Structure of xenon lamp aging test chamber

Structure of xenon lamp aging tester
1. Test box
The test case is made of corrosion-resistant material, and its internal device includes the radiation source and sample frame of the filter system.
2. Radiation source and filtration system.
Radiation source is composed of one or more of the xenon lamp, they produce a radiation filter filtered light system, make the irradiance in the sample frame with the relative spectral power distribution of plane of the sun's ultraviolet and visible radiation approximate or with 3 mm glass filtration of solar ultraviolet and visible radiation approximation.
3. Test box body adjustment system.
In order to maintain the black mark or blackboard temperature of the test case, the dust air should be circulated in the box, and its temperature and humidity are controlled. The temperature and relative humidity of the air in the test box are controlled by the temperature and humidity sensor, and the sensor is not directly exposed to radiation. The regulation of relative humidity must be distilled water or softened water.
4. The device for wetting the sample.
The test samples used throughout the wetting process should be wetted in one of two ways:
A) spray on the surface;
B) the sample is immersed in water in the test case.
If the sample is rotated around the radiant source, the nozzle of the water jet should be able to arrange each sample as required.
The conductivity of distilled water or softened water used for wetting should be less than 2 mu S/cm and the distillation residue is less than 1mg/kg.
5. Sample frame
The sample frame shall be made of inert material.
6. Black standard/blackboard thermometer.
In dry segments, use a black standard thermometer or chalkboard thermometer to measure the temperature of the sample surface.
7. Radiation meter.
The irradiance E and exposure radiant energy H on the surface of the test box should be measured by the radiation meter of the photoelectric receiver with a spherical field and a good cosine curve. The radiation meter shall be calibrated according to the spectral distribution listed in schedule B1, and the calibration value shall be checked according to the manufacturer's own manual.

Tinuvin 1130: An Excellent UV Absorber

 In the field of the chemical industry, UV absorbers play a crucial role, particularly in protecting materials from UV damage. Today, we will delve into a highly regarded UV absorber—Tinuvin 1130. Tinuvin 1130 : chemical name: 3-(3-(2H-benzotriazole-2-yl)-4-hydroxy-5-tert-butyl phenyl)propionic acid polyethylene glycol 300 ester; CAS login number: 104810-48-2. This product is an exceptional UV absorber that offers numerous benefits due to its unique properties. One of the standout features of Tinuvin 1130 is its excellent weather resistance. It has a strong ability to absorb ultraviolet rays, particularly those with wavelengths ranging from 290-400nm. This effectively prevents coatings, plastics, rubber, and other materials from being damaged by UV rays, thereby maintaining the performance and appearance stability of these materials and extending their service life. In addition, Tinuvin 1130 exhibits good compatibility. It is easy to emulsify in water-based systems and can be...

Air-cooled Xenon Lamp Aging Tester

  The air-cooled xenon lamp aging tester is a device that uses an air-cooled system to dissipate heat and a xenon lamp to simulate ultraviolet light, visible light and infrared light in natural sunlight to perform accelerated aging tests on materials. It is commonly used in industries such as automobiles, coatings, plastics, rubber, and textiles. It can evaluate the aging resistance of materials under the combined effects of long-term light, temperature, humidity and other environmental factors in a relatively short period of time, helping companies improve product quality, extend service life, and optimize product anti-aging formulas and processes. Structural composition:  The main body is a test chamber, equipped with a xenon lamp and a matching optical filter system to simulate sunlight of different wavelengths, as well as temperature, humidity, lighting time and other control and adjustment devices, as well as an observation window and a sample rack. Working principle: The...

The Structure of Hexapod Tumble Tester

The Hexapod Tumbler Tester is a popular apparatus used in the evaluation of the appearance retention of carpets. Drum – constructed of Nylon or other like material and capped by a lid that is secured by a latching device. The drum and lid have a locating groove to hold the specimen backing sheet flat to the inner wall of the drum. A photograph of a typical drum is show in Photograph 1 and Photograph 2. The drum dimensions are:   Internal Diameter: 12 ± 0.18 in. (302 ± 5mm) Wall Thickness :0.3 in. approx. (8 mm approx.) Internal Depth: 8.2 ± 0.2 in. (207 ± 5 mm)  Driving System - cradles the drum on rollers and keeps the axis of the drum level, and rotates the drum at 35 ± 2 rpm (3.6 ± 0.2 rad/s). The driving direction reverses after approximately 500 revolutions.  After the 500 rotations the unit will stop and stand stationary for approximately 5 to 15 seconds, then begin rotating in the opposite direction. After 2000 rotations the unit will stop and w...
