The quality of the quartz glass used in the UV weathering test chamber has a significant impact on the lifespan of the UV lamp. High-quality quartz glass is characterized by high purity, no internal bubbles, and a smooth surface. Since the wall temperature often operates above 600°C, impurities in low-purity glass can cause the surface to vaporize, creating tiny pits that interfere with the UV radiation emitted through the tube wall. In contrast, domestic quartz tubes may visually show bubbles within the walls, which can reduce the efficiency of UV light transmission. These air bubbles can create high-pressure gas pockets at elevated temperatures, potentially leading to explosions that damage the tube. The electrode material in most UV lamps used in weathering chambers consists of tungsten wire coated with a layer of zirconate or other cathode-emitting materials. The ability of the tungsten wire and cathode materials to resist aging and withstand high temperatures directly affects the overall life of the electrode.
Materials are substances that humans use to create objects, devices, components, machines, or other products. However, not all substances can be classified as materials. Only those that meet specific functional and structural requirements for manufacturing purposes qualify as materials. Understanding the properties and performance of these materials is crucial in ensuring the reliability and longevity of equipment like UV weathering test chambers.
