Technical questions about measuring static water contact angle? Static contact angle measured the film, because the film always get uneven, resulting in a film, the biggest difference between the measured data can to ten degrees, a sample to be measured for a long time, ask the experts what methods can facilitate the film flatten, or what instruments can be used to prepare a glass slide, put on top of a small nail, with double-sided adhesive film on one side, long 安康迪 CA06 contact angle, paste in a glass slide placed on a nail, Dongguan Condi CA05 drop angle, when the test directly to small liquid drops in projecting position, to facilitate the observation, the contact angle, can also relatively flat membrane stretched firing temperature of the ceramic body to develop a factory waste, re-use expands during firing, it is difficult to determine the firing system. High temperature expansion and contraction of the visual appearance can be visually observed not only in the firing process of the body changes, but also capable of expansion and contraction rate for real-time measurement of body.
