Three main applications: Wettability of metals, ceramics and other composite materials; Wettability 2. The high temperature materials; 3. dynamic process under high temperature and high vacuum material; 4. Surface tension refractory material ; 5. high temperature welding on vacuum brazing. The contact angle measurements: Owens two-liquid method to calculate the solid surface energy (solid surface tension) The instrument also provides a two-Owens calculated the surface energy of the function, as follows: using known liquid surface energy γL and its sub-γLD , γLP, (γLD as dispersion forces, the contact angle method, γLP polar forces) and measure the liquid contact angle θ on a solid surface, the contact angle, the side through the program can calculate the surface energy of the solid. When calculated using the Owens surface energy, selected two test solution must meet the following conditions: γLP / γLD values ??of the two liquids can not close, and the gap between the bigger the better; the contact angle of water droplet angle, Sheng Ding instrument ( certification), the contact angle provided by the Dongguan City Ding Sheng Precision Instrument Co., 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.
