Hoʻopiʻi ʻia ka hoʻohana ʻana i nā plastic synthetic i loaʻa mai ka ʻaila ma muli o nā pilikia kaulana loa o ka haumia keʻokeʻo. ʻO ka ʻimi ʻana i nā kumuwaiwai kalapona hou e like me ke ʻano he mea koʻikoʻi a wikiwiki. Ua noʻonoʻo nui ʻia ka polylactic acid (PLA) i mea hiki ke hoʻololi i nā mea waiwai maʻamau. Ma ke ʻano he kumu waiwai hou i loaʻa mai ka biomass me nā waiwai mechanical kūpono, biocompatibility maikaʻi, a me ka degradability, ua ʻike ʻo PLA i ka ulu ʻana o ka mākeke pahū i ka ʻenekinia plastics, biomedical material, textile, nā noi hoʻopihapiha ʻenehana. Eia nō naʻe, ʻo kona haʻahaʻa haʻahaʻa wela a me ka haʻahaʻa haʻahaʻa e hoʻopaʻa nui i kāna mau noi.

Ua hana ʻia ka hui ʻana o ka polylactic acid (PLA) a me ka thermoplastic silicone polyurethane (TPSiU) elastomer e hoʻoikaika i ka PLA.

Ua hōʻike nā hopena ua hoʻohui maikaʻi ʻia ʻo TPSiU i PLA, akā ʻaʻohe hopena kemika. ʻAʻohe hopena o ka hoʻohui ʻana o TPSiU i ka mahana hoʻololi aniani a me ka wela hoʻoheheʻe o PLA, akā ua hoʻemi iki i ka crystallinity o PLA.

Ua hōʻike ka morphology a me ka hoʻoikaika mechanical analysis i ka maikaʻi ʻole o ka thermodynamic compatibility ma waena o PLA a me TPSiU.

Ua hōʻike ʻia nā haʻawina ʻano Rheological i ka hoʻoheheʻe ʻana o PLA/TPSiU he wai pseudoplastic maʻamau. I ka hoʻonui ʻia ʻana o ka ʻike o TPSiU, ʻike ʻia ka viscosity o ka hui ʻana o PLA/TPSiU i ke ʻano o ka piʻi mua ʻana a laila hāʻule. He hopena koʻikoʻi ka hoʻohui ʻana o TPSiU i nā waiwai mechanical o ka hui ʻana o PLA/TPSiU. I ka 15 wt% ka nui o ka TPSiU, hiki i ka elongation i ka haki ʻana o ka hui PLA/TPSiU i 22.3% (5.0 mau manawa o ka PLA maʻemaʻe), a hiki i ka ikaika hopena i 19.3 kJ/m2 (4.9 mau manawa o ka PLA maʻemaʻe), e hōʻike ana i ka hopena paʻakikī maikaʻi.

Hoʻohālikelike ʻia me TPU, ʻoi aku ka maikaʻi o ka paʻakikī o ka TPSiU ma PLA ma kekahi ʻaoʻao a ʻoi aku ka maikaʻi o ka pale wela ma kekahi ʻaoʻao.

Eia naʻe,SILIKE SI-TPVʻO ia ka mea i hoʻopaʻa ʻia i ka ikaika vulcanized thermoplastic Silicone-based elastomers. Ua huki nui ʻia ma muli o kona ʻili me ka ʻili silky Unique a me ka ʻili-friendly touch, maikaʻi loa o ka hōʻiliʻili ʻana i ka lepo ， ʻoi aku ka maikaʻi o ka pale ʻana, ʻaʻole i loko o ka plasticizer a me ka ʻaila palupalu, ʻaʻohe koko / pili i ka pilikia, ʻaʻohe ʻala.

Eia kekahi, ʻoi aku ka maikaʻi o ka paʻakikī i ka PLA.

ʻO kēia ʻano mea palekana a me ka hoʻonaʻauao kūlohelohe, hāʻawi i kahi hui maikaʻi o nā waiwai a me nā pōmaikaʻi mai ka thermoplastics a me ka huila silicone i hoʻopili piha ʻia. kūpono no ka ʻili hiki ke hoʻohana ʻia, nā plastics ʻenekinia, nā mea biomedical, textile, nā noi hoʻopili ʻenehana.
