ʻO ka Polyurethane kahi mea e puka mai ana i nā mea polymer organik, i kapa ʻia ʻo "The Fifth Plastic", a hoʻohana nui ʻia i nā ʻāpana he nui o ka ʻoihana aupuni no kāna hana maikaʻi loa.I kēia manawa, ʻo Kina ka mea hana nui loa o ka polyurethane ma ka honua, e helu ana ma kahi o 45% o ka hana polyurethane honua.Nui nā ʻano huahana polyurethane, a ʻo polyurethane elastomer kekahi o lākou.ʻO ka polyurethane elastomer he pūʻulu o nā mea elastomer i loaʻa i nā hui carbamate hou aʻe ma ke kaulahao nui polymer, a he mea polymer hiki ke hoʻōla maikaʻi ma hope o ka hoʻopau ʻia ʻana o ka ikaika o waho.
Hiki ke hoʻokaʻawale ʻia ka polyurethane elastomers i ka thermoplastic polyurethane elastomers (TPU), hoʻolei i ka polyurethane elastomers (CPU) a me ka hui ʻana i nā polyurethane elastomers (MPU) e like me nā kaʻina hana like ʻole, a ʻo TPU ka mea nui loa.ʻO ka ʻoihana TPU kahi lālā o ka ʻoihana polyurethane, aia ma lalo o ke kaulahao ʻoihana kemika holoʻokoʻa, kokoke i ka mākeke mea kūʻai hope.
01 Ka hoʻokaʻawale ʻana o nā elastomers polyurethane
ʻO TPU kahi huahana polyurethane elastomer.ʻO nā mea maka e like me polyols, MDI, BDO, adipic acid, a me ka ethylene glycol i koi ʻia no kāna hana ʻana, ʻo ia nā huahana ʻaila a i ʻole nā huahana, a he mau huahana lalo o ka petrochemical.ʻO TPU kahi lālā o nā mea elastomer thermoplastic.He mea polymer i polymerized mai ʻekolu mau mea maka: diisocyanate, macromolecular polyol, a me ka mea hoʻonui kaulahao (low molecular diol).
Ke hoʻohālikelike ʻia me nā mea plastik a me nā mea hao, TPU he ākea ākea o ka paʻakikī, nā ʻano mechanical koʻikoʻi, ke kūpaʻa kiʻekiʻe / haʻahaʻa haʻahaʻa maikaʻi, ka hana hoʻoponopono maikaʻi, ka hana kūlohelohe maikaʻi loa, ka plasticity ikaika, ka designability ikaika, a me ka ʻike maikaʻi loa.ʻAʻole wale ka elasticity kiʻekiʻe o nā mea lāʻau lapaʻau, akā loaʻa nō hoʻi ka ikaika kiʻekiʻe o nā plastics engineering.
02 TPU mea waiwai
Ua hoʻomohala mua ʻia ʻo TPU e Bayer i ka makahiki 1958, a ua hoʻomohala a hoʻokomo ʻia nā hui kemika nui ma ʻEulopa a me ʻAmelika Hui Pū ʻIa.I ka makahiki 1970, ua hoʻokomo ʻo Iapana i nā lako hana TPU Kelemania a hoʻokomo i ka ʻenehana hana TPU i Taiwan.Ua ʻike ʻia ʻo Mainland China i ka ʻenehana hana TPU mai ka makahiki 1980, akā ʻaʻole i loaʻa i nā holomua i ka noiʻi a me ka hoʻomohala ʻana a me ka ʻenehana.Ma hope o nā makahiki 1990, me ka piʻi nui ʻana o ka mākeke no nā mea TPU, ma hope o ka komo ʻana o nā ʻoihana kālā ʻEulopa, ʻAmelika a me Taiwan i ka ʻāina nui, ua hoʻomaka kekahi mau ʻoihana ʻāina e hana a kūʻai aku iā TPU.
03 Moʻolelo hoʻomohala o ka ʻoihana TPU honua a me Kina
Mahalo i kāna hana huahana maikaʻi loa, ua hoʻonui nui ʻia ka noi mākeke no TPU ma nā ʻoihana waiwai nui e like me nā mea kūʻai aku i kēlā me kēia lā, hana ʻoihana, olakino olakino, pale aupuni a me ka ʻoihana koa.I nā makahiki i hala iho nei, ua hoʻokuʻu ʻia ka mana hana TPU hou o koʻu ʻāina i kēlā me kēia, a ua hoʻonui mau ʻia ka nui o ka hana TPU ma 2018 a me 2019. Mai 2014 a i 2019, ʻoi aku ka kiʻekiʻe o ka nui o ka ulu ʻana o ka TPU home ma 15.46%. .I ka makahiki 2019, hoʻomau ka nui o ka ʻoihana TPU o koʻu ʻāina, me ka hoʻopuka ʻana ma kahi o 512,900 tons.Ua ʻoi aku ka maikaʻi o koʻu ʻāina ma mua o ʻEulopa a me ʻAmelika Hui Pū ʻIa e lilo i mea hana nui a me ka mea kūʻai aku i ka TPU ma ka honua, a ʻo ka awelika o ka hoʻohana ʻana i ka makahiki ua mālama i ka ulu wikiwiki ma kahi o 10%.
