ʻO ka Poly Lactic Acid kahi polymer i loaʻa ma ka polymerizing lactic acid ma ke ʻano he kumu kumu a he ʻano hou o nā mea biodegradable.No laila,PLA wilihe wili pili kaiapuni.
Aia ke kumu o ka PLA ka mea paʻi 3D kaulana loa a hoʻohana nui ʻia no nā mea paʻi FDM.Ke hoʻohālikelike ʻia me nā mea ʻē aʻe, he maʻalahi loa ka paʻi ʻana, a he filament kūpono no nā amateurs.Pēlā nō, manaʻo nui ʻia kēlāfilament PLAʻoi aku ka paʻa a me ka palekana ma mua o nā mea ʻē aʻe.No hea mai kēia manaʻo?He aha i ka hoʻomau o100% PLA pili kaiapuni?A laila e kālele mākou i nā pilikia e pili ana iā PLA.
1. Pehea ka hana ʻana o PLA?
ʻO ka PLA, ka mea i kapa ʻia ʻo Poly Lactic Acid, loaʻa mai nā mea kūlohelohe maoli e like me ke kulina.Wehe i ka starch (glucose) mai nā mea kanu a hoʻololi iā ia i glucose ma ka hoʻohui ʻana i nā enzymes.Hoʻomoʻa nā microorganism iā ia i ka waikawa lactic, a laila hoʻololi ʻia i polylactide.Hoʻopuka ka Polymerization i nā kaulahao molekala lōʻihi nona nā waiwai like me nā polymers i hoʻokumu ʻia i ka ʻaila.
2. He aha ka manaʻo o "PLA's biodegradable and compostable"?
ʻO nā huaʻōlelo "biodegradable and compostable" a me ko lākou ʻokoʻa he mea koʻikoʻi a hoʻomaopopo pinepine ʻia.Ua wehewehe ʻo Jan-Peter Willie: "He nui ka poʻe e huikau i ka "biodegradable" me ka "compostable."Ma ka ʻōlelo ākea, ʻo ka "biodegradable" ʻo ia ka mea hiki ke biodegraded kahi mea, ʻoiai ʻo "Compostable" ʻo ia ka mea maʻamau e hopena kēia kaʻina i ka compost.
Ma lalo o kekahi mau kūlana anaerobic a i ʻole aerobic, hiki ke hoʻoheheʻe ʻia nā mea "biodegradable".Eia naʻe, aneane pau nā mea āpau e decompose me ka hele ʻana o ka manawa.No laila, pono e wehewehe pono ʻia nā kūlana kūlohelohe i biodegradable.ʻO ka hana compost he hana hana.Wahi a ka European standard EN13432, inā i loko o ʻeono mau mahina i loko o kahi mea kanu composting ʻoihana, ʻoi aku ka liʻiliʻi o 90% o ka polymer a i ʻole ka pahu i hoʻololi ʻia i carbon emissions e nā microorganisms, a ʻo ka nui o ka mea hoʻohui ʻia he 1%, ʻo ka polymer a i ʻole ka pahu. i manaʻo ʻia he "compostable".ʻAʻole pōʻino ka maikaʻi kumu.A i ʻole hiki iā mākou ke ʻōlelo ma kahi pōkole: "He biodegradable nā mea kanu a pau, akā ʻaʻole nā mea hoʻoheheʻe ʻia a pau he compost".
3. He ʻoluʻolu maoli anei ka wili PLA?
I ka hoʻolaha ʻana i nā mea PLA, hoʻohana pinepine ʻia ka huaʻōlelo "biodegradable", e hōʻike ana i ka PLA, e like me ka ʻōpala kīhini, hiki ke pala i loko o ka compost hale a i ʻole ka honua kūlohelohe.Eia naʻe, ʻaʻole kēia ka hihia.Hiki ke wehewehe ʻia ke filament PLAfilament PLA hiki ke hoʻohaʻahaʻa maoli ʻia, akā, ma lalo o nā kūlana kiko'ī o ka hoʻoheheʻe ʻana i ka ʻoihana, i kēia hihia, ʻoi aku ka maikaʻi o ka ʻōlelo ʻana he polymer biodegradable.ʻO nā kūlana hoʻopuehu ʻoihana, ʻo ia hoʻi i mua o nā microorganisms, ʻo ka mālama ʻana i ka mahana a me ka haʻahaʻa he kūlana kūpono ia no ka PLA e hoʻohaʻahaʻa maoli ʻia.Ua wehewehe ʻo Florent Port.Ua hoʻohui ʻo Jan-Peter Willie: "He compostable ka PLA, akā hiki ke hoʻohana wale ʻia i nā mea kanu compost ʻoihana."
Ma lalo o kēia mau ʻano hana composting, hiki ke biodegraded ʻo PLA i loko o nā lā a i nā mahina.Pono ke kiʻekiʻe o ka mahana ma mua o 55-70ºC.Ua hōʻoia pū ʻo Nicholas: "Hiki ke biodegraded ka PLA ma lalo o nā kūlana composting ʻoihana."
4. Hiki ke hana hou ia PLA?
Wahi a nā loea ʻekolu, hiki ke hana hou ʻia ʻo PLA ponoʻī.Eia naʻe, kuhikuhi ʻo Florent Port: “ʻAʻohe ohi ʻōpala PLA kūhelu no ka paʻi 3D.ʻO ka ʻoiaʻiʻo, paʻakikī ke ʻano o ka ʻōpala palaka i kēia manawa e hoʻokaʻawale i ka PLA mai nā polymers ʻē aʻe (e like me PET (nā hue wai)". .”
5. ʻO ka filament kulina PLA ka filament maikaʻi loa?
Manaʻo ʻo Nicolas Roux ʻaʻohe ʻano ʻē aʻe e hoʻomau i ka filament kulina, "ʻO ka mea pōʻino, ʻaʻole wau i ʻike i ka filament kulina ʻōmaʻomaʻo a palekana, inā paha e hoʻokuʻu lākou i nā ʻāpana i ka honua a i ʻole ka moana a i ʻole hiki ke biodegrade iā lākou iho.Manaʻo wau i ke koho ʻana i nā mea, makemake nā mea hana e hoʻohana i nā filament me ka palekana kūpono ma ke ʻano kūpono.
ko Jiayi100% biodegradable wili PLAua lanakila i ka mahalo lokahi ma waena o nā mea kūʻai.Inā ʻoe e ʻimi nei i kahi wili emvronmentally friendly kūpono, hiki iā ʻoe ke hoʻokaʻaʻike mai iā mākou
