Use ultraviolet lamp tube to sterilize indoor
(ward), for leukemia patients are more familiar. But ultraviolet disinfection
has a lot of attention, do you know?
Characteristics of ultraviolet lamp sterilization
1. After the lights up, the indoor dirty air is gradually cleaned by the action of ozone and ultraviolet rays, so the lamp constantly supplies the source of fresh air, and the free bacteria in the air are also killed when ozone decomposes. Can prevent cold and other air-mediated infectious diseases, prevent hepatitis, tuberculosis infection.
2. deodorant and mildew proof. In the bedroom, the bathroom on this light, not only can deodorize, but also can kill flies, mosquitoes and other larvae. In a dark and humid room, prevent items from getting moldy.
3. pure physical sterilization without secondary pollution. Because UV disinfection technology does not need to add any chemical, it will not cause secondary pollution to the surrounding environment.
4. ultraviolet disinfection technology, disinfection efficiency is the highest of all disinfection means.
5. can effectively prevent epidemic diseases such as SARS、H5N1、H1N1、 encephalitis.
Precautions for the Use of Ultraviolet Lamps
1. ultraviolet light can only travel along a straight line, weak penetration, any paper, lead glass, plastic will greatly reduce the intensity of exposure. Therefore, disinfection should be as far as possible to make the disinfection site fully exposed to ultraviolet light.
2. wipe the lamp regularly.In the process of use, the surface of the lamp tube should be kept clean, once a week with alcohol cotton ball wipe, found that there is dust on the surface of the lamp tube, oil should be wiped at any time, so as not to affect the ultraviolet penetration rate and irradiation intensity.
3. indoor air disinfection: required not less than 1.5 per ㎡ W, irradiation time not less than 30 min, lamp less than 2 m. from the ground The room should be kept clean and dry to reduce dust and water mist. When the temperature is less than 20℃ or higher than 40℃, the irradiation time should be extended when the relative humidity is greater than 60.
4. surface disinfection: lamp tube should not exceed 1 meter from the surface of the object, should be directly irradiated using the irradiated surface, and should reach sufficient exposure dose (100000 UW.s/cm2 when killing bacterial spores)
5. in the use of ultraviolet lamp irradiation disinfection, should be prohibited from being present, in order to avoid direct ultraviolet radiation on the eyes and skin of people and injury, not to mention the eyes of the lit lamp. PS： there is no need to worry about the differences in the light-emitting principles of small, mosquito-killing ultraviolet lamps used in restaurants and homes.
6. in places where people are active, do not generally use ozone lamp tubes, because ozone will promote the condensation of hemoglobin in the human body, resulting in insufficient oxygen supply, dizziness, nausea, and affect health, especially when ozone concentration reaches 0.3 ppm (mg/m2)>, will cause harm to the human body.
7. ultraviolet rays kill organic cells, do not long-term exposure to pets and plants.
Do not use ultraviolet lamp as lighting 8., disinfection time 30 minutes to 1 hour is appropriate, do not advocate long time on ultraviolet lamp.
After sterilizing the room 9., please open the window for more than 5 minutes.
10. The lamp has a general life of 1000 hours and is monitored semi-annually for radiation intensity and should be replaced when it is below 70 uw/cm2.
11. Do not place damaged or used lamps beside people or throw them into places where there is water to avoid contamination of water sources.
The sterilization blind area of ultraviolet lamp tube:
1. can only sterilize the upper surface of the object (food), not the lower surface of the object;
2. multiple objects overlap, they can not sterilize the surfaces of overlapping parts;
3. can only sterilize the external surface of the object, can not sterilize the object inside! That is to say, ultraviolet (invisible light) can not be irradiated in the place can not play the role of sterilization and disinfection.
