Ka huna i te uho o tekakahu rewaHe mea hanga te rauemi tātari ki te muka polypropylene tino pai me te tohatoha matapōkere. Ko te āhua, he maeneene, he ngawari, he mā te kiko o te muka mai i te 0.5 ki te 1.0 mu m. Mā te tohatoha matapōkere o te muka ka nui ake ngā whai wāhitanga mō te hononga wera i waenga i te muka, ā, ka nui ake te horahanga mata motuhake o te rauemi tātari hau rewa-puia, ka nui ake te porosity (75%), ka teitei ake rānei. Mā te pai o te tātari o te taputapu tātari ngaohiko teitei, he iti te ātete, he nui te pai me te kaha puehu teitei.
Te uho o te kopare
Ko te papanga kore-whatu rewa-pūhia hei momo rauemi tātari tino whai hua ko ngā kopare "ngākau", ki te whakataurite ki te rauemi tātari tuku iho, kua piki ake te pai o te tātari hau me te purenga ki te kotahi rau ngā wā, inaianei ko te mea tino pai mō ngā rauemi tiaki hauora koiora (ka taea te whakamahi i te waro whakahohe me ngā rauemi rite mō ngā matū tiaki, ki ngā huakita me ngā huaketo me te kore mahi purenga tātari). I tōna whānautanga ohorere i te pō kotahi, ka WHAKAMAHI te umanga hauora i te rau tau o te kopare miro kua whakakorea katoatia. Ko te tiaki hauora e wehea ana kia toru ngā taumata e ai ki te taumata o ngā whakaritenga tiaki. Ko ngā "kopare pokanga" kikorangi mārama e mau ana tātou i te nuinga o te wā ka taea te whakamahi hei tiaki tuatahi, ko te nuinga ki te tuku kino o ngā pata kei roto ngā pathogens i roto i te oranga o ia rā me te hanga. Ko te mahi matua hei whakapai ake i te kaha tiaki ko te tāpiri i tētahi paparanga tātari i hangaia ki te kakahu kore-whatu kua rehuhia ki te rewa ki waenganui o te kopare.
Ko te paparanga tiaki i waenganui o te kopare (paparanga M te poto) he kakahu kore-whatu polypropylene kua rehuhia ki te rewa, ā, ko ngā taha o mua me muri o te kopare he paparanga miro-hono (paparanga S te poto). I runga i te taumata tiaki e hiahiatia ana, ka taea te whakanoho i tētahi paparanga ki roto i te paparanga M. Mena he kopare tiaki taumata 1, whakamahia he paparanga M. Mō te manawa rehu taumata 3 pēnei i te N95, me toru, neke atu rānei ngā paparanga kakahu kore-whatu kua rehuhia ki te rewa mō te paparanga-M. Ko te tikanga, ko te maha o ngā paparanga o te paparanga M, ko te kino o te uruhanga hau o te kopare, ka rerekē ngā hua motuhake.
Ki te haehaea e tātou tētahi kopare, ka kitea ngā paparanga e toru i runga ake nei, arā, te paparanga waikore, te paparanga tātari matua, me te paparanga ārai wai.
Kei waenganui o te paparanga tātari kopare te kakahu rehu rewa, ka taea te tātari i ngā huakita, te ārai i te horapa o ngā iroriki. I roto i te kakahu rehu rewa, ko te kakahu rehu rewa te nuinga ki te polypropylene hei rauemi mata matua, ka taea te tae ki te diameter muka ki te 1 ~ 5 micron. Ka whakanuia e ēnei muka tino pai me te hanganga capillarity ahurei te maha me te horahanga mata o ngā muka i ia wāhanga horahanga, kia pai ai te tātari, te tiaki, te whakamarumaru me ngā āhuatanga mimiti hinu o te kakahu rehu rewa. Ka taea te whakamahi i roto i te hau, i ngā rauemi tātari wai, i ngā rauemi wehe, i ngā rauemi mimiti, i ngā rauemi kopare, i ngā rauemi whakamahana, i ngā rauemi mimiti hinu me te kakahu muru me ētahi atu mara.
Te hopu me te mimiti
He momo polypropylene te papanga rewa-pūwero, he teitei te taupū rewa, he mea hanga mai i ngā muka maha e whakawhiti-whiti ana, he mea whakakikorua ki tētahi ahunga matapōkere. Ko te whānui o ngā muka kei waenga i te 0.5 ki te 10 maikorona, ā, ko te whānui o ngā muka he tata ki te kotahi hautoru o te makawe.
E kitea ana i te pikitia, he maha tonu ngā āputa i roto i te kopare i raro i te karu hikohiko. Nā, me pēhea te ārai i te huaketo?
Ngā koparete tiaki i a koe mai i ngā huaketo mā te mahi i ngā mea e rua: te hopu me te hopu
Te hopu:
Ka whakawhirinaki te rauemi tātari ki ngā tukanga kakahu, ki ngā tukanga kore-whatu rānei, hei whakatutuki i te matotoru o ngā muka i roto i te wāhi, hei hanga i tētahi whatunga o ngā pūwero, ā, ka hanga he pānga "ārai" ki te hau e rere ana. Ka "āraihia" ngā matūriki nunui i te hau e te tukinga ki ngā muka, e te mata muka rānei e ārai ana i te taha o te rauemi tātari. Mō ngā matūriki kore-koiora i te hau (pēnei i te puehu, te PM2.5, me ētahi atu), ko te whai huatanga o te purenga o ngā kopare e whakawhirinaki ana ki te kaha kotahi o te ārai o ngā rauemi tātari.
Te mimiti:
Mō ngā kopare tiaki koiora, nā te iti rawa o te rahi tinana o ngā mate pāwera pēnei i ngā huaketo, he uaua ki te pure i te nuinga o ngā matū kino mā te hopu i ngā āputa muka kopare. Nō reira, kua noho te mimiti hiko hei āhuatanga matua o te mahi tiaki kopare. He ngoikore rawa ngā muka taiao tuku iho ki te whakaputa me te kawe i te hiko hiko, nō reira he iti noa te pānga mimiti o ngā kopare kākahu. Ā, he rauemi pai te muka whakarewa polymer kore-polar mō te whakaputa me te pupuri hiko (i tēnei wā, ka taea e koe te whakarite i te ahua o te mau kākahu miro parakore me ngā kākahu muka matū), kia "tūturu" ai te mahi mimiti. He nui ngā mahi a ngā kairangahau ki te whakaputa me te pupuri i te pai o te hiko hiko o ngā rauemi tātari. I roto i te hanga kopare, ka whakamahia ngā tikanga miihini, hiko rānei hei whakarei ake i te utu hiko hiko ki roto i ngā rauemi rehu rewa.
Nā te kaha ahurei o te mimiti hiko, ka taea e te hangarau rehu rewa te whakaputa muka matū he iti ake te diameter i te muka taiao, he pai hoki mō te whakaputa i te mimiti matū. Ko te papanga kore-whatu i rehuhia ki te polypropylene te mea tuatahi hei whiriwhiri mā ngā rauemi kopare tiaki hauora.
