He aha ka polycaprolactone?
Polycaprolactone, i hoʻopōkole ʻia e like me PCL, he polymer semi crystalline a he mea palaho loa. Hiki ke hoʻokaʻawale ʻia ka Polycaprolactone i ka papa lāʻau lapaʻau a me ka papa ʻoihana ma ke ʻano o nā pauka, nā ʻāpana, a me nā microspheres. ʻO nā kaupaona molekala maʻamau he 60000 a me 80000, a hiki ke hoʻopilikino ʻia nā kaupaona molekala kiʻekiʻe a haʻahaʻa paha.
He haʻahaʻa nā koi mahana o ka Polycaprolactone a hiki ke hoʻoheheʻe ʻia i nā mahana haʻahaʻa. Loaʻa iā ia ka hoʻopili maikaʻi loa a me ka hoʻohālikelike maikaʻi me nā ʻano polymers like ʻole. ʻO kona hiʻohiʻona hoihoi loa ʻaʻole ia he ʻawahia a biodegradable. Ma muli o kona mau ʻano kiʻekiʻe i hoʻohana nui ʻia ai i nā ʻano like ʻole, ʻoi aku hoʻi i ke kahua lapaʻau. E nānā kākou i nā waiwai o PCL?

Ma hope o ka hoʻomaopopo ʻana i nā ʻano o ka polycaprolactone ma luna, ua hiki mai mākou i ka nīnau a mākou e hopohopo nei. ʻO ia hoʻi, he aha ka mea e hiki ai ke hoʻohana ʻia ka polycaprolactone?
He aha ka mea e hiki ai ke hoʻohana ʻia ka polycaprolactone?
1. Nā ʻano lapaʻau
Hiki ke hoʻohana ʻia no ke kuʻi ʻana i ke ʻoki kino a hiki ke komo ʻia e ke kino o ke kanaka. Hiki nō hoʻi ke hoʻohana ʻia i loko o nā ʻāpana orthopedic, nā bandages resin, ka paʻi 3D, a me nā ʻano ʻē aʻe. Eia kekahi, ʻo ia kekahi o nā mea nui o "Maiden Needle".
2. Kahua resin polyurethane
Ma ke kahua o ka resin polyurethane, hiki ke hoʻohana ʻia i nā uhi, nā ʻīnika, nā mea hoʻopili hoʻoheheʻe wela, nā mea hoʻopili lole ʻaʻole i ulana ʻia, nā mea kāmaʻa, nā mea hoʻopili kūkulu, a me nā mea ʻē aʻe. Hoʻohana ʻia ka hapa nui o nā uhi ʻana e like me nā primers kaʻa, nā uhi ʻili, a me nā uhi mea hale like ʻole. Ma muli o kona kūpaʻa wela maikaʻi, kūpaʻa māmā, a me ke kūpaʻa ʻana i ka ʻelemakule, hoʻohana nui ʻia ia i ka ʻili hana.
3. Nā mea hoʻopili meaʻai
Ma muli o kona hiki ke palaho, hiki ke hoʻohana ʻia ka polycaprolactone i nā kiʻiʻoniʻoni hoʻoheheʻe ʻia a me nā pahu ʻōpala meaʻai. Ma muli o kona hopena kūpaʻa wela kupaianaha, hiki ke hoʻohana ʻia e like me nā pahu ʻōpala, ʻaʻole ia e pale wale i ke kaiapuni, akā e hōʻoiaʻiʻo pū i ka palekana.
4. Nā kahua ʻē aʻe
Hiki ke hoʻohana ʻia nā kumu hoʻohālike i hana lima ʻia, nā mea hoʻoluʻu organik, nā uhi pauka, nā hoʻololi plastik, a me nā mea ʻē aʻe, i nā mea hoʻopili.
He aha ka manaʻolana o ka polycaprolactone?
ʻOiai ua hoʻohana nui ʻia ka polycaprolactone, ʻo kona mau manaʻolana hoʻomohala he mea nui hoʻi ia e hopohopo ai. ʻO ka mea mua, ua ʻike mākou he mau ʻano ko ka polycaprolactone o ka hōʻino piha ʻana. Me ka hoʻomohala ʻana o ke kaiāulu, ua piʻi ka ʻike o ka poʻe i ka palekana o ke kaiapuni, a he mea wikiwiki ka hoʻohana ʻana i nā plastics biodegradable. No laila, he waiwai nui ka hoʻohana ʻana o ka polycaprolactone i nā ʻano lapaʻau, hana ʻana, a me nā ʻoihana, aPCL hiki iā ia wale nō ke alakaʻi i nā mea he nui. Me ka holomua o ka ʻenehana lapaʻau, ke ulu nei ka ʻenehana paʻi 3D. Hoʻohana nui ʻia ia ma ke kahua lapaʻau ma ke ʻano he mea hoʻoheheʻe ʻenekinia kiko hiki ke omo ʻia a hoʻokuʻu ʻia e ke kino kanaka. Ma ke ʻano he ʻelele o nā mea biodegradable i hoʻomohala hou ʻia, loaʻa i ka polycaprolactone kahi manaʻolana hoʻomohala maikaʻi, a e piʻi ana ke koi. Manaʻolana wau he kōkua kēia ʻatikala iā ʻoe.
