Depth Analysis of Xenon Arc Chamber Rotating Drum Holder and Flat Shelf

xenon arc chamber through the simulation of natural sunlight in the ultraviolet, visible light and infrared spectrum components, accelerated aging of various materials such as plastics, rubber, coatings, textiles, etc., to assess the material in the long-term light, temperature and humidity changes and other environmental factors under the performance stability. The LIB xenon arc chamber can control the light intensity, humidity, temperature and spray system, etc., to more truly restore the actual use of the product.

Now, let's focus on the sample shelf of the xenon arc chamber, and take a look at the characteristics of these two mainstream sample shelves: rotary drum shelf and plate shelf.

From the perspective of illumination uniformity parameters, the rotating drum frame has certain advantages. The rotating drum frame adopts a 360 degree all-round rotation design. During the test, the sample constantly changes its position and Angle with the rotation of the drum body, so that the xenon lamp light source can irradiate relatively evenly to the various surfaces of the sample. The rotating drum shelf of the LIB Xenon lamp test chamber has three layers, and under standard test conditions, the light intensity deviation of different positions can be controlled within ±10%.

However, flat shelves are relatively weak in this regard. Due to the static state of the plate, the xenon lamp light source of the LIB plate sample holder is located at the top of the studio, and there are two layers of detachable shelves in the studio, and the relative position of the sample is fixed, and the light intensity of the center area and the edge area will have a certain degree of deviation when testing a large area of the sample.

In terms of the convenience parameters of sample installation and disassembly, the flat shelf performs better. The flat shelf uses simple card slots or jigs to hold the sample, and the operator can easily place the sample on the shelf and fix and remove it with intuitive operation. Greatly improve the overall efficiency of the test, especially for the need to frequently change the sample for multiple tests of the experimental scene, such as scientific research institutions to new paint samples for phased aging effect test, can quickly complete the replacement of samples, saving time and cost.

In contrast, the standard type of the sample of the rotating drum holder has higher requirements, and the installation and disassembly are more complicated. The LIB rotating drum holder can simultaneously hold 42 rectangular samples of 95mm and 180mm in width. Because the samples need to be mounted inside the rotating drum, the operator needs to attach the samples one by one to the internal holders and ensure that the samples do not fall off during the rotation process.

In summary, the two sample holder has its own characteristics, in the selection of xenon lamp test box shelf, it is necessary to consider the characteristics of the sample, the test purpose and the convenience of operation and other factors, weighing the advantages and disadvantages of the rotary drum holder and the plate shelf in the light uniformity, installation convenience and sample damage risk and other key parameters, in order to select the most suitable test needs of the program. To ensure the accuracy and reliability of the test results.

The LIB xenon arc chamber (rotating drum holder type) uses an advanced drive system to ensure smooth rotation and accurate control of speed, and the material of the SUS304 shelf has good corrosion resistance and high temperature resistance. The internal air circulation system makes the temperature and humidity distribution more uniform, further improving the accuracy and reliability of the test. https://www.libtest.com/products/xenon-arc-chamber/

The LIB xenon arc chamber (flat panel shelf) focuses on stability and versatility. The shelf surface is specially treated to ensure good flatness and low reflectivity, which reduces the interference of the sample test results due to the light reflected by the shelf.
