Contact angle measurement instrument where good _ _ ShengDing 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! 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, usually completed using a contact angle measuring instrument interface directly antennae accurate measurements. A brief description of the commonly used measurement methods and related operating requirements below. To pay attention to the degree of understanding of user needs with features for testing surface tension, surface tension test method JC2000 series that came to the hanging drop method, classic, accurate, high requirements for operators (influenced by the operating level). If it is different testers need to batch test table interfacial tension, it is recommended to use my company's JK99 series of automatic tension meter, when droplets freely in space is not affected by the force field, due to the presence of the interfacial tension and cylindrical ball. However, when the droplet with a solid surface contact, depending on the final shape of the droplet and the relative size of the internal cohesion of the adhesive force between the droplet and the solid. When a droplet placed on a solid plane, the droplets can automatically start to shop at a solid surface, or in contact with a solid surface into a certain angle of droplets exist. Electrophoresis (electrophoresis) in the electric field force, directed migration of charged particles in the suspension system, the particle size and particle size mobility related to its mobility by measuring the particle size can be calculated. Electrophoresis can be measured is less than a particle size of 1 ?? m intravenous contact angle meter, but only to obtain an average particle size of the contact angle meter outlets, it is difficult to measure the particle size distribution. Fisher method (fisher? Method) Fisher method first law of the land belonging to the steady flow of gas (laminar) state. Under constant pressure, measured particles through the air first? Accumulation body, then flows through an adjustable needle valve atmosphere. According to the air flow resistance and stole particles generated when stacked body surface area can be obtained and the average size of the particles. Fibonacci method is a relative measurement method, size book is called Fei average size of brand contact angle measuring instrument, can not accurately reflect the true size of the particles, we can not, and other particle sizing methods to compare the results can not be accurately reflect the true size of the particles, and the results can not be obtained by other particle sizing methods were compared, only used to control the process and product quality. Typical products are the United States, Fisher Number sieve grade powder tester.
