Problems solved by technology
[0009] The first test device for anti-fog performance is too simple, and the test results are biased and not quantified. The test results are observed by naked eyes, which are completely based on personal experience. The test results vary from person to person, and the deviation is large
[0010] The second type of anti-fog performance test device involves professional angle measuring equipment, and the results of the test method are relatively quantitative, but the shape of a single droplet is considered, and it is impossible to obtain the line of sight such as light signal intensity or light transmittance. Relevant indicators that have a direct impact
[0011] To sum up, there are certain defects and deficiencies in the current existing testing devices and testing methods, and it is impossible to obtain the best testing effect, and further improvement is still needed.

A device for testing the anti-fog performance of glass coatings, characterized in that: it includes a signal emitting component, a light source capable of emitting parallel light; a light baffle plate with a light outlet; a signal receiving component, equipped with a detection device that can collect light intensity Probe; clamping part, located between the light baffle and the detection probe, the clamping part is used to fix the glass test block to be tested; detection circuit, used to record the light intensity signal collected by the detection probe and each A collection time corresponding to the light intensity signal. The advantages of the present invention are: 1. The overall structure is compact, simple and convenient to install, and easy to operate; 2. The addition of a photoelectric detection system can directly detect the light intensity value transmitted by the glass test block, and then determine the anti-fog performance of the glass coating. The accuracy is higher than that observed by naked eyes, and the result stability and precision are high.
Description
technical field [0001] The invention relates to a device for testing the anti-fog performance of glass coating. Background technique [0002] Transparent optical materials (such as silicate glass, quartz glass, polyethylene, etc.) are indispensable materials in modern people's production, life and work. In the past few decades, people have been committed to solving the problem of surface atomization of transparent optical materials . [0003] When the surface of a transparent optical material is fogged, many small water droplets of different sizes will be formed, and the directions of reflection and scattering of light by different water droplets are also different, thereby reducing the light transmittance of the transparent material and affecting people's ability to pass through the optics. Observing the effect of other objects on the surface of the material will destroy the accuracy of the results of scientific experiments. For example, in solar cells, the energy utilizat...
