I-Thermoplastic polyurethane, evame ukwaziwa ngokuthi i-TPU, isiphenduke ithuluzi elibalulekile kwezokwakha emhlabeni wanamuhla wezimboni. Leli-elastomer elimangalisayo lihlangana phakathi kokuguquguquka okufana nerabha nokucubunguleka okufana nepulasitiki, linikeza abaklami inhlanganisela eyivelakancane yokuthambeka, amandla, nokuqina emkhiqizweni owodwa. Njengoba izimboni zifuna izingxenye ezilula, izimpilo zemikhiqizo ezinde, nezindlela zokucubungula ezigcina imvelo, i-TPU isiphenduke into ekhethwayo ezinhlelweni eziningi. Kusukela ekhasini elivikelayo le-smartphone yakho kuya kocingo lokufihla ngaphakathi emotweni kagesi, i-TPU iletha ukusebenza okungenakufaniswa amapholima ajwayelekile. Emabhizinisini afuna umhlinzeki wethembekile wezinto ze-TPU, ukuqonda amandla kanye nezinzuzo zomnotho zale nto yisinyathelo sokuqala ekwenzeni izinqumo ezihlakaniphile zokuthenga. I-Dongguan Mier Plastic Material Co., Ltd. isebenze iminyaka eminingi ithuthukisa ukunikezwa kwama-pellets nama-granules e-TPU asebenza kahle kakhulu, isiza abakhiqizi emhlabeni wonke bakhe imikhiqizo engcono. Kulo mhlahlandlela obanzi, sihlola umlando, izakhiwo, izinhlelo zokusebenza, nezinzuzo zokukhiqiza ezenza i-TPU ibalulekile ezimbonini zanamuhla.

I-Thermoplastic polyurethane yaqala ukutholakala ngasekupheleni kweminyaka yama-1930 nasekuqaleni kwama-1940, lapho ososayensi ababecwaninga nge-chemistry ye-polyurethane bethola ukuthi ezinye izinhlanganisela zingacutshungulwa njengama-thermoplastics kunokuba ziqiniswe zibe ama-thermosets aqinile. Lokhu kutholakala kwavumela into ukuthi incibilikiswe, ibunjwe, futhi isetshenziswe kabusha, okuyisici esayihlukanisa nerabha evamile futhi kwavula umnyango wokukhiqizwa ngobuningi. Kuyo yonke iminyaka yama-1950 naya kwama-1960, i-TPU yathola ukusetshenziswa ezintweni ezikhethekile njengamarola ezimboni, amapayipi, nezingxenye zezicathulo, lapho ukumelana kwayo nokugqokwa kwabonakala kubalulekile ngokushesha. Izinkinga zikawoyela zama-1970 zasheshisa ucwaningo ngezinto ezilula, futhi i-TPU yaba yisikhundla esithandwayo sezingxenye ezisindayo zensimbi nezepulasitiki eziqinile emkhakheni wezimoto. Ngeminyaka yama-1990, intuthuko kubuchwepheshe be-polymerization yathuthukisa kakhulu ukungaguquguquki nokucaca kwe-TPU, okuyivumela ukuthi isetshenziswe kumafilimu acwebezelayo, amapayipi ezokwelapha, ne-electronics yabathengi. Namuhla, imakethe yomhlaba wonke ye-TPU ibalwa ngezigidigidi zamadola futhi iyaqhubeka nokukhula ngezinga elihle lonyaka, iqhutshwa yisidingo sezimoto zikagesi, amadivayisi agqokwayo, nokupakishwa okugxile ekongiweni kwemvelo. Ukuguquka kwe-TPU kuwubufakazi bokuthi i-polymer eyodwa ingakwazi kanjani ukuzivumelanisa nezidingo ezishintshayo zezimboni cishe eminyakeni eyikhulu yokusungula izinto ezintsha. Abakhiqizi manje balindele ukuthi umhlinzeki wabo we-TPU anganikezeli nje kuphela into eluhlaza, kodwa nobuchwepheshe bezobuchwepheshe nokuguquguquka kwezinhlanganisela okuhambisana nalawa mikhuba.

