ʻAʻole wale ka Thermoplastic polyurethane (TPU) i nā waiwai o ka polyurethane cross-linked, e like me ka ikaika kiʻekiʻe, ke kūpaʻa lole kiʻekiʻe, akā loaʻa nō hoʻi nā waiwai thermoplastic o nā mea polymer linear, i hiki ke hoʻonui ʻia kāna noi i ka māla plastik.ʻOi loa i nā makahiki i hala iho nei, ua lilo ʻo TPU i mea hoʻomohala wikiwiki loa.
Loaʻa i ka TPU nā hiʻohiʻona kiʻekiʻe kiʻekiʻe, kiʻekiʻe kiʻekiʻe, paʻakikī, a me nā hiʻohiʻona kūʻokoʻa o ka wā kahiko, e lilo ia i mea makua a me nā mea pili i ke kaiapuni.Loaʻa iā ia ka ikaika kiʻekiʻe, ka paʻakikī maikaʻi, ke kūpaʻa ʻaʻahu, ke kū anuanu, ka pale ʻana i ka aila, ke kū ʻana o ka wai, ka pale ʻana i ka wā kahiko, a me ka pale ʻana i ka wā, ʻaʻole hiki ke hoʻohālikelike ʻia me nā mea plastik ʻē aʻe.I ka manawa like, he kiʻekiʻe ka wai a me ka moisture permeability, ka pale ʻana i ka makani, ke kū anuanu, nā waiwai antibacterial, ka pale ʻana i ka mold, a me nā hana maikaʻi he nui, e like me ka mālama ʻana i ka mahana, ka pale UV, a me ka hoʻokuʻu ʻana i ka ikehu.
Loaʻa i ka TPU kahi ākea o nā mahana hana.Hiki ke hoʻohana ʻia ka hapa nui o nā huahana no ka manawa lōʻihi ma ke ʻano o -40-80 ℃, a hiki i ka mahana hana pōkole ke hiki i 120 ℃.ʻO nā ʻāpana palupalu i ka ʻāpana ʻāpana o nā macromolecules TPU e hoʻoholo i kā lākou hana haʻahaʻa haʻahaʻa.ʻO ka TPU ʻano polyester he haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa a me ka maʻalahi ma mua o ka polyether type TPU.Hoʻoholo ʻia ka hana haʻahaʻa haʻahaʻa o TPU e ka wela hoʻololi aniani mua o ka ʻāpana palupalu a me ka mahana palupalu o ka ʻāpana palupalu.ʻO ka laulā hoʻololi aniani e pili ana i ka ʻike o ka ʻāpana paʻakikī a me ke degere o ka hoʻokaʻawale ʻana ma waena o nā ʻāpana palupalu a paʻakikī.Ke piʻi aʻe nei ka ʻike o nā ʻāpana paʻakikī a me ka emi ʻana o ke kiʻekiʻe o ka hoʻokaʻawale ʻana, ua hoʻonui pū ʻia ka laulā hoʻololi aniani o nā ʻāpana palupalu e like me ia, kahi e alakaʻi ai i ka hana haʻahaʻa haʻahaʻa.Inā hoʻohana ʻia ka polyether me ka hoʻohālikelike maikaʻi ʻole me ka ʻāpana paʻakikī e like me ka ʻāpana palupalu, hiki ke hoʻomaikaʻi ʻia ka maʻalahi haʻahaʻa haʻahaʻa o TPU.Ke piʻi aʻe ka paona molekala pili o ka ʻāpana palupalu a i ʻole ka hoʻopili ʻia ʻana o ka TPU, e piʻi pū ka degere o ka like ʻole ma waena o nā ʻāpana palupalu a paʻakikī.I nā wela kiʻekiʻe, mālama nui ʻia kāna hana e nā ʻāpana kaulahao paʻakikī, a ʻoi aku ka kiʻekiʻe o ka paʻakikī o ka huahana, ʻoi aku ka kiʻekiʻe o kona wela lawelawe.Eia kekahi,ʻaʻole pili wale ka hana wela kiʻekiʻe i ka nui o ka mea hoʻonui kaulahao, akā i hoʻopiliʻia hoʻi e keʻano o ke kaulahao.No ka laʻana, ʻoi aku ka kiʻekiʻe o ka wela hoʻohana o TPU i loaʻa ma ka hoʻohana ʻana i (hydroxyethoxy) benzene ma ke ʻano he mea hoʻonui kaulahao ma mua o ka TPU i loaʻa ma ka hoʻohana ʻana i ka butanediol a i ʻole hexanediol ma ke ʻano he kaulahao.Hoʻopili ke ʻano o ka diisocyanate i ka hana wela kiʻekiʻe o TPU, a me nā diisocyanates like ʻole a me nā mea hoʻonui kaulahao e like me nā ʻāpana paʻakikī e hōʻike ana i nā helu heheʻe like ʻole.
