Ua ulu wikiwiki ʻo Bagged kī ma muli o kāna mau pono o ka "nui, maʻemaʻe, ʻoluʻolu, a me ka wikiwiki", a ke hōʻike nei ka mākeke kī kī honua i kahi ulu wikiwiki.
Ma ke ʻano he mea hoʻopili no nā ʻeke kī,pepa kānana kīʻAʻole pono e hōʻoia i ka hiki koke ʻana o nā mea hana pono o ke kī i loko o ka sopa kī i ka wā o ke kaʻina hana brewing, akā e 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 hoʻololi mālie ʻia 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 corn.
ʻO ka pulupulu kulina, ʻike ʻia hoʻi ʻo ka polylactic acid (PLA) fiber, loaʻa ia mai nā kumuwaiwai mea kanu hou e like me ke kulina, uala, a me ka mauʻu hua. Loaʻa iā ia ka biocompatibility maikaʻi a me ka biodegradability, nā waiwai antibacterial, a me ka hanu. ʻAʻole hiki ke hoʻohana wale ʻia e hana i nā ʻeke kī kī ʻole biodegradable, akā ua hoʻopili pū ʻia i loko o ka māla pepa pepa e hana ai i ka pepa pepa meaʻai e like me nā ʻeke kī, ʻeke kope, apepa kānana.
No laila, e nānā ana i nā hiʻohiʻona hana o ka mea ponoʻī, he aha nā pōmaikaʻi nui o ka hoʻohana ʻana i ka fiber PLA i ka hana pepa pepa?
1. He kūlohelohe ka mea a hiki ke hoʻopili me ka meaʻai
ʻO ka mea maka o ka polylactic acid fiber e hele mai mai nā kumuwaiwai mea kanu hou. Ma ke ʻano he mea palekana meaʻai i hōʻoia ʻia, hiki ke hoʻohana nui ʻia ka polylactic acid fiber i nā ʻano meaʻai like ʻole, nā lāʻau lapaʻau, a me kekahi mau noi pepa hale koi nui. ʻO ka hoʻohana ʻana i nā ʻeke kī a me ka pepa kānana kope ma ke ʻano he laʻana, e hoʻokomo pololei iā lākou i loko o ka wai wela me ka ʻole o ka ua o ka plastic a i ʻole nā mea ʻino ʻē aʻe i ʻoi aku ka maikaʻi o ke kino kanaka.
2. Hiki i ka biodegradability
I ka lawe ʻana i ka hoʻohana ʻana i nā ʻeke kī ma ke ʻano he laʻana, nui ka nui o nā ʻeke kī i hoʻopau ʻia i ka honua i kēlā me kēia lā. ʻO nā ʻeke kī i hana ʻia mai nā mea kuʻuna, he pōʻai hoʻohaʻahaʻa lōʻihi loa ia, kahi e lawe mai ai i ke koʻikoʻi nui i ke kaiaola 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 hoʻopau loa ʻia nā huahana lole polylactic acid fiber non-woven fabric i carbon dioxide a me ka wai e nā microorganisms i nā wahi kūlohelohe me kekahi mau mahana a me ka haʻahaʻa, e like me ke one, ka lepo, a me ka wai kai. Hiki ke hoʻoheheʻe ʻia ka ʻōpala huahana polylactic i carbon dioxide a me ka wai ma lalo o nā kūlana composting ʻoihana (ka mahana 58 ℃, haʻahaʻa 98%, a me nā kūlana microbial) no 3-6 mahina; Hiki i ka hoʻopaʻa ʻāina i nā kaiapuni maʻamau ke hoʻokō i ka degradation i loko o 3-5 mau makahiki.
3. Hiki ke hoʻohuiʻia me ka pulp lāʻau a iʻole nā mea'ē aʻe maoli no ka hoʻohana
Hoʻohui pinepine ʻia nā fibers polylactic acid i kekahi ʻāpana me nā fiber pulp lāʻau, nanofibers, etc. e hana i ka pulp a me ka pepa. ʻO ka polylactic acid ka mea nui i ka hoʻopaʻa ʻana a me ka hoʻoikaika ʻana, ma ka hoʻopili ʻana i nā fibers 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 ratio slurry a me ke ʻano hana, hiki iā ia ke hoʻokō i nā pono like ʻole o nā hiʻohiʻona like ʻole.
4. Hiki ke hoʻokō ʻia ka hoʻopaʻa ʻana o ka ultrasonic thermal
Ma ka hoʻohana ʻana i nā fibers polylactic acid e hana i ka pulp a me ka pepa, hiki ke hoʻokō ʻia ka hoʻopaʻa ʻana o ka thermal ultrasonic i ka hana ma hope, ʻaʻole ia e mālama wale i ka hana a hoʻemi i nā kumukūʻai, akā hoʻomaikaʻi pū i ka hana pono.
5. Hana kānana
ʻO ka pepa kānana kī i hana ʻia me ka polylactic acid fiber he hana kānana maikaʻi a me ka ikaika pulu kiʻekiʻe, hiki ke mālama pono i nā lau kī a me nā mea paʻa ʻē aʻe, ʻoiai e ʻae i ka ʻono a me ka ʻala o ke kī e komo piha.
Ma waho aʻe o ka pepa kānana kī, hiki ke hoʻohana ʻia ka polylactic acid fiber i ka pepa kānana lāʻau lapaʻau kuʻuna Kina, pepa kānana kope, a me nā pepa ʻai meaʻai ʻē aʻe.
