Overview

The water droplet angle measuring instrument adopts the principle of optical imaging, and the equipment uses image contour analysis to measure the surface contact angle, wetting performance, interfacial tension, forward and backward angles, surface energy and other properties of the sample. The equipment adopts a fully automatic liquid inlet device, which has high cost-effectiveness, strong scalability, comprehensive functions, and can meet various conventional measurement needs. Currently, it has been widely used in many universities, colleges and enterprises.

Product Details

Overview

Water droplet angle measuring instrument(Contact angle) refers to the tangent line of the gas-liquid interface made at the intersection of gas, liquid, and solid phases. This tangent line forms an angle θ between the liquid side and the solid-liquid boundary line. Contact angle measurement is currently the main method for surface performance testing.

(Some testing functions require the purchase of specialized accessories to complete)
1. The wetting behavior of liquids on solid surfaces, such as spreading, permeation, and absorption, is measured by the droplet method to determine the static contact angle;
2. Measurement of the advance angle, retreat angle, contact angle hysteresis, rolling angle, and dynamic contact angle of materials on solid surfaces;
3. Continuous real-time research and process recording of absorbing materials, analysis of contact angle variation curve over time;
4. Contact angle measurement of various special materials, such as powders, curved surfaces, superhydrophobic/superhydrophilic samples;
5. Contact angle test of materials immersed in liquid using the attachment drop method;
6. The suspended droplet method is used to measure the interfacial tension, polarity, and dispersion components of various liquids;
7. Calculate the surface free energy of solids and analyze their polar dispersion components;
8. Analyze the adhesion energy of liquids on solid surfaces, evaluate the uniformity and cleanliness of solid surfaces, etc.
