Sheng Ding instrument (Figure), the contact angle measuring instrument wholesale, Enping contact angle measurement provided by the 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 congregation in chemical 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! The so-called contact angle is dropping a droplet on a solid horizontal plane, solid appearance on solid - liquid - gas three-phase bordering point, the gas - liquid interface and solid - liquid interface of two tangents when the liquid sandwiched therebetween the angle formed. Contact angle measuring instrument used to measure the primary liquid contact angle on a solid, namely liquid wettability of the solid, the instrument can measure a variety of liquid contact angle on a variety of materials. The instrument for petroleum, printing and dyeing, pharmaceutical, coating, dressing and other professional research and production has a very important role. When the droplets in the free space is not affected by the force field, the presence of the interfacial tension and the cylindrical ball. However, when the droplet with a solid surface contact, which depends on the shape of the droplets, after all, the internal cohesion and adhesion to the relative size of droplets between the solids. When a droplet placed on a solid plane, the droplets can automatically start to shop in a solid appearance, or the appearance of a solid contact angle of droplets must exist. Measures related to measuring the contact angle in front of the analyzer were introduced, should pay attention to the following two questions about the implementation: Balancing time and system temperature stability, when the system is not balanced, the contact angle will change, when the contact angle of said Dynamic contact angle, dynamic contact angle of a liquid on a number of large research activity on the viscosity of the solid planar or spreading is important (because the viscosity is large, the time length of the balance). Together with the contact angle measurement instrument suppliers, temperature changes on a larger contact angle measurement system works, because of changes in surface tension, contact angle will change, and thus the contact angle measurement, if one has Kipping up balanced system, contact change in angle can be related to changes in temperature, determining the impact factor approach schematically a contact angle measurement instrument manufacturers, affect the balance of the time is usually in one direction, while the temperature fluctuations can be formed in the raised or lowered γ. In addition to balancing time and temperature, the effects of exposure to the elements as well as the angle stable contact angle hysteresis and adsorption. When the contact angle measurements, the droplet size and the contact angle is no linear relationship between the amount of sample 0.6 ~ 1.0ul are the best, the droplets are too small by Volatile is too large, the droplet is too large gravity factor significantly. Note that the test should not be free-falling droplets dripping on the solid surface and the sample platform should rise, touch suspended in the lower end of the injector after the droplets fall, the droplets remain on the solid surface. Of course, if the choice of fully automatic operation of the model above problem does not exist.
