REVODE101 ua, ua hoʻokō 'ia e maloʻo ana crystallization, ma hope a, ka mea kiʻekiʻe loa wela kumupaʻa o ke kēpau, he 110 ℃, a me ka ona mau maʻiʻo mea emi o 200 ppm. Ke kēpau e waiho ma ka Aluminum pepa kiniʻeke, hoomaluia ma ka pahu a eke mawaho hiki ke hoʻohana 'ana. Re-ka maloʻoʻana o ka kēpau hiki e ka ona mau maʻiʻo malalo o 100 ppm, i mea maikaʻi, e hōʻoi 'i ka processability o ke kēpau, a me ka mea e like ai o ka pepa.
I ka hou-maloʻo ana i ka kēpau, ka un-dehumidified wela ea ua papaia, no ka ole dehumidifier,ʻaʻole wale nō ka ka maloʻoʻana kanawai hiki ole ke loaa, akā, i hiki e hōʻeleu i ka mämä holo o ka wai absorbance o PLA kēpau. Na dehumidified ea ke kumu hoʻomalu i ka ka maloʻoʻana kanawai o PLA kēpau ma ka desiccator.
? Aaei PLA ka maloʻoʻana hana hea hōʻike i loko o ka papaʻaina kēia:

Pāhana mea hiki ke hoʻohana hou 'ia (i ka pāhana pono hana e ia mai hou ma mua o 3 mahina, a me ka ole oi aku mamua o 35% ma ka eiiieaena). Mamuli no ke koi i ka ona mau maʻiʻo o ka pepa extrusion E e haʻahaʻa ma mua o 200 ppm, pono e hana mai ai i nā pāhana mea me ka crystallization a me kiʻekiʻe-wela ka maloʻoʻana ma ka desiccant noonoo.
Crystallization hana 1:
General crystallization lako a pan no Ka Hānai Ā Huhu, ua maikaʻi nō. No ka laʻana, ka wā 0.5 m3 crystallization autoclave ua wae, na pono hana e e hui homogeneously, me ka 1: 1 kaumaha lākiō o ka pāhana mea i maemae PLA. Ma hope o ua i hoʻohuiʻia i loko o ka crystallization autoclave, ka hoʻomehana crystallization o ka luna 'ka hoʻomaka' ana ma lalo o hoʻohuihui i ka mämä holo o ka 3 rpm. Ka wela Ua hoonoho i 60 ℃ no 20min, 80 ℃ no 10 min, 95 ℃ no ka 10min, ma hope ma 110 ℃ no 30 min, a laila, uwo ana wela ka anu u ma ka anu u. Ka a pau crystallization kaʻina mau no ma kahi o 1.5 hora.
Crystallization hana 2:
Ma ka hoʻohana 'ana i ka Kreyenborg welaʻula crystallization pono, ua enaena, na mea ma ka welaʻula, pu ma ke kuapo paʻipaʻiʻia ai ma hope o ka i hoʻohuiʻia i loko o ka welaʻula crystallization ape barela. Ka makaʻu o keia iaoia mea i ka crystallization a me ka maloʻoʻana kaʻina e lawe mai i ka ia manawa, a me ke kaʻina hiki e pau ai i loko o 15 ~ 20 min.
Crystallization hana 3:
Ma hope o ua mālama '-maloo ma haʻahaʻa-ana wela, i ka pāhana pono hana e e extruded a me palletized, ma hope o laila, o ka crystallization kaʻina hana hiki ke hana ia ma Ka Hānai Ā Huhu crystallization lako a pan.

Ōlelo Aʻo:'āpana a me nā'āpana hiki ke hoʻohana hou 'ia no kekahi mau manawa. Iloko o ka hoʻohana hou 'ana kaʻina hana o ka pāhana mea, he uuku nui o ka Hope Agena - ADR hiki e hou, e emi i ka waiwai emi o ka pāhana mea pono, a me ka paipai dala mea 0,1 ~ 0,6%.

Compost hoʻololi iho
ka PLA ke hoʻokō piha biodegradation i loko o 180 mau lā ma lalo o compost hoʻololi iho rula, a me ka mea hope loa huahana i carbon dioxide i a me ka wai. Ke composting kumu e like penei:
○ Ka Mahana He 58 ± 2 ° C
○ Humidity He 98%
○ Aia i kekahi microorganisms

Landfill hoʻololi iho
ka landfill kūlanaʻokoʻa mai ka composting ana. No laila, i ka hoʻololi iho uku o PLA hoʻololi iho ka lohi, ano laulā, lawe 2-5 makahiki, akā, me ka hoʻololi iho huahana mai i hoʻohaumiaʻole ai i ka groundwater me ka luku i ka ulu mea kanu, a i luku aku i ka aina mahi, a me ka ho'ōla ia mea nō oo ke kūlana.

Incineration
ka'ā waiwai o PLA mea liʻiliʻi, a me ka piha'ā huahana i ke kalapona'okikene lua a me ka wai, a e ole hoʻohaumiaʻole ai i ka lewa.

PLA lawe makahiki pāhana kumu waiwai - palaoa, cassava a me nā mea kanu like maka mea. Ma hope o fermentation ma microorganisms, lacticʻakika e e extracted, laila PLA e e hua mai ma ke kaʻina hana o ka hoohehee maemae au ia, dehydration polymerization, kiʻekiʻe ka mahana pyrolysis a me ka hooholo polymerization. PLA mea maikaʻi biodegradable waiwai. Ma hope o hoʻolilo, i loko o hoʻokahi makahiki, ka mea hiki ke kūlana i loko o ke kalapona'okikene lua a me ka wai ma microorganisms i loko o ka lepo, a me ka hana ino ana i kā mākou 'ia. PLA mea heʻano o aliphatic polyester me ka walaʻauʻana ano o mau micromolecule mea. PLA he maikai machanical waiwai, haʻahaʻa shrinkage, a me ka mea hiki i ka palapala noi loa kemikala Ka lula ea Ke o, kekahi ia Ka hoʻomanoʻia ia i loko o ka? Iecaianoaaiiie o AEeAaOA mea, disposable tableware, ka hale uila mea hāpai mīkini iwi, puluniu, 3D lako etc.

No ka mea, PLA kaulike mai ka pāhana kanu resoures akā,ʻaʻole i kaʻaila kā-ma muli kuʻuna lula ea, pela no ka mea, hikiʻoiaʻiʻo ike ikehu-wale no a me ka enviromental maluhia, a me PLA ua manaoia e ia i ka loa i olelo mua iaʻi hou "? Aneeo mea".
