The bus is a bus, a city bus, namely a bus or a bus, is a typical bus type of a large or medium-sized bus in a bus, is a commercial vehicle which is designed and equipped for specially solving urban and suburban transportation, can be provided with an air conditioner to heat up or cool down in summer and winter, and needs to seal the interior of the bus in the process of heating and cooling.
UVC wave band, wavelength 200 ~ 275nm, also known as short wave sterilization ultraviolet ray. It has the weakest penetrating power and can not penetrate most transparent glass and plastics. The short-wave ultraviolet rays contained in sunlight are almost completely absorbed by the ozone layer. The short wave ultraviolet ray has great harm to human body, can burn skin after short time irradiation, and can cause large area skin separation after long time or high intensity irradiation. The ultraviolet germicidal lamp emits UVC short-wave ultraviolet rays. UVD band, wavelength 100 ~ 200nm, also known as vacuum ultraviolet. Ultraviolet sterilization principle: ultraviolet sterilization is the purpose of sterilizing bacteria by irradiating ultraviolet rays to destroy and change the DNA (deoxyribonucleic acid) structure of microorganisms so that the bacteria die immediately or cannot reproduce offspring. The true bactericidal action is UVC ultraviolet ray, because the C-band ultraviolet ray is easily absorbed by the DNA of the organism, and the best ultraviolet ray is about 253.7 nm. Ultraviolet sterilization belongs to a pure physical disinfection method, has the advantages of simplicity, convenience, broad spectrum, high efficiency, no secondary pollution, convenience in management, realization of automation and the like, and the application range of ultraviolet sterilization is continuously expanded along with the release of various novel ultraviolet lamp tubes.
Nano Silver (Nano Silver) is a metallic Silver simple substance with a Nano-scale particle size. The particle size of the nano silver is mostly about 25 nanometers, and the nano silver has strong inhibiting and killing effects on dozens of pathogenic microorganisms such as escherichia coli, gonococcus, chlamydia trachomatis and the like, and can not generate drug resistance. The cotton socks made of the nano silver and the combed cotton fiber have good antibacterial and deodorant effects.
