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. After the contact angle of water drops up how long drop to the measurement object reaches standstill take some time, this time is very short, the contact angle meter drop small, basically negligible. If the contact angle measurement dynamic contact angle measurement function, see the contact angle was measured value can be stabilized. Usually within 10 seconds to test the contact angle, Sheng Ding instrument, depending on the contact angle provided by the Dongguan City Ding Sheng Precision Instrument Company. The contact angle, Sheng Ding instrument, depending on the contact angle is Dongguan Sheng Ding Precision Instrument Co., Ltd.
