313 UV Lamp Irradiation Test ChamberSimulate the damage caused by the sun's ultraviolet light and test the weatherability of the material by exposing the tested material to light at a controlled high temperature. It uses UV lamps to simulate the radiant effect of sunlight. In just a few days or weeks, UV radiation equipment can reproduce the damage that lasts months or even years outdoors, including fading, discoloration, tarnishing, powdering, cracking, tearing, wrinkling, such as blistering, embrittlement, strength reduction, oxidation, etc. The test results can be used to select new materials, existing materialsn Improve or evaluate changes in material formulations.

Ultraviolet (UV) light makes up only 5% of sunlight, but it is the main light factor that reduces the durability of outdoor products. Several different UV lamps are available and in most cases only simulated shortwave UV light is required. Most of these UV lamps produce ultraviolet light rather than visible and infrared light. Lamps differ primarily in the total UV energy they produce in their respective wavelength ranges. Different lamps lead to different test results. Actual exposure application environment can indicate what kind of UV lamp should be used.

UVA-340 is an excellent choice to simulate the UV rays of sunlight in reality. UVA-340 can simulate the spectrum of sunlight in the short-wavelength range, that is, the spectrum with a Wavelength range of 295-360 nm. UVA- 340 only produces spectrum at UV wavelengths.

UVB-313, is used for a high level of accelerated testing. UVB-313 has a shorter wavelength with a wavelength range of 280-315n, which can be faster than UVA-340 Type displays the test results accordingly.

The standard defines afluorescent UV lamp emitting wavelengths below 300 nm and less than 2% of the total light energy output, commonly referred to as UV-A lamps; Emission A fluorescent UV lamp whose light energy below 300 nm accounts for more than 10% of the total light energy output, commonly referred to as a UV-B lamp.

LQ-UV1 is single-function, has only a single UV light function

LQ-UV3-A has three functions including light + condensation + spray because the test box is the environment in the Outdoor simulates the outdoor environment has sunlight, rainy days and humidity. For weather like dew, the three functions are designed to simulate a variety of weather and climates very well, such as UV light is designed to simulate the ultraviolet rays of sunlight, Spray is designed to simulate rainy weather, Condensation is designed to simulate humidification to produce high humidity and dewdrops.< /p>

LQ-UV3-B, thisalso a three-function, but the specification is different from the standard disk, thissuitable for non-standard size and irregular size of the cut products are placed, and the feetFunction is the same as that of LQ-UV3-A, but the place where the products are placed is different. It adopts the style of a shelf suitable for irregular products.
