M'mafakitale ena, monga biopharmaceuticals, mafakitale azakudya, ndi zina zambiri, kugwiritsa ntchito ndi kapangidwe ka nyali za ultraviolet ndikofunikira.Pakuwunikira kwa chipinda choyera, chinthu chimodzi chomwe sichinganyalanyazidwe ndichoti muganizire kukhazikitsa nyali za ultraviolet.Ultraviolet sterilization ndi yotsekera pamwamba.Ndi chete, si poizoni ndipo alibe zotsalira pa njira yolera yotseketsa.Ndizopanda ndalama, zosinthika komanso zosavuta, choncho zimakhala ndi ntchito zambiri.Itha kugwiritsidwa ntchito m'zipinda zosabala, zipinda zanyama ndi malo opangira ma labotale omwe amayenera kutsekedwa m'mashopu onyamula katundu m'makampani opanga mankhwala, komanso pakulongedza ndi kudzaza zokambirana m'makampani azakudya;Pazachipatala ndi zaumoyo, zitha kugwiritsidwa ntchito muzipinda zopangira opaleshoni, mawodi apadera ndi zochitika zina.Zingadziwike molingana ndi zosowa za eni ake kaya kukhazikitsa nyali za ultraviolet .
1. Poyerekeza ndi njira zina monga kutsekereza kutentha, kutsekereza kwa ozoni, kutsekereza kwa radiation, ndi kutseketsa kwa mankhwala, kutsekereza kwa ultraviolet kuli ndi zabwino zake:
a.Kuwala kwa Ultraviolet ndi kothandiza polimbana ndi mitundu yonse ya mabakiteriya ndipo ndi muyeso woletsa kupha anthu ambiri.
b.Zilibe pafupifupi chilichonse pa chinthu chotsekereza (chinthu choyatsidwa).
c.Ikhoza kutsekeredwa mosalekeza komanso ikhoza kutsekedwa pamaso pa ogwira ntchito.
d.Ndalama zotsika mtengo, zotsika mtengo zogwirira ntchito, komanso zosavuta kugwiritsa ntchito.
2. Mphamvu ya bactericidal ya kuwala kwa ultraviolet:
Mabakiteriya ndi mtundu wa tizilombo toyambitsa matenda.Tizilombo tating'onoting'ono timakhala ndi ma nucleic acid.Pambuyo kuyamwa cheza mphamvu ya ultraviolet walitsa, ndi nucleic zidulo adzachititsa photochemical kuwonongeka, potero kupha tizilombo.Kuwala kwa Ultraviolet ndi mafunde osawoneka ndi ma elekitiromagineti okhala ndi utali wamfupi kuposa kuwala kowoneka bwino kwa violet, wokhala ndi kutalika kwa 136 ~ 390nm.Mwa iwo, cheza cha ultraviolet chokhala ndi kutalika kwa 253.7nm chimakhala ndi bakiteriya.Nyali za Germicidal zimachokera pa izi ndipo zimapanga kuwala kwa ultraviolet kwa 253.7nm.Kutalika kwa mayamwidwe a nucleic acid ndi 250 ~ 260nm, kotero nyali za ultraviolet germicidal zimakhala ndi bactericidal effect.Komabe, kuthekera kolowera kwa cheza cha ultraviolet kuzinthu zambiri ndi chofooka kwambiri, ndipo chitha kugwiritsidwa ntchito pochotsa zinthu pamwamba pa zinthu, ndipo alibe mphamvu yowumitsa pazigawo zomwe sizinawonekere.Pochotsa ziwiya ndi zinthu zina, mbali zonse za kumtunda, m'munsi, kumanzere, ndi kumanja ziyenera kuyatsidwa, ndipo mphamvu yoletsa kutulutsa cheza cha ultraviolet sichingasungidwe kwa nthawi yayitali, kotero kutseketsa kuyenera kuchitika pafupipafupi malinga ndi mkhalidwe weniweniwo.
3. Mphamvu zowunikira komanso kutsekereza zotsatira:
Mphamvu yotulutsa ma radiation imasiyanasiyana ndi kutentha, chinyezi, liwiro la mphepo ndi zinthu zina zamalo omwe amagwiritsidwa ntchito.Pamene kutentha yozungulira ndi otsika, linanena bungwe mphamvu nawonso otsika.Pamene chinyezi chikuwonjezeka, mphamvu yake yotseketsa idzachepanso.Nyali za UV nthawi zambiri zimapangidwa kutengera chinyezi chapafupi ndi 60%.Chinyezi cham'nyumba chikachulukira, kuchuluka kwa kuyatsa kuyeneranso kuchulukira molingana chifukwa mphamvu yotseketsa imachepa.Mwachitsanzo, chinyezi chikakhala 70%, 80%, ndi 90%, kuti mukwaniritse zoletsa zomwezo, kuchuluka kwa ma radiation kuyenera kuwonjezeka ndi 50%, 80%, ndi 90% motsatana.Kuthamanga kwa mphepo kumakhudzanso mphamvu yotulutsa.Kuphatikiza apo, popeza mphamvu ya bactericidal ya kuwala kwa ultraviolet imasiyanasiyana ndi mitundu yosiyanasiyana ya mabakiteriya, kuchuluka kwa kuwala kwa ultraviolet kuyenera kusiyanasiyana kwa mitundu yosiyanasiyana ya mabakiteriya.Mwachitsanzo, mphamvu ya magetsi imene imagwiritsidwa ntchito popha bowa ndi yaikulu kuwirikiza 40 mpaka 50 kuposa imene imapha mabakiteriya.Chifukwa chake, poganizira za kutsekereza kwa nyali za ultraviolet germicidal, zotsatira za kutalika kwa unsembe sizinganyalanyazidwe.Mphamvu yowumitsa ya nyali za ultraviolet imawola pakapita nthawi.Mphamvu yotulutsa ya 100b imatengedwa ngati mphamvu yovotera, ndipo nthawi yogwiritsira ntchito nyali ya ultraviolet mpaka 70% ya mphamvu yovotera imatengedwa ngati moyo wamba.Nthawi yogwiritsira ntchito nyali ya ultraviolet ikadutsa moyo wamba, zotsatira zomwe zikuyembekezeredwa sizingakwaniritsidwe ndipo ziyenera kusinthidwa panthawiyi.Nthawi zambiri, moyo wapakati wa nyali zapakhomo za ultraviolet ndi 2000h.Mphamvu yowumitsa ya cheza ya ultraviolet imatsimikiziridwa ndi kuchuluka kwake (kuchuluka kwa ma radiation a ultraviolet germicidal nyali kumatha kutchedwanso kuchuluka kwa mzere), ndipo kuchuluka kwa ma radiation nthawi zonse kumakhala kofanana ndi mphamvu ya radiation yochulukitsidwa ndi nthawi ya radiation, kotero iyenera Kuchulukitsa kwa radiation, ndikofunikira kuwonjezera mphamvu ya radiation kapena kuwonjezera nthawi ya radiation.
