Iinkcukacha kunye nezicelo zoShishinoTPU izinto ekrwadakuba iifilimu zisetyenziswa kakhulu kumashishini ahlukeneyo ngenxa yokusebenza kwawo okugqwesileyo. Oku kulandelayo yingcaciso yesiNgesi – intshayelelo yolwimi: 1. Ulwazi oluSisiseko I-TPU sisishunqulelo se-thermoplastic polyurethane, ekwaziwa njenge-thermoplastic polyurethane elastomer. Izinto ze-TPU ekrwada zeefilim zihlala zenziwe ngepolymerizing izinto ezintathu eziphambili ekrwada: iipolyols, diisocyanates, kunye nechain extender. IiPolyols zibonelela ngecandelo elithambileyo le-TPU, liyinika ukuguquguquka kunye nokunwebeka. I-Diisocyanates isabela nge-polyols ukwenza icandelo elinzima, elinegalelo kumandla kunye nokuqina kwe-TPU. Izandiso zekhonkco zisetyenziselwa ukwandisa ubunzima bemolekyuli kunye nokuphucula iimpawu zemishini ye-TPU. 2. Iifilimu ze-TPU zeNkqubo yeMveliso zenziwe kwizinto ze-TPU zegranular ngokusebenzisa iinkqubo ezifana ne-calendering, ukuphosa, ukuvuthela, kunye nokugqoka. Phakathi kwabo, ukunyibilika - inkqubo ye-extrusion yindlela eqhelekileyo. Okokuqala, i-polyurethane ixutywa kunye nezinto ezahlukeneyo zokudibanisa, ezifana neeplastiki zokuphucula ukuguquguquka, iziqinisekiso zokuphucula ubushushu kunye nokumelana nokukhanya, kunye ne-pigments yokwenza imibala. Emva koko, ishushu kwaye iyancibilika, kwaye ekugqibeleni inyanzeliswe ngokufa ukuze yenze ifilimu eqhubekayo, epholileyo kwaye inxeba ibe ngumqulu. Inkqubo yokupholisa ibalulekile njengoko ichaphazela i-crystallization kunye nokuqhelaniswa kwee-molecule ze-TPU, ngaloo ndlela ibe nefuthe kwiipropati zokugqibela zefilimu. 3. Iimpawu zeNtsebenzo 3.1 Iimpawu zePhysical Properties Iifilimu ze-TPU zinokuguquguquka okugqwesileyo kunye no-elasticity, kwaye zinokolulwa kwaye zikhubazeke kwinqanaba elithile, kwaye zinokubuyela kwisimo sazo sangaphambili ngaphandle kokuguqulwa, okufanelekileyo kwiimeko ezifuna ukugoba rhoqo kunye nokujija. Umzekelo, kwimveliso ye-elektroniki eguquguqukayo, iifilimu ze-TPU zinokuhambelana nendawo egobileyo yezixhobo. Kwangaxeshanye, ikwanawo amandla aphezulu kunye nokukrazula - amandla okumelana, anokumelana ngempumelelo nempembelelo yangaphandle kunye nomonakalo. Oku kwenza iifilimu ze-TPU zilungele ukusetyenziswa kwipakethe yokukhusela, apho kufuneka imelane nokuphathwa kakubi. I-3.2 Iimpahla zeMichiza Iifilimu ze-TPU zinokumelana nokubola kweekhemikhali, kwaye zinokunyamezela okuthile kwii-acids eziqhelekileyo, i-alkali, i-solvents, njl., kwaye akulula ukuba i-corrod. Ngokukodwa, ukuxhathisa kwe-hydrolysis ye-polyether - uhlobo lweefilimu ze-TPU zivumela ukuba zigcine ukusebenza okuzinzile emanzini - kwiindawo ezityebileyo. Le propati ibenza balungele ukusetyenziswa kwizicelo ezifana neengubo ezingaphantsi kwamanzi kunye neembrane ezingenamanzi. 3.3 Ukuxhathisa iMozuluIifilimu zeTPUinokugcina ukusebenza okuzinzileyo kwiindawo ezahlukeneyo zokushisa. Akulula ukuba zibe lukhuni kwaye zibe brittle kwiindawo ezisezantsi zobushushu, kwaye azikho lula ukuthamba kunye nokonakala kwiindawo eziphezulu zobushushu. Baphinde babe nekhono elithile lokumelana nemitha ye-ultraviolet, kwaye akulula ukuguga kunye nokucima phantsi kokukhanya kwexesha elide. Oku kwenza ukuba iifilimu ze-TPU zilungele usetyenziso lwangaphandle, olufana ne-auto trim yangaphandle kunye nefenitshala yangaphandle. 4. IiNdlela eziPhambili zokuLungisa Iindlela eziphambili zokusetyenzwa kweIifilimu zeTPUziquka ukuvuthela - ukubumba, ukuphosa, kunye nekhalenda. Ngokuvuthela - ukubumba, iifilimu zeTPU ezinobunzima obahlukeneyo kunye nobubanzi zinokuveliswa ngokufaka umoya ityhubhu yeTPU etyhidiweyo. Ukugalela kubandakanya ukugalela ukwenziwa kwe-TPU elulwelo kumphezulu osicaba kwaye uyivumele ukuba iqine. ICalender isebenzisa iirola ukucofa kunye nokubumba iTPU ibe yifilimu yobukhulu obufunwayo. Ezi ndlela zinokuvelisa iifilimu ze-TPU ezinobunzima obahlukeneyo, ububanzi, kunye nemibala ukuhlangabezana neemfuno zeemeko ezahlukeneyo zesicelo. Umzekelo, iifilimu ze-TPU ezincinci nezicacileyo zihlala zisetyenziselwa ukupakisha, ngelixa iifilimu ezishinyeneyo nezinemibala zinokusetyenziselwa ukuhombisa. 5. IiFilimu ze-Application Fields ze-TPU zinokudibaniswa kunye neentlobo zeendwangu zokwenza izicathulo - iingubo eziphezulu kunye nemisebenzi engenamanzi kunye nokuphefumula, okanye iingubo zokuhlobisa, ezisetyenziswa kakhulu kwiingubo eziqhelekileyo, iimpahla zelanga, iingubo zangaphantsi, i-raincoats, i-windbreakers, i-T - shirts, i-sportswear kunye nezinye iingubo. Kwicandelo lezonyango,Iifilimu zeTPUzisetyenziswa kwizicelo ezifana nokunxitywa kwamanxeba kunye neengubo zokwaleka zesixhobo sonyango ngenxa yokuhambelana kwazo nezinto eziphilayo. Ukongeza, i-TPU iye yasetyenziswa ngokubanzi kwizixhobo zezihlangu, iithoyi ezinokuphephetheka, izixhobo zemidlalo, izixhobo zokuhlala zemoto, iiambrela, iisutikheyisi, iibhegi kunye namanye amabala. Ngokomzekelo, kwizixhobo zemidlalo, iifilimu ze-TPU zisetyenziselwa ukwenza iipads zokukhusela kunye nokubamba, ukubonelela kokubili ukuthuthuzela kunye nokuqina.
