What is the xenon lamp weather test chamber

The xenon weather resistance test box is also known as the "xenon lamp aging test box". According to the test standards and methods, it is divided into three types: air-cooled xenon lamp, water-cooled xenon lamp, and desktop xenon lamp. The difference lies in the temperature, humidity, accuracy, and time of the test. It is an indispensable testing instrument in the aging test box series.

 

The xenon lamp weather resistance test box uses a xenon arc lamp that can simulate the full sunlight spectrum to reproduce the destructive light waves existing in different environments, and can provide corresponding environmental simulation and accelerated tests for scientific research, product development and quality control.

 

The xenon lamp test box can be used to select new materials, improve existing materials, or evaluate changes in durability after changes in material composition. It can well simulate the changes in materials exposed to sunlight under different environmental conditions.

 

The xenon lamp weather resistance test box has humidity and spray requirements, so the water consumption of the test box is large, then this has requirements for the water quality, if the water is used incorrectly, the impact and damage to the equipment will be quite large , So there is why pure water is required for the xenon lamp weather test box in the industry? The following xenon lamp weather test box manufacturers explain for users from two aspects, hoping to help everyone.

 

1. The humidifier has a water level switch. The middle of the float of the water level switch is a magnetic rod. Because the float is not made of oxidized material, it will cause the water level switch to short-circuit after a long time, or if the water is not changed frequently, which will cause the water level switch to be unable to humidify and keep it constant. The phenomenon of humidification.

 

2. Because the water humidification particles are relatively large, the humidity is required for a long time, which will affect the service life of the humidity sensor, but some of their PCB boards are not made of water-proof or anti-oxidation materials. If the water quality is If it is poor, it will short-circuit the humidity sensor.

 

3. The spray aperture is small, and impurities in the water will cause the nozzle to block.

 

The main factors that cause material aging are sunlight and humidity. The xenon lamp climate test chamber can simulate the hazards caused by sunlight, rain and dew. The xenon lamp is used to simulate the effect of sunlight, and the condensation humidity is used to simulate rain and dew. The tested material is placed in a certain The test is carried out in a cycle program of alternating light and moisture at temperature, and the hazards that occur outdoors for months or even years can be reproduced in a few days or weeks. The artificial accelerated aging test data can help select new materials and transform existing ones. Materials and how to evaluate how changes in formula affect the durability of the product.
