Meaning of measurement
The gloss measurement of mobile phone film is to evaluate the optical performance of the film, which includes parameters such as transparency, reflectivity and refractive index. These parameters have an important impact on the protective function of the film and the user experience.
Clarity of the film: Transparency refers to how much light the film transmits. The high-transparency film can make the screen display clearer and brighter, and reduce the visual distortion caused by the film.
Reflectivity of the film: The reflectivity refers to how much light the film can reflect. Films with high reflectivity will produce reflections under sunlight or strong light, which will affect the user experience and may even cause damage to the eyes.
Refractive index of the film: The refractive index refers to how much light can be bent by the film. An index of refraction that is too high or too low can cause problems such as blurring and distortion of the screen.
The gloss meter can be used to detect the surface gloss of the film in the gloss test of the mobile phone film to evaluate the quality of the film.
Measurement steps
Preparation: Paste the film to be tested on a clean surface to ensure that the surface is clean and free of impurities, so as not to affect the test results;
Adjustment instrument: adjust according to the instruction manual of the gloss meter to ensure that the instrument meets the test requirements. Generally, zero point calibration and reference plate calibration are required;
Measurement: Place the test head of the gloss meter on the surface of the film, and start the instrument for measurement. Generally, multiple tests are required to take the average value to avoid errors;
Document the results: The measurement results are documented, evaluated and classified according to relevant standards. At the same time, the test results can also be compared with other films to facilitate the selection of better quality films.
Beichao reminds you: when measuring the glossiness of mobile phone film, it is necessary to consider that the material and color of the film may have a certain impact on the test results. For example, there may be differences in the film material produced by different manufacturers, resulting in differences in gloss. At the same time, there may be differences in the surface gloss of different colors of film. During the measurement process, it is also necessary to pay attention to the stability of the test environment to avoid the influence of factors such as temperature and humidity. It is necessary to conduct a risk assessment of the film before measurement, and pay attention to the protection of the film during the measurement process to avoid damage to the film
