He aha ka PLA?Nā mea a pau e pono ai ʻoe e ʻike
Ke ʻimi nei ʻoe i kahi mea ʻē aʻe i ka plastic a me ka hoʻopili ʻana i ka ʻaila?Ke neʻe nui nei ka mākeke o kēia lā i nā huahana biodegradable a me nā huahana eco-friendly i hana ʻia mai nā kumuwaiwai hou.
PLA kiʻiʻoniʻoniua lilo koke nā huahana i hoʻokahi o nā koho biodegradable kaulana loa ma ka mākeke.Ua ʻike ʻia kahi noiʻi 2017 ʻo ka hoʻololi ʻana i nā plastics-based petroleum me nā plastics-based bio-based hiki ke hōʻemi i ka hoʻokuʻu ʻia ʻana o ke kinoea hoʻomehana honua ma 25%.
He aha ka PLA?
ʻO ka PLA, a i ʻole polylactic acid, ua hana ʻia mai kekahi kōpaʻa fermentable.Hana ʻia ka hapa nui o ka PLA mai ke kulina no ka mea ʻo ka kulina kekahi o nā mea koʻikoʻi loa a loaʻa loa i ka honua.Eia nō naʻe, ʻo ke kō, ke aʻa tapioka, ka ʻuʻuku, a me ka pulp sugar beet kekahi mau koho ʻē aʻe.
E like me ka nui o nā mea pili i ke kemika, paʻakikī loa ke kaʻina hana o ka hana ʻana i ka PLA mai ka kulina.Eia nō naʻe, hiki ke wehewehe ʻia i kekahi mau ala pololei.
Pehea e hana ʻia ai nā huahana PLA?
ʻO nā ʻanuʻu kumu e hana ai i ka polylactic acid mai ka kulina penei:
1. Pono e ho'ololi 'ia ka mākiko kulina mua i kō ma o ke ka'ina hana i kapa 'ia ka wili pulu.ʻO ka wili pulu e hoʻokaʻawale i ka starch mai nā kernels.Hoʻohui ʻia ka ʻakika a i ʻole nā enzyme ke hoʻokaʻawale ʻia kēia mau ʻāpana.A laila, hoʻomehana ʻia lākou e hoʻololi i ka mākiko i dextrose (aka sugar).
2. A laila, ua fermented ka dextrose.ʻO kekahi o nā hana fermentation maʻamau e pili ana i ka hoʻohui ʻana i ka bacteria Lactobacillus i ka dextrose.ʻO kēia ka mea e hana ai i ka lactic acid.
3. A laila, hoʻololi ʻia ka ʻakika lactic i lactide, he dimer ʻano apo o ka waikawa lactic.Hoʻopili pū kēia mau molekala lactide e hana i nā polymers.
4. ʻO ka hopena o ka polymerization he mau ʻāpana liʻiliʻi o ka polylactic acid plastic maka i hiki ke hoʻololi ʻia i kahi ʻano o nā huahana plastik PLA.
He aha nā pōmaikaʻi o nā huahana PLA?
Pono ʻo PLA i ka 65% emi mai ka ikehu e hana ai ma mua o ka mea kahiko, ka ʻaila.He 68% ka liʻiliʻi o nā kinoea hoʻomehana honua.ʻAʻole ʻo ia wale nō:
Nā pōmaikaʻi o ke kaiapuni:
Hoʻohālikelike ʻia me nā plastic plastics - ʻoi aku ma mua o 95% o nā plastics o ka honua i hana ʻia mai ke kinoea maoli a i ʻole ka aila ʻaila.ʻAʻole pōʻino wale nō nā plastics i hoʻokumu ʻia i ka wahie fossil;he waiwai palena ʻole lākou.Hōʻike nā huahana PLA i kahi mea hana, hiki ke hoʻololi a hoʻohālikelike.
Bio-based– Loaʻa nā mea waiwai o kahi huahana bio-based mai ka mahiʻai hou a mea kanu paha.No ka loaʻa ʻana mai o nā huahana PLA a pau mai nā kōpaʻa kōpaʻa, manaʻo ʻia ka polylactic acid i ka bio-based.
Biodegradable- Loaʻa nā huahana PLA i nā kūlana honua no ka biodegradation, hoʻohaʻahaʻa maoli ma mua o ka hōʻiliʻili ʻana i nā ʻāina.Pono ia i kekahi mau kūlana e hoʻohaʻahaʻa koke.I loko o kahi hale hoʻopuehu ʻoihana, hiki iā ia ke wāwahi i nā lā 45-90.
ʻAʻole hoʻokuʻu i ka uahi ʻawaʻawa – ʻAʻole like me nā plastics ʻē aʻe, ʻaʻole hoʻopuka nā bioplastics i nā uahi ʻona ke puhi ʻia.