04 Ka Papa Hana o TPU Production ma Kina mai 2014 a 2019
Hoʻopilikia ʻia e ka hanana Xiangshui i 2019, ua wikiwiki ke aupuni i ka hana hou ʻana o nā paka kemika.I ka manawa like, ua hoʻonui ke kumukūʻai o ka isocyanate maka i ke kumu kūʻai o kekahi mau hale liʻiliʻi.Eia naʻe, hoʻomau nā mea hana i hoʻokumu ʻia, me Huafon, BASF, a me Meirui, e hoʻonui i kā lākou mau laina a hoʻonui i ka hana, a hoʻonui i kā lākou ʻoihana ma ka mākeke.Ke piʻi mau nei ka manaʻo o ka ʻoihana.Ma waena o nā mea hoʻolako TPU home, ʻo Huafon Group a me Yantai Wanhua ke noho i nā kūlana kiʻekiʻe i ka hiki ke hana.
05 Ka hoʻokaʻawale ʻana o ke ʻano hana TPU a Kina i 2019
ʻOiai he kiʻekiʻe ka pālākiō hana TPU kūloko o koʻu ʻāina, ʻaʻohe ona pōmaikaʻi i nā mahina ʻāpana.ʻOi loa ma ka mākeke waena a kiʻekiʻe, ʻo nā hui multinational e like me BASF a me Huntsman i loaʻa nā pono ʻenehana koʻikoʻi.Ma o nā hiʻohiʻona hoʻokele maikaʻi, ua hoʻomaikaʻi lākou i ka hana a me ka maikaʻi o ka huahana i ka wā e hōʻemi ana i nā kumukūʻai hana huahana, e noho ana i kahi mahele nui o nā mākeke waena waena a kiʻekiʻe a kiʻekiʻe.I kēia manawa, nele ka hapa nui o nā mea hana TPU ma koʻu ʻāina i nā pono ʻenehana koʻikoʻi, ka hoʻolālā huahana hoʻokahi, a me ka holomua lohi i nā huahana hou, e hopena i ka hoʻokūkū nawaliwali o ka mākeke, a he paʻakikī ke hoʻonui pono i ka waiwai o ka ʻoihana.
ʻO ke kuhikuhi o ka hoʻomohala ʻenehana, ka pālākiō, ke ʻano hoʻokūkū, ka ulu ʻana, a me ka pae waiwai o ka ʻoihana TPU e hilinaʻi pololei i ka noi mākeke o nā ʻoihana o lalo.
Hōʻike ka ʻikepili i ka wā e hoʻololi mālie ʻia ai nā mea hoʻonaninani kuʻuna a me nā mea palaka e nā mea pili i ke kaiapuni, e hoʻomau ka hoʻohana ʻana i ka TPU, a e hoʻohana nui ʻia i nā ʻāpana he nui o ka hoʻokele waiwai aupuni.Hoʻohana nui ʻia ʻo TPU i nā paipu, nā kiʻiʻoniʻoni, nā mea uila, nā mea kāmaʻa, nā ʻāpana kaʻa, nā encapsulation i hoʻololi ʻia, ka hoʻoili ʻana i nā ʻoihana, nā mea hoʻopili, nā uea a me nā ʻāpana ʻē aʻe.Ma waena o lākou, ʻo nā mea kāmaʻa ka mākeke mea kūʻai nui no TPU, helu no 40% o ka hoʻohana TPU.
06 ʻO ke ʻano noi noi TPU ma lalo o Kina
ʻO koʻu ʻāina ka mea hana nui loa a me ka mea hoʻopuka i nā kāmaʻa, a ʻoi aku ka nui o kāna huahana ma mua o 50% o ka huina honua.'O ka hana'enehana o nā mea ho'okahi, he mea nui ia i ka hana kāma'a.Ke hoʻohālikelike ʻia me nā mea kūʻokoʻa kuʻuna, loaʻa iā TPU nā pōmaikaʻi i ka hana, a ke hoʻonui nei ka hoʻohana ʻana i kēlā me kēia lā.Ma waena o lākou, loaʻa i ka ETPU nā pōmaikaʻi maikaʻi loa i ka resilience a me ka haʻalulu haʻalulu.Hiki i ka sole i hana ʻia ke hoʻopili pono i ka hopena o ka lepo a kū i ka wāwae, e hāʻawi ana i ka hopena cushioning kiʻekiʻe.
Ma ka holoʻokoʻa, loaʻa i ka ʻoihana TPU nā hiʻohiʻona o kahi kiʻekiʻe o nā kumukūʻai maka, ka wikiwiki o ka hoʻonui ʻana i ka huahana, nā kikoʻī like ʻole a me nā hiʻohiʻona, a me ka ʻokoʻa ʻokoʻa o nā pono o ka mea kūʻai aku.No laila, pili ka pae waiwai o ka ʻoihana e nā kumu like ʻole e like me ka fluctuations o nā kumukūʻai maka, nā mana hoʻomohala huahana hou, a me nā pae lawelawe o nā mea kūʻai aku.Me ka hoʻomaka ʻana o nā kulekele kūloko a me nā ana e pili ana i ke olakino haʻuki o ka poʻe noho, a me ka hoʻomaikaʻi ʻana i ka ʻai a me ka hiki ke hoʻolilo i nā mea haʻuki, ʻo ka ulu ʻana o ka makemake o nā mea kūʻai aku no nā kāmaʻa haʻuki kiʻekiʻe e kōkua i ka hoʻomaikaʻi ʻana i ka wahi noi o ka TPU. ʻoihana.Ma ka ʻaoʻao ʻē aʻe, i ka mākeke kiʻekiʻe no nā ʻano like me ka TPU calendered, TPU lapaʻau, a me ka TPU kūʻokoʻa kiʻekiʻe, hilinaʻi nui ka ʻāina i ka lawe ʻana mai.Me ka hōʻiliʻili ʻenehana lōʻihi a me ka hoʻopukapuka R&D o nā ʻoihana TPU kūloko, manaʻo ʻia e uhaki i ka monopoly o nā hui ʻē aʻe a hoʻonui i ka wahi ʻokoʻa kūloko.
