ʻO ka ʻokoʻa ma waena o TPU polyester a me polyether, a me ka pilina ma waena o polycaprolactone a me TPU

ʻO ka ʻokoʻa ma waena o ka TPU polyester a me ka polyether, a me ka pilina ma waenapolycaprolactone TPU

ʻO ka mea mua, ka ʻokoʻa ma waena o TPU polyester a me polyether

ʻO ka Thermoplastic polyurethane (TPU) kahi ʻano mea elastomer hana kiʻekiʻe, i hoʻohana nui ʻia i nā ʻano āpau. Wahi a ke ʻano ʻokoʻa o kāna ʻāpana palupalu, hiki ke hoʻokaʻawale ʻia ka TPU i ke ʻano polyester a me ke ʻano polyether. Nui nā ʻokoʻa i ka hana a me ka hoʻohana ʻana ma waena o nā ʻano ʻelua.

ʻO ka Polyester TPU ka ikaika kiʻekiʻe a me ke kūpaʻa ʻana, nā waiwai tensile, nā waiwai kūlou a me ke kūpaʻa solvent maikaʻi loa. Eia kekahi, maikaʻi ke kūpaʻa kiʻekiʻe kiʻekiʻe a kūpono i nā noi ma nā wahi wela kiʻekiʻe. Eia nō naʻe, ʻilihune ka pale hydrolysis o ka polyester TPU, a maʻalahi ke hoʻouka ʻia e nā mole wai a me ka haki.

He ʻokoʻa,polyether TPUʻike ʻia no kona ikaika kiʻekiʻe, ke kūpaʻa hydrolysis a me ke kūpaʻa kiʻekiʻe. He maikaʻi loa kāna hana wela haʻahaʻa, kūpono no ka hoʻohana ʻana i nā wahi anuanu. Eia nō naʻe, ʻoi aku ka nāwaliwali o ka ʻili a me ka ikaika haʻihaʻi o ka polyether TPU, a ʻoi aku ka haʻahaʻa o ka tensile, aahu a me ka waimaka o ka polyether TPU i ka polyester TPU.

ʻO ka lua, ka polycaprolactone TPU

ʻO ka Polycaprolactone (PCL) kahi mea polymer kūikawā, ʻoiai ʻo TPU ka pōkole no ka polyurethane thermoplastic. ʻOiai he mau mea polymer lāua, ʻo polycaprolactone ponoʻī ʻaʻole ia he TPU. Eia nō naʻe, i ke kaʻina hana o TPU, hiki ke hoʻohana ʻia ka polycaprolactone ma ke ʻano he ʻāpana palupalu koʻikoʻi e hana me ka isocyanate e hana i nā elastomers TPU me nā waiwai maikaʻi loa.

ʻO ke kolu, ka pilina ma waena o polycaprolactone a meTPU masterbatch

He kuleana koʻikoʻi ka Masterbatch i ka hana ʻana o TPU. ʻO ka Masterbatch kahi prepolymer kiʻekiʻe, i hana maʻamau i nā ʻano like ʻole e like me ka polymer, plasticizer, stabilizer, etc. I ke kaʻina hana o TPU, hiki i ka masterbatch ke pane me ka mea hoʻonui kaulahao, crosslinking agent, etc., e hana i nā huahana TPU me nā waiwai kikoʻī.

Ma ke ʻano he mea polymer hana kiʻekiʻe, hoʻohana pinepine ʻia ka polycaprolactone ma ke ʻano he mea nui o ka masterbatch TPU. Ma ka prepolymerization o ka polycaprolactone me nā mea ʻē aʻe, hiki ke hoʻomākaukau ʻia nā huahana TPU me nā waiwai mechanical maikaʻi loa, ka pale hydrolysis a me ke kūpaʻa haʻahaʻa haʻahaʻa. Loa'a i kēia mau huahana ka laulā o nā mea ho'ohana i nā lole i'ike'ole'ia, nā mea lapa'au, nā kāma'a ha'uki a pēlā aku.

ʻO ka hā, nā hiʻohiʻona a me nā noi o polycaprolactone TPU

Noʻonoʻo ka Polycaprolactone TPU i nā pono o ka polyester a me ka polyether TPU, a ʻoi aku ka maikaʻi o nā waiwai piha. ʻAʻole wale ka ikaika mechanical kiʻekiʻe a me ke kūpaʻa ʻana, akā hōʻike pū kekahi i ke kūpaʻa hydrolysis maikaʻi a me ke kūpaʻa haʻahaʻa haʻahaʻa. Hana kēia i ka polycaprolactone TPU i kahi ola lawelawe lōʻihi a paʻa i nā kaiapuni paʻakikī a loli.

Ma ke kahua o ka lole i ʻike ʻole ʻia, ua lilo ka polycaprolactone TPU i mea i makemake ʻia ma muli o kāna mau waiwai piha. Hiki iā ia ke pale aku i ka hoʻoneʻe ʻana o nā mea o waho e like me ka ua waika, ka lepo, nā kulu manu, a hōʻoia i ka hana a me ke ola o nā lole kaʻa. Eia kekahi, ma nā kahua o nā lāʻau lapaʻau, nā mea haʻuki, a me nā mea ʻē aʻe, ua loaʻa i ka polycaprolactone TPU ka nānā ākea no kona palekana a me ka hilinaʻi.

I ka pōkole, aia nā ʻokoʻa koʻikoʻi ma waena o ka TPU polyester a me ka polyether i ka hana a me ka hoʻohana ʻana, ʻoiai ʻo polycaprolactone, ma ke ʻano he mea nui o ka TPU, hāʻawi i nā huahana TPU maikaʻi loa. Ma ka hoʻomaopopo hohonu ʻana i nā pilina a me nā ʻano ma waena o kēia mau mea, hiki iā mākou ke koho maikaʻi a hoʻopili i nā huahana TPU kūpono e hoʻokō i nā pono o nā kahua like ʻole.