Lapho onjiniyela behlola izinto zokwakha zezingxenye eziguquguqukayo, ngokuvamile bacabangela izinketho ezimbalwa, okuhlanganisa ama-thermoplastic elastomers (TPE), i-polyvinyl chloride (PVC), i-silicone, kanye nerabha yemvelo noma yokwenziwa. I-TPU ihlala ihamba phambili kune-TPE ekuqineni kokugqokwa nasekuqineni kokudabuka, okwenza kube ukukhethwa okuthandwayo ezinhlelweni ezidinga ukugqoka okukhulu njengamabhande okuthutha, amagiya, namakesi okuvikela. Uma kuqhathaniswa ne-PVC, i-TPU inikeza ukuguquguquka okungcono kakhulu emazingeni okushisa aphansi, ukumelana namakhemikhali okuphezulu, futhi ayinazo izinkinga zokufuduka kwe-plasticizer ezingabangela ukuba i-PVC ibe brittle noma ikhiphe izithasiselo eziyingozi ngokuhamba kwesikhathi. I-Silicone igqama ekushiseni okwedlulele nasezinhlelweni zezokwelapha, kodwa ibiza kakhulu futhi ayinakuqina kwemishini kwe-TPU uma ibekwa ekugobeni nasekushayweni okuphindaphindiwe. IRabha inikeza ukunwebeka okuhle kanye nokudamba, kodwa idinga i-vulcanization futhi ayikwazi ukuphinda isetshenziswe kalula njenge-thermoplastic polyurethane, engakwazi ukuncibilikiswa futhi icutshungulwe kabusha izikhathi eziningi. Ngokombono wezindleko, i-TPU ingaphezu kwezinto zokwakha ezijwayelekile ezifana ne-PVC kodwa ingaphansi kwe-silicone nama-rubber compounds asebenza kahle kakhulu, inikeza ibhalansi ekhangayo yokusebenza nenani. Izindleko zizonke zobunikazi, okuhlanganisa amathuluzi, izikhathi zomjikelezo, nokutholwa kabusha kwe-scrap, ngokuvamile kwenza i-TPU ibe ukukhethwa okonga kakhulu uma zonke izinto zokukhiqiza sezicatshangelwe. Abakhiqizi be-TPU baseShayina, ikakhulukazi, benze amazinga asezingeni eliphezulu afinyeleleka ngamanani entengo abancintisana nawo abakwazi ukuwafinyelela.

Kubalulekile futhi ukuqaphela ukuthi igama elithi "TPE" liyisigaba esibanzi okungenzeka ukuthi ngokobuchwephesha sifaka i-TPU, okungadala ukudideka ngesikhathi kukhethwa izinto zokusebenza. Abathengi abaningi bacabanga ukuthi zonke izinto ze-TPE zisebenza ngendlela efanayo, kodwa i-TPU imele izinga eliphezulu lokusebenza kulo mndeni, ehlukaniswa ngamakhemikhali ayo e-polyurethane kanye nezakhiwo zayo ezingcono zomshini. Nakuba amazinga athambile e-TPE elungele izinto zokubamba, ama-seal, kanye nokusetshenziswa kokufulela ngaphezulu, i-TPU iyona khetho ehamba phambili lapho umkhiqizo wokugcina kufanele umelane nezindawo ezinobungozi, imiphetho ebukhali, noma ukugoba okuqhubekayo. Ezinhlelweni ezinjengamakesi omakhalekhukhwini kanye nezindlu zamathuluzi kagesi, umhlinzeki we-TPU angahlinzeka ngamazinga aqinile angokwezifiso asukela ku-75 Shore A athambile kuya ku-75 Shore D okuqinile, okunikeza abaklami ithuba elikhulu. I-PVC isashibhile ngekhilogremu ngayinye, kodwa isimo sayo semvelo kanye nokulinganiselwa kokusebenza kuye kwaholela ekutheni imikhiqizo eminingi ishintshele ku-TPU eminyakeni yamuva. Ekugcineni, isinqumo phakathi kwalezi zinto sincike ezidingweni ezithile zohlelo lokusebenza, futhi ukusebenza nomhlinzeki onolwazi njenge-Mier kuqinisekisa ukuthi ukhetha izinga elifanele lomkhiqizo wakho.

