Contact Angle Test Instrument For Silicone Rubber IEC TS 62073 methods A.

Test methods: static drop method, drop method, drop method, tilt plate method.


1.Static drop method.

Drop a drop of liquid on the solid surface, take a picture of the equilibrium system after the solid-liquid-gas three-phase interface is balanced, and measure the antenna through the contact Angle measurement method provided by the software.It is also possible to take timed photos or video of the balancing process during the test, and then analyze the change process of the system.


2.Drop method.

Due to the non-uniformity of the solid surface, it is sometimes necessary to measure the dynamic contact Angle to analyze the hysteresis of the contact Angle. This instrument can measure the forward Angle by continuously increasing the liquid drop amount or measuring the backward Angle by continuously decreasing the liquid drop amount.


3.Turn left method

The Angle rotation (electric) of the platform is controlled by computer to measure the droplet rolling Angle.


4.Inclined plate method

This method can also be used to measure the forward Angle and backward Angle of the contact Angle. The main idea is to drop liquid on the solid surface, and then tilt the solid surface at a certain Angle, so that the forward Angle and the backward Angle of the larger end of the liquid drop can be measured.
