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, γLP polar forces) and measure the liquid contact angle on a solid surface contact angle θ SDC-400 tester, the side through the program can calculate the surface energy of the solid. When calculated using the Owens surface energy SDC-300 contact angle measurement, selected two tests were the following conditions must be met: γLP two liquids / γLD value can not be close to SDC-80 contact angle measurement, and both the gap between the bigger the better; Name: contact angle measurements and applications ?? package contains: glass, LCD, LCM flat panel display, sapphire glass, watches lenses, mobile phones and laptops and shell buttons, CMOS camera and digital camera components, Si , water droplets InP, GaAs wafers, wafer, fiber, circuit board, X-ray lenses, UV / IR lens, the optical disc head components, such as optical elements, the contact angle test.
