The ultraviolet aging test chamber is a laboratory equipment that simulates the impact of ultraviolet radiation on materials in the natural environment. The weathering resistance, durability and anti-aging performance of materials are evaluated through the accelerated aging process. The core principle is to use high-intensity ultraviolet light sources to simulate the ultraviolet components in sunlight, combined with precise temperature and humidity control systems, to reproduce the aging effect of materials outdoors for years or even decades in a short period of time.

The equipment structure usually consists of a box, ultraviolet light source, temperature and humidity control system, sample rack, and intelligent control system. The box is made of high-quality stainless steel or A3 steel plate spray treated, and the inner liner is made of imported stainless steel material to ensure sealing and corrosion resistance; The ultraviolet light source is distributed on both sides of the box, and convenient operation is achieved through a bidirectional flip design; The temperature and humidity control system adopts an internal tank type heating and a fully stainless steel evaporative humidifier to ensure temperature uniformity (± 1 ℃) and humidity stability (≥ 95% RH); The sample rack is made of aluminum alloy and can hold 20 standard size samples (404 × 105mm) at the same time, maintaining a parallel distance of 50mm from the lamp tube to optimize irradiation uniformity; The intelligent control system supports independent or alternating cycle programming of lighting and condensation, with a maximum time setting of 1000 hours, and is equipped with blackboard thermometer and irradiation intensity calibration function.

The application areas cover key industries such as materials science, automotive manufacturing, electronics and electrical engineering, building materials, and new energy. In the automotive industry, this device can simulate sunlight, ultraviolet radiation, and high temperature environments to test the weather resistance of car paint, plastic parts, and rubber seals; In the electronic and electrical field, it is used to evaluate the anti-aging performance of polymer materials such as mobile phone casings, wires and cables; The construction industry verifies the durability of coatings, plastic doors and windows by simulating changes in ultraviolet radiation and temperature and humidity; In the field of new energy, the focus is on UV stability testing of photovoltaic materials. In addition, industries such as plastics, coatings, textile printing and dyeing also widely use this equipment to optimize product formulas and enhance market competitiveness. one
