I-thermoplastic polyurethane (TPU) ayinazo nje kuphela izici zerabha ze-cross-linked polyurethane, njengamandla aphezulu, ukumelana nokuguguleka okuphezulu, kodwa futhi inezimfanelo ze-thermoplastic zezinto ze-polymer eziqondile, ukuze ukusetshenziswa kwayo kunwetshwe ensimini yepulasitiki. Ikakhulukazi emashumini eminyaka amuva nje, i-TPU ibe ngenye yezinto ze-polymer ezithuthuka ngokushesha.
I-TPU inezici ezinhle kakhulu zokumelana nokucindezeleka okuphezulu, ukucindezeleka okuphezulu, ukuqina, kanye nokumelana nokuguga, okwenza ibe yinto evuthiwe futhi enobungani nemvelo. Inamandla aphezulu, ukuqina okuhle, ukumelana nokuguguleka, ukumelana nokubanda, ukumelana namafutha, ukumelana namanzi, ukumelana nokuguga, kanye nokumelana nesimo sezulu, okungenakuqhathaniswa nezinye izinto zepulasitiki. Ngesikhathi esifanayo, inokuvunyelwa kwamanzi okuphezulu kanye nomswakama, ukumelana nomoya, ukumelana nokubanda, izakhiwo zokulwa namagciwane, ukumelana nesikhunta, kanye nemisebenzi eminingi emihle kakhulu, njengokulondolozwa kokushisa, ukumelana ne-UV, kanye nokukhululwa kwamandla.
I-TPU inezinga lokushisa elibanzi lokusebenza. Imikhiqizo eminingi ingasetshenziswa isikhathi eside ebangeni eliphakathi kuka--40-80 ℃, kanti izinga lokushisa lokusebenza lesikhathi esifushane lingafinyelela ku-120 ℃. Izingxenye ezithambile esakhiweni sesigaba sama-macromolecule e-TPU zinquma ukusebenza kwazo kokushisa okuphansi. Uhlobo lwe-TPU lwe-polyester lunokusebenza okuphansi kokushisa okuphansi kanye nokuguquguquka kunohlobo lwe-TPU lwe-polyester. Ukusebenza kokushisa okuphansi kwe-TPU kunqunywa izinga lokushisa lokuqala lokushintsha kwengilazi lesigaba esithambile kanye nokushisa okuthambile kwesigaba esithambile. Ububanzi bokushintsha kwengilazi buxhomeke kokuqukethwe kwesigaba esiqinile kanye nezinga lokuhlukaniswa kwesigaba phakathi kwezingxenye ezithambile neziqinile. Njengoba okuqukethwe kwezingxenye eziqinile kukhuphuka kanye nezinga lokuhlukaniswa kwesigaba liyancipha, ububanzi bokushintsha kwengilazi kwezingxenye ezithambile nabo buyakhula ngokufanele, okuzoholela ekusebenzeni okuphansi kokushisa okuphansi. Uma i-polyether enokuhambisana okuphansi nesigaba esiqinile isetshenziswa njengesigaba esithambile, ukuguquguquka kokushisa okuphansi kwe-TPU kungathuthukiswa. Lapho isisindo sama-molecule esihlobene sesigaba esithambile sanda noma i-TPU ifakwa, izinga lokungahambelani phakathi kwezingxenye ezithambile neziqinile nalo lizokhula. Emazingeni okushisa aphezulu, ukusebenza kwayo kugcinwa kakhulu yizingxenye zeketanga eliqinile, futhi uma ukuqina komkhiqizo kuphakeme, kulapho izinga lokushisa lenkonzo yalo liphakama khona. Ngaphezu kwalokho, ukusebenza kwezinga lokushisa eliphezulu akuhlobene nje kuphela nenani leketanga, kodwa futhi kuthonywa uhlobo lweketanga. Isibonelo, izinga lokushisa lokusetshenziswa kwe-TPU elitholakala ngokusebenzisa (hydroxyethoxy) benzene njengeketanga liphakeme kunele-TPU elitholakala ngokusebenzisa i-butanediol noma i-hexanediol njengeketanga. Uhlobo lwe-diisocyanate luthinta nokusebenza kwezinga lokushisa eliphezulu kwe-TPU, kanye nama-diisocyanates ahlukene kanye namaketanga njengoba izingxenye eziqinile zibonisa amaphuzu ahlukene okuncibilika.
