The auto industry, which has a high search rate recently, is doing its part. . . First, the engine oil spill incident of a certain Chi, then the formaldehyde exceeding standard incident of a certain Di, and then the paint peeling incident of a certain Jie.
Today, Xiaobian and you decode a laboratory box that is most used in our automobile industry - xenon lamp weather resistance test box
Xenon lamp weather resistance test is an important means of screening formulas to optimize product composition in the process of scientific research and production, and is also an important content of product quality inspection Applied materials such as coatings, plastics, aluminum-plastic panels, and automotive safety glass require weather resistance test.
Features of xenon lamp weather resistance Test Chamber:
1. The xenon lamp aging test has the function of rain and spray;
2. The xenon lamp aging test can well simulate the changes of materials exposed to sunlight under different environmental conditions.
What is the difference between the UV weather resistance test box and the xenon weather resistance test box?
There are mainly three types of test equipment for artificial weathering: xenon lamps, ultraviolet fluorescent lamps, and carbon arc lamps. The xenon lamp can also easily simulate the repeated alternating test conditions of daylight, night condensation or rainfall, among which the xenon lamp is better at simulating the solar spectrum, while the fluorescent lamp climate aging is a device that simulates the ultraviolet spectrum of sunlight closer, and the accelerated aging effect is more significant . The test method of carbon arc lamp will be phased out gradually. The xenon lamp aging test is a comprehensive climate test device. In addition to the weather aging test, it can also test the light resistance of high-resolution materials, that is, the polymer material is exposed to artificial light sources that simulate the sunlight spectrum through the glass to evaluate the light resistance of the material. performance.
What are the water quality requirements of xenon lamp weather resistance Test Chamber?
The xenon lamp weather resistance Test Chamber has humidity and spray requirements, so the water consumption of the Test Chamber is relatively large, so this has requirements for the water quality. If the water is not used correctly, the impact and damage to the equipment will be quite large. , So there is why the xenon lamp weather Test Chamber must use pure water in the industry? The following editor will explain to users from three aspects, hoping to help everyone.
1. The humidifier has a water level switch, and the middle of the floating ball of the water level switch is a magnetic rod, because the floating ball is not made of imitation oxidation material, so after a long time, or if the water is not changed frequently, the water level switch will be short-circuited, resulting in failure to humidify And the phenomenon of constant humidification;
2. Because the water humidification particles are relatively large, there is a requirement for humidity for a long time, which will affect the service life of the humidity sensor. However, some circuits on their PCB boards are not made of water-proof materials or anti-oxidation materials. If the water quality Poor, it will short out the humidity sensor.
3. The spray aperture is small, and impurities in the water will cause nozzle blockage.
How to control the irradiance of the xenon lamp climate Test Chamber?
Theoretically, light intensity can be monitored anywhere in the xenon lamp spectrum, but only a few bands are used. Irradiance control is generally performed in the spectral region where the material is most sensitive (eg, where degradation is expected to occur). In addition, the irradiance control point also changes due to different industries and applications.
