He aha ka polycaprolactone?
Polycaprolactone, i hoʻopau ʻia e like me PCL, he semi crystalline polymer a me kahi mea hiki ke hoʻopau ʻia. Hiki ke hoʻokaʻawale ʻia ka Polycaprolactone i loko o ka lāʻau lapaʻau a me ka ʻoihana ʻoihana ma ke ʻano o nā pauka, nā ʻāpana, a me nā microspheres. ʻO 60000 a me 80000 nā paona molekala maʻamau, a hiki ke hoʻonohonoho pono ʻia nā kaupaona molecular kiʻekiʻe a haʻahaʻa paha.
ʻO ka Polycaprolactone nā koi wela haʻahaʻa a hiki ke hoʻoheheʻe ʻia i nā haʻahaʻa haʻahaʻa. Loaʻa iā ia ka adhesion maikaʻi a me ka hoʻohālikelike maikaʻi me nā ʻano polymers. ʻO kāna hiʻohiʻona maikaʻi loa ʻaʻole ia he mea ʻawaʻawa a biodegradable. ʻO ia ma muli o kona mau hiʻohiʻona kiʻekiʻe i hoʻohana nui ʻia i nā ʻano hana like ʻole, ʻoi aku hoʻi i ka lāʻau lapaʻau. E nānā kākou i nā waiwai o PCL?

Ma hope o ka hoʻomaopopo ʻana i nā ʻano o ka polycaprolactone ma luna, ua hele mākou i ka nīnau a mākou e hopohopo nei. ʻO ia, he aha ka polycaprolactone e hoʻohana ai?
He aha ka polycaprolactone e hoʻohana ai?
1. Nā ʻano lāʻau lapaʻau
Hiki ke hoʻohana ʻia no ke kuʻi ʻana i ka ʻoki ʻana a hiki ke komo ʻia e ke kino kanaka. Hiki ke hoʻohana ʻia i nā splints orthopedic, bandage resin, paʻi 3D, a me nā mea ʻē aʻe. Eia kekahi, ʻo ia ka mea nui o ka "Maiden Needle".
2. Polyurethane resin kahua
Ma ke kahua o ka polyurethane resin, hiki ke hoʻohana 'ia i loko o ka uhi, inika, wela hehee ai adhesives, non ulana lole adhesives, kāmaʻa mea, structural adhesives, etc. Ka hapa nui o ka uhi i hoʻohana 'ia e like me automotive primers, ili ili, a me nā mea hale. Ma muli o kona ʻoi aku ka maikaʻi o ka pale ʻana i ka wela, ke kūpaʻa māmā, a me ke kūpaʻa ʻelemakule, hoʻohana nui ʻia ia i ka ʻili ʻili.
3. Mea hoʻopili meaʻai
Ma muli o kona degradability, hiki ke hoʻohana ʻia ka polycaprolactone i nā kiʻi ʻoniʻoni puhi a me nā pahu pahu meaʻai. Ma muli o kona hopena kū'ē wela, hiki ke hoʻohana ʻia e like me nā pahu pahu, ʻaʻole ia e pale wale i ke kaiapuni, akā e hōʻoia i ka palekana.
4. Nā kahua ʻē aʻe
Hiki ke hoʻohana ʻia nā hiʻohiʻona hana lima, nā kala kalakala, nā uhi pauka, nā hoʻololi plastik, a me nā mea ʻē aʻe.
He aha ka manaʻo o ka polycaprolactone?
ʻOiai ua hoʻohana nui ʻia ka polycaprolactone, ʻo kona mau manaʻo hoʻomohala kekahi kumu nui o ka hopohopo. ʻO ka mea mua, ua aʻo mākou he polycaprolactone nā hiʻohiʻona o ka degradation piha. Me ka hoʻomohala ʻana o ke kaiāulu, ua piʻi ka ʻike o ka poʻe i ka mālama ʻana i ke kaiapuni, a ua wikiwiki ka hoʻohana ʻana i nā plastic biodegradable. No laila, he waiwai hoʻohana nui ka polycaprolactone i ka lāʻau lapaʻau, hana, a me nā ʻano ʻoihana, aPCL Hiki iā ia ke alakaʻi i nā mea he nui. Me ka holomua o ka ʻenehana lapaʻau, ke ulu nui nei ka ʻenehana paʻi 3D. Hoʻohana maʻamau ia i ka lāʻau lapaʻau ma ke ʻano he ʻenehana ʻenehana scaffold mea hiki ke hoʻopili ʻia a hoʻopau ʻia e ke kino kanaka. Ma ke ʻano he ʻelele o nā mea biodegradable hou i kūkulu ʻia, loaʻa i ka polycaprolactone kahi manaʻo hoʻomohala maikaʻi, a e piʻi aʻe ka koi. Manaʻo wau he mea kōkua kēia ʻatikala iā ʻoe.
