Use some of the polar solvent, a polar solvent is used sequentially: the contact angle of water (max)> formamide> acetonitrile> methanol> ethanol> propanol> acetone> dioxane> tetrahydrofuran> methyl ethyl ketone> butanol> Ethyl acetate> ether> isopropyl ether> dichloromethane> chloroform> dibromoethane> benzene> CTC> Carbon disulfide> cyclohexane> hexane> kerosene (minimum). You can try this order. Then you Try cyclohexanone it, contact angle, his volatility is still relatively small. 1. The use of computer multimedia technology, Shanghai surplus Connaught contact angle optical system and CCD camera combine to make an image of droplets clearly displayed on a computer screen on, you can store the image at the moment for the measurement used DKSH contact angle, to avoid liquid evaporation measurement fails. 2. The use of pre-SBC technology, Rame Hart contact angle, temperature, angle of rotation of the platform real-time sampling, the operator focus, move horizontally, vertically moving 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 hundred Olin Swedish law can contact angle | Shengding instrument (Online Consulting) | contact angles 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.