Iphrofayili yokusebenza kwe-thermoplastic polyurethane isekelwe ezinsikeni ezine eziyisisekelo: amandla emishini, ukumelana nokugqokwa, ukuzinza kwamakhemikhali, nokubekezelela izinga lokushisa. I-TPU ibonisa amandla amahle kakhulu okudonsa, ngokuvamile edlula ama-40 MPa kumagridi okujova, okuvumela izingxenye ezinodonga oluncane ukuthi zithwale imithwalo ebalulekile yesakhiwo ngaphandle kokuqhekeka. Ukumelana kwayo nokugqokwa kuyindumasi, ngokuvamile kudlula irabha yemvelo kanye nama-elastomer amaningi okwenziwa ngezinga elikhulu, yingakho i-TPU isetshenziswa ezicathulweni zezicathulo ezisezingeni eliphezulu kanye nasemasondweni ezimboni ezisindayo. Ngokwamakhemikhali, i-TPU imelana namafutha, amafutha okugcoba, uphethiloli, kanye nezinhlobonhlobo zezincibilikisi, okwenza kube ukukhetha okuhle kakhulu kwezivalo zezimoto, amahose e-hydraulic, nezingxenye zemishini ezithintana njalo namakhemikhali anamandla. Into leyo iphinde ibonise ukumelana okuhle ne-ozone, imisebe ye-ultraviolet, nokuhlaselwa amagciwane, iqinisekisa impilo ende yokusebenza ezindaweni zangaphandle nasezindaweni zasolwandle. Ukubekezelela izinga lokushisa kungenye inzuzo ebalulekile, njengoba amagridi amaningi e-TPU ehlala eguquguquka emazingeni okushisa aphansi kakhulu njengo--40°C kuyilapho emelana nokusebenza okuqhubekayo ngaphezu kuka-100°C. Kufanele kuqashelwe ukuthi i-TPU izinzile kakhulu ngokwe-hydrolysis, okusho ukuthi imelana nokonakala okubangelwa umswakama nomswakamo, okuyinto ebalulekile kumadivayisi ezokwelapha nezimpahla zabathengi ezihlanjululwa njalo. Lezi zakhiwo ezihlanganisiwe zenza i-TPU ibe yinto yobunjiniyela eguquguqukayo ngendlela ehlukile, evalela igebe phakathi kwama-elastomer nama-thermoplastics aqinile.

Ngaphezu kwalezi zici eziyisisekelo zokwakheka, i-TPU nayo inikeza ukucaca okuhle kwezithombe kwezinye izinhlobo, okwenza kube nokwenzeka ukukhiqiza imikhiqizo ecwebezelayo noma ekhanyayo efana namabhande ewashi, okhiye, namafilimu okupakisha. Le nto ingacutshungulwa ngokujova, ukukhipha, ukufutha, ngisho nokuphrinta nge-3D, okusho ukuthi abakhiqizi abavalelwe endleleni eyodwa yokukhiqiza. Ukunwebeka nokubuyela esimweni kwe-TPU kumangalisa, okuvumela imikhiqizo ukuthi ibuyele esimweni sayo sokuqala ngemva kokunwebeka noma ukucindezelwa okuphindaphindiwe ngaphandle kokonakala okungapheli. Lokhu "kukhumbula" yikho okwenza amabhande e-TPU, amabhande, nama-seal athembeke iminyaka eminingi yokusetshenziswa. Ngaphezu kwalokho, ama-TPU pellets atholakala ngezinhlobonhlobo zokuqina, imibala, nezithasiselo, okuvumela abakhiqizi ukuthi balungise ukumelana nomlilo, izakhiwo zokumelana nogesi, noma ukuzinza kwe-UV ukuze bahlangabezane nezindinganiso zokulawula. Ezinkampanini ezidinga izinto eziqinisekisiwe zezokwelapha noma zokuthintana nokudla, abakhiqizi be-TPU abathembekile bangahlinzeka ngezigaba ezihambisana nezidingo ze-ISO, FDA, noma i-RoHS. Ukuqonda lezi zici zokusebenza kubalulekile lapho uhlola umthengisi we-TPU, ngoba akuzona zonke izigaba ezilinganayo futhi ukungaguquguquki kwezinto kuthinta ngqo ikhwalithi yomkhiqizo.
