As we all know, when studying the surface modification of materials, the term wetting contact angle will be involved. The so-called contact angle refers to the gas-liquid interface and The angle between the liquid-solid interface, the device to measure the contact angle is called a contact angle meter.

However, there are many types of contact angle measuring instruments. They were first introduced from abroad. After continuous research and development, domestic contact angle measuring instruments have caught up with foreign countries and achieved surpassing. So where is the advanced nature of domestic contact angle measuring instruments? ? Below, Shengding Precision will reveal it for you!

1. Video acquisition system that should be used in domestic contact angle measuring instruments：

At present, Sindin Precision adopts a dense array of LED cold light sources, with uniform brightness and avoiding the volatilization of small droplets caused by extra heat, which can also reduce the impact of the light source on imaging, and achieve high-precision edge contour analysis. Sindin Precision The parallel light source technology is specially designed for contour testing like surface/interfacial tension and contact angle measurement, with high precision and zero imaging error.

2. Lenses used in domestic contact angle measuring instruments：

Sindin Precision adopts the high-fidelity telecentric zoom lens with international leading design standards, no deformity, no distortion, 0.7-4.5 times continuous zoom function, which is easy to adjust and use while showing the real liquid form; at the same time, it adopts imported industrial The video speed of the sony chip is not less than 50 frames, and the global shutter can perform dynamic measurement with one button. The nano image source has better light sensitivity and sharper imaging.

3. The domestic contact angle measuring instrument adopts high-precision mechanical structure design：

Sindin Precision adopts high-strength aviation aluminum alloy, high-precision adjustable foot cup, stable and reliable, modular design concept, strong equipment scalability; also designed a large-scale contact angle measurement with a maximum measurement of 21 inches for large-size, non-cuttable samples The instrument can be rotated 360° to easily measure various positions of the sample; in order to cooperate with automated streamline operations, Shengding Precision has designed the first domestic non-contact intelligent online automatic detection, which can customize the product size detection position and The number of detections greatly improves the detection efficiency and breaks the limitations of the traditional contact angle, which is also a highlight and breakthrough point of the domestic contact angle measuring instrument.

4. Domestic contact angle measuring instrument analysis software：

We all know that the core part of the contact angle measuring instrument is its analysis software. Sindin precision contact angle measuring instrument software and integrated chip circuit control are independently developed and designed, and have a number of national invention patent certificates; The comprehensive, complete and accurate fitting method is suitable for the measurement and analysis of the contact angle of any material surface. The following pictures are shown for you;

In summary, we can easily see the advanced nature of Sindin precision domestic contact angle measuring instruments, such as advanced design and development concepts, aviation-grade materials, and independent research and development of integrated chip circuit control. With 8 major analysis functions, it is unique in the functions of "online contact angle analysis" and "spread size analysis", with complete fitting methods and high-precision measurement data.

It is believed that in the future, there will be more advanced breakthroughs in domestic contact angle measuring instruments, and Sindin Precision will continue to realize domestic substitution! (www.ledcnhyh.com)
