He aha ka meaʻo Thermoppus Pyurethane elastomer?

ʻO Polyurethane Elastomer Elastomer he mau mea likeʻoleʻo Pyuretorhane (ʻo nāʻano'ē aʻe e pili ana iā Poliredhane, PyureThane Cing a Pyourethane, PyureTonhane Cing a Pyourethane Famore ʻO nāʻano nui o Plyurethorhane elastomers e hoʻounaʻiaʻo Plyuretarrs, Huhūʻia e CPU, a huiʻia e like me MPU).

ʻO TPU keʻano o ka polyomhane elastomhane e hiki ke hoʻopiliʻia e ka ho'ēmiʻana e ka hoʻomehana a hoʻopauʻia e ka hopena. Hoʻohālikelikeʻia me CPU a me MPU,ʻo TPU ka liʻiliʻi a iʻole he liʻiliʻi a iʻole ka hoʻopiliʻana ma keʻano he cross-pili i konaʻano maʻamau. ʻO kāna kaula molecular ka mea maʻamau, akā aia kekahi o keʻano kino o keʻano. ʻO kēia ka meaʻo ka moʻoleloʻo ka plyurethas

Keʻano a me ka papa o TPU

ʻO Theirmoplastashanes Pyurethane Elastomer he (AB) Block Polymer. Hōʻike i kahi polymer polymer (ester a iʻole polyether B E hōʻike i kahi diol i loaʻa i nā carbon carbon 2-12 pololei pololei i kapaʻiaʻo Chain.

I ke kūlana o ka Thermopplustic Pyurethane Elastomer, ua kapaʻiaʻo Cogment A i kapaʻia he'āpana palupalu, kahi palupalu o ka maʻalahi a me ka palupaluʻo Tpu; Ua kiʻiʻia ka Chain Urethane ma waena o ka hopena ma waena o keʻano o ka BAGment a me Isocynate Ma ka hoʻoponoponoʻana i ka pae o nā'āpana o A a me B S Segment, nā huahana TPU me nāʻano likeʻole a me nā mea hana likeʻole.

Wahi a keʻano o ka māhele palupalu, hiki ke hoʻokaʻawaleʻia i loko o kaʻano polyester, heʻano booterane, ka huiʻana o ka poʻe matericene. Wahi a keʻano paʻakikī paʻakikī, hiki iā ia ke hoʻokaʻawale i keʻano urethane a me Urethane urea Ua hoʻokaʻawaleʻia ka helu maʻamau i loko o nāʻano polyester a me keʻano polyether.

He aha nā mea e pono ai no TPU Synthesis?

(1) POLOLOM DIOL

ʻO ka Diorthecular Diol me kahi kaupaona molena mai ka 500 a me 4000 a me nā hui o ka cup.

Ka polymer diol kūpono kūpono no tpu elastomer hiki ke hoʻokaʻawaleʻia i ka polyester a me nā polyether: polyester acidizetrame adititic (pba) ε pcl. Hoʻokomoʻiaʻo Polyethers i ka polyocyprocklene ether glycol (ppg), tetrabydrofuran polycol (ptmg), etc.

(2) diisocynate

He liʻiliʻi ka liʻiliʻi o ka molabular akāʻo ka hana he mea houʻole,ʻaʻole wale ke pāʻani i ka hana o ka hoʻopiliʻana i keʻano o nāʻano kino a me nāʻano paʻakikī. Ua pili nā Diisogyanates i ka TPU: MathLeyne Diphenynate (MDI), 1 HMDI), 1 HMDI), 1 HMDI), 1 HMDI), 1 HMDI), 1 hMDI), diisocynate (pxdi), etc.

(3) Hoʻonuiʻo Chain

ʻO ka papa inoa me ka nui moleka o 100 ~ 350, nona nā'āpana moleka ʻO nā mea nui o nā mea hoʻohana i kūpono no TPU e pili ana iā TPU i ka 1,4-bodeadirool (BDO), 1,4-Bis -l (2-HYEEXETERMITHOL (PXG), ATC.

ʻO ka noiʻana o TPU ma keʻano he mea hoʻokele

I mea e hōʻemi ai i nā kumukūʻai huahana a loaʻa i nā hana hou aku,ʻo Polyurethane e hiki ke hoʻohana i nā mea hoʻonaninani a nā mea hana e pili ana i nā mea kūʻai