I kēia manawa, ʻoi aku ka nui o ka hoʻohana ʻana o ke kiʻi TPU, a ke ulu mālie nei ia mai nā kāmaʻa kuʻuna, textiles, lole i ka aerospace, pūʻali koa, uila a me nā kula ʻē aʻe.I ka manawa like, ʻo ke kiʻi ʻoniʻoni TPU kahi mea ʻenehana hou e hiki ke hoʻololi mau ʻia.Hiki iā ia ke hoʻonui i kāna kahua noi ma o ka hoʻololi ʻana i nā mea waiwai, ka hoʻoponopono ʻana i ke ʻano kumu, ka hoʻoponopono ʻana i ke kaʻina hana a me nā ala ʻē aʻe, no laila e hāʻawi ana i ke kiʻi TPU i kahi ākea e hoʻohana ai.I ka wā e hiki mai ana, e hoʻomaikaʻi ʻia ka pae ʻenehana ʻenehana, E hele hou aku ka noi o TPU.
He aha nā noi o kēia manawa o nā mea TPU i kā mākou hui?
Ke piʻi nui nei nā kaʻa i ko mākou ola, ke piʻi nei ka koi no ka pale kaʻa ma waena o nā mea nona nā kaʻa.ʻO ke kiʻiʻoniʻoni pale pena TPU ka hopena kūpono e hoʻoponopono ai i kēia koi.
ʻO kekahi o nā hiʻohiʻona o ke kiʻi ʻoniʻoni pale pena TPU, ʻo ia ke kūpaʻa waimaka maikaʻi, hiki ke pale pono i ka hopena o nā mea ʻoi e like me ka ʻiliʻili a me ke one ma ke alanui, a pale i ke kino mai nā ʻōpala a me nā niho.ʻAʻohe pono e hopohopo hou e pili ana i ka pōʻino i ka wā kaʻa, a hiki iā ʻoe ke nānā hou aku i ke ala a me ka ʻike hoʻokele i ka wā e hoʻokele ai.
Eia kekahi, ʻoi aku ka maikaʻi o ke kūʻē ʻana o ka wā i ke kiʻi pale pena TPU.Inā ikaika ka lā o ka lā, ka ua waika, a i ʻole nā mea haumia, hiki i kēia kiʻi pale pena ke pale pono i ka pena o ke kaʻa mai ka pōʻino, e mālama mau i ke kaʻa me kahi hiʻohiʻona nani.
ʻO ka mea kupanaha loa, ʻo kā mākou kiʻiʻoniʻoni pale pena TPU he hana hoʻōla pilikino.Ma hope o ka ʻoki ʻia ʻana, hiki i kāna mea hana ke hoʻoponopono iā ia iho i kahi wahi mahana kūpono, e ʻae ai i ke kino e ola hou e like me ka wā ma mua a hoʻolōʻihi i ke ola lawelawe o ke kiʻi pale pena.
ʻAʻole hāʻawi wale kēia kiʻi ʻoniʻoni pale pena TPU i ka pale ākea, akā kau pū kekahi i ka manaʻo nui i ka pale ʻana i ke kaiapuni.ʻO ke kiʻi ʻoniʻoni pale pena i hana ʻia me nā mea pili i ke kaiapuni, ʻaʻole ia e hoʻokau i ke kaumaha o ke kaiapuni, e like me ka ʻimi ʻana i ka huakaʻi ʻōmaʻomaʻo e nā poʻe hou.
ʻO ka hoʻokuʻu ʻia ʻana o ka kiʻiʻoniʻoni pale pena TPU e hōʻailona ana i kahi kipi i ke kahua o ka pale automotive, e hāʻawi ana i nā ʻōnaehana pale ʻoi aku ka holomua a hilinaʻi no nā mea nona nā kaʻa.E apo i ka pale ʻōmaʻomaʻo, e hanu pū kā mākou kaʻa a me ka honua.
E ʻoluʻolu e nānā i ka QR code ma luna e hoʻopili pololei iā mākou.
