Yiwu contact angle measurement instrument | ShengDing Instrument | contact angle measuring instrument wholesale offers from Dongguan City Sheng Ding Precision Instrument Co., Ltd .. Dongguan Sheng Ding Precision Instrument Co., Ltd. (www.gdshengding.com) is a specialist in the "contact angle measurement, tensile tester, drop angle detector, tables, interface equipment," the company. Since its inception, we adhere to the "honesty, sound management" approach, the courage to participate in healthy competition in the market, so that the "" brand has a good reputation. We adhere to the "service first, customers first" principle, so ShengDing instrument has won the trust of customers in the congregation dedicated instrumentation, and establish a good corporate image. Special Note: This information is for reference pictures and information, please contact us to obtain the most accurate information, thank you! Dirty clothes - grease, surface tension of his large, insoluble in water, detergent enable him to reduce the surface tension, which dissolve in water, so the water can wash the dirt from the clothes. Because of surfactants in detergents with. Surfactants reduce the surface tension of water, why do we add detergent in ordinary water can blow bubbles? Because the surface-active agent reduces the surface tension of water, the water is easy to blistering. Detergent molecule is very interesting contact angle measuring instrument retail, one end is hydrophilic group, can be dissolved in water, the other side is a lipophilic group contact angle measurement, can be dissolved in oil. When the laundry, if there is oil, detergent clothes lipophilic group will work with oil "huddled" hydrophilic groups on the outside. Such hydrophilic group and the water is very close, it is easy to lipophilic groups and oil conjugate away. Plus a lot of foam, decontamination ability. Now there are a lot of detergent additives to remove other stains. Surface tension seems to us humans nothing very useful, however, pond insects but they can run around in the water, because water has a surface tension. The famous Tiger Spring Floating coins, but also because a large surface tension. The so-called contact angle measurement touch angle refers drops on a solid horizontal plane of a droplet on a solid surface solid - liquid - gas three-phase bordering point, the gas - liquid interface and solid - liquid interface of two tangents to the liquid phase sandwiched therebetween when the angle formed. The contact angle measuring instrument is mainly used for measuring liquid solid touch angle, ie the wettability of the solid liquid contact angle measurement instrument wholesale, contact angle measurement instrument can measure a variety of liquid on a variety of materials touch angle. Touch angle measurement for oil, printing and dyeing, pharmaceutical, coating, dressing and other professional research and production has a very important effect. Measure the contact angle measurement principle: when a droplet freely in space is not affected by the force field, because of the presence of interfacial tension and cylindrical ball. However, when droplets with a solid planar touch, which ultimately depends on the relative size of the shape of the adhesion of droplets of internal cohesion between the solid and liquid droplets. When a droplet placed on a solid plane, the droplets can automatically start to shop at a solid surface, or solid surface into a touch-angle droplets must exist. Currently Zetasizer more to 500 ~ 700nm wavelength laser as the light source, therefore, the first community-type particle size analyzer for particle size at 5 ?? m above analysis results more accurate, and for particle size less than 5 ?? m particles Milosevic is using a mathematical correction. She therefore the measurement of sub-micron and nanoscale particles have a certain degree of error, even difficult to accurately measure. For the scattering of laser particle size analyzer, the scattered light information directly processing the collected scattered, so she can accurately determine the sub-micron, nanometer-sized particles, while the size of the particles larger than 5 ?? m concerned, scattering Zetasizer you can not come up with accurate measurements. Laser light scattering method to measure particle size distribution 20 ~ 3500nm, access to the equivalent spherical volume distribution, measurement accuracy, speed and high temperature contact angle measuring instrument, representative, reproducible, suitable for measuring the mixed materials. The disadvantage is the requirement for a detector is high, the difference between the respective measurement results of instrumental comparison. Photon correlation spectroscopy method can measure the range of 1 ~ 3000nm particle size distribution, the particle size is particularly suitable for the analysis of ultra-fine nano-materials. Measure the volume of distribution, high accuracy, high speed, wide dynamic range, can study the stability of the dispersion system. The disadvantage is not applicable to the determination of particle size distribution fast sample.
