The so-called contact angle refers to drop a droplet on a solid horizontal plane, solid appearance on solid - liquid - gas three-phase border point, the gas - liquid interface and solid - liquid interface of two tangents when the liquid sandwiched therebetween the angle formed. The contact angle measuring instrument angular contact angle of water droplets maintenance, mainly used for measuring the contact angle of a liquid droplet on a solid angle measurement angle measurements of water droplets, ie liquid to solid wettability, the instrument can measure a variety of liquid contact angle on a variety of materials . The instrument for oil, printing and dyeing, pharmaceutical, coating, dressing and other professional research and production has a very important role. When the droplets in the space free from influence of the force field, due to the presence of the interfacial tension and cylindrical spherical. However, when droplets with a solid planar contact, which depends on the shape of the droplet after all internal cohesion and adhesion to the relative magnitude between the droplets and solid. When a droplet placed on a solid flat angle of water droplets, the droplets can automatically look at the solid start to shop, or to the appearance of a solid contact angle of a droplet must exist. Platinum plate method: When immersed in the liquid under test is sensed, the surrounding platinum plate would be the effect of surface tension of the liquid surface tension will try to pull down the platinum plate. When the liquid surface tension force and other related counterbalance equilibrium angle of water droplets manufacturers, sensing a platinum plate will stop inside the liquid immersion. At this time, the instrument will measure the balance sensor immersion depth, and converts it to the surface tension of the liquid. Platinum loop method: As is widely used du Nouy Tensiometer, this method is also known du Nouy method, and consequent easy operation is widely used. Platinum Tour de France said the law is the result of this test section between the liquid sample obtained will form a ring. JK99 Series Automatic tension meter for measuring regular table / interfacial tension, because its simple (one-button automatic), high speed (3 seconds), good repeatability and high measurement accuracy, is currently the most widely used tension meter. The disadvantage is that not measure ultra-low interfacial tension (such as oil and crude oil interfacial tension between the drive should be 10-5mN / m, can not be measured with a series JK99). JK99 Series Automatic tension meter imported sensors, although the cost is much higher than the domestic torsion wire sensors, but to ensure that the measurement accuracy. While using a dual temperature control technology, built-in electric heating or external temperature bath temperature control options. JK99B type must be connected to a computer to use, JK99C type as one of the dual-use, built-in LCD digital display and a small printer that can single stand-alone operation, but also can be connected to a computer to control the dynamic changes observed tension curve. Other parameters such as exactly the same two models of precision. Recruitment agents _ Heshan droplets drops corner angle _ ShengDing provided by Dongguan Sheng Ding Precision Instrument Company.
