النشرة الإخبارية UV test chamber

Ultraviolet light test chamber, also known as UV-ultraviolet weather resistance aging test chamber, is a fluorescent UV lamp imported from the United States (ATLAS) as a light source by using the natural UV Radiation is simulated sunlight and then by humidification system simulates the function of condensed water and simulates rainy weather by spraying to conduct accelerated weatherability tests on materials to obtain the material weatherability results. The product's aging resistance is tested by artificially reproducing environmental conditions such as UV rays, high temperature, high humidity, condensation, rain and darkness in natural climates.

Ultraviolet Light Test Box mainly provides UV aging test for plastics, coatings, plastics, adhesives, advertising materials, roofing materials, printing inks, textiles and other industries toevaluate the test To test the photostability and shelf life of the test product or to evaluate the performance of the test product. It is an indispensable and important test method in the whole process of new product development, prototype testing and product qualification testing.

Ultraviolet rays in sunlight are the main factor affecting durability of most materials. Our QINSUN technology uses UV lamps to simulate the short-wavelength ultraviolet portion of sunlight, which produces very little visible light, and infrared spectrum energy. Our QINSUN UV Accelerated Aging Tester | UV artificial accelerated aging test chamber can select different wavelength UV lamps according to different test needs, because each UV lamp has different total energy and wavelength of ultraviolet radiation. Normally, UV lamps can be divided into UVA and UVB.

UVA-340 Lamps: UVA-340 lamps are good at simulating short-wavelength ultraviolet light in real sunlight; H. from 365 nanometers to the wellen length range where sunlight cuts off at 295 nanometers.

UVB-313 lamp tube: The short-wavelength ultraviolet light emitted by the UVB-313 lamp tube is stronger than the sun's ultraviolet sunlight that normally irradiates the earth's surface, which can significantly accelerate the aging of materials. However, the tube can cause impractical damage to certain materials. UVB-313 lamps are mainly used for quality control, research and development or to perform tests on materials with the highest weather resistance.
