Nui nā kumu waiwai maka
ʻO nā mea maka i hoʻohana ʻia no ka hana ʻana i ka polylactic acid (PLA) mai nā kumuwaiwai hou e like me ke kulina, me ka ʻole o ka pono o nā kumuwaiwai kūlohelohe e like me ka ʻaila a i ʻole ka lāʻau, no laila e kōkua ai i ka pale ʻana i ka emi ʻana o nā kumu waiwai aila.
Nā waiwai kino kiʻekiʻe
Ua kūpono ʻo PLA no nā ʻano hana like ʻole e like me ka puhi ʻana a me ka thermoplastics, e maʻalahi i ka hana ʻana a pili i kahi ākea o nā huahana plastik, ka meaʻai meaʻai, nā pahu meaʻai wikiwiki, nā lole i ulana ʻole ʻia, nā ʻoihana a me nā lole kīwila, a loaʻa iā ia kahi mea nui loa. māke kūʻai kūʻē.
Biocompatibility
Loaʻa iā PLA ka biocompatibility maikaʻi loa, a me kāna huahana degradation, L-lactic acid, hiki ke komo i ka metabolism kanaka. Ua ʻae ʻia e ka US Food and Drug Administration (FDA) a hiki ke hoʻohana ʻia ma ke ʻano he lāʻau lapaʻau lapaʻau, injectable capsules, microspheres, a me nā implants.
Hiki i ka hanu maikaʻi
He maikaʻi ka hanu PLA, ka oxygen permeability, a me ka carbon dioxide permeability, a loaʻa iā ia ke ʻano o ka hoʻokaʻawale ʻana. He mea maʻalahi ka hoʻopili ʻana i nā maʻi maʻi a me ka ʻōpala i ka ʻili o nā plastic biodegradable, no laila aia nā pilikia palekana a me ka maʻemaʻe. Eia nō naʻe, ʻo PLA wale nō ka plastic biodegradable me nā waiwai antibacterial a me nā anti-mold maikaʻi.
Hiki i ka biodegradability
ʻO PLA kekahi o nā mea biodegradable i noiʻi nui ʻia ma Kina a me nā ʻāina ʻē aʻe, a ʻo kāna mau wahi noi wela nui ʻekolu ʻo ia ka ʻeke meaʻai, nā papa ʻaina hoʻopau, a me nā mea lapaʻau.
ʻO ka PLA, ka mea i hana nui ʻia mai ka lactic acid maoli, he biodegradability maikaʻi a me ka biocompatibility, a he haʻahaʻa haʻahaʻa haʻahaʻa ka hopena o ke kaiapuni o kona ola ma mua o nā mea waiwai. Ua manaʻo ʻia ʻo ia ka mea ʻoi loa ka maikaʻi o ka ʻōmaʻomaʻo ʻōmaʻomaʻo no ka hoʻomohala ʻana.
Ma ke ʻano he ʻano hou o nā mea olaola maʻemaʻe, loaʻa iā PLA nā manaʻo mākeke nui. ʻO kāna mau waiwai kino maikaʻi a me kona aloha kaiapuni e hoʻohana nui ʻia ka PLA i ka wā e hiki mai ana.
