Ifilimu yeTPU, njengesixhobo sepolymer esisebenza kakuhle, sidlala indima ebalulekileyo kwiindawo ezininzi ngenxa yeempawu zaso zomzimba nezekhemikhali ezikhethekileyo. Eli nqaku liza
funda ngezinto zokwakha, iinkqubo zemveliso, iimpawu kunye nokusetyenziswa kwazoIfilimu yeTPU, ikusa kuhambo lokuxabisa ubuhle betekhnoloji bale nto.
1. Izixhobo zokwakheka kwefilimu yeTPU:
Ifilimu yeTPU, ekwaziwa ngokuba yifilimu ye-thermoplastic polyurethane, yifilimu encinci eyenziwe nge-polyurethane njengesiseko ngokusebenzisa iindlela ezithile zokucubungula.
i-polymer eveliswa yimpendulo ye-polyols kunye ne-isocyanates, enokumelana nokuguguleka okuhle kakhulu, ukuthamba, kunye nokumelana neekhemikhali. Ukuze kuphuculwe ukusebenza kwayo,
Izongezo ezisebenzayo ezifana nee-antioxidants kunye nee-UV absorbers nazo zongezwa ngexesha lokwenziwa kweefilimu ze-TPU.
2. Inkqubo yemveliso:
Inkqubo yemvelisoIfilimu yeTPUilungile kwaye iyinkimbinkimbi, ikakhulu ibandakanya la manyathelo alandelayo:
Impendulo yokuhlanganisa: Okokuqala, phantsi kwesenzo se-catalyst, ii-polyols kunye nee-isocyanates zenza i-polymerization reaction ukuze zenze i-polyurethane prepolymers.
Ukunyibilikisa i-extrusion: Fudumeza i-prepolymer ibe yimo enyibilikisiweyo uze uyikhuphe ibe yifilimu ngentloko ye-extruder.
Ukupholisa nokubumba: Ifilimu enyibilikisiweyo ekhutshiweyo ipholiswa ngokukhawuleza ngerola yokupholisa ukuze iqine kwaye ibumbeke.
Ukucubungula emva: kuquka ukusika, ukujija kunye namanye amanyathelo, ukuze ekugqibeleni ufumane ifilimu yeTPU egqityiweyo.
3. Iimpawu:
Iimpawu zefilimu yeTPU zisisiseko sokusetyenziswa kwayo ngokubanzi, ikakhulu zibonakaliswa kwezi zinto zilandelayo:
Amandla aphezulu kunye nokuthamba: Ifilimu ye-TPU inamandla aphezulu okutsalwa kunye nokukwazi ukubuyisela ukuthamba kakuhle, kwaye inokumelana namandla amakhulu angaphandle ngaphandle kokuguquka.
Ukumelana nokuguguleka: Ubulukhuni bomphezulu buphakathi, bunokumelana nokuguguleka okuhle, bufanelekile kwiindawo ezahlukeneyo ezinzima.
Ukumelana nobushushu: iyakwazi ukugcina uzinzo ngaphakathi koluhlu lobushushu oluqala kwi -40 ℃ ukuya kwi-120 ℃.
Ukumelana neekhemikhali: Iyakwazi ukumelana neekhemikhali ezininzi kwaye ayidli mhlwa lula.
Ukufuma: Inomlinganiselo othile wokufuma kwaye ingasetyenziswa kwiimeko apho kufuneka ukuphefumla.
4, Isicelo
Ngenxa yokusebenza kwayo okugqwesileyo, ifilimu yeTPU isetyenziswa kakhulu kwiindawo ezahlukeneyo, kuquka kodwa kungaphelelanga apho:
Ishishini lempahla: Njengelaphu lempahla, libonelela ngomaleko wokukhusela okhaphukhaphu, ongangeni manzi, nonokuphefumla.
Icandelo lezonyango: Izixhobo zangaphandle ezifana neengubo zotyando, impahla yokuzikhusela, njl.njl. zisetyenziselwa ukwenza izixhobo zonyango.
Izixhobo zemidlalo: ezisetyenziselwa ukwenza izihlangu zemidlalo, iingxowa, kunye nezinye izixhobo zemidlalo, ezibonelela ngokuqina kunye nentuthuzelo.
Ishishini leemoto: Njengezinto zokuhombisa ngaphakathi, inokuphucula intuthuzelo kunye nobuhle bendawo yemoto.
Intsimi yokwakha: isetyenziselwa izinto zophahla, iileya ezingangeni manzi, njl.njl., ukuphucula ukumelana nemozulu kunye nokusebenza kakuhle kwamandla kwezakhiwo.
Ngamafutshane, njengesixhobo esinezinto ezininzi, ifilimu yeTPU isetyenziswa kakhulu kuluntu lwanamhlanje. Izixhobo zayo zokwenziwa zihlukile, iinkqubo zemveliso.
ziyaqhubeka, kwaye iimpawu zemveliso zahlukile. Ifilimu yeTPU, kunye neenzuzo zayo ezikhethekileyo, ibonakalise ixabiso elingenakutshintshwa kubomi bemihla ngemihla nakwiinkalo zobuchwepheshe obuphezulu.