Thermoplastic– He thermoplastic ka PLA, no laila hiki ke hoʻoheheʻe ʻia a malleable ke hoʻomehana ʻia a hiki i kona wela heheʻe.Hiki ke hoʻopaʻa ʻia a hoʻoheheʻe ʻia i loko o nā ʻano like ʻole e lilo ia i mea koho maikaʻi loa no ka hoʻopili meaʻai a me ka paʻi 3D.
Food Contact-aponoia- Ua ʻae ʻia ka polylactic acid ma ke ʻano he polymer Generally Recognized as Safe (GRAS) a palekana no ka pili ʻana i ka meaʻai.
Nā pōmaikaʻi o ka ʻeke meaʻai:
ʻAʻole like ko lākou ʻano hoʻohui kemika ʻino e like me nā huahana kumu ʻaila
E like me ka ikaika e like me nā plastics maʻamau
Palekana-palekana
Hiki i nā kīʻaha ke mālama i nā mahana a hiki i 110°F (hiki i nā mea PLA ke mālama i nā mahana a hiki i 200°F)
Non-toxic, carbon-neutral, a 100% hiki ke hoʻololi hou
I ka wā ma mua, i ka wā i makemake ai ka poʻe lawelawe meaʻai e hoʻololi i ka ʻeke eco-friendly, loaʻa paha iā lākou nā huahana pipiʻi a subpar wale nō.Akā ʻo ka PLA he hana, kūpono ke kumu kūʻai, a hoʻomau.ʻO ka hoʻololi ʻana i kēia mau huahana he hana koʻikoʻi ia i ka hōʻemi ʻana i ka wāwae kalapona o kāu ʻoihana meaʻai.
Ma waho aʻe o ka ʻeke meaʻai, he aha nā mea hoʻohana ʻē aʻe no PLA?
I ka wā i hana mua ʻia ai, kūʻai ʻo PLA ma kahi o $200 e hana ai i hoʻokahi paona.Mahalo i nā hana hou i nā kaʻina hana, ʻoi aku ka liʻiliʻi ma mua o $ 1 no ka paona e hana i kēia lā.No ka mea ʻaʻole ia he kumu kūʻai, hiki i ka polylactic acid ke hoʻohana nui.
ʻO nā mea hoʻohana maʻamau ka:
3D mea paʻi filament
Hoʻopili meaʻai
Puke lole
Hoʻopili ʻana
Ma kēia mau noi āpau, hōʻike nā koho PLA i nā mea maikaʻi ma mua o nā mea kuʻuna.
No ka laʻana, ma nā mea paʻi 3D, ʻo nā filament PLA kekahi o nā koho kaulana loa.He haʻahaʻa ko lākou wahi heheʻe ma mua o nā koho filament ʻē aʻe, e maʻalahi a palekana hoʻi e hoʻohana.Hoʻopuka ka filament PLA 3D i ka lactide, ka mea i manaʻo ʻia he ʻawaʻawa ʻole.No laila, ʻaʻole like me nā koho filament, paʻi ʻo ia me ka ʻole o ka hoʻokuʻu ʻana i nā toxins ʻino.
Hāʻawi pū ia i kekahi mau mea maikaʻi ma ka ʻoihana lapaʻau.Makemake ʻia ʻo ia ma muli o kona biocompatibility a me ka hoʻohaʻahaʻa palekana e like me ka hoʻohaʻahaʻa ʻana o nā huahana PLA i lactic acid.Hoʻopuka maoli ko mākou kino i ka waika lactic, no laila he pūhui kūpono.Ma muli o kēia, hoʻohana pinepine ʻia ʻo PLA i nā ʻōnaehana hoʻopuka lāʻau, nā implants lapaʻau, a me ka ʻenekinia kiko.
I ka honua fiber a me textile, manaʻo ka poʻe kākoʻo e hoʻololi i nā polyesters nonrenewable me ka fiber PLA.ʻO nā lole a me nā lole i hana ʻia me ka fiber PLA he māmā, hanu, a hiki ke hana hou.
Hoʻohana nui ʻia ʻo PLA i ka ʻoihana pale.Ua hoʻomaka nā hui nui e like me Walmart, Newman's Own Organics a me Wild Oats i ka hoʻohana ʻana i ka ʻōpala compostable no nā kumu kaiapuni.
Ua kūpono nā huahana PLA no kaʻu ʻoihana?
Inā hoʻohana kāu ʻoihana i kekahi o kēia mau mea a makemake ʻoe i ka hoʻomau ʻana a me ka hoʻohaʻahaʻa ʻana i ka wāwae kalapona o kāu ʻoihana, a laila he koho maikaʻi loa ʻo PLA packaging:
Nā kīʻaha (nā kīʻaha anuanu)
Nā pahu Deli
Puke pohū
Mea ʻai meaʻai
mauʻuʻu
ʻeke kope
No ka ʻike hou aku e pili ana i nā huahana PLA kūpono a me ka pili o ke kaiapuni o YITO Packaging, e kelepona mai!
