Yuchuang synthetic donated 10000 sets of 59 second disinfection products

According to the 59 second WeChat official account, after 18 hours of long-distance transportation, 3 vehicles loaded with 10000 sets of 59 seconds disinfection products worth 4 million yuan arrived at the designated warehouse of the Wuhan Red Cross.

Novel coronavirus is a "love" sent to medical staff who are fighting for the new coronavirus in Wuhan. It is used to solve the problem of disinfection of mobile phone, glasses and infrared thermometers, stethoscope and sphygmomanometer cuff.

Guangmingyuan donated 700 wall mounted ultraviolet sterilizers

According to WeChat's official account of Guangming yuan technology, in January 25th, the Guangming source Polytron Technologies Inc organization staff worked overtime to donate 700 wall mounted UV disinfection devices to Wuhan.

This batch of ultraviolet sterilizers have been distributed to 672 Hospital of Wuhan City, emergency department of the Third Hospital of Wuhan City, Xiangyang people's Hospital, Jingzhou Central Hospital, Chibi CDC, people's Hospital of Wuhan University, respiratory department of Dongxihu District People's Hospital of Wuhan.

Donation of 500 uvc-led multifunctional sterilizers

According to deep purple science and technology news, Shenzhen Shanbo technology overcame the difficulties of logistics and transportation, and sent more than 500 sets of the latest deep ultraviolet LED multifunctional sterilizer to the Wuhan Red Cross Society to fight against the epidemic of pneumonia in Wuhan.

The sterilizer is small in size and easy to carry. It has the function of solar charging and endurance. It is used to meet the all-weather sterilization needs of medical staff, patients or sensitive groups.

Novel coronavirus is highly effective in killing ultraviolet rays from the above UV disinfection products. The UV light emitting diode (UVC-LED) is based on III-V semiconductor AlGaN material, which produces ultraviolet light of 270~280 nm UVC.DUVTek uvc-led lamp bead products have the honor to participate in the fight against pneumonia virus.


During the SARS period, the research team of Dong Xiaoping, an expert from the Institute for viral disease control and prevention of the Chinese Center for Disease Control and prevention, found that the SARS virus was sensitive to heat radiation and UVC. The SARS virus could be killed in 30 minutes after the coronavirus was irradiated with UVC with an intensity greater than 90 μ w / cm? 2. The researchers also simulated natural sunlight in the laboratory to test the ability of ultraviolet rays in sunlight to kill coronavirus. The results showed that the coronavirus in vitro could be killed in 3 hours under the sunny weather of 10:00 a.m. in Beijing, i.e. the ultraviolet light intensity was 4 ~ 5 μ w / cm ~ 2. But if it is cloudy, the killing ability of ultraviolet rays in sunlight will be greatly reduced.


The researchers also found that as the temperature increased, the viability of the coronavirus decreased significantly. Under the condition of serum-free culture, heating to 75 ℃ for 30 minutes can kill the coronavirus. The recent thermal radiation experiment of 2019 ncov shows that it can be killed in 30 minutes at 56 ℃. Therefore, the radiation dose of UVC to kill 2019 ncov may be less than that of SARS CoV, but the specific dose needs further study and confirmation.

According to the measured data of DUVTek, the ultraviolet radiation intensity of a single 11.17mw uvc-led lamp bead at a distance of 5cm is 578 μ w / cm? 2. This means it takes less than five minutes to kill the SARS virus.
