I-Thermoplastic Polyurethane (TPU) ayigcini nje ngokunama-polyurethane axhumene ne-cross-okuxhumekile, njengamandla aphezulu, ukumelana okuphezulu, kepha futhi inezindawo ze-thermoplastic zezinto zokwakha eziqondile, ukuze isicelo saso selulekwe emkhakheni wepulasitiki. Ikakhulu emashumini eminyaka amuva, i-TPU isiphenduke ingenye yezinto ezisheshayo ze-polymer.
I-TPU inokungezwani okuphezulu kakhulu, ukungezwani okuphezulu, ukuqina, kanye nezimpawu zokumelana nokugula, okwenza kube nezinto ezivuthiwe nezemvelo. Inamandla aphezulu, ubulukhuni obuhle, ukuphefumula, ukumelana nokubandakanyeka, ukumelana namafutha, ukumelana kwamanzi, ukumelana kwamanzi, okungenakuqhathaniswa nezinye izinto zepulasitiki, ezingenakuqhathaniswa nezinye izinto zepulasitiki. Ngasikhathi sinye, inemvume ephezulu kakhulu futhi umswakama, ukumelana komoya, ukumelana nokubandakanyeka, izakhiwo ze-antibacterial, ukumelana okubumba, nemisebenzi eminingi emihle kakhulu, njengokuqinisekiswa kwe-UV, kanye nokukhulelwa kwamandla.
I-TPU inamazinga okushisa ahlukahlukene. Imikhiqizo eminingi ingasetjenziswa isikhathi eside ebangeni le -40-80 ℃, kanti izinga lokushisa elisebenzayo lesikhathi esifushane lingafinyelela ku-120 ℃. Izingxenye ezithambile ekwakhekeni kwengxenye ye-TPU Macromoleks inquma ukusebenza kwawo okushisa okuphansi. Uhlobo lwePolyester TPU lunokusebenza okuphansi okuphansi kokushisa nokuguquguquka kunohlobo lwe-polyther TPU. Ukusebenza okushisa okuphansi kwe-TPU kunqunywa ngokushisa kwengilazi okuqala kwengxenye ethambile kanye nokushisa okuthambile kwengxenye ethambile. Ibanga lokuguqulwa kwengilazi lincike kokuqukethwe kwengxenye enzima kanye nezinga lokuhlukaniswa kwesigaba phakathi kwezingxenye ezithambile nezinzima. Njengoba okuqukethwe izingxenye ezinzima kukhuphuka futhi izinga lokuhlukaniswa kwesigaba lincipha, uhla lwe-Glass ukuguqulwa kwezingxenye ezithambile nalo luyandisa ngokufanele, okuzoholela ekusebenzeni okuphansi okuphansi. Uma ama-polythelekile ukuhambisana okungekuhle nengxenye enzima kusetshenziswa njengengxenye ethambile, ukuguquguquka okushisa okuphansi kwe-TPU kungathuthukiswa. Lapho isisindo se-molecular se-molecular sengxenye ethambile sikhuphuka noma i-TPU ifakwa, izinga lokungalingani phakathi kwezingxenye ezithambile nezinzima zizokhula. Emazingeni okushisa aphezulu, ukusebenza kwawo kugcinwa ikakhulu yizingxenye ezinzima zamaketanga, futhi kuphakama ubulukhuni bomkhiqizo, kuphakama izinga lokushisa lenkonzo. Ngaphezu kwalokho, ukusebenza okushisa okuphezulu akuhlobene nenani le-chain eledlule, kepha kuthonywe futhi ngohlobo lwe-Chain Extender. Isibonelo, izinga lokushisa elisetshenzisiwe le-TPU elitholwe ngokusebenzisa (i-hydroxyethoxy) i-benzender extender extender iphakeme kunaleso ye-TPU etholwe ngokusebenzisa i-butanediol noma i-hexanediol njenge-chain extender. Uhlobo lwe-diisocyanate libuye lithinta ukusebenza okushisa okuphezulu kwe-TPU, kanye ne-diisocyates ehlukile kanye nama-chain elengwa njengezingxenye ezinzima zibonisa amaphuzu ahlukile ancibilikisa.
