What is the purpose of the drop angle meter? First of all, let's understand what is the droplet angle. The droplet angle refers to the angle between the gas-liquid interface and the liquid-solid interface at the three-phase junction of gas, liquid and solid when the droplet reaches equilibrium on the surface of the solid, which is called the contact angle. ; Literally it is not difficult to see that the purpose of the water drop angle measuring instrument is to measure the "drop angle".
（(The picture above shows that Shengding Precision adopts the bilateral measurement method of the water drop angle, and the average water drop angle is taken to ensure the accuracy of the data)）
Water drop angle measuring instrument Not only the water drop angle is measured, but also functions such as surface/interfacial tension, surface free energy measurement, rolling angle, advancing and retreating angle can be measured.
