In the past two years, everyone was enveloped in the fear of the epidemic. They did not go out and locked down the city, and frantically bought uv disinfection products and other protective products. With the deepening of research on the new coronavirus, experts are constantly updating detection methods, as well as popularizing and operating guidance for various protective measures.
In numerous disinfection means, disinfectant, alcohol and other products are often used at ordinary times, and ultraviolet disinfection lamp is less exposed to in life, that this method tube after all whether to use? What should we pay attention to when using it? Let’s talk more about the UV Germicidal lamp and UV Sterilization Lam today.
The first thing to be sure of is that disinfection with UV lamps is effective for the novel Corona virus. Early in the SARS period, experts from the National Institute for Viral Disease Control and Prevention of the Chinese Center for Disease Control and Prevention found that the SARS virus could be killed by irradiating the covid 19 with ultraviolet light with an intensity greater than 90μW/cm2 for 30 minutes. Novel Corona virus Protocols for the Diagnosis and Treatment of Pneumonia in Novel Covid 19 Infections (Trial Corona virus Fifth Edition) indicate that novel Corona virus is sensitive to ULTRAVIOLET light. Recent studies have found that novel Corona virus is correlated with SARS covid 19. Therefore, scientific and rational use of ULTRAVIOLET light can effectively inactivate corona virus in theory.
What is the principle of ultraviolet lamp disinfection? In simple terms, it uses high-energy ultraviolet light to disrupt the structure of DNA, depriving it of its ability to reproduce and self-replicate, thereby killing bacteria. And in the process of ultraviolet lamp sterilization, will produce ozone, ozone itself can gradually destroy the structure of the virus from the outside to the inside, so as to achieve the effect of sterilization. Therefore, the use of ultraviolet disinfection lamp, can be said to be double sterilization.
Although ultraviolet lamp disinfection effect is good, but improper use can cause damage to human body. Because this is in use, want to make sure indoor nobody, and close door window. After irradiation for enough time (depending on the energy intensity of the lamp, refer to the product instructions), open the window for ventilation before anyone enters. This is because uv lamp in the use of ozone, ozone concentration is too high will make people dizziness, nausea and other symptoms, and even cause respiratory tract lesions. And long-term improper use of ultraviolet light will cause harm to the eyes, if long-term exposure to the skin, light redness, itching, and even skin cancer.
Generally speaking, the use of UV light for disinfection is effective for the novel Coronavirus, but its effect is limited, the scope of exposure is small and the coverage of radiation is limited, and improper use can cause physical damage. Therefore, people should exercise extreme caution when using it. Finally, remind everybody, in this very period, the use of any means of disinfection all need to learn the correct operation, such ability in the case of security to protect themselves, to protect family members, good today for ultraviolet disinfection, such as introduction to this, hope the outbreak quickly in the past, we can go to the outdoor to enjoy the natural “uv lamp”.
