How to disinfect UV lamps
With the increase in health awareness, ultraviolet disinfection technology has received widespread attention due to its efficient sterilization properties. This article will introduce in detail the disinfection principle, usage and precautions of ultraviolet lamps, and attach hot topic data in the past 10 days for reference.
1. Principle of UV lamp disinfection
Ultraviolet lamps destroy the DNA/RNA structure of microorganisms by emitting UVC band (200-280nm), causing them to lose their ability to reproduce. Common application scenarios include:
| Applicable scenarios | Recommended exposure time |
|---|---|
| Household items surface | 15-30 minutes |
| medical device | 30-60 minutes |
| air disinfection | The room is sealed for 1 hour |
2. Detailed explanation of operating steps
1.Security protection: Wear goggles to avoid direct exposure of skin and eyes
2.Environmental preparation: Clean and disinfect object surfaces, close doors and windows
3.Parameter settings: Adjust power according to space volume (1.5W/cubic meter)
4.Post-disinfection treatment: Ventilate for more than 30 minutes before entering
3. Hot topics related to disinfection in the past 10 days

4. Important matters needing attention
1.Material restrictions: Plastic/rubber products are prone to aging and should not be exposed to long-term exposure.
2.safe distance: Keep a distance of more than 2 meters. Ozone lamps require additional ventilation.
3.life monitoring: After 1000 hours of use, the intensity of the lamp drops by 30% and needs to be replaced.
5. Frequently Asked Questions
Q: Can ultraviolet light kill the new coronavirus?
A: WHO confirms that UVC can effectively inactivate coronavirus, but it needs to reach a dose of 30mJ/cm².
Q: Why is there a peculiar smell after disinfection?
A: It may be due to ozone residue. It is recommended to choose ozone-free lamps or sufficient ventilation.
Through the rational use of ultraviolet disinfection technology and other cleaning methods, pathogenic microorganisms in the environment can be effectively reduced. It is recommended that users choose disinfection equipment with appropriate power based on actual needs and strictly follow operating specifications.
