I-TPU sisifinyezo segama layo lesiNgesi (ii-polyurethanes zeThermoplastic), kwaye igama layo lesiTshayina yi-Thermoplastic polyurethane elastomer rubber. Luhlobo lwe-polymer compound, izinto ze-TPU zibonakaliswa kukumelana nokuguguleka, ukuthamba okuhle, amandla aphezulu oomatshini, ukusebenza kakuhle kokucubungula, ukumelana nobushushu obuphezulu, ukumelana kakuhle namanzi. Izinto zePolyurethane, ezaziwa ngokuba yi-polyurethane, zikwaluhlobo olutsha lwezinto ze-polymer compound, zisetyenziswa kakhulu kushishino lokucubungula, zikwaziwa ngokuba yi-"fifth plastic", isifinyezo segama lesiNgesi yi-PUR. Okwangoku, ezi zinto zisetyenziswa kakhulu, ingakumbi abavelisi beentambo. I-Wenchang ivelisa iintambo ezininzi ze-TPU, siza kwazisa ukusetyenziswa kwentambo ye-TPU polyurethane kushishino.
Okokuqala, ubushushu obuphezulu
Ukumelana nobushushu obuphezulu beTPU kunye nokuxhathisa i-oxidation: izinto zeplastiki eziqhelekileyo kulula ukuzinyibilikisa kwindawo engaphezulu kwe-70℃ ixesha elide, i-TPU inokumelana okuhle kwe-oxidation; Ngokubanzi, ukumelana nobushushu be-TPU kunokufikelela kwi-120℃. Ukumelana nokuguguleka okukhulu kwe-PUR: ngaphezulu kwe-20 yezigidi zeentambo ezigugulekayo, ngaphezulu kwe-50 yezigidi zeentambo ezigugulekayo ziya kusebenzisa i-PUR, kuba inokumelana okungcono kokugoba, ukumelana nokuguguleka.
Okwesibini, ukumelana nobushushu obuphantsi
Ukumelana nobushushu obuphantsi kweTPU kunye nePUR lukhetho lokuqala lwezixhobo ezidumileyo kwicandelo leenqwelo moya. Inethuba elikhulu lokusetyenziswa kwicandelo leenqwelo moya, kuba intambo yerobhothi yeTPU kunye nePUR inokumelana nokubanda okubalaseleyo kwaye uzinzo lokudlulisela kubushushu obuphantsi lungcono kunezinye izixhobo.
Okwesithathu, ukumelana neoyile kunye nokutywinwa kobushushu okulula
I-TPU kunye ne-PUR ezingenavumba azinatyhefu zitywina ubushushu ezingatshiyo kwioyile, azinavumba, azinatyhefu, le yi-TPU kwaye i-PUR inokuthandwa kwimarike, kuba le nto ayitshiyo kwioyile, ayitshiyo, ayitshiyo kwiqondo lobushushu eliphezulu, ayitshiyo kwiqondo lobushushu eliphantsi, ayitshiyo kwaye ayinatyhefu kwaye ayinavumba lingaqhelekanga kwimveliso yemizi-mveliso kunye neenjongo zokuvelisa inkulu kakhulu, ngoko ke ngokubanzi khetha ishishini leentambo kushishino lokuvelisa oomatshini, Isetyenziswa kakhulu kwiingalo zerobhothi kunye nezinye iindawo ezishukumayo, le ntambo inokusebenza okufunekayo.
