TPU ifilimu, njengento ephezulu yokusebenza kwepolymer, idlala indima ebalulekileyo kwiinkalo ezininzi ngenxa yeempawu zayo ezizodwa kunye neekhemikhali. Eli nqaku liza
zijule kwimathiriyeli yokwakheka, iinkqubo zemveliso, iimpawu, kunye nokusetyenziswa kweTPU ifilimu, kukuthatha uhambo lokuxabisa umtsalane wezobuchwepheshe wale nto.
1. Izinto zokwenziwa kwefilimu yeTPU:
Ifilimu ye-TPU, ekwabizwa ngokuba yifilimu ye-thermoplastic polyurethane, yifilim ebhityileyo eyenziwe nge-polyurethane njenge-substrate ngokusebenzisa iindlela ezithile zokusetyenzwa. Polyurethane yi
i-polymer eveliswa kukusabela kwee-polyols kunye ne-isocyanates, enokumelana okugqwesileyo kokunxiba, ukuqina, kunye nokumelana neekhemikhali. Ukuze kuphuculwe ukusebenza kwayo,
izongezo ezisebenzayo ezifana ne-antioxidants kunye ne-UV absorbers nazo zongezwa ngexesha lokwenziwa kweefilimu ze-TPU.
2. Inkqubo yokuvelisa:
Inkqubo yemveliso yeTPU ifilimuilungile kwaye intsonkothile, ingakumbi ibandakanya la manyathelo alandelayo:
Ukusabela kokudityaniswa: Okokuqala, phantsi kwentshukumo ye-catalyst, iipolyols kunye ne-isocyanates zifumana i-polymerization reaction ukwenza i-polyurethane prepolymers.
Nyibilikisa i-extrusion: Fudumeza i-prepolymer kwindawo etyhidiweyo kwaye emva koko uyikhuphele kwifilimu ngentloko ye-extruder.
Ukupholisa kunye nokubunjwa: Ifilimu etyhidiweyo etyhidiweyo ekhutshiweyo ipholiswa ngokukhawuleza ngerola yokupholisa ukuze iqine kwaye ifake.
Ukusetyenzwa kweposi: kubandakanya ukusika, ukujija kunye namanye amanyathelo, ukuze ekugqibeleni ufumane ifilimu yeTPU egqityiweyo.
3. Iimpawu:
Iimpawu zefilimu ye-TPU zisisiseko sosetyenziso lwayo olubanzi, olubonakaliswa ikakhulu kule miba ilandelayo:
Amandla aphezulu kunye nokunwebeka: Ifilimu ye-TPU inamandla aphezulu okuqina kunye nekhono elihle lokubuyisela i-elastic, kwaye inokumelana namandla amakhulu angaphandle ngaphandle kokuguqulwa.
Ukumelana nokunxiba: Ubunzima bomphezulu buphakathi, kunye nokumelana nokunxiba kakuhle, kufanelekile kwiindawo ezahlukeneyo ezinzima.
Ukumelana nobushushu: iyakwazi ukugcina uzinzo ngaphakathi koluhlu lobushushu ukusuka -40 ℃ ukuya kwi-120 ℃.
Ukumelana neekhemikhali: Iyakwazi ukumelana neekhemikhali ezininzi kwaye ayidleki lula.
Ukungena kokufuma: Unomlinganiselo othile wokungena kokufuma kwaye unokusetyenziswa kwiimeko apho kufuneka ukuphefumla.
4, Isicelo
Ngenxa yokusebenza kwayo kakuhle, ifilimu yeTPU isetyenziswe ngokubanzi kwiinkalo ezahlukeneyo, kubandakanya kodwa kungaphelelanga apho:
Umzi-mveliso wempahla: Njengelaphu lempahla, inika umaleko okhuselayo okhaphukhaphu, ongenamanzi, nophefumlayo.
Indawo yezonyango: Izinto zangaphandle ezifana neengubo zotyando, iimpahla ezikhuselayo, njl.njl. zisetyenziselwa ukwenza izixhobo zonyango.
Izixhobo zemidlalo: ezisetyenziselwa ukwenza izihlangu zemidlalo, iibhegi, kunye nezinye izixhobo zemidlalo, zibonelela ngokuzinzileyo kunye nentuthuzelo.
Umzi-mveliso weemoto: Njengempahla yokuhombisa yangaphakathi, inokuphucula intuthuzelo kunye ne-aesthetics yendawo yemoto.
Intsimi yokwakha: isetyenziselwa izinto zophahla, iileyiti ezingenamanzi, njl., Ukuphucula ukuxhathisa kwemozulu kunye nokusebenza kwamandla kwezakhiwo.
Ukushwankathela, njengemathiriyeli enemisebenzi emininzi, ifilimu yeTPU isetyenziswa kakhulu kuluntu lwanamhlanje. Izinto zayo zokubunjwa zizodwa, iinkqubo zokuvelisa
Inkqubela phambili, kunye neempawu zemveliso zahlukene. Ifilimu ye-TPU, enezinto zayo eziluncedo ezizodwa, ibonise ixabiso elingenakuphinda libuyiselwe kubomi bemihla ngemihla nakumacandelo obuchwepheshe obuphezulu.