Njengamanje, ububanzi bokusetshenziswa kwefilimu ye-TPU buya bukhula, futhi kancane kancane bukhula kusukela ezicathulweni zendabuko, izindwangu, izingubo kuya ezindiza, ezempi, kuma-elekthronikhi nakwezinye izinkambu. Ngesikhathi esifanayo, ifilimu ye-TPU iyinto entsha yezimboni engashintshwa njalo. Ingandisa insimu yayo yokusetshenziswa ngokuguqulwa kwezinto zokusetshenziswa, ukulungiswa kwefomula yezinto ezibonakalayo, ukwenziwa ngcono kwenqubo yokukhiqiza nezinye izindlela, ngaleyo ndlela inikeze ifilimu ye-TPU isikhala esengeziwe sokuyisebenzisa. Esikhathini esizayo, izinga lobuchwepheshe bezimboni lizothuthukiswa, Ukusetshenziswa kwe-TPU kuzoqhubeka.
Yiziphi izinhlelo zokusebenza zamanje ze-TPU enkampanini yethu?
Njengoba izimoto zidlala indima ebaluleke kakhulu ezimpilweni zethu, isidingo sokuvikelwa kwezimoto phakathi kwabanikazi bezimoto naso siyakhula. Ifilimu yokuvikela upende wezinto ze-TPU iyisisombululo esiphelele sokubhekana nalesi sidingo.
Esinye sezici zefilimu yokuvikela upende ye-TPU ukumelana kwayo okuhle kakhulu nokudabuka, okungamelana ngempumelelo nokushaywa kwezinto ezibukhali njengetshe eliyitshe nesihlabathi emgwaqweni, futhi kuvikele umzimba ekuklwebhekeni nasekuqhekekeni. Akusekho sidingo sokukhathazeka ngomonakalo ongaba khona ngesikhathi sokushayela, futhi ungagxila kakhulu endleleni kanye nesipiliyoni sokushayela lapho ushayela.
Ngaphezu kwalokho, ifilimu yokuvikela upende ye-TPU inokumelana okuhle kakhulu nesimo sezulu. Kungakhathaliseki ukuthi ukukhanya kwelanga okunamandla, ukugqwala kwemvula ene-asidi, noma ukungcola, le filimu yokuvikela upende ingavikela upende wemoto ngokuthembekile ekulimaleni, igcine imoto ibukeka kahle njalo.
Okumangaza nakakhulu ukuthi ifilimu yethu yokuvikela upende yezinto ze-TPU nayo inomsebenzi wokuziphilisa. Ngemva kokuklwebheka kancane, izinto zayo zingakwazi ukuzilungisa endaweni efudumele efanele, okuvumela umzimba ukuthi ululame njengakuqala futhi kwandise impilo yefilimu yokuvikela upende.
Le filimu yokuvikela upende yezinto ze-TPU ayigcini nje ngokuhlinzeka ngokuvikelwa okuphelele, kodwa futhi igcizelela kakhulu ukuvikelwa kwemvelo. Ifilimu yokuvikela upende eyenziwe ngezinto ezinobungani nemvelo ngeke ibangele noma yimuphi umthwalo emvelweni, okuhambisana nokuphishekela ukuhamba okuluhlaza ngabantu banamuhla.
Ukwethulwa kwefilimu yokuvikela upende wezinto ze-TPU kuphawula inguquko emkhakheni wokuvikela izimoto, okunikeza izixazululo zokuvikela ezithuthukisiwe nezithembekile kubanikazi bezimoto. Yamukela ukuvikelwa okuluhlaza, vumela izimoto zethu nomhlaba kuphefumule ndawonye.
Sicela uskene ikhodi ye-QR engenhla ukuze usithinte ngqo.
