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

TPU ifilimu, njengento ephezulu yokusebenza kwe-polymer, idlala indima ebalulekile emikhakheni eminingi ngenxa yezakhiwo zayo eziyingqayizivele zomzimba namakhemikhali. Lesi sihloko sizokwenza

hlolisisa izinto zokwakha, izinqubo zokukhiqiza, izici, kanye nokusetshenziswa kweTPU ifilimu, kukuthatha ohambweni lokwazisa ubuhle bezobuchwepheshe bale nto.

1. Izinto zokwakha zefilimu ye-TPU:

Ifilimu ye-TPU, eyaziwa nangokuthi ifilimu ye-thermoplastic polyurethane, iyifilimu encane eyenziwe nge-polyurethane njenge-substrate ngokusebenzisa amasu athile okucubungula. I-polyurethane i-a

i-polymer ekhiqizwa ukusabela kwama-polyols nama-isocyanates, anokumelana okuhle kakhulu nokugqoka, ukunwebeka, nokumelana namakhemikhali. Ukuze kuthuthukiswe ukusebenza kwayo,

izithasiselo ezisebenzayo ezifana nama-antioxidant nama-absorbers we-UV nazo zengezwa ngesikhathi kukhiqizwa amafilimu e-TPU.

2. Inqubo yokukhiqiza:

Inqubo yokukhiqiza yeTPU ifilimukuhle futhi kuyinkimbinkimbi, ikakhulukazi kufaka phakathi izinyathelo ezilandelayo:

Ukusabela kokuhlanganisa: Okokuqala, ngaphansi kwesenzo se-catalyst, ama-polyols nama-isocyanate abhekana ne-polymerization ukuze akhe ama-prepolymers e-polyurethane.

Ncibilikisa i-extrusion: Shisisa i-prepolymer ibe yisimo esincibilikisiwe bese uyikhipha ibe yifilimu ngekhanda elikhiphayo.

Ukupholisa nokubunjwa: Ifilimu encibilikisiwe enwetshiwe ipholiswa ngokushesha ngerola yokupholisa ukuze iqine futhi yakheke.

Ukucubungula okuthunyelwe: okuhlanganisa ukusika, ukusonga nezinye izinyathelo, ukuze ekugcineni uthole ifilimu ye-TPU ephelile.

3. Izici:

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

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

Ukumelana nokugqoka: Ukuqina kobuso kumaphakathi, kunokumelana okuhle nokugqokwa, kulungele izindawo ezahlukahlukene ezinokhahlo.

Ukumelana nezinga lokushisa: ikwazi ukugcina ukuzinza ngaphakathi kwezinga lokushisa lika -40 ℃ kuya ku-120 ℃.

Ukumelana namakhemikhali: Inokumelana kahle namakhemikhali amaningi futhi ayigqwali kalula.

Ukungena komswakama: Inezinga elithile lokungena komswakama futhi ingasetshenziswa ezimeni lapho kudingeka khona ukuphefumula.

4. Isicelo

Ngenxa yokusebenza kwayo okuhle kakhulu, ifilimu ye-TPU isetshenziswe kabanzi emikhakheni ehlukahlukene, kufaka phakathi kodwa ingagcini nje:

Imboni yezingubo: Njengendwangu yezingubo, inikeza ungqimba oluvikelayo olungasindi, olungangeni manzi, nokuphefumulayo.

Inkundla yezokwelapha: Izinto zangaphandle ezifana nezingubo zokuhlinza, izingubo zokuzivikela, njll. zisetshenziselwa ukwenza izinto zokwelapha.

Izimpahla zezemidlalo: ezisetshenziselwa ukukhiqiza izicathulo zezemidlalo, izikhwama, nezinye izinto zezemidlalo, ezinikeza ukuqina nokunethezeka.

Imboni yezimoto: Njengempahla yokuhlobisa ingaphakathi, ingathuthukisa ukunethezeka nobuhle bendawo yemoto.

Inkundla yokwakha: isetshenziselwa izinto zophahla, izendlalelo ezingangeni manzi, njll., ukuthuthukisa ukumelana nesimo sezulu nokusebenza kahle kwamandla kwezakhiwo.

Ukufingqa, njengezinto ezisebenzayo eziningi, ifilimu ye-TPU isetshenziswe kabanzi emphakathini wanamuhla. Izinto zayo zokubunjwa zihlukile, izinqubo zokukhiqiza

ukuqhubekela phambili, nezici zomkhiqizo zihlukene. Ifilimu ye-TPU, enezinzuzo zayo eziyingqayizivele, ibonise inani elingenakushintshwa ekuphileni kwansuku zonke kanye nezinkambu zobuchwepheshe obuphezulu.
