Droplets angle, ShengDing equipment (certified), drop angles provided by the Dongguan City Sheng Ding Precision Instrument Co., Ltd .. Dongguan Sheng Ding Precision Instrument Co., Ltd. (www.dgshengding.com) is specialized in the "contact angle measurement, tensile tester, drop angle detector, tables, interface instrument" of the enterprise, the company adhering to the "honesty, hard service" philosophy, to provide you with the highest quality products and services. Welcome to inquire! Contact: Lee. And the particle volume (V) relationship can be represented by an expression D = 1.24V1 / 3 Fig. In addition droplets angle, particle size and particle size distribution data for a variety of different analytical methods may not be obtained confirm each other droplets angle measuring instrument, can not be absolutely horizontal comparison. ? Since the particle size of the powder material is widely distributed, from nanometer to millimeter level, so when describing the material particle size, the particles can be divided according to the size of the nano-particles, ultrafine particles, particles, fine, coarse, etc. species. These particles may be based on the type of particle size analysis using the corresponding methods and instruments. In recent years, with the rapid development of nanoscience and technology, particle size distribution and particle size nanomaterials characterization of nanomaterials has become an important indicator of water droplets angle tester, in the ordinary material particle size analysis, particle size of their research in general In the size range of 100nm ~ 1um. Faced with nano-materials research, their greatest concern scales. MN with size proportional to the length of the boundary of the surface tension meter F. Can be written as F = σL or σ = F / L. The ratio σ is called the coefficient of surface tension meter, its unit used dyn / cm. On the numerical coefficient of surface tension meter is equal to the liquid appearance of some adjacent to each other between the two traction unit length. Liquid surface tension meter coefficient = film appearance can / film surface tension meter area = F / (2 * taken segment length). Coefficient of surface tension of the liquid nature of the instrument, regardless of the size of the liquid.
