Ua ulu wikiwiki ke kī ʻeke ma muli o kona mau pono o ka "nui, hoʻomaʻemaʻe, maʻalahi, a me ka wikiwiki", a ke hōʻike nei ka mākeke kī ʻeke honua i kahi ʻano ulu wikiwiki.
Ma ke ʻano he mea hoʻopili no nā ʻeke kī,pepa kānana kīʻaʻole pono e hōʻoia wale i ka hiki i nā mea hana pono o ke kī ke hoʻolaha koke i loko o ka sopa kī i ka wā o ke kaʻina hana, akā pale pū i ka pauka kī i loko o ka ʻeke mai ke komo ʻana i loko o ka sopa kī. Ma hope o nā makahiki o ka hoʻomohala ʻana, ua neʻe mālie ka mea o ka pepa kānana kī mai ka gauze, ka pepa kānana, ka nylon, PET, PVC, PP a me nā mea ʻē aʻe i ka fiber kulina.
ʻO ka fiber kulina, i ʻike ʻia hoʻi ʻo ka fiber polylactic acid (PLA), ua loaʻa mai nā kumuwaiwai mea kanu hou e like me ka kulina, ka ʻuala, a me ka mauʻu mea kanu. Loaʻa iā ia ka biocompatibility maikaʻi a me ka biodegradability, nā waiwai antibacterial, a me ka breathability. ʻAʻole hiki ke hoʻohana wale ʻia e hana i nā ʻeke kī biodegradable non-woven, akā hoʻohana ʻia hoʻi i ke kahua hana pepa pulu e hana i ka pepa ʻōpala meaʻai e like me nā ʻeke kī, nā ʻeke kope, a mepepa kānana.
No laila, e kālele ana i nā ʻano hana o ka mea ponoʻī, he aha nā pono nui o ka hoʻohana ʻana i ka fiber PLA i ka hana pepa pulu?
1. He kūlohelohe ka mea a hiki ke hoʻopili me ka meaʻai
Loaʻa ka mea maka o ka fiber polylactic acid mai nā kumuwaiwai mea kanu hou. Ma ke ʻano he mea palekana meaʻai i hōʻoia ʻia, hiki ke hoʻohana nui ʻia ka fiber polylactic acid i nā ʻano meaʻai like ʻole, nā lāʻau lapaʻau, a me kekahi mau noi pepa home koi nui. ʻO ka lawe ʻana i ka hoʻohana ʻana i nā ʻeke kī a me ka pepa kānana kofe ma ke ʻano he laʻana, ʻoi aku ka maikaʻi o ke kau ʻana iā lākou i loko o ka wai wela me ka ʻole o ka ua ʻana o ka plastic a i ʻole nā mea ʻino ʻē aʻe.
2. Ka palaho ʻana o ka ʻiole
Ma ka hoʻohana ʻana i nā ʻeke kī ma ke ʻano he laʻana, nui ka nui o nā ʻeke kī hoʻolei ʻia e hoʻopau ʻia ma ka honua holoʻokoʻa i kēlā me kēia lā. ʻO nā ʻeke kī i hana ʻia mai nā mea kuʻuna he lōʻihi loa ka pōʻaiapuni degradation, kahi e lawe mai ai i ke kaomi nui i ka ʻōnaehana kūlohelohe. Eia nō naʻe, ʻo nā ʻeke kī a i ʻole nā huahana ʻē aʻe i hana ʻia mai nā mea polylactic acid he biodegradability maikaʻi loa.
Hiki ke hoʻoheheʻe piha ʻia nā huahana lole i ulana ʻole ʻia me ka fiber polylactic acid i ke kalapona ʻokikene a me ka wai e nā microorganisms i nā wahi kūlohelohe me kekahi mahana a me ka makū, e like me ke one, ka lepo, a me ka wai kai. Hiki ke hoʻoheheʻe piha ʻia nā ʻōpala huahana polylactic acid i ke kalapona ʻokikene a me ka wai ma lalo o nā kūlana composting ʻoihana (mahana 58 ℃, makū 98%, a me nā kūlana microbial) no 3-6 mau mahina; Hiki i ka hoʻopiha ʻāina ma nā wahi maʻamau ke hoʻokō i ka degradation i loko o 3-5 mau makahiki.
3. Hiki ke kāwili ʻia me ka pulp lāʻau a i ʻole nā lohi kūlohelohe ʻē aʻe no ka hoʻohana ʻana
Hoʻohui pinepine ʻia nā olonā waikawa polylactic i kahi ʻāpana me nā olonā pulp lāʻau, nā nanofibers, a me nā mea ʻē aʻe e hana i ka pulp a me ka pepa. He kuleana nui ka waikawa polylactic i ka hoʻopili ʻana a me ka hoʻoikaika ʻana, ma ka hoʻopili ʻana i nā olonā ʻē aʻe ma o ka wela a me ka mahana e hoʻokō ai i ke kumu o ka hoʻopili ʻana a me ka hoʻoikaika ʻana. Eia kekahi, ma ka hoʻoponopono ʻana i ka lakio slurry a me ke ʻano hana, hiki iā ia ke hoʻokō i nā pono like ʻole o nā kūlana like ʻole.
4. Hiki ke hoʻokō ʻia ka hoʻopaʻa wela ultrasonic
Ma ka hoʻohana ʻana i nā olonā polylactic acid e hana i ka pulp a me ka pepa, hiki ke hoʻokō ʻia ka hoʻopaʻa ʻana o ka ultrasonic thermal i ka hana ʻana ma hope, ʻaʻole ia e mālama wale i ka hana a hoʻemi i nā kumukūʻai, akā hoʻomaikaʻi pū i ka pono hana.
5. Hana kānana
ʻO ka pepa kānana kī i hana ʻia me ka fiber polylactic acid he hana kānana maikaʻi a me ka ikaika pulu kiʻekiʻe, hiki ke hoʻopaʻa pono i nā lau kī a me nā ʻāpana paʻa ʻē aʻe, ʻoiai e ʻae ana i ka ʻono a me ke ʻala o ke kī e komo piha.
Ma waho aʻe o ka pepa kānana kī, hiki ke hoʻohana ʻia ka fiber polylactic acid i ka pepa kānana ʻōpala lāʻau lapaʻau Kina kuʻuna, ka pepa kānana kofe, a me nā pepa ʻōpala meaʻai ʻē aʻe.
