Affected by the COVID-19, ultraviolet disinfection lamp in the sterilization products are very popular on the market, and the ultraviolet ray sterilizing lamp mainly divided into: high voltage, medium voltage and low voltage three kinds of disinfection, ultraviolet disinfection lamp, is to use ultraviolet light to kill bacteria breeding, buds, branches of bacillus, coronavirus, fungi, such as rickettsia and chlamydia bacteria, so ultraviolet disinfection lamp has been used in what respect?
(1) ultraviolet disinfection lamp in the surface of the application of sterilization
This sterilizer is mainly used in the fields of food, electronics, semiconductor, liquid crystal display, plasma TV, crystal vibrator, precision device, chemical industry, medicine, health care, biology, beverage, agriculture and so on. Because the UV light source is irradiated on the surface of food, materials, etc., it has a fast and efficient bactericidal effect without pollution, and can maintain the high quality of products. Therefore, it is faster than the traditional sterilization method, on the surface of the sterilization of the speed of sterilization, but also can be carried out continuous processing and batch processing, and in the operation of simple and convenient, environmental protection without secondary pollution and other characteristics.
(2) Application of ultraviolet disinfection lamp in water treatment
Mainly USES the ultraviolet disinfection lamp to carry on the water treatment method: the immersion type and the overcurrent two kinds, among them if directly puts the ultraviolet lamp into the water is the immersion type; However, if the uv lamp is put into the casing for use, it is overcurrent. At present, the method of overcurrent is basically adopted. Because the principle of overcurrent equipment is the water flow through the pump pressure, so the flow can be through the ultraviolet quartz casing, but because of the ultraviolet light produced by the ultraviolet disinfection of the water, sterilization. So its characteristic is the speed of water flow is very fast, the time that flows in quartz jacket commonly is not more than 1s, because this asks the ultraviolet intensity of antiseptic lamp wants very high.
(3) Application of ultraviolet disinfection lamp in medical treatment
This mainly used ultraviolet disinfection lamp to sterilize the air, and here the use of static direct exposure to the air and the flow of air disinfection method these two methods. Because static air is direct illuminate method basically USES ultraviolet ray disinfection lamp direct illuminate to undertake antiseptic, but drawback is the place that does not illuminate namely is disinfected cannot, and the person cannot be in the spot when disinfecting. And the flow of air disinfection law is the use of dynamic air disinfection machine, this disinfection machine can just fill the shortcomings of the above two points. The principle of mobile air sterilizer is through the indoor air for mutual circulation, and then the air sterilization to achieve the purpose of indoor air disinfection. The structure of this sterilizer is basically the housing of household air conditioning. The mobile air sterilizer, previously used only in hospitals, has been widely used in homes, offices and bulletin boards. The function above also changes the diversification, for example: can apply in the health care, the prevention function, becomes the health related product.
How long does it take to sterilize ultraviolet disinfection lamp?
Doors and Windows should be closed when used for air disinfection, each disinfection time shall not be less than 60 minutes, since the light on 5-7 minutes after the timing, the irradiation process is prohibited to enter the room, because the work needs to enter, should stop irradiation, especially young unmarried nurses remember this.
When disinfecting articles, spread the articles or hang them, expand the irradiation surface, the effective distance is one meter, irradiation not less than 30 minutes.
Application of uv ultraviolet sterilization effect of bacteria. Method of e. coli, proteus, staphylococcus aureus, staphylococcus aureus, bacillus subtilis, white light 20 min, 30 min, respectively 40 min, 50 min, 60 min. Results different bacterial resistance to ultraviolet, 30 min after the ultraviolet irradiation, escherichia coli and proteus all death irradiation 40 min, staphylococcus aureus, white staphylococcus all death irradiation 60 min, bacillus subtilis all death conclusion ultraviolet disinfection, exposure time should be greater than 60 min.
Ultraviolet disinfection lamp disinfection needs 60 minutes. Please use disinfection with caution disinfection lamp of ultraviolet ray. Ultraviolet disinfection lamp is the short-wave ultraviolet ray (UVC) that USES the 254nm that mercury lamp gives out to be disinfected mostly, this kind of short-wave ultraviolet ray energy is bigger, if do not have protection, can cause direct harm to human body, if the eye, skin is burned seriously, cause skin cancer even.
