The above mentioned Conic law had also been included circular method, because the circle of a quadratic equation is just a special case. When the volume of the droplet is large, or a large proportion of liquids or surface tension of the liquid is relatively small, the formation of a significant breach of its spherical shape, can now use this approach could result in a large measuring errors can be as large as tens of degrees. So be sure to pay attention to the limitations of this approach. Advocates of this approach is only used in calculating the droplet droplet contact angle of less than 30 degrees, or the shape of equal or close to the ball. C2000 series has a contact angle measuring instrument instantly freeze, automatic continuous photography, high speed photography three kinds of shots the way the contact angle quote, even volatile liquid can also ensure accurate measurement. Meanwhile, outside the influence of subjective factors tangent is the biggest problem, JC2000 series of contact angle measurement of the geometric operations being done in software direct contact angle, the contact angle is no longer human judgment. Measurement of small axial compressive bending bending properties of single fibers is indeed a major breakthrough in the field of fiber detection. One end of the grip is measured using an open end of the hinge analog measurement method is simple to make sample loading control. Fiber pair, fiber protruding length, fiber diameter compression bending process are used in combination in situ measurements of optical contact angle, making it the result of discrete small, reproducible. The fiber fineness and rigid flexible, selective measurement proper aspect ratio of a single fiber sample, its results are accurate and reliable. Because the presence of non-uniformity of solid appearance, and sometimes needs to measure the dynamic contact angle, in order to analyze the contact angle hysteresis, the instrument can measure the amount of liquid droplets through a series of added travel angle or successive cuts amount to measure droplet receding angle. Wholesale contact angle, the contact angle of Zhuhai City, ShengDing instrument (View) provided by the Dongguan City Sheng Ding Precision Instrument Co., Ltd ..
