Ka kōrero te akoranga ngaio ki a koe mehemea e N95 ipurangiroto i muri i te disinfection? He pai ake te tikanga o te disinfection?

wā:2020-05-18 Ngā Taunga:

Aerosol te pānga o te pānga ki te novel coronavirus. Ina coughs te tūroro, sneezes, , wawautia rānei, breathes rānei, i horahia e rātau he whakahekenga micron-whakarahia aerosols ki te rangi. He nui nga aerosols iti e toe ana i te rangi mō te wā roa, te nuinga o nga tāngata i te mōrea whakapokenga. Na reira, mau kua waiho tētahi o ngā mea e te hīpoki hei ārai, hei whakahaere hoki i te novel coronavirus te pānga.



Filtration te tōtika o N95 respirator i 0.3 waewae rangiwhiti konutai pūhaumāota aerosol he nui ake i te 95%, ka taea te ārai i te uhi o te huaketo. E pangai ana te N95 o te kōeke i ipurangiroto i te worldwide o te outbreak. I tēnei kēhi, te whakamahinga o te ipurangiroto i muri i disinfection kiko tikanga ake. Stanford te whare wānanga me 4C i te arotake o ngā tikanga disinfection rerekē mō te rewa-pūhia nonwovens, te filtration o te uho mo N95 ipurangiroto.


N95 hīpoki rewa pūhia nonwoven papanape hanganga me te filtration hoahoa


I kōwhiria e te utuhia te wera nui (75 ℃, 30 min), wai vapor (e pā ana ki 15 hk runga i te wai kōhua,min min), 75% ethanol rongoā pipīa, me te whare patuhuakita rehu (kei roto 2% konutai hypochlorite) (0.3 ~ 0.5 mL) kia rima hoki nga momo disinfection i whakamahia hei ultraviolet irradiation o rewa-pūhia nonwovens disposable disinfects, ka whakamātau i tana huringa mahinga. Ko ngā hua i whakaaturia e te mahinga filtration o rewa-pūhia nonwovens kōhungahunga tino i muri i te ethanol rumakanga me te whare patuhuakita maimoa, i te disinfection o ētahi atu aratuka kāore i te filtration te tōtika o rewa-pūhia nonwovens.


Ngā pānga whakawera, mamaoa me ultraviolet te rama i ngā āhuatanga filtration o rewa-pūhia nonwovens


Utuhia ka ako anō te sterilization i ngā pānga o ngā hātepe maha ki ngā āhuatanga filtration-rewa pūhia, i rā e rātau mā te hauraro tiketike, wai vapor, me ultraviolet parawhiti. Ko ngā hua i whakaaturia e te filtration o rewa-pūhia nonwovens kōhungahunga kia nui tahuri i muri i 5 ngā wā o te wai vapor porohita maimoa, i te filtration o te mahinga rewa-pūhia nonwovens e toe ana i muri 10 ngā wā o te pāmahana nui me te ultraviolet rama irradiation.


Te pānga ultraviolet i runga i ngā āhuatanga o rewa-pūhia nonwovens


Ko ngā pānga o te pipiwai me te pāmahana i runga i ngā āhuatanga filtration o rewa-pūhia nonwovens i ako. Ka whakaatu ngā hua i te 85°C, i muri i 20 he wā maimoa i roto i ngā pipiwai rerekē, ko te mahinga filtration o rewa-pūhia nonwovens kihai i tino te hekenga, a kihai i tino te hanganga. Ahakoa 50 ngā wā maimoa i te 85°C me 30% haumākū, filtration te mahinga o rewa-pūhia nonwovens anake kōhungahunga. I te wa ano, i hoatu te maimoa ōrite ki te hīpoki N95, a kihai i filtration te mahinga o te tino. Heoi, he tepenga whakarunga te 125 °C mo te pāmahana o whakawera maimoa, tērā pea, kei te kati te pāmahana ki te pito whakakoero o te matū i tēnei wā, a ka arahina te huringa o ana microstructure ki te hekenga electrostatic electrots.


Te huringa o te mahinga filtration i muri i te whakawera o te rewa spraying me te hīpoki i te pāmahana rerekē me te pipiwai


I runga anō i te otinga, e taunaki ana kia kaua te whakamahi waipiro, patuhuakita, hopi me te wai ki te horoi me te disinfect N95 ipurangiroto i te tukanga o te whakamahinga. Ultraviolet disinfection me te disinfection-teitei, he tikanga kōwhiringa disinfection. Heoi, nā te ngotonga iti o ultraviolet parawhiti me te āhua o te bactericidal, high-temperature treatment below 100°He pānga iti ake ki te rewa-pūhia nonwovens ka taea te rānei mō ngā wā maha. Na reite tino maimoa i raro i te 100 100°C te aratuka disinfection pai mō N95 ipurangiroto.
