variable magnification optical system (made in China), samples were fixed platform, concave convex special image analysis system was used to measure the peristaltic plus Optional configuration: Manual + 15 DEG arc pendulum sample platform, manual 360 DEG vertical rotating sample platform, manual 360 degree rotating sample platform, automatic control temperature system (Japan Omron temperature control) and continuous zoom optical system (Nissan), automatic and accurate sampling, automatic image analysis system, the electric three-dimensional platform, custom concave convex special base 2 main functions: Measurement of contact angle (special software to measure the convex concave surface) Measuring surface tension (drop method) Observation and measurement of the drop size (drop method) Calculation of surface free energy (Owens two) 3 measurement method: Instant freeze screenshot Continuous shooting images (1 seconds to 3600 seconds). Automatic high speed camera (12 frames per second) 4 contact angle measuring range: 0~180 degrees 5 image magnification: 55pixel/mm ~ 315pixel/mm Imported continuous zoom optical system: (~1400pixel/mm 100pixel/mm) JC2000Y contact angle measuring instrument 6 measurement accuracy: 0.1 degrees or 0.5 degrees (concave and convex special type)