Ma muli o kona mau polatrity kiʻekiʻe, hiki i ka polyurethane e kūpono i nā pale a iʻole nā'ōpala, e like me ka clloricated e hana i nā huahana lapaʻau ʻO ka hui pūʻana me ka bos ke hoʻololi i nā thermoplastic engmopplastic no ka hoʻohanaʻana; I ka wā e hui pūʻia me Poycarbonate (PC), he mau mea pono e like me ka paleʻana, a me ka paleʻana o nā manu; I ka wā i hui pū ai me ka polyester, hiki ke hoʻomaikaʻiʻia kona paʻakikī; Eia kekahi, hiki ke kūpono me ka pvc, polyoxxymenene or pvdc; Hiki i ke polyester polyesthane hiki ke kūpono me 15% nitrile subber a 40% nitrile subber / pvc bland; Hiki ke kūponoʻo Pyethe Polyethe Hiki nō ke kūpono pū me ka pilikia acrynityrile (san). Hiki iā ia ke hana i nā'ōnaehana kikowaena (IPN) i nā hoʻonohonoho me nā polysiloxan. ʻO ka hapa nui o nā mea i kohoʻia ma luna o nā mea i'ōleloʻia i luna

I nā makahiki i hala iho nei, aia kahi noiʻi e hoʻonui ana i ka turthehening o Pom e TPU ma Kina. ʻAʻole kūpono wale keʻano o ka TPU a me POMʻaʻole e hoʻomaikaʻi i ke kū'ē kiʻekiʻe a me nā hana o ka TPU Ua hōʻikeʻia kekahi poʻe noiʻi i nā hōʻike hoʻokolohua ma Tensile i hoʻohālikelikeʻia, hoʻohālikelikeʻia i Pomy Matrix ʻO ka hoʻohuiʻana o TPU i nā hopena i hoʻopauʻia me ka hana hoʻomanaʻo hoʻomanaʻo. ʻO ke kahua o ka Crystalline o ka Pom Serves e like me ka phase paʻa o keʻano hoʻomanaʻoʻana,ʻoiai ke kauʻana o ka amorpous tpu Ke hoʻomaka nei keʻano o ka hoʻihoʻi houʻana o ka hope o ka hoʻihoʻiʻana ma kahi o 120 kekona

He mea paʻakikī ke kūpaʻaʻo TPU e like me nā poloka Pools No laila,ʻo nāʻano hana hoʻohālikelike e like me Plasma, Corona, Cherona Ka laʻana, ua hanaʻo nā huahana amerika a me nā hui uila i kaʻoi o ka nui o ka nui o ka nui o ka nui o ka "-5 miliona mauʻano molepekeniha Aʻo ka F2 / O2ʻO ka hoʻomaʻamaʻaʻana i ka maʻiʻo ke kahua mokulele e hiki ke hoʻopiliʻia i nā fuffs pōkole elongated me ka lōʻihi o 6-35mm, hiki ke hoʻomaikaʻi i ka paʻakikī o ka stiffy.

He aha nā wahi noi o TPU?

I ka makahiki 1958, Goodrich Goodrich Communim (i kēia manawa i kākau inoaʻia (i kēia manawa i hoʻopaʻaʻia i ka Lusrazol) i hoʻopaʻa inoa i ka VPU Brand Estane no ka manawa mua. I nā makahiki 40 i hala aku nei, uaʻoi aku ma mua o 20 mau inoa inoa inoa a puni ka honua, a loaʻa i kēlā me kēiaʻano helu o nā huahana. I kēia manawa,ʻo ka nui o nā mea hana TPU ma ke ao nei: Bantsno, Lubrizol,ʻo Libinsey, gula, gula,

E like me kahi elastomer maikaʻi loa,ʻo TPU i kahi ākea ākea o nā huahana i lalo, nā mea i hoʻohana nuiʻia, nā mea hana nani, a me nā papa hana. Ma lalo he mau hiʻohiʻona liʻiliʻi.

Nā huahana kāmaʻa

Hoʻohana nuiʻiaʻo TPU no nā mea kāmaʻa kāmaʻa ma muli o kāna elasticisty maikaʻi loa a me nā pale pale. ʻO nā huahana wāwae wāwae e hōʻoluʻolu nui iā TPU ma mua o nā huahana wāwae wāwae maʻamau, no laila,ʻoi aku ka nui o nā kāmaʻa wāwae kiʻekiʻe.

④ Mea lapaʻau

ʻO TPU kahi palekana palekana a me ke kiʻekiʻe o PVC Greative PVC Breative,ʻaʻole e loaʻa i nā mea hoʻonaninani a me nā mea ola'ē aʻe i nā hopena olakino Eia nō naʻe, ua hoʻohana pinepineʻia ka papa hana extrusion kūikawā a me ka helu injection tpu hiki ke hoʻohana maʻalahiʻia me kahi debugging liʻiliʻi i nā pono pvc i loaʻa.

⑤ nā kaʻa a me nāʻano'ē aʻe o ka halihali

Ma ka uluʻana a me ka paleʻana i nāʻaoʻaoʻelua o ka whebric me ka polylasthane e lawe ana i nā mea he 3-15 i hanaʻia ma mua. Hiki ke hoʻomauʻiaʻo Polyupepa Thermoplastic e kolo mau elastomer e nā'āpana aniani e like me nā'āpana o ke kino ma nāʻaoʻaoʻelua, a me nā briples, a me na briples, a me na pahu lāʻau.
