The water droplet angle measuring instrument is a good indicator for measuring surface wettability

The droplet angle tester can use the syringe needle attached to the product to drop a droplet of the liquid to be tested onto the substrate. The droplet will adhere to the surface of the substrate and cast a shadow. The projection screen will use optical magnification to project the image onto the screen for measurement. The contact angle is the contact angle between the liquid/solid/air interface and the solid surface. When a droplet is placed on a smooth and uniform horizontal surface, it may diffuse onto the substrate, and if complete wetting occurs, the contact angle will approach zero. On the contrary, if the wetting is partial, the obtained contact angle reaches equilibrium within the range of material surface energy, and the smaller the contact angle, the greater the wettability or surface energy of the substrate. There are several types of water droplet angle measuring instruments from Zhenyi Corporation, including split action water droplet angle measuring instruments, semi-automatic water droplet angle measuring instruments, and fully automatic water droplet angle measuring instruments. The characteristics and prices of the three types of contact angle measuring instruments are different. Next, the editor will provide a detailed introduction to the steps and precautions of using water droplet angle contact angle measuring instruments, as well as the areas that can be tested;

1、 As is well known, the water droplet angle measuring instrument usually includes the following steps during operation:

1. Adjust the lens and light source, calibrate the data;

2. Place the product on the testing platform, adjust the lifting platform to place the product within the lens testing range;

3. Rotate the plunger of the syringe and drip according to the standard volume;

4. Rotating droplet lifting platform to drop water droplets onto the surface of the product;

5. Click on the angle measurement function on the software on the computer to obtain contact angle data.

2、 The details that are often overlooked when using a water droplet angle contact angle measuring instrument, the editor will explain some precautions for lightning protection:

1. Gloves should be worn during the operation to avoid hand contamination of the sample or affecting the test results;

2. The samples should be placed horizontally to ensure the accuracy of the test results;

3. Take the average of multiple measurements to improve the reliability of the test results;

4. After use, the light source should be turned off promptly to protect the instrument and extend its service life.

3、 Contact angle measuring instruments can meet any of the following measurement and testing requirements:

1. How effective is the detection of surface wettability and adsorption force;

2. What are the surface tension values and surface properties to be tested;

In summary, the waterdrop angle contact angle measuring instrument is a high-precision, multifunctional, and easy to operate measuring instrument. Dain Technology provides a complete set of Dain test liquids to measure surface energy, and the use of Dain value test liquids can quickly and easily display surface wettability. The waterdrop angle measuring instrument is mainly used to measure the contact angle, surface free energy, wettability and other parameters of solid surfaces. Currently, it can be widely used in semiconductor manufacturing, electronics industry, biomedical, new energy, silicone rubber and other fields to evaluate the cleanliness, adhesion, hydrophobicity and other properties of material surfaces.
