Nūhou - Ke wehe ʻana i ka ʻala palaoa i loko o nā bioplastics: He aha kāna kuleana?

I ko mākou ola i kēlā me kēia lā, loaʻa nā huahana plastik i nā wahi āpau. Eia nō naʻe, ʻo ka piʻi ʻana o nā pilikia kaiapuni i hoʻokumu ʻia e nā plastics kuʻuna ua hoʻoikaika i ka poʻe e ʻimi i nā mea ʻē aʻe. ʻO kēia kahi e komo ai nā bioplastics. I waena o lākou, he hana koʻikoʻi ka kānana starch ma ke ʻano he mea maʻamau i ka bioplastics. No laila, he aha ke kuleana oʻo ka cornstarch i loko o nā bioplastics?

1. He aha nā Bioplastics?
ʻO nā bioplastics nā plastics i hana ʻia mai nā kumuwaiwai hou e like me nā mea kanu a i ʻole microorganisms. ʻAʻole e like me nā plastics kuʻuna, hana ʻia nā bioplastics mai nā kumuwaiwai hou, no laila e emi iho ka hopena o ke kaiapuni. Hoʻohana maʻamau ʻia ka starch kulina ma ke ʻano he mea nui i ka bioplastics.

2. ʻO ke kuleana o ka kānana starch i nā bioplastics

ʻEkolu mau hana koʻikoʻi ka mākiko kulina:
He kuleana ko Cornstarch i ka hoʻonui ʻana, hoʻopaʻa ʻana a me ka hoʻomaikaʻi ʻana i nā waiwai hana i loko o nā bioplastics. He polymer ia i hiki ke hoʻohui ʻia me nā polymers biodegradable a i ʻole plasticizers e hana i nā hale paʻa. Ma ka hoʻohui ʻana i nā mea hoʻohui kūpono i ka starch kulina, hiki ke hoʻoponopono ʻia ka paʻakikī, ka maʻalahi a me ka helu degradation o nā bioplastics, i kūpono ia no nā hiʻohiʻona noiʻi like ʻole.
Hoʻonui i ka ikaika Mechanical: ʻO ka hoʻopili ʻana i ka starch kulina hiki ke hoʻomaikaʻi i ka paʻakikī a me ka ikaika tensile o nā bioplastics, e ʻoi aku ka lōʻihi.

Hoʻomaikaʻi i ka Hana Hana Hana: ʻO ka loaʻa ʻana o ka mākiko kulina e ʻoi aku ka malleable o nā bioplastics i ka wā o ka hana ʻana, e hoʻomaʻamaʻa i ka hana ʻana i nā huahana like ʻole.

Eia kekahi, loaʻa i ka starch kulina ka biodegradability maikaʻi loa. Ma lalo o nā kūlana kaiapuni kūpono, hiki i nā microorganisms ke wāwahi i ka mākiko kulina i loko o nā pūhui organik maʻalahi, i ka hopena e loaʻa ai ka hōʻino piha. ʻAe kēia i nā bioplastics e hana hou ʻia ma hope o ka hoʻohana ʻana, e hōʻemi ana i ka pollution kaiapuni.

Eia nō naʻe, ke kau nei ka mākiko kulina i kekahi mau pilikia. No ka laʻana, i loko o nā kaiapuni kiʻekiʻe a i ʻole ka haʻahaʻa haʻahaʻa, hiki i nā bioplastics ke nalowale i ke kūpaʻa, e pili ana i ko lākou ola a me ka hana. No ka hoʻoponopono ʻana i kēia pilikia, ke hana nei nā ʻepekema i ka loaʻa ʻana o nā mea hoʻohui hou a i ʻole ka hoʻomaikaʻi ʻana i nā kaʻina hana e hoʻonui ai i ka pale wela a me ka pale ʻana o ka wai o nā bioplastics.

