What is a fully automatic water droplet angle tester, which measures the contact angle of water droplets on the surface and basically evaluates the degree of water "wetting" the surface, while a "dynamic friction coefficient tester" measures the frictional force between two moving surfaces, indicating the sliding resistance between them;

In short, the waterdrop angle tester analyzes the wettability of surfaces, while the dynamic friction coefficient tester measures the sliding friction between surfaces.

As is well known, nanomaterials science and engineering have become a hot research topic worldwide. When studying surface modification of nanomaterials, wet contact angle is usually involved. Contact angle refers to the angle surface between the solid liquid gas three-phase interface, gas liquid interface, and solid-liquid interface on the solid surface,

 used to measure the degree of chemical bond breakage between molecules on the material surface. In solid-state physics theory, surface atoms have more energy than atoms in materials. Therefore, according to the principle of minimum energy, atoms spontaneously tend towards the interior rather than the surface.

The application fields of precision instruments such as water droplet angle include: pre coating quality of printed circuits, etc; Plastic industry, surface cleaning and bonding quality measurement, measurement of surface wettability and compatibility, measurement of wafer cleanliness, research on photoresist and imaging agents, research on waterproof and hydrophilic materials; Surface activity and surface tension and humidity of detergents; Epoxy adhesion measurement, surface activity and detergent tension and humidity, measurable adhesion.

The construction and operation process of water droplet angle: Precision measuring instruments generally use modern manufacturing technology, which adopts advanced dedicated CCD digital cameras, high-resolution zoom microscopes, multi background and high brightness LED light source systems. With the 3D sample holder, the workbench can move up and down, left and right, and forward and backward, achieving precise movement of micro area sampling, up and down, and left and right. We also designed a telescopic pole structure workbench that can adapt to situations where the thickness of materials increases for different users.

In addition, the size of the instrument framework can be adjusted, the instrument range can be expanded, the software has calibration function, and the test results can be saved multiple times with the same report, allowing users to better control material data. The instrument design is aesthetically pleasing, easy to operate, and meets user needs

Optical contact angle measuring instrument: It is a simple, fast, and sensitive method for measuring the wettability of solid surfaces, which can indirectly measure the surface tension of solid surfaces. The following is a comparison table of testing methods, and the product advantages are as follows:

1. High precision automatic spraying system, with a minimum droplet control accuracy of 0.1 microliters;

2. Adjustable LED industrial grade cold light source system (up to 20000H), providing clearer imaging and avoiding evaporation of small water droplets caused by overheating;
