ʻO ka lole i puhi ʻia i ka heheʻeʻo ia ka mea kānana koʻikoʻi o ka mask, ka mea i hoʻoholo nui ʻia e ke ʻano kānana o ka mea kānana pīpī hoʻoheheʻe ʻia, i māhele nui ʻia i ka pale mechanical, adsorption electrostatic a me ka mālama ʻana i ka electret.
1. Pale mīkini
Hiki ke like nā pale mīkini:
A. Hiki ke ālai ʻia nā kulu liʻiliʻi me ka nui o nā ʻāpana ma mua o 5um i ka lewa e nā mea kānana.
B. Ke emi ka anawaena o ka lepo ma mua o 3um, ua hoʻopaʻa ʻia ka lepo e ka papa fiber channel curved i loko o ka mea kānana mask.
C. Ke nui ka nui o ka ʻāpana a me ka wikiwiki o ke kahe ʻana o ke ea, ua hopu ʻia ka ʻāpana ma muli o ke kuʻi ʻana ma waena o ka inertia a me ka fiber; ke liʻiliʻi a haʻahaʻa ka wikiwiki o ka ʻāpana, ua hopu ʻia ka ʻāpana ma muli o ka neʻe ʻana o Brownian e hoʻopilikia ana i ka fiber.
2. Hoʻopili uila
ʻO ka maʻamau i ke kaʻina hana o ka lole pīpī hoʻoheheʻe ʻia e hana ʻia ka polar treatment, no laila ʻo ka lole i ulana ʻole ʻia me ka electrostatic hou aku, me ka adsorption electrostatic. ʻO ka adsorption electrostatic e pili ana i ka hopu ʻana i nā bacteria lepo a me nā virus ma o ka ikaika coulomb o ke fiber i hoʻopiʻi ʻia i ka wā e hoʻopiʻi ʻia ai ka fiber o ka mea kānana.
ʻElua mau ala e hoʻomaikaʻi ai i ka hiki ke mālama i nā uku o nā mea electret:
A. Ma ka hoʻomaikaʻi ʻana i ka crystallinity a me ka mechanical deformation o ka mea, e loli ke ʻano o ka mea a e hoʻokumu ʻia kahi kahawai lua lōʻihi a lahilahi e pale aku i ka drift charge.
B. Hoʻoulu i nā pahele uku e hopu i ka uku ma ka hoʻokomo ʻana i nā mea hoʻohui me nā waiwai mālama uku.
3. Ka hana ʻana i ke pou kū
ʻO ke kī i ka hoʻomaikaʻi ʻana i ka pono o ke kānana o nā pale maka e waiho ana i ka mālama electrostatic o nā lole i ulana ʻole ʻia i hoʻoheheʻe ʻia. Ma ke kahe o nā pale maka i kēia manawa, ʻaʻole lawa ka attenuation electrostatic (no ka laʻana, hapalua mahina ma hope o ko lākou haʻalele ʻana i ka hale hana). Eia nō naʻe, kūpono nā pale maka lapaʻau maʻamau no 6 mau mahina, ʻoiai kekahi mau pale maka Kepani e kūpono no 3 mau makahiki.
ʻO ka electret o ka lole nonwoven i puhi ʻia i ka heheʻe he mea maʻalahi loa ia i ka haʻahaʻa o ka ambient. Ua hana kekahi mea kūʻai aku i kahi hoʻokolohua. Ma hope o ka mālama ʻia ʻana no 7 mau lā ma lalo o ke kūlana o ka mahana maʻamau a me ke kiʻekiʻe o ka haʻahaʻa (ʻoi aku ka haʻahaʻa o ka pilina ma mua o 95%), ua hoʻemi ʻia ka hiki o ka ʻili o nā laʻana hoʻouka corona maikaʻi a maikaʻi ʻole i 28% a me 36% o ka waiwai mua. I kēia manawa ma muli o ka lole nonwoven i puhi ʻia i ka heheʻe he ʻano hāmama, ʻoi aku ka nui o ka ʻili kikoʻī, ʻoi aku ka pili ʻana me ke kaiapuni a puni, e hana i ka makū i ke kaiapuni, ke kinoea corrosive, nā ʻāpana i hoʻopiʻi ʻia e ka heterosexual, e like me ka ʻoi aku ka maʻalahi, i ka manawa like, hiki i ka ʻōnaehana hoʻouka corona ke hana i ka beam haʻahaʻa hiki ke hoʻouka ionic, ka hoʻouka ʻana i ka hoʻouka ʻana i ke kaʻina hana o ka hoʻouka ʻana i ka hapa nui o ka papa kokoke i ka ʻili i waiho ʻia ma nā fibers ʻili lole. Ke mālama ʻia a hana ʻia paha ka laʻana i kahi kaiapuni haʻahaʻa kiʻekiʻe, nui ka pohō o ka uku ma muli o ka hopena uku o nā hui polar i loko o nā molekala wai a me nā heteroions i ka lewa i ka hoʻouka ʻili kiʻekiʻe ma luna o ka fiber. No laila, pono e pale ʻia ke kaiapuni haʻahaʻa kiʻekiʻe i ke kaʻina hana o ka hoʻoheheʻe ʻana a me ka pīpī ʻana i ka lawe ʻana a me ka mālama ʻana i ka lole.
ʻO ka mea i luna aʻe ka nānā ʻana o nā kumu ʻekolu no kalole ulana ʻole i puhi ʻiae hōʻoia i ka pono o ka kānana. Manaʻolana wau e makemake ʻoe. He loea mākoumea hana ulana ʻole i puhi ʻia e hoʻoheheʻe ʻiaInā he mau koi kūʻai kāu, mai kānalua e hoʻokaʻaʻike koke mai iā mākou. E hoʻouna aku mākou i nā laʻana iā ʻoe me ka uku ʻole.
