1. The use of computer multimedia technology, optics and CCD camera combined Fangrui contact angle of water droplet angle measurement, so that the image of droplets clearly displayed on the computer screen, you can store images in an instant for the measurement of the next use to avoid evaporation of liquid resulting in measurement failure. 2. The use of pre-SBC technology, temperature, angle of rotation of the platform real-time sampling, the operator focus, horizontal movement, vertical movement motor control platform for thermostatic control. Good 3. An external water bath, temperature performance 4. Adopt special fixture and platform, applicable to different materials 5. The instrument can also calculate the solid surface with a two-liquid method can droplets height / width method using equations to fit round summarize shape of the droplet, which accounted for the contact angle. Since this approach assumes that the droplets (cross-section) is part of a circle shape Fangrui JCY angular contact angle of water droplets, so its scope is limited to spherical or near to spherical droplets. Due to the influence of gravity, strictly speaking Shanghai Fang Rui instrument tester, are contrary to the shape of the droplet ball: The degree of the breach increases with increasing droplet volume; at the same volume, the greater the proportion of the liquid, The smaller the surface tension, the greater the violation of ups and downs. Under normal circumstances, on volume of less than 5 microliters of water droplets, which suffered the impact of gravity on the shape is considered small enough to be negligible, this approach accounts available at the moment. Speaking after the literature measuring the height and width of the droplet contact angle of approach to accounting that is the round could have been the easiest method to use. The above mentioned method Conic round Act would have been included, because the circle of a quadratic equation only exception. Fangrui contact angle of water droplet angle measurement _ _ Fangrui contact angle provided by the Dongguan City Ding Sheng Precision Instrument Company.
