VG95218-2 UV Aging Test Chamber B-ZW Climatic Chamber UV-A Mathine Lab Drying Oven

Description:

 A UV aging test chamber is a specialized piece of equipment used in laboratories to simulate the effects of long-term exposure to UV radiation on materials, products, and samples. The chamber exposes the test sample to controlled amounts of UV radiation, simulating the effects of prolonged exposure to sunlight or other sources of UV radiation. This allows researchers to study the effects of UV radiation on various materials, including plastics, textiles, and coatings, and to develop products that can withstand UV exposure over time. UV aging test chambers are used in a variety of industries, including automotive, aerospace, and construction, to test the durability and performance of materials under UV exposure.

There are several different types of fluorescent UV lamps that have unique spectral characteristics. Fluorescent black lights, referred to as UV-A lamps, are available with peak emissions of 340 nm – 370 nm (e.g., UVA-340 and UVA-351). In the UVA-340 lamp, the short wavelength irradiance simulates that of direct solar radiation below 325 nm. Fluorescent UV-B lamps (UVB-313), with a peak around 313 nm, have nearly all of their energy concentrated between 280 nm and 360 nm. A large percentage is at wavelengths shorter than what is present in natural sunlight. There is very little radiation with wavelengths longer than 360 nm. Reversals in the stability ranking of materials have often been reported between laboratory accelerated and outdoor tests when the accelerated test uses UV-B lamps. This occurs because of the large amount of short wavelength UV and the lack of long wavelength UV and visible radiation; the mechanisms of degradation may be significantly different from those of the “natural” tests.

The UV aging test chamber simulates the effect of sunlight with fluorescent ultraviolet(UV) lamps and carry out these circles automatically.While it simulates rain and dew with condensing humidity or waterspray.In a few days or weeks,the UV can reproduce the damage that occurs over months or years outdoors.The damages include fading,color change,chalking,cracking,crazing,embrittlement,strength loss,etc.The test data can help you to select the new materials or improve the performance of materials. Chamber cover introduces the two-way flip type for easy opening and closing.The spec-imen and the shelf constitute the trapezidal inner wall of the chamber.

Main functions:

UV QUV test machine, the UV lamp can simulate the effect of the sun, condensation and water spray system can simulate the effect of rain and dew. the temperature can be controlled at the process of testing. A typical test cycle is usually testing at UV radiation of high temperature and the 100% humidity at dark; Typically used in paint and coatings, automotive, plastic products, wood products, glue, etc.

Main feature:

1, simulated sunlight

2, UV lamp type

3, moisture condensation environment

4, the temperature control in each cycle, the temperature can be controlled at a set value.

5, the water spray system for some applications, the water spray can better simulate the end use of the environmental conditions.

6, irradiation intensity control: optional matching light intensity control option available to accurately type and reproducible results;