Njengamanje, ubukhulu besicelo sefilimu ye-TPU buba banzi futhi banzi, futhi kancane kancane kuyanda kusuka ezicathulweni zendabuko, izindwangu, okokugqoka kuya e-aerospace, ezempi, ama-elekthronikhi kanye nezinye izinkambu. Ngasikhathi sinye, ifilimu ye-TPU yinto entsha yezimboni engaguqulwa ngokuqhubekayo. Kungakhulisa insimu yayo yohlelo lokusebenza ngokuguqulwa kwezinto ezingavuthiwe, ukulungiswa kwefomula ezibonakalayo, ukusebenza kwenqubo yokukhiqiza nezinye izindlela, ngaleyo ndlela kunikeze i-TPU ifilimu isikhala esengeziwe sokusebenzisa. Esikhathini esizayo, izinga lobuchwepheshe bezimboni lizothuthukiswa, ukusetshenziswa kwe-TPU kuzoqhubeka.
Yiziphi izinhlelo zokusebenza zamanje zezinto ze-TPU enkampanini yethu?
Njengoba izimoto zidlala indima ebaluleke kakhulu ezimpilweni zethu, isidingo sokuvikelwa kwezimoto phakathi kwabanikazi bezimoto siyanda. Ifilimu yokuvikela ukupenda kwe-TPU iyisisombululo esifanelekile sokubhekana nalesi sicelo.
Enye yezimpawu zefilimu yokuvikela ukupenda kwe-TPU ukumelana kwayo okuhle kwezinyembezi, okungamelana ngempumelelo nomthelela wezinto ezibukhali ezinjenge-gravel kanye nesihlabathi esemgwaqweni, futhi uvikele umzimba kusuka kumakhonkolo nakuqunjelwa. Akusekho isidingo sokukhathazeka ngomonakalo ongaba khona ngesikhathi sokushayela, futhi ungagxila kakhulu emgwaqweni nangokuhlangenwe nakho kokushayela lapho ushayela.
Ngaphezu kwalokho, ifilimu yokuvikela ukupenda i-TPU inokumelana kwesimo sezulu esihle kakhulu. Noma ngabe ukukhanya kwelanga okuqinile, ukuqina kwemvula, noma ukungcola, le filimu yokuvikela upende ingavikela upende wemoto ngokuthembekile ekulimaleni, ukugcina imoto ihlala inokubukeka okukhanyayo.
Okumangazayo ngokwengeziwe ukuthi ifilimu yethu yokuvikela ukupenda nge-TPU nayo inomsebenzi wokuziphilisa. Ngemuva kokuklanywa kancane, impahla yayo ingazilungisa endaweni efudumele efudumele, evumela umzimba ukuthi ululame njengangaphambili futhi unwebe impilo yenkonzo yefilimu yokuvikela upende.
Le filimu evikela ukupenda nge-TPU ayihlinzeki ngokuvikela ngokuphelele, kepha futhi igcizelela kakhulu ukuvikelwa kwemvelo. Ifilimu evikela ukupenda eyenziwe ngezinto ezinobungane zemvelo ngeke idale umthwalo emvelweni, okuhambisana nokuphishekela ukuhamba okuluhlaza ngabantu banamuhla.
Ukwethulwa kwe-TPU evikela ukupenda ukuphepha kumaki emkhakheni wokuvikelwa kwezimoto, ukuhlinzeka ngezixazululo ezithuthukile nezithembekile zokuvikela abanini bezimoto. Yamukela ukuvikelwa okuluhlaza, izimoto zethu nomhlaba ziphefumule ndawonye.
Sicela uskene ikhodi ye-QR ngenhla ukuxhumana nathi ngqo.
