1. The use of computer multimedia technology, optics and CCD camera combine to make an image of droplets clearly displayed on a computer screen above the Swiss contact angle of water droplet angle measurement, can store the image at the moment for the measurement of use, avoid liquid evaporation measure failed. 2. The use of the pre-board computer technology Fangrui JCY-3 drop angle, 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 Fangrui JCY angular contact angle of water droplets, can be applied to different materials 5. The instrument can also be calculated using a two-liquid method of solid surface energy surface roughness why the increase The contact angle of water droplets and the contact surface will not necessarily be increased. to look at your material is hydrophilic or hydrophobic. If it is a hydrophilic material contact angle, surface roughness will reduce the water droplets and the contact surface contact angle for hydrophobic materials, due to surface roughness, in fact, increase the contact area of ??water and materials, if the contact angle does not change, the water surface area larger than the original because of the role of surface tension of water is always driven water reduction small surface area, so the contact angle of water droplets will be reduced by increasing the surface area. Fangrui JCY-3 _ Fang Rui drop angle (online consultation) _ contact angle provided by the Dongguan City Ding Sheng Precision Instrument Company. Dongguan Sheng Ding Precision Instrument Co., Ltd. (www.dgshengding.com) (www.dgshengding.com) Dongguan, Guangdong, dedicated instrumentation leaders, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum Limits to meet customer needs. Sheng Ding instrument in leadership with the staff warmly welcome all inquiries negotiations to create Shengding instrument better future.
