UV lamp quartz glass is the key material used in ultraviolet sterilization lamps. Unlike ordinary glass or plastic, quartz glass offers exceptional UV transmittance, high-temperature resistance, and long-term durability. This makes it the preferred choice for applications such as air purification, water treatment, and medical disinfection. In this article, we explore why UV lamps must use quartz glass and what benefits it provides.
1. High UV Transmittance for Maximum Sterilization
Quartz glass can transmit over 85% of UV-C light at 254nm, while normal glass blocks most UV wavelengths.
Advantages:
- Stronger sterilization effect
- Improved energy efficiency
- Shorter exposure time
This makes UV lamp quartz glass ideal for water disinfection systems, HVAC air purifiers, and laboratory equipment.
2. Excellent High-Temperature Resistance
UV lamps generate a significant amount of heat during operation. Quartz glass can withstand continuous temperatures of up to 1200°C, short-term exposure to 1450°C, and has a softening point of 1700°C, far exceeding ordinary glass materials.
3. Superior UV Aging Resistance
Quartz glass remains stable under long-term UV exposure. It does not yellow, crack, or degrade, ensuring long lamp life and low maintenance costs.
4. High Purity for Safe Applications
Made from high-purity SiO₂, quartz glass does not release contaminants, making it ideal for use in:
- Medical devices
- Food processing
- Water purification systems
- Semiconductor cleanrooms
