On the solid surface of the solid - liquid - gas at the point of the three-phase bordered by gas - liquid interface and the solid - liquid interface between two tangents to the liquid interposed therebetween is formed when the angle is called contact angle. In the industrial production process powder contact angle measurement, usually using a contact angle measurement is completed accurately measure interface directly antennae. A brief description of the commonly used measurement methods and related operating requirements below. JC2000X series refers to the large platform (such as 52-inch LCD screen can not be cut test, you need 1200 × 900mm platform) contact angle measurement instrument price, need special dedicated test platform and structure, is generally understanding of customer needs customized 2: a, platform size; b, platforms need to test points. (Requires test platform section points or edges than required test platform for all points cheaper), for example AU Optronics, Rainbow shares. The contact angle measuring instrument for measuring the contact angle of a liquid on a solid, namely liquid wettability of solid contact angle measuring instrument can measure a variety of liquid contact angle on a variety of materials. Contact angle measurement instrument for petroleum, printing and dyeing, pharmaceutical, coating, mineral processing and other industries research and production has a very important role. Light Scattering Method light scattering method (light scattering) is divided into static and dynamic and static light scattering (ie, time-averaged scattering) measurement of the scattered light distribution space, dynamic light scattering study law scattered light at a fixed spatial position in The variation of the intensity with time. Mature light scattering theory mainly Fraunhofer (Fraunhofer) diffraction theory, Fresnel (Fresnel) diffraction theory, M. (Mie) and Rayleigh scattering theory (Royleigh) scattering theory. Laser particle size analysis is the most major nanomaterials system size analysis methods. When a beam wavelength granularity on certain small spherical particles, the diffraction and scattering two phenomena occur for λ laser irradiation, when the particle size is usually larger than 10λ time to diffraction phenomena based; when the main diffraction phenomenon; when When the particle size is less than 10λ, places scattering based. Generally direct contact angle measurement, analysis of samples laser diffraction particle size analyzer only at 5 ?? m more accurately; and dynamic light scattering particle size analyzer is of nanometer size in 5 ?? m or less, submicron particles Sample Analysis accurate. In addition, the theoretical model of laser particle size analysis is based on the particle shape for the autumn, on a single dispersion conditions, but actually measured particles are mostly irregular shape and showed polydispersity. Therefore, the shape of particles, particle size distribution characteristics of the final result of the larger particle size analysis, and the irregular particle shape and particle size distribution is wide, the greater the results of error analysis.
