Nā ʻeke hoʻopili PLA a me PLA compostable

Nā Pōmaikaʻi o PLA

1.Biodegradability: Ma hope o ka hoʻolei ʻia ʻana o PLA, hiki ke hoʻohaʻahaʻa loa ʻia i loko o ka wai a me ke kalapona ʻokikene ma lalo o nā kūlana kikoʻī, a hoʻi hou i ke kaʻapuni kūlohelohe, e pale ana i ka haumia lōʻihi i ke kaiapuni i hoʻokumu ʻia e nā plastics kuʻuna.
2. Nā kumuwaiwai hou: Hoʻohui nui ʻia ka PLA mai ka waikawa lactic i unuhi ʻia mai ka palaoa kulina, ke kō a me nā mea kanu ʻē aʻe, he mau kumuwaiwai hou ia, a hoʻemi i ka hilinaʻi ʻana i nā kumuwaiwai petroleum.
3. Loaʻa iā ia ka permeability maikaʻi o ka ea, ka permeability oxygen a me ke kalapona dioxide permeability, loaʻa iā ia ka waiwai o ka hoʻokaʻawale ʻana i ka ʻala. Hoʻopili pinepine nā virus a me nā ʻōpala i ka ʻili o nā plastics biodegradable, no laila aia nā hopohopo e pili ana i ka palekana a me ka maʻemaʻe. Eia nō naʻe, ʻo PLA wale nō ka plastic biodegradable me nā waiwai anti-bacteria a me anti-mold maikaʻi loa.

ʻAno hoʻohaʻahaʻa o ka PLA

1.Hydrolysis: Ua haki ka hui ester o ke kaulahao nui, no laila e hōʻemi ana i ke kaumaha molekala.
2. Ka hoʻokaʻawale wela: kahi hanana paʻakikī e alakaʻi ai i ka puka ʻana mai o nā hui like ʻole, e like me nā molekala māmā a me nā oligomers linear a me cyclic me nā kaumaha molekala like ʻole, a me ka lactide.
3. Photodegradation: Hiki i ka radiation ultraviolet ke hoʻoulu i ka hōʻino ʻana. He kumu nui kēia i ka hōʻike ʻana o PLA i ka lā i loko o nā plastics, nā ipu hoʻopili, a me nā noi kiʻiʻoniʻoni.

Ka hoʻohana ʻana o PLA ma ke kahua hoʻopili

Hoʻohana ʻia nā mea PLA ma nā ʻano kahua like ʻole. I ka ʻoihana hoʻopili, hoʻohana nui ʻia ka kiʻiʻoniʻoni PLA i ka hoʻopili waho o ka meaʻai, mea inu a me nā lāʻau lapaʻau e pani i ka hoʻopili plastik kuʻuna, i mea e hoʻokō ai i ke kumu o ka palekana o ke kaiapuni a me ke kūpaʻa.

He loea ʻo PACK MIC i ka hana ʻana i nā ʻeke hana hou a me nā ʻeke compost i hana kūikawā ʻia.

ʻAno ʻeke: ʻeke sila ʻekolu ʻaoʻao, ʻeke kū, ʻeke zipper kū, ʻeke lalo palahalaha
ʻAno mea: pepa kraft / PLA
