- Do not expose the ultraviolet light source to people to avoid damage. Ultraviolet rays have the most obvious effect on human skin and eyes. The human body will produce skin redness, itching, and allergic papules when exposed to a short period of time; prolonged exposure will cause serious damage to skin tissues, and sufficient dose of radiation may even cause cancer of the skin. Exposure to ultraviolet rays is also very harmful to human eyes. Short-term large-dose exposure can cause eyes to swell, shed tears, and fail to open the eyes. Long-term exposure to ultraviolet radiation can cause cataracts or even blindness.
2. When disinfecting the surface of articles with ultraviolet rays, the irradiation surface should be directly irradiated with ultraviolet rays, and a sufficient irradiation dose should be achieved. Due to the linear propagation of light, when it is blocked by an object, it will reflect, penetrate or absorb. Ultraviolet disinfection requires that the wattage of the ultraviolet Light per cubic meter space is ≥ 1.5W, and the irradiation time is generally 30 to 60 minutes. It also stipulates that the intensity of ultraviolet radiation should not be less than 70ūW / cm2, otherwise the sterilization effect is poor or ineffective, and the purpose of disinfection cannot be achieved.
3. The suitable temperature range for UV disinfection is 20 ℃ ~ 40 ℃, too high or too low temperature will affect the disinfection effect. When disinfecting indoor air with ultraviolet light, the room should be kept clean and dry to reduce dust and water mist. When the temperature is lower than 20 ° C or higher than 40 ° C and the relative humidity is greater than 60%, the exposure time should be properly extended.
4. In the application, attention should also be paid to the cleaning and cleaning of the Light tube. When the new Light is used, 75% alcohol gauze can be used to wipe the Light tube to remove the pollution of the Light tube with dust and oil stains. During use, wipe regularly and do a good job of cleaning the Light, so as not to affect the purple transmission rate and radiation intensity.