3. Nā hoʻohana ʻana o Corn Starch in Specific Bioplastics

ʻO ka hoʻohana ʻana i ka starch kulina i nā bioplastics kikoʻī e like me nā waiwai i makemake ʻia a me ka hoʻohana ʻana i ka huahana hope. Eia kekahi mau laʻana:

Polylactic Acid (PLA): ʻO ka PLA kahi bioplastic i loaʻa mau mai ka mākiko kulina. Hoʻohana ʻia ka mākiko kulina ma ke ʻano he meaʻai no ka hana ʻana i ka waikawa lactic, a laila polymerized e hana i ka PLA. ʻO ka PLA i hoʻoikaika ʻia me ka mākiko kulina e hōʻike ana i nā waiwai mechanical i hoʻomaikaʻi ʻia, e like me ka ikaika tensile a me ka pale ʻana i ka hopena. Eia kekahi, hiki i ka hoʻohui ʻana i ka starch kulina ke hoʻonui i ka biodegradability o PLA, e kūpono ana i nā noi kahi e hopohopo nui ai ka nohona, e like memea ʻoki ʻoki ʻoki ʻia, pūʻolo meaʻai, a me nā kiʻi ʻoniʻoni mulch mahiʻai.

Polyhydroxyalkanoates (PHA): ʻO ka PHA kekahi ʻano bioplastic hiki ke hana ʻia me ka hoʻohana ʻana i ka mākiko kulina ma ke ʻano he kumu kalapona. Hoʻomoʻa ʻia ka mākiko kulina e nā microorganism e hana i ka polyhydroxybutyrate (PHB), he ʻano PHA. ʻOi aku ka maikaʻi o ke kūpaʻa wela a me nā waiwai mechanical i nā PHA i hoʻoikaika ʻia me ka mākū kulina. Loaʻa kēia mau bioplastics i nā noi i nā ʻāpana like ʻole, me ka hoʻopili ʻana, nā mea lapaʻau, a me ka mahiʻai.

ʻO Bioplastics Mākaʻikaʻi Mākaʻikaʻi: I kekahi mau hihia, ua hana pololei ʻia ka mākiko kulina i bioplastics me ka ʻole o ka pono o nā ʻanuʻu polymerization hou. Loaʻa i nā bioplastics i hoʻokumu ʻia i ka starch kahi hui ʻana o ka starch kulina, plasticizers, a me nā mea hoʻohui e hoʻomaikaʻi ai i ka hana a me nā waiwai hoʻohana hope. Hoʻohana ʻia kēia mau bioplastics i nā noi e like me nā ʻeke hoʻolele, nā ipu meaʻai, a me nā papa ʻaina hoʻopau.

Hoʻohui ʻia me nā Polymers Biodegradable ʻē aʻe: Hiki ke hui pū ʻia ka mākū kulina me nā polymers biodegradable ʻē aʻe, e like me polyhydroxyalkanoates (PHA), polycaprolactone (PCL), a i ʻole polybutylene adipate-co-terephthalate (PBAT), e hana i nā bioplastics me nā waiwai i hoʻohālikelike ʻia. Hāʻawi kēia mau mea hoʻohui i kahi kaulike o ka ikaika mechanical, hiki ke maʻalahi, a me ka biodegradability, e kūpono ana iā lākou no nā noi like ʻole mai ka hoʻopili ʻana i ka mahiʻai.

4. Ka hopena

ʻO ke kuleana o ka starch kulina i nā bioplastics ma mua o ka hoʻonui ʻana i ka hana; kōkua pū ia i ka hōʻemi ʻana i ka hilinaʻi ʻana i nā plastic petroleum-based maʻamau, e alakaʻi ana i ka hoʻomohala ʻana i nā mea pili kaiaola. Me ka holomua o ka ʻenehana, manaʻo mākou e ʻike i nā huahana bioplastic hou aʻe e pili ana i nā kumuwaiwai hou e like me ka starch kulina.

I ka hōʻuluʻulu manaʻo, hoʻokani ʻia ka starch kulina i ka hana multifaceted i ka bioplastics, ʻaʻole wale i ka hoʻonui ʻana i ka paʻa o ka paʻa o nā plastics akā hoʻolaha pū i ko lākou biodegradability, a laila e hōʻemi i ka hopena o ke kaiapuni. Me ka holomua ʻenehana a me ka hana hou, ua mākaukau nā bioplastics e pāʻani i kahi ʻoi aku ka nui o ka lawe ʻana i nā pono hou aku i ko kākou honua.
