ʻO ke kumu a me ka hoʻohana ʻana o UV Ultraviolet Sterilization Principle: He moʻolelo lōʻihi ko UV sterilization.I ka makahiki 1903, ua hāʻawi ka ʻepekema Denemaka ʻo Niels Finsen i ka phototherapy hou e pili ana i ke kumu o ka sterilization māmā a ua loaʻa iā ia ka makana Nobel i ka Physiology a i ʻole Medicine.I ka makahiki i hala iho nei, ua hana koʻikoʻi ka UV sterilization i ka pale ʻana a me ka mālama ʻana i nā maʻi maʻi maʻi maʻi i loko o ke kanaka, e like me ka hanana "ʻelua insects" ma ʻAmelika ʻAmelika i ka makahiki 1990, SARS ma Kina i ka makahiki 2003, a me MERS i ka makahiki. Hikina Hikina i ka makahiki 2012. ʻO kēia manawa, ma muli o ka puka nui ʻana o ka coronavirus hou (2019-nCoV) ma Kina, ua ʻike ʻia ke kukui UV no kona kiʻekiʻe kiʻekiʻe i ka pepehi ʻana i nā maʻi maʻi, lilo i mea koʻikoʻi no ka pale ʻana i ka laha o ka maʻi maʻi a me ka hōʻoia ʻana. palekana ola.
ʻO ke kumu o ka hoʻomaʻamaʻa ʻana o UV: Ua hoʻokaʻawale ʻia ke kukui UV i A-band (315 a 400 nm), B-band (280 a 315 nm), C-band (200 a 280 nm), a me ka vacuum UV (100-200 nm) e like me ka kona laulā nalu.ʻO ka maʻamau, hoʻohana ʻia ke kukui UV C-band no ka sterilization.Ma hope o ka ʻike ʻia ʻana i ka kukui UV C-band, ʻo ka nucleic acid (RNA a me DNA) i loko o nā microorganisms e hoʻomoʻi i ka ikehu o nā kiʻi UV, e hoʻoneʻe ai i nā hui kumu i polymerize a pale i ka synthesis protein, kahi e hiki ʻole ai i nā microorganism ke hana hou, no laila e loaʻa ai ka kumu o ka sterilization.
ʻO nā pono o ka UV Sterilization:
1) ʻAʻole hoʻopuka ʻo UV sterilization i nā mea koena a i ʻole nā huahana ʻawaʻawa, e pale aku i ka pollution lua i ke kaiapuni a me ka oxidation a i ʻole ka corrosion o nā mea i sterilized.
2) He mea maʻalahi ka hoʻokomo a mālama ʻana i nā mea hana UV sterilization, he hana hilinaʻi, a he haʻahaʻa haʻahaʻa.ʻO nā mea hoʻomaʻemaʻe kemika maʻamau e like me ka chlorine, chlorine dioxide, ozone, a me peracetic acid he mea ʻawaʻawa, ʻā, pahū, a i ʻole nā mea corrosive e koi ai i nā koi sterilization koʻikoʻi no ka hana ʻana, ka lawe ʻana, ka mālama ʻana, a me ka hoʻohana.
3) ʻO ka sterilization o UV he ākea ākea a maikaʻi loa, hiki ke pepehi i ka hapa nui o nā meaola pathogenic e like me ka protozoa, bacteria, virus, etc. hoʻokahi mika no hoʻokahi minuke) hiki ke pepehi i 99.99% o nā microorganism pathogenic.
He hopena bactericidal ākea ka UV sterilization i ka hapa nui o nā microorganism pathogenic, me ka coronavirus hou (2019-nCoV).Ke hoʻohālikelike ʻia me nā sterilizers kemika kahiko, ʻo ka UV sterilization ka maikaʻi o ka ʻole o ka pollution lua, ka hana hilinaʻi, a me ka hana kiʻekiʻe i ka pepehi ʻana i nā microorganism, hiki ke lilo i mea waiwai nui i ka hoʻomalu ʻana i ka maʻi maʻi.
