Imfihlakalo yefilimu ye-TPU: ukwakheka, inqubo kanye nokuhlaziywa kwesicelo

Ifilimu ye-TPU, njengento ye-polymer esebenza kahle kakhulu, idlala indima ebalulekile emikhakheni eminingi ngenxa yezakhiwo zayo eziyingqayizivele zomzimba nezamakhemikhali. Lesi sihloko sizo

funda ngezinto zokwakha, izinqubo zokukhiqiza, izici, kanye nokusetshenziswa kwazoIfilimu ye-TPU, ikuyisa ohambweni lokwazisa ubuhle bezobuchwepheshe balezi zinto.

1. Izinto zokwakha zefilimu ye-TPU:

Ifilimu ye-TPU, eyaziwa nangokuthi ifilimu ye-thermoplastic polyurethane, iwuhlobo lwefilimu oluncane olwenziwe nge-polyurethane njengesisekelo ngokusebenzisa amasu athile okucubungula. I-Polyurethane iyi-

i-polymer ekhiqizwa ukusabela kwama-polyol nama-isocyanates, anokumelana okuhle kakhulu nokuguguleka, ukuguquguquka, kanye nokumelana namakhemikhali. Ukuze kuthuthukiswe ukusebenza kwayo,

Izithasiselo ezisebenzayo ezifana nama-antioxidants kanye nama-UV absorber nazo zengezwa ngesikhathi sokwenziwa kwamafilimu e-TPU.

2. Inqubo yokukhiqiza:

Inqubo yokukhiqizaIfilimu ye-TPUkulungile futhi kuyinkimbinkimbi, ikakhulukazi okuhlanganisa izinyathelo ezilandelayo:

Ukusabela kokuhlanganisa: Okokuqala, ngaphansi kwesenzo se-catalyst, ama-polyol nama-isocyanates abhekana nokusabela kwe-polymerization ukuze akhe ama-prepolymer e-polyurethane.

Ukuncibilikisa i-extrusion: Shisa i-prepolymer ibe sesimweni esincibilikisiwe bese uyikhipha ibe yifilimu ngekhanda le-extruder.

Ukupholisa nokubumba: Ifilimu encibilikisiwe ekhishwe ipholiswa ngokushesha nge-roller yokupholisa ukuze iqine futhi yakheke.

Ukucutshungulwa ngemuva: kufaka phakathi ukusika, ukugoqa kanye nezinye izinyathelo, ukuze ekugcineni kutholakale ifilimu ye-TPU eqediwe.

3. Izici:

Izici zefilimu ye-TPU ziyisisekelo sokusetshenziswa kwayo okubanzi, ikakhulukazi ezibonakala kulezi zici ezilandelayo:

Amandla aphezulu kanye nokunwebeka: Ifilimu ye-TPU inamandla aphezulu okudonseka kanye nekhono elihle lokululama lokunwebeka, futhi ingamelana namandla amakhulu angaphandle ngaphandle kokuguquka.

Ukumelana nokuguguleka: Ubulukhuni bomphezulu buphakathi nendawo, bunokumelana okuhle nokuguguleka, bufanelekela izindawo ezahlukahlukene ezinzima.

Ukumelana nokushisa: okukwazi ukugcina ukuqina ngaphakathi kobubanzi bokushisa obuphakathi kuka--40 ℃ kuya ku-120 ℃.

Ukumelana namakhemikhali: Iyakwazi ukumelana namakhemikhali amaningi futhi ayigugi kalula.

Ukuvunyelwa komswakama: Inezinga elithile lokuvunyelwa komswakama futhi ingasetshenziswa ezimweni lapho kudingeka khona ukuphefumula.

4, Isicelo

Ngenxa yokusebenza kwayo okuhle kakhulu, ifilimu ye-TPU isetshenziswe kabanzi emikhakheni ehlukahlukene, okuhlanganisa kodwa kungagcini lapho:

Imboni yezingubo: Njengendwangu yezingubo, inikeza ungqimba oluvikelayo olulula, olungangeni manzi, noluphefumulayo.

Insimu yezokwelapha: Izinto zangaphandle ezifana nezingubo zokuhlinzwa, izingubo zokuzivikela, njll. zisetshenziselwa ukwenza amadivayisi ezokwelapha.

Imishini yezemidlalo: isetshenziselwa ukukhiqiza izicathulo zezemidlalo, izikhwama, neminye imishini yezemidlalo, okunikeza ukuqina nenduduzo.

Imboni yezimoto: Njengezinto zokuhlobisa ingaphakathi, ingathuthukisa induduzo kanye nobuhle bendawo yemoto.

Insimu yokwakha: esetshenziselwa izinto zophahla, izendlalelo ezingangeni manzi, njll., ukuthuthukisa ukumelana nesimo sezulu kanye nokusebenza kahle kwamandla kwezakhiwo.

Ngamafuphi, njengezinto ezisebenza ngezindlela eziningi, ifilimu ye-TPU isetshenziswe kabanzi emphakathini wanamuhla. Izinto zayo zokwakheka zihlukile, izinqubo zokukhiqiza

ziyathuthuka, futhi izici zomkhiqizo ziyahlukahluka. Ifilimu ye-TPU, enezinzuzo zayo eziyingqayizivele, ibonise inani elingenakuphikwa kokubili empilweni yansuku zonke kanye nasemasimini obuchwepheshe obuphezulu.
