Core Performance Advantages
- Exceptional High-Temperature Resistance: Withstands continuous operating temperatures of 300–800℃ (varies by purity), adapting to UV lamp’s heat generation during long-term use.
- Superior Electrical Insulation: High breakdown voltage and insulation resistance, isolating electrodes from external components to prevent leakage and ensure safe operation.
- Corrosion Resistance: Resists erosion from ozone (a byproduct of UV lamp operation) and chemical vapors, avoiding material degradation and extending service life.
- Dimensional Stability: Low thermal expansion coefficient, maintaining precise fit with the lamp tube and electrodes even under temperature fluctuations.
- Good Thermal Conductivity: Quickly dissipates heat from electrodes to the external environment, protecting the lamp’s core components from overheating.
