1. Disinfection of broad-spectrum cultural relics:
Studies have shown that the killing effect of the virus is mainly affected by the function, transmission and transmission of the class (, virus subclass, etc.). , Bacteria such as Mycobacterium, Cholera, Pseudomonas, Salmonella, Enterobacter, Murine, Shigella, Staphylococcus, Escherichia coli swarm, influenza virus, poliovirus, rotavirus, tobacco leaf virus, tobacco leaf virus, etc.
2. Novel coronavirus infection protection
From the perspective of infectious diseases, the infection of 2019-nCoV to 2019-nCoV is the transmission range and infection range of the main virus through the widespread transmission of 2019-nCoV [6]. From the perspective of the transmission route, the protection against viral infection of the 2019 novel coronavirus is considered from the following three aspects:
Infection source angle: isolation.
All aspects: physical protection or spreading the kill.
Susceptible crowd: Improve immunity.
Wearing a lamp/disinfectant for disinfection is a method of disinfecting masks and disinfectants, a method of causing pollution to the environment, a method of causing environmental pollution, etc. method. A comparison method between killing lamp disinfection and alcohol, in spray disinfection lamp disinfection.
Point: Both belong to broad-spectrum anti-corrosion methods.
: There are differences in usage and operation.
3. Coronavirus and the efficacy of tobacco lamps
There are many kinds of coronaviruses, the virus that causes common flu, SARS (SARS-CoV) caused by 2003, and the new coronavirus (2019-nCoV) discovered this time are all coronaviruses, which are caused by different types of coronaviruses. and clinical manifestations are also different [7]. The 2019-nCoV discovered this time is the seventh known coronavirus that infects humans [8].
The virus is sensitive to previous thermal images. Killing behavior [9], therefore, the role of 2019-nCoV as a new type of coronavirus can be damaged.
The dose of UV light that can kill the virus is related to the following factors:
The total amount of UV exposure depends on the exposure time and exposure intensity;
The in vitro environmental conditions in which the virus is exposed, including ambient temperature and humidity;
Viruses and attachments penetrate outside the body and UV radiation.
Precautions and recommendations for using UV light.
4. Warm reminder:
While UV radiation can kill bacteria and viruses, its radiation can also damage human skin and eyes. Therefore, when installing and using ultraviolet radiation, it is necessary to ensure that the radiation dose can achieve the effect of sterilization and disinfection, and it should also be ensured that: use it under unmanned conditions (avoid contact with the human body)
Taking the central light of 253.7nm as the representative, it has a broad-spectrum killing effect on lamp extinction and virus. Validated on SARS. The new experiment in 22019 shows that under the action of an unmanned environment, the display is used with the lights off, and the new arc extinguishing lamp and virus lamp are used when the lights are off. Disinfection effect can achieve the purpose of protecting infection through transmission
During this special period, we need 95nm antiviral and anti-microbial viruses. Effectively kill 9.9% of bacteria and viruses, and can be widely used for disinfection and disinfection of 75nm rooms!
