Overview

The UV weather resistant aging chamber is a device that simulates sunlight UV radiation, condensation moisture, and temperature changes to perform accelerated aging tests on materials. Its core function is to quickly reproduce the environmental damage effects of outdoor environments for months to years, helping users evaluate the weather resistance of materials, screen new materials, or improve existing material formulations. This device is widely used in the fields of paint and coatings, automotive industry, plastic products, wood products, adhesives, etc. It can simulate various aging phenomena such as fading, cracking, peeling, and strength reduction

Product Details

Working principle and key technologies of UV climate aging resistant box

Simulate environmental elements

lighting simulationUsing fluorescent ultraviolet lamps (UVA or UVB type) to simulate shortwave ultraviolet radiation in sunlight, with UVB-313 tubes accelerating aging (suitable for weather resistant material testing) and UVA-351 tubes more closely fitting indoor lighting scenes through window glass.
Wet simulationSimulate the erosion of materials by dew and rainwater through condensation cycle (heating the reservoir to generate hot steam, making the humidity in the testing room reach 100%) or water spray system. It is recommended to last at least 4 hours for a single condensation cycle.
temperature controlMaintain high temperature environments during the illumination and condensation stages, such as 50 ℃ -75 ℃ during the UV irradiation stage and 40 ℃ -60 ℃ during the condensation stage. Blackboard thermometers are used to monitor the surface temperature of the sample in real-time.

UV resistant weather aging chamberCharacteristics of the experimental process

The testing cycle is alternately carried out by UV exposure and condensation/spraying, such as the combination of "light exposure (high temperature) → condensation (dark and high humidity)" cycle, and the entire process is automatically controlled. By shortening the testing cycle (several days to several weeks), it is possible to predict long-term outdoor aging.

Box structure:

The box adopts an integrated structure, consisting of three parts: upper, middle, and lower. The upper part is the control panel, the middle is the experimental work area, and the lower part is the electrical and mechanical room

The inner liner adopts1.2mmSUS304Stainless steel plate, shell made of1.2mmThick stainless steel plate spray coating

There is a water storage tank at the bottom of the studio, equipped with water heating and air heating systems

The circulation system consists of fans and air ducts, which increase air flow and significantly improve the temperature uniformity of the test chamber

UVA-340It simulates the ultraviolet rays of sunlight and can simulate the critical short wavelength range of sunlight spectrum, that is, the wavelength range is295to360nmThe spectrum.UVA-340Only produced in sunlight that can be foundUVSpectrum of wavelengths.
UVB-313Used for accelerated testing, it can quickly provide experimental results using short wavesUVMore than what is usually found on the surface of the Earth at presentUVLight waves are stronger. Although these are much shorter than natural wavesUVLight can accelerate experiments, but at the same time, it can also cause unrealistic degradation and damage to certain materials.
