Ko te horapa o te hauhautanga tētahi o ngā huarahi e horapa ai te mate korona hou. Ina maremare, ina tihe, ina kōrero, ina manawa rānei te tūroro, ka horahia e rātou ngā hauhautanga iti-rahi e kawe ana i te huaketo ki te rangi. He maha ngā hauhautanga iti e noho roa ana i te rangi, ā, ka tūpono te tangata ki te pangia e te mate. Nō reira, ko te mau i te kopare kanohi kua noho hei tētahi o ngā huarahi whai hua hei ārai me te whakahaere i te horapa o te mate korona hou.

Neke atu i te 95% te whai huatanga o te tātari o te manawa N95 i runga i te aerosol konutai pūhaumāota he 0.3 putu te whānui, ā, ka taea e tēnei te aukati i te horapa o te huaketo. Kua iti haere ngā kopare tiaki hauora N95 puta noa i te ao mai i te pakarutanga mai. I tēnei wā, he mea nui te whakamahinga anō o ngā kopare i muri i te patu huakita. Nō nā tata nei i arotakehia e te Whare Wānanga o Stanford me te 4C Air ngā tikanga patu huakita rerekē mō ngā mea kore-whatu rewa-pūhia, te rauemi tātari matua mō ngā kopare N95.

Te hanganga papanga kore-whatu me te hoahoa tātari o te kopare N95 kua rewa

I whiriwhiria e ngā kairangahau te pāmahana teitei (75 ℃, 30 meneti), te mamaoa wai (tata ki te 15 cm i runga ake i te wai kohua, 10 meneti), te otinga etanoru 75% kua rumakina, me te rehu patu huakita whare (kei roto ko te 2% konutai hauhāoraiti) (0.3 ~ 0.5 mL) me ngā momo patu huakita e rima e whakamahia whānuitia ana pērā i te whakamahana ultraviolet o te tukatuka patu huakita kore-whatu rewa, kātahi ka whakamātau i tōna huringa mahi. I whakaatuhia e ngā hua he tino heke te mahi tātari o ngā mea kore-whatu rewa i muri i te rumakina etanoru me te maimoatanga patu huakita whare, engari kāore he pānga o ētahi atu tikanga patu huakita ki te whai huatanga tātari o ngā mea kore-whatu rewa.

Ngā pānga o te whakamahana, te mamaoa me te mārama ultraviolet ki ngā āhuatanga tātari o ngā papanga kore-whatu rewa-pū

I rangahauhia hoki e ngā kairangahau ngā pānga o ngā tikanga whakahoromata maha ki ngā āhuatanga tātari o ngā mea kore-whatu rewa-pūhia, i hurihia e rātou mā te whakamahi i ngā pāmahana teitei, te mamaoa wai, me te hihi ultraviolet. I whakaatuhia e ngā hua i heke tere te whai huatanga tātari o ngā mea kore-whatu rewa-pūhia i muri i te 5 ngā wā o te maimoatanga huringa mamaoa wai, i te mea kāore i rerekē te mahi tātari o ngā mea kore-whatu rewa-pūhia i muri i te 10 ngā wā o te hihi pāmahana teitei me te hihi ultraviolet.

Te pānga o te mārama ultraviolet ki ngā āhuatanga o ngā papanga kore-whatu kua rewa

I rangahauhia anō ngā pānga o te haumākū me te pāmahana ki ngā āhuatanga tātari o ngā mea kore-whatu rewa. I whakaatuhia e ngā hua i te 85°C, i muri i te 20 wā o te maimoatanga i roto i ngā haumākū rerekē, kāore i tino heke te mahi tātari o ngā mea kore-whatu rewa, ā, kāore hoki i tino rerekē tōna hanganga. Ahakoa i muri i te 50 wā o te maimoatanga i te 85°C me te 30% haumākū, he iti noa te hekenga o te mahi tātari o ngā mea kore-whatu rewa. I taua wā anō, i whakamahia te maimoatanga kotahi ki te kopare N95, ā, kāore i tino heke tōna mahi tātari. Heoi anō, he rohe teitei o te 125℃ mō te pāmahana o te maimoatanga whakamahana, nā te mea pea kei te tata te pāmahana ki te pūwāhi rewa o te rauemi i tēnei wā, ā, ko te huringa o tōna hanganga iti ka arahi ki te hekenga o ngā hiko hiko.

Te panonitanga o te mahi tātari i muri i te whakamahana i te kakahu rehu rewa me te kopare i ngā pāmahana me ngā makuku rerekē

I runga i ngā whakatau o runga ake nei, e taunakihia ana kia kaua e whakamahia te waipiro, te patu huakita, te hopi me te wai hei horoi me te patu huakita i ngā kopare N95 i te wā e whakamahia anōtia ana. Ko te patu huakita ultraviolet me te patu huakita pāmahana teitei he tikanga patu huakita whiriwhiri. Heoi, nā te iti o te urunga o te hihi ultraviolet me te iti o te kaha patu huakita, he iti noa te pānga o te maimoatanga pāmahana teitei i raro i te 100°C ki ngā mea kore-whatu kua rewa, ā, ka taea te whakamahi anō mō ​​ngā wā maha. Nō reira, ko te maimoatanga pāmahana teitei i raro i te 100°C te tikanga patu huakita pai rawa atu mō ngā kopare N95.
