How to disinfect the UV lamp? How to disinfect the UV lamp? Ultraviolet is a kind of low-energy electromagnetic wave. Because of its good sterilization effect, it is widely used in medical, sanitation and epidemic prevention, food industry, pharmaceutical industry and other sectors. However, how to use the ultraviolet lamp
correctly to ensure its sterilization effect, extend the service life of the lamp tube, and avoid accidental injury, requires every operator to master first. The principle of ultraviolet disinfection lamps
is to use ultraviolet radiation to cause photolysis and denaturation of bacterial proteins, and the amino acids, nucleic acids, and enzymes of the bacteria are destroyed and die. At the same time, when ultraviolet rays pass through the air, the oxygen in the air is ionized to produce ozone, which strengthens the sterilization effect. Ultraviolet rays are mostly used for disinfection of air and object surfaces, with a wavelength of 2573A. For air disinfection, the effective distance does not exceed Zm, the irradiation time is 30-60min, and the article disinfection, the effective distance is 25-60cm, the irradiation time is 20-30min, and the timer starts from the light on 5-7min (the light needs to be preheated for a certain period of time, In order to ionize the oxygen in the air to produce ozone). What should I pay attention to when using UV lamps? (1) The staff should make work arrangements before ultraviolet disinfection lamps to avoid walking in the room during the disinfection process, which will affect the disinfection effect and receive unnecessary exposure; when the monitoring nurse monitors the intensity of the lamp, due to the large number of lamps When monitoring, you must wear protective goggles and protective clothing; in wards with ultraviolet lamps, the switch of the ultraviolet lamp must be separated from other ordinary lamps or be marked, and the patient and family members must be explained to the patient and family members when receiving the patient. Turn on the ultraviolet light to avoid adverse consequences. (2) During use, the surface of the UV lamp should be kept clean. Generally, wipe it with an alcohol cotton ball once every two weeks. When dust or oil stains are found on the surface of the lamp tube, wipe it at any time. (3) When disinfecting indoor air with ultraviolet lamps. The room should be kept clean and dry to reduce dust and water mist. The temperature should be lower than 20°C or higher than 40°C, and the relative humidity should be extended appropriately when the relative humidity is greater than 60%. (4) When using ultraviolet rays to disinfect the surface of an article, the irradiated surface should be directly irradiated by ultraviolet rays, and a sufficient radiation dose should be achieved. (5) Do not irradiate people with ultraviolet light source to avoid damage. (6) The ultraviolet intensity meter is calibrated at least once a year. When you use ultraviolet lamps, you should pay attention to some details of the use. Only scientific use can guarantee the life of the lighting. The above is the relevant introduction on how to disinfect the UV lamp and what to pay attention to when using the UV lamp. When using the UV lamp, you should pay attention to avoiding long-term use, and you must pay attention to keeping the lighting clean and dry during use.
