Uv aging test box plays an important role in the application of mobile phone mirror tube coating. Mobile phone lens tube coating refers to the coating of a special film on the surface of mobile phone camera lens tube, which is used to improve optical performance, enhance wear resistance and scratch resistance. During daily use of a mobile phone, the camera cylinder is exposed to a variety of environments, including ultraviolet radiation, humidity, high temperatures and chemicals. In order to evaluate the durability and stability of the coating, the UV aging test chamber can simulate these environmental conditions, accelerate the aging process of the coating, and perform performance evaluation.

Method of test
The following are the specific steps of UV aging test box in the application of mobile phone mirror tube coating:

Material selection and preparation: Select the coating material of mobile phone mirror barrel that meets the requirements. Commonly used coating materials include silicon nitride (SiNx) film, zirconia (ZrO2) film and so on.

Set test conditions: according to the test requirements, determine the UV radiation source, temperature, humidity and radiation time in the test chamber and other parameters. These conditions should be able to simulate the real UV radiation and mobile phone use environment.

Mounting sample: Fix the sample of the mobile phone mirror barrel on the sample table of the test chamber to ensure that the coated surface is exposed to the UV light source. Surface integrity and consistency of the sample need to be ensured.

Start the test: Start the UV aging chamber and expose the sample to simulated UV radiation. According to the set test conditions, radiation for a certain time. At the same time, humidity and heat circulation can be selectively carried out to simulate the real use environment.

Monitoring and recording: Regularly monitor and record the performance changes of mobile phone mirror barrel samples. The optical properties, wear resistance and surface quality of the coating can be measured and recorded using appropriate instruments, such as surface roughness measuring instrument, film thickness measuring instrument, etc.

Evaluation result: According to the test data and evaluation index, analyze the aging degree and performance change of the coating sample. The difference between different test samples was compared to evaluate the durability and stability of the coating.
