Xenon lamp aging test chamber can simulate the full sun spectrum of xenon arc
lamp to reproduce the existence of different environments under the
destructive light waves, scientific research, product development and
quality control to provide the appropriate environmental simulation and
accelerated test, also known as "sun radiation protection test (LP
/ SN-500), water-cooled xenon lamp (LP / SN-500), desktop xenon lamp
(TXE), the difference is that the test temperature, humidity, accuracy , Time and so on. Is an indispensable test instrument in the aging test chamber series.
Xenon
lamp weather resistance test is an important means of optimizing the
composition of the product in the process of scientific research and
production. It is also an important content of product quality
inspection. Application materials such as paint, plastic,
aluminum-plastic plate and automobile safety glass are all required to
do weather test. The
main factors that cause the aging of the material are sun and moisture,
and the weather resistance testing machine can simulate the damage
caused by sunlight, rain and dew. Atlas xenon lamp aging tester using xenon lamp to simulate the effect of
sunlight, the use of condensed moisture simulation of rain and dew, the
measured material placed in a certain temperature of the light and
moisture alternating cycle procedures for testing, with a few days or
weeks Reproducible outdoor months and even years of harm, artificial
accelerated aging test data can help to select new materials, improve
the existing materials, and evaluate how the changes in the formulation
affect the durability of the product.
Xenon lamp aging test chamber test conditions:The
relative humidity used for the test shall be agreed by the parties
concerned, but it is best to use any of the following conditions: (50 ±
5)% or (65% 5)% (Note: because the temperature of the different colors
and thicknesses is different The relative humidity inside the chamber is not necessarily equal to the relative humidity of the sample adjacent to the air.1. Test sample fixture on the test stand, face the fluorescent lamp When
the sample sample is not filled, you need to use the blackboard to fill
the sample rack to keep the test chamber wall closed.
2. Light can be selected for each cycle of condensation 4H light, 4H condensation or 8H light, 4H condensation two cycles.
3. Test temperature. Light can be used when 50,60,70 ℃ three kinds of temperature, priority is recommended to use 60 ℃; condensation stage temperature of 50 ℃, the temperature tolerance uniformity of ± 3 ℃.
4. After the twentieth light 400 ~ 450H, each row of tubes need to replace a fluorescent lamp, the other lamp in accordance with the lamp cycle and replace the way to compensate for the loss caused by lamp aging. This mode of operation to ensure that each lamp life of 1600 ~ 1800H.
5. When replacing the lamp, dry the water tray and clean it to avoid the formation of scale.
6. Test samples and performance evaluation:
7. Appearance evaluation: the appearance of the coating is mainly the assessment of plastic and rubber, if necessary, can also be the appearance of assessment, inspection items are mainly gloss, color change, powder, spots, blister, crack and dimensional stability. Should try to use the instrument for quantitative project testing, such as gloss, color difference meter (optional).
8. Mechanical and other properties of the assessment: general rubber material tensile strength, elongation, hardness measurement, plastic measurement of impact strength, elongation at break, tensile strength, bending strength, if necessary, other performance test items can be specified (optional).
9. Standard configuration: 12 UV lamp; 21 sets of sample rack
10. Use the working environment: ambient temperature: 15 ~ 35 ℃; equipment around 300mm above the wall
