The xenon lamp aging resistance test is a comprehensive climate test device. In addition to the weather aging test, it can also test the light resistance of high-score materials, that is, polymer materials are exposed to artificial light sources that simulate the sunlight spectrum through glass Light resistance. Simulate and strengthen the test from the main climatic factors of light energy, temperature, rainfall or condensation, and humidity; use xenon arc lamps that can simulate the full sunlight spectrum to reproduce the destructive light waves that exist in different environments; xenon lamp weather resistance test The box can provide corresponding environmental simulation and accelerated testing for scientific research, product development and quality control. It can be used for new material selection, improvement of existing materials or evaluation of durability changes after material composition changes; suitable for plastics, rubber, paint , Paint, ink, paper, medicine, food, cosmetics, textiles, auto parts, packaging materials, construction materials, electrical and electrical products, etc.
Structure:
The shell of the xenon lamp weather resistance test box is A3 steel plate electrostatic sprayed, and the liner is high-quality SUS304 stainless steel plate. The radiation source is an air-cooled full solar spectrum xenon lamp. The irradiation intensity is automatically tracked. The temperature of the blackboard can be accurately controlled. The irradiation cycle, dark cycle, and spray cycle can be set freely according to relevant test standards or customer requirements. The controller of the xenon lamp weather resistance test box can choose imported touch screen controller or intelligent digital display controller according to the user's own needs. The sample holder of the xenon lamp weather resistance test box is made of corrosion-resistant stainless steel material, and the flat drawer or drum type sample holder can be selected according to the user's requirements. The YSL-SN-900 xenon lamp weather resistance test box is equipped with an irradiation sensor, which can make timely corrections to the drop in light energy caused by the aging of the lamp or any other changes. The irradiation sensor allows you to choose the appropriate light irradiation during the test. The irradiation sensor can continuously monitor the light irradiation intensity in the irradiation room, and by adjusting the power of the lamp tube, the irradiation intensity can be accurately maintained at the operating setting value. The water spraying cycle of YSL-SN-900 can effectively simulate the rapid temperature change and rain erosion process. Due to frequent erosion from rain, the paint layer of wood, including paint and colorants, will appear to corrode accordingly. Recent research results show that this rain layer is washed away, thereby directly exposing the material itself to the damaging effects of UV and moisture. The rain spray function can reproduce such environmental conditions and enhance the weathering test of certain paints.
