Reliable aging test data can be accurately related to product weather resistance (anti-aging) Sexual prediction and help materials and formulations screening, optimize. It is possible to reproduce the destruction of several months or years in addition to several months: including fading, discoloration, brightness, powder, crack, variation, embrittlement, strength decrease, and oxidation.Ultraviolet Wearing Test Machine
Outdoor product light degradation is mainly caused by ultraviolet light.
According to different test conditions, there are several different ultraviolet lamps to choose from. QUV fluorescent ultrafield lamp can simulate the most important short-wave ultraviolet light in the sun, and reproduce the aging of material physical properties caused by light.
All QUV UV weathering test models offer thermal coagulation wet cycles, a harsh and real humid exposure environment. In general, products exposed to outdoor are often in a humid state in humidity for 15 hours. QUV UV weathering testing machine provides two moisture simulation methods. Because some application conditions also require water spray to achieve the actual effect, some QUV models can run a condensation cycle and run water spray cycle.
QUV / SE UV weathering test machine is the most commonly used QUV model, The use of QUV / SE UV weathering test functions can be performed at a lower priceis equipped with a sun eye radial illuminance control system that can accurately monitor UV irradiance.
has condensing function to simulate outdoor moisture erosion.
Provides fast, reproducible test, longer tube life and calibration according to ISO metrological standard requirements.
QUV / SPRAY UV weathering test machine
QUV / SPRAY UV weathering test machine is basically the same as the standard QUV / SE UV weathering test machine When the spray cycle is used, deionized water is recommended. is equipped with a water sprinkler, including nozzles, pipelines, control and drainage devices.
Short-time spray can simulate thermal shock, long spray can be used to simulate mechanical erosion caused by rainwater scouring.QUV / SPARY UV weathering test machine can achieve ultraviolet light, spray or condensing function.
QUV / BASICUltraviolet weather testing machine
QS-LabCompany recommends that only QUV / BASIC is only used while making comparison exposure tests, that is, at the same time, the test sample and reference in the same trial machine Sample exposure comparative experiments.
QUV / BASIC UV weathering test machine is suitable for laboratory with limited budget. The irradiance is controlled by regular replacement lamp and the rotation tube position. The QUV / BASIC UV weathering test machine has a condensing function analog moisture, but does not have water spray function. The high-radiation illuminance test cannot be performed because it is not equipped with the sun eye radial illuminance control system, and there is no automatic adjustment or calibration.
QUV / CW UV weathering test machineMany industries require cool white light to perform indoor product light resistance test, QUV / CW can reproduce this indoor Light environment.
Compliance with indoor light resistance test standards such as ISO, ANSI and ASTM.
It is equipped with a sun eye radial illuminance control system to monitor the light intensity of the cold fluorescent lamp.
An indoor lighting environment is used to simulate the indoor lighting environment, such as fluorescent lamps commonly used in the office.UV weathering test machine related accessories
* UVB-313 lamp tube. UVB-313 short wave emitted UV is often irradiated in the solar ultraviolet rays in the surface of the earth, so that the maximum acceleration material can be maximized. However, the lamp may cause non-practical damage to certain materials. The UVB-313 lamp is mainly used for quality control and research development, or a material operating test of high weather resistance.
UVA-340 lamp tube
* UVA-340 lamp. UVA-340 lamp can be extremely simulated from short-wave ultraviolet light in the sun, ie from 365 nm to the wavelength range of 295 nanometers of the sunlight cutoff. The UVA-340 tube of the QUV aging test function can actually simulate the short-band section of the sun, so that the QUV aging test function simulates the ultraviolet portion in the sun. It is therefore particularly suitable for comparing the performance difference between different types of polymers and stabilizers. It is the best tube for material correlation research.

UV weathering testing machine and xenon weather testing machine selection method
These two testing equipment test principles completely different. Xenon lamp test chamber simulates all spectroscopy of sunlight, including ultraviolet (UV), visible light and infrared (IR). The xenon spectrum is basically in the range of the sunlight spectrum in the range of 295 nm to 800 nm.
On the other hand, the QUV cannot simulate full spectral sunlight. It is based on the principle that the short-band 300 to 400 nm of ultraviolet rays is the most important cause of aging damage. However, there will be no power for a long wavelength.
QS-lab simulates all the spectrum of sunlight, which is used to test many products, which are sensitive to long-wave bands, visible light and infrared rays for ultraviolet rays.
Of course, regardless of how the test device is effective, if its purchase price is too high, then it does not actually apply value. That's why buy prices, operating costs, and maintenance costs are some important factors that cannot be ignored. These factors should also be considered when considering the advantages of a testing device.
