Application of high and low temperature test Chamber around mobile phone

 

 

Digital electronic products such as mobile phones, cameras, and other general manufacturers purchase high and low temperature test chamber environmental test equipment to perform high and low temperature tests on the products, such as testing mobile phone batteries. Will the high temperature explosion occur at ﹢ 100 ℃? The high and low temperature test box brings us safety guarantees, so that what consumers buy can be safely used in different environments, so the high and low temperature test box is inseparable in our daily life, no matter in life The equipment is still in production.
 
So as a mobile phone film as one of the essential accessories to protect the phone, how about the temperature tolerance? Let's take a look at it, or pull out our tall Shanghai Da high and low temperature test box and set the temperature to the high temperature conditions that we may encounter in the natural environment.
 
1.Understanding the test object

2. High temperature test
Since the content of the test is to detect the high temperature resistance of the phone's tempered film, the daily temperature does not have any substantial meaning. Even the highest temperature in summer will not have a great impact on the phone's tempered film. Today I will directly simulate the high temperature conditions that mobile phones may encounter in summer. First, start with a high temperature of 70 ° C and observe whether the tempered film has changed.
70 ℃ high temperature test
Step 1: First of all, please get out our high and low temperature test box and put the test samples in the box.

Step 2: Start the high and low temperature test box on the high and low temperature, set the temperature to 70 ° C, and run for 1 hour (note that the temperature is 70 ° C for 1 hour).
Step 3: Observe the test sample after the time, and observe its shape, viscosity, foaming, etc.

3. Extreme temperature test
This tempered film is still intact at the high temperature of 70 ° C, so the test was performed at a temperature of 80-90-100 ° C. Of course, there is no change. No matter whether it is viscosity or shape, it is directly extreme. Make it 150 ° C a bit, then someone will ask, under what conditions will the mobile phone encounter a high temperature of 150 ° C? In fact, it can be concluded now that the shape of the tempered film will not be affected by the high temperature. What is to be measured now is whether the extreme temperature can melt this hardened tempered film.
150 ℃ high temperature test
Step 1: Put the tempered film on the high and low temperature test box sample rack.
 
Step 2: Start the high and low temperature test box on Tall University again, set the temperature to 150 ° C, and run for 1 hour (note that the temperature is constant for 1 hour at 150 ° C).
 
Step 3: Observe the test sample after the time, and observe its shape, viscosity, foaming and other aspects. After taking out the tempered film from the high and low temperature test box on the high and high temperature, it was left for about ten minutes in the external environment before gradually lowering the temperature. Surprisingly, there was no other change except the heating tempered film, that is, even in a high temperature 150 ° C environment , Still intact as before, no bubbles, no deformation, and can be used, this quality and Haida's test box has a fight ~
4 low temperature test
After testing the high temperature resistance of the tempered film, it is time to test the low temperature conditions. The editor knows what the minus and twenty degrees have little effect on the tempered film. Let ’s make a lower temperature. Whether the tempered film will be affected.
-45 ℃ low temperature test
Step 1: Put the tempered film on the high and low temperature test box sample rack.
 
Step 2: Start the high and low temperature test box on Tall University again, set the temperature to -45 ° C, and run for 1 hour (note that the temperature is -45 ° C for 1 hour).
 
Step 3: Observe the test sample after the time, and observe its shape, viscosity, foaming and other aspects. It can be seen that a thin crystal has formed at the moment the door is opened due to the low temperature, but! Our tempered film is still intact, without being affected by temperature.
 
V. Test Summary
 
After a day-long repeated temperature test, the tempered film of this iPhone XS is still unaffected, and the questions in the title have been answered. Yes, the tempered film iPhone XS is really safe! Xiaobian is very pleased, I treasured this excellent quality tempered film, and now I have an iPhone XS ~
