I-polyurethane ye-thermoplastic (TPU)sisixhobo esisebenza kakuhle esinokuguqula ukusetyenziswa kwelaphu ukusuka kwimisonto elukiweyo, amalaphu angangeni manzi, kunye namalaphu angalukwanga ukuya kwisikhumba esenziweyo. I-TPU esebenza ngeendlela ezininzi ikwahlala ixesha elide, inencasa ekhululekileyo, ihlala ixesha elide, kunye noluhlu lwemilo kunye nobunzima.
Okokuqala, iimveliso zethu zochungechunge lwe-TPU zinokuqina okuphezulu, ukuqina, kunye nokumelana nokuguguleka, oko kuthetha ukuba amalaphu anokusetyenziswa kwakhona ngaphandle kokuguqulwa. Ukumelana neoyile, ukumelana neekhemikhali, kunye nokumelana ne-UV kwenza i-TPU ibe yinto yendalo ekhethwayo yokusetyenziswa ngaphandle.
Ukongeza, ngenxa yokuba izinto ezisetyenziswayo ziyahambelana ne-biocompatibility, ukuphefumla kakuhle, kunye neempawu zokufunxa umswakama, abantu abazinxibayo bakhetha ukukhetha amalaphu alula e-polyurethane (PU) anokuchukumisa kamnandi kwaye omileyo.
Impilo yezinto ezisetyenzisiweyo inokwandiswa ifikelele kwinto yokuba i-TPU ingasetyenziswa kwakhona ngokupheleleyo, kunye neenkcukacha eziqala kokuthambileyo kakhulu ukuya kokuqinileyo kakhulu. Xa kuthelekiswa nezinye iindlela, esi sisisombululo sezinto esinye esizinzileyo. Ikwanazo neenkcukacha zomxholo we-low volatile organic compound (VOC) eziqinisekisiweyo, ezinokunciphisa ukukhutshwa komoya okuyingozi.
I-TPU inokulungiswa ukuze ibe neempawu ezithile ezifana nokuthintela amanzi okanye ukumelana neekhemikhali zoshishino. Ngokuchanekileyo, le nto ingalungiswa ngeendlela ezithile zokucubungula, ukusuka ekulukeni intambo ukuya ekubumbeni, ekukhupheni, nasekuprinteni nge-3D, ngaloo ndlela kube lula uyilo oluntsonkothileyo kunye nemveliso. Nazi ezinye iindlela ezithile i-TPU ephumelela kuzo.
Isicelo: Imisebenzi emininzi, ukusebenza okuphezuluIntambo yeTPU
I-TPU inokwenziwa ibe yimisonto yefilament enamacandelo amabini okanye amacandelo amabini, kwaye izisombululo zeekhemikhali zisetyenziswa phantse kuzo zonke iimeko (96%). Ukudaya okungemanzi kunokunciphisa impembelelo yokusingqongileyo kwiinkqubo zemveliso. Ngokwahlukileyo koko, xa kujikeleziswa i-melt, izisombululo azisetyenziswa rhoqo, ngoko ke ezi zisombululo zine-VOC ekhutshwayo ephantsi okanye engekhoyo. Ukongeza, ukujikeleziswa kwe-melt kunemvakalelo yesikhumba ethambileyo.
Isicelo: Izinto zelaphu ezingangeni manzi zeTPU, ezisetyenziselwa izigqubuthelo zelori, iingxowa zebhayisekile, kunye nolusu oluyilwe ngokwenziwa
I-TPU ayingeni manzi kwaye ayifuni mabala. Xa idibene nobomi bayo obude, iteknoloji ye-TPU lukhetho olufanelekileyo kwiindlela ezinzima ezifana namalaphu angangeni manzi elori, iibhegi zebhayisekile, kunye nolusu oluyilwe ngokwenziwa. Enye inzuzo ebalulekileyo kukuba i-polyurethane ye-thermoplastic kulula ukuyiphinda isetyenziswe kunezinye izinto ezininzi zelaphu ezingangeni manzi ezikhoyo.
Akukho zisombululo zeekhemikhali ezisetyenziswa kwiinkqubo ze-thermoplastic ezifana ne-rolling okanye i-T-die extrusion ukuqinisekisa ukunciphisa okanye ukuphelisa ngokupheleleyo ii-VOC. Kwangaxeshanye, akukho mfuneko yokusebenzisa amanzi ukuhlamba iikhemikhali ezigqithisileyo, nto leyo eyinxalenye eqhelekileyo yonyango lwesisombululo.
Isicelo: Isikhumba esenziwe ngeTPU esihlala ixesha elide nesinokuphinde sisetyenziswe
Inkangeleko kunye nemvakalelo yesikhumba esenziweyo kunzima ukwahlula kwesikhumba sendalo, kwaye kwangaxeshanye, imveliso ineenketho ezingenamkhawulo zombala kunye nokuthungwa komphezulu, kunye nokumelana neoyile yendalo ye-TPU, ukumelana negrisi, kunye nokumelana nokuguguleka. Ngenxa yokungabikho kwezixhobo eziluhlaza ezivela kwizilwanyana, isikhumba esenziweyo se-TPU sikwafanelekile kakhulu kubantu abatya imifuno. Ekupheleni kwesigaba sokusetyenziswa, isikhumba esenziweyo esisekelwe kwi-PU sinokuphinda sisetyenziswe ngoomatshini.
Isicelo: Ilaphu elingalukwanga
Eyona nto ikhethekileyo ethengiswa ngayo ilaphu elingalukwanga le-TPU kukuchukumisa kwalo okukhululekileyo nokuthambileyo, kunye nokukwazi ukugoba, ukulula, kunye nokuguquguquka ngokuphindaphindiweyo kumanqanaba obushushu ahlukeneyo ngaphandle kokuqhekeka.
Ifanelekile ngokukodwa kwiimpahla zemidlalo nezesinxibo esiqhelekileyo, apho imicu yelastiki inokuhlanganiswa kwisakhiwo se-mesh esiphefumla lula, okwenza kube lula ukuba umoya ungene kwaye ukhuphe ukubila.
Imemori yesimo ingayilwa ibe yilaphu le-TPU polyester elingalukwanga, eliqondo lokunyibilika eliphantsi lithetha ukuba lingacinezelwa ngobushushu kwamanye amalaphu. Izinto ezahlukeneyo ezinokuphinda zisetyenziswe, ezisekelwe kwi-bio ethile, kunye nezinto ezingaguqukiyo zingasetyenziselwa amalaphu angalukwanga.
