ʻO ka lole ulana ʻole/lole ulana ʻole, ma ke ʻano he mea ulana kuʻuna ʻole, he mea pono ʻole a koʻikoʻi hoʻi i ke kaiāulu hou ma muli o kona mau waiwai kū hoʻokahi a me nā ʻano hana like ʻole. Hoʻohana nui ia i nā ʻano kino a kemika paha e hoʻopaʻa a ulana i nā olonā, e hana ana i kahi lole me ka ikaika a me ka palupalu. Nui nā ʻano hana no nā lole ulana ʻole, a hāʻawi nā kaʻina hana like ʻole i nā lole ulana ʻole i nā ʻano like ʻole e hoʻokō ai i nā pono noi like ʻole.
Ma nā ʻoihana he nui e like me ke ola o kēlā me kēia lā, ka ʻoihana, a me ke kūkulu ʻana, hiki ke ʻike ʻia nā lole i ulana ʻole ʻia e pāʻani ana i kā lākou kuleana:
1. Ma ke kahua o ka mālama ola kino: nā pale maka, nā ʻaʻahu ʻoki kino, nā lole pale, nā ʻaʻahu lapaʻau, nā kāwele hoʻomaʻemaʻe, a pēlā aku.
2. Nā mea kānana: nā kānana ea, nā kānana wai, nā mea hoʻokaʻawale wai-ʻaila, a pēlā aku.
3. Nā mea hana Geotechnical: pūnaewele hoʻokahe wai, membrane anti-seepage, geotextile, a pēlā aku.
4. Nā mea komo lole: uhi lole, uhi, nā pale poʻohiwi, a pēlā aku.
5. Nā mea o ka hale: nā mea moe, nā uhi papaʻaina, nā pale, a pēlā aku.
6. ʻO loko o ke kaʻa: nā noho kaʻa, nā kaupaku, nā kāpeti, a pēlā aku.
7. Nā mea ʻē aʻe: nā mea hoʻopili, nā mea hoʻokaʻawale pila, nā mea hoʻokaʻawale huahana uila, a pēlā aku.
ʻO nā kaʻina hana nui o nā lole i ulana ʻole ʻia e komo pū me kēia:
1. Ke ʻano Meltblown: ʻO ke ʻano Meltblown kahi ʻano o ka hoʻoheheʻe ʻana i nā mea fiber thermoplastic, e pīpī ana iā lākou i ka wikiwiki kiʻekiʻe e hana i nā filaments maikaʻi, a laila e hoʻopaʻa pū iā lākou e hana i nā lole i ulana ʻole ʻia i ka wā o ke kaʻina hoʻomaʻalili.
-Kahe kaʻina hana: hānai polymer → extrusion heheʻe → hoʻokumu ʻana o ka fiber → hoʻoluʻu fiber → hoʻokumu pūnaewele → hoʻoikaika i loko o ka lole.
-Nā hiʻohiʻona: Nā olonā maikaʻi, hana kānana maikaʻi.
-Hoʻohana: Nā mea kānana kūpono, e like me nā pale maka a me nā mea kānana lapaʻau.
2. Ke ʻano Spunbond: ʻO ke ʻano Spunbond ke kaʻina hana o ka hoʻoheheʻe ʻana i nā mea fiber thermoplastic, e hana ana i nā fibers hoʻomau ma o ka hoʻolōʻihi wikiwiki ʻana, a laila e hoʻomaʻalili a hoʻopaʻa iā lākou i ka lewa e hana i ka lole i ulana ʻole ʻia.
-Kahe kaʻina hana: extrusion polymer → kīkoʻo e hana i nā filaments → waiho ʻana i loko o kahi mesh → hoʻopaʻa (hoʻopaʻa ponoʻī, hoʻopaʻa wela, hoʻopaʻa kemika, a i ʻole hoʻoikaika mechanical). Inā hoʻohana ʻia kahi wili poepoe e kau i ke kaomi, ʻike pinepine ʻia nā kiko kaomi wela maʻamau (pockmarks) ma ka ʻili lole i hoʻopaʻa ʻia.
-Nā Hiʻohiʻona: Nā waiwai mechanical maikaʻi a me ka hanu maikaʻi loa.
-Nā noi: nā lako lapaʻau, nā lole hoʻolei ʻia, nā mea hale, a pēlā aku.
Aia nā ʻokoʻa koʻikoʻi i ka microstructure ma waena o nā lole i ulana ʻole ʻia i hana ʻia e spunbond (hema) a me nā ʻano meltblown ma ka pae like. Ma ke ʻano spunbond, ʻoi aku ka nui o nā olonā a me nā hakahaka fiber ma mua o nā mea i hana ʻia e ke ʻano meltblown. ʻO ia ke kumu i koho ʻia ai nā lole i ulana ʻole ʻia meltblown me nā hakahaka fiber liʻiliʻi no nā lole i ulana ʻole ʻia i loko o nā masks.
