Ka'ida da Aikace-aikacen Haifuwar UV Ultraviolet: Haifuwar UV yana da dogon tarihi.A shekara ta 1903, masanin kimiyyar Danish Niels Finsen ya ba da shawarar maganin hoto na zamani bisa ka'idar haifuwar haske kuma an ba shi lambar yabo ta Nobel a fannin ilimin halittar jiki ko magani.A cikin karnin da ya gabata, haifuwar UV ta taka muhimmiyar rawa wajen rigakafi da magance cututtuka masu saurin yaduwa a cikin bil'adama, irin su "kwari biyu" da suka faru a Arewacin Amirka a cikin 1990s, SARS a China a 2003, da MERS a cikin shekaru. Gabas ta Tsakiya a cikin 2012. Kwanan nan, saboda mummunan barkewar sabon coronavirus (2019-nCoV) a kasar Sin, an gane hasken UV don babban tasiri wajen kashe ƙwayoyin cuta, ya zama muhimmiyar hanya don magance yaduwar cutar da kuma tabbatar da cewa yaduwa. lafiyar rai.
Ƙa'idar Sterilization UV: An raba hasken UV zuwa A-band (315 zuwa 400 nm), B-band (280 zuwa 315 nm), C-band (200 zuwa 280 nm), da kuma UV (100-200 nm) bisa ga kewayon tsayinsa.Gabaɗaya, ana amfani da hasken UV na C-band don haifuwa.Bayan an fallasa su zuwa hasken C-band UV, nucleic acid (RNA da DNA) a cikin ƙwayoyin cuta suna ɗaukar makamashin UV photons, suna haifar da nau'ikan tushe don polymerize da hana haɗin furotin, wanda ke sa ƙwayoyin cuta ba su iya haifuwa, don haka cimma nasarar dalilin haifuwa.
Amfanin Haifuwar UV:
1) Haifuwar UV ba ta haifar da ragowar wakilai ko samfura masu guba, guje wa gurɓataccen gurɓataccen yanayi da oxidation ko lalata abubuwan da ake haifuwa.
2) Kayan aikin haifuwa na UV yana da sauƙin shigarwa da kulawa, yana da ingantaccen aiki, kuma yana da ƙarancin farashi.Magungunan sinadarai na gargajiya irin su chlorine, chlorine dioxide, ozone, da peracetic acid suna da guba sosai, masu ƙonewa, fashewa, ko abubuwa masu lalata waɗanda ke buƙatar ƙaƙƙarfan buƙatun haifuwa na musamman don samarwa, sufuri, ajiya, da amfani.
3) Haifuwar UV yana da faɗin bakan kuma yana da inganci sosai, yana iya kashe yawancin ƙwayoyin cuta da suka haɗa da protozoa, ƙwayoyin cuta, ƙwayoyin cuta, da dai sauransu. Adadin radiation na 40 mJ/cm2 (yawanci ana iya cimmawa lokacin da fitilu na mercury low-matsi suna haskakawa a nesa daga nesa. mita daya na minti daya) na iya kashe kashi 99.99% na kwayoyin cuta.
Haifuwar UV tana da faffadan bakan da ingantaccen tasiri na ƙwayoyin cuta akan yawancin ƙwayoyin cuta, gami da sabon coronavirus (2019-nCoV).Idan aka kwatanta da magungunan sinadarai na gargajiya, haifuwar UV tana da fa'idodin rashin gurɓataccen gurɓataccen abu na biyu, ingantaccen aiki, da ingantaccen aiki wajen kashe ƙwayoyin cuta, waɗanda za su iya zama babbar ƙima wajen shawo kan cutar.
