Matters needing attention in the use of water-cooled xenon lamp aging tester

 

The water-cooled xenon lamp aging tester is mainly used for aging tests of various plastic products, rubber, paint, automotive interior parts, coatings and other products. According to the position, it can be divided into blast type and flat type, and according to power, it can be divided into water-cooled type and air-cooled type. The weather resistance of sunlight is mainly accomplished by artificially simulating sunlight.

 

There are two commonly used xenon lamp aging testers, one is the air-cooled xenon lamp aging test chamber, its structure is to irradiate from the top to the bottom, and the sample is placed on the slope below, and the other is the drum type structure, the xenon lamp tube is located In the middle of the drum, the sample is placed on the drum wheel.

Comparison of test data of water-cooled xenon lamp aging tester with natural aging data:

 

Damage to materials by natural sunlight and moisture will cause inestimable economic losses every year. The damage caused mainly includes fading, yellowing, discoloration, strength reduction, embrittlement, oxidation, brightness reduction, cracking, blurring, powdering, etc. For products and materials directly exposed to sunlight or through glass windows, the risk of being affected by light damage is high. Substances exposed to fluorescent, halogen or other light sources for prolonged periods of time can also be photodegraded.

 

In the test, the light source simulated by the xenon lamp is only the spectrum of 300nm to 800nm. Impurity microbes, these can also cause corrosion of materials! There must be many other inconsistencies that lead to it not having a definitive answer. If your product has a standard, it should have a similar statement on how much the product will be damaged if exposed to too much light. 500 hours is equivalent to one year in actual time, this is just for reference. Xenon arc weathering testers can be used to select new materials, improve existing materials, or evaluate changes in durability after structural changes in materials.

 

Precautions in the use of water-cooled xenon lamp aging tester:

 

R & D engineers of Standard International Group (HK) Limited suggest that please remember the precautions of the xenon arc aging tester, which can avoid the failure of the machine due to improper operation, and the correct maintenance method can prolong the service life of the machine.

 

1. During operation, please do not open the door unless necessary, otherwise it may cause adverse consequences.

2. In order to provide protection for the test product and the operator, please check the water pressure controller and the water level of the circulating water tank regularly.

3. Only by installing the wet bulb test cloth correctly can the correct relative humidity be measured.

4. Please read the manual carefully before operating the machine.
