No ka ʻōlelo ʻana he nui nā ʻano mea ʻeke kī, ʻo nā mea ʻeke kī maʻamau ma ka mākeke ʻo ka pulupulu kulina, ʻaʻole i ulana ʻia pp mea, non-woven mea holoholona a me kāna pepa kānana.
ʻEke kī pepa i inu ʻia e ka poʻe Pelekania i kēlā me kēia lā. He aha ke ʻano o ka ʻeke kī maikaʻi? Aia ma lalo kahi hoʻolauna i kēia ʻano ʻeke kī.
1. ʻeke kī kīʻaha kānana
ʻO ka pulupulu kānana he fiber synthetic i hana ʻia mai ke kulina, ka palaoa a me nā starch ʻē aʻe e like me nā mea maka, i hana kūikawā ʻia i lactic acid a laila polymerized a milo. He fiber ia e hoʻopiha ai i ke kaiapuni kūlohelohe a hiki ke hoʻoheheʻe ʻia. ʻAʻole hoʻohana ka fiber i ka ʻaila a me nā mea ʻē aʻe kemika, a hiki ke hoʻoheheʻe ʻia kona ʻōpala i carbon dioxide a me ka wai ma lalo o ka hana a nā microorganism i ka lepo a me ka wai kai, ʻaʻole ia e hoʻohaumia i ka honua honua.
2. Non-woven pp mea kī eke
ʻO ka mea pp he polypropylene, ʻo ia ka polymer keʻokeʻo keʻokeʻo keʻokeʻo ʻaʻole i ʻoki ʻia, ʻaʻala ʻole, a ʻono ʻole. ʻO ka polyester PP kahi ʻano amorphous, ʻoi aku kona helu hoʻoheheʻe ma luna o 220, a ʻo kona ʻano wela e pili ana i 121 degere. Akā, no ka mea, he macromolecular polymer ma hope o nā mea a pau, ʻoi aku ka kiʻekiʻe o ka mahana, ʻoi aku ka liʻiliʻi o ka nānā ʻana
ʻOi aku ka nui o nā oligomers, a ʻaʻole maikaʻi ka hapa nui o kēia mau mea no ke olakino kanaka. Eia kekahi, e like me ka hoʻohana ʻana o ka mea kūʻai aku, ʻo ka wai paila ka maʻamau 100 degere, no laila ʻaʻole e hōʻailona ʻia nā kīʻaha plastik maʻamau ma mua o 100 degere.
3. Non-woven holoholona holoholona kīʻeke
Ma ke ʻano he mea hoʻopili, ʻoi aku ka maikaʻi o ka PET kiʻekiʻe a haʻahaʻa. Hiki ke hoʻohana ʻia no ka manawa lōʻihi i ka pae wela o 120 degere, a hiki iā ia ke kū i ka wela kiʻekiʻe o 150 degere no ka hoʻohana pōkole. He haʻahaʻa ka permeability o ke kinoea a me ka mahu wai, a loaʻa iā ia ka maikaʻi o ke kinoea, ka wai, ka aila a me ke ʻano ʻala. ʻO ke aniani kiʻekiʻe a me ka nani maikaʻi. ʻAʻohe mea ʻawaʻawa, ʻono ʻole, a maikaʻi ka maʻemaʻe a me ka palekana, a hiki ke hoʻohana pololei ʻia i ka meaʻai.
4. Nā ʻeke kī i hana ʻia me ka pepa kānana
Ma waho aʻe o ka pepa kānana i hoʻohana ʻia i loko o nā laboratories maʻamau, nui nā noi o ka pepa kānana i ke ola o kēlā me kēia lā, a ʻo ka pepa kānana kope kekahi o lākou. Hāʻawi ka pepa kānana ma ka papa waho o ka ʻeke kī i ka palupalu kiʻekiʻe a me ka ikaika pulu. Hana ʻia ka hapa nui o nā pepa kānana me nā pulupulu pulupulu, a he nui nā puka liʻiliʻi ma luna o kona ʻili no nā ʻāpana wai e hele ai, ʻoiai ʻaʻole i ʻōlelo ʻia nā ʻāpana paʻa nui.
5. ʻeke kī pepa
ʻO kekahi o nā mea maka i hoʻohana ʻia i loko o kēia ʻeke kī pepa ʻo ka abaca. He lahilahi kēia mea a he loloa kona. He ikaika a porous ka pepa i hana ʻia, e hana ana i nā kūlana kūpono no ka laha ʻana o ka ʻono kī. ʻO nā mea maka ʻē aʻe he pulupulu hoʻopaʻa wela, kahi e hoʻopaʻa ai i ka ʻeke kī. ʻAʻole hoʻomaka kēia plastik e hoʻoheheʻe a hiki i ka wela i 160 ° C, no laila ʻaʻole maʻalahi ka hoʻopuehu ʻana i ka wai. I mea e pale ai i ka ʻeke kī ponoʻī mai ka hoʻoheheʻe ʻana i ka wai, ua hoʻohui pū ʻia kahi mea kolu, ʻo ka pulp lāʻau. Ma hope o ka hoʻokahe ʻia ʻana o ka hui ʻana o ka abaca a me ka plastik, ua uhi ʻia me kahi papa o ka pulp lāʻau, a hoʻokomo ʻia i loko o kahi mīkini pepa nui 40 mika ka lōʻihi, a hānau ʻia ka pepa kī.
