Iyini inzuzo yentambo ye-TPU ne-PUR?

I-TPU imfushane egameni layo lesiNgisi (Thermoplastic polyurethanes), futhi igama layo lesiShayina yirabha ye-Thermoplastic polyurethane elastomer.Iwuhlobo lwenhlanganisela ye-polymer, impahla ye-TPU ibonakala ngokumelana nokugqoka, ukunwebeka okuhle, amandla aphezulu emishini, ukusebenza kahle kokucubungula, ukumelana nokushisa okuphezulu, ukumelana kahle kwamanzi.I-polyurethane impahla, eyaziwa nangokuthi i-polyurethane, iphinde ibe uhlobo olusha lwezinto ezihlanganisiwe ze-polymer, ivame ukusetshenziswa embonini yokucubungula, yaziwa nangokuthi "ipulasitiki yesihlanu", Isifinyezo segama lesiNgisi i-PUR.Njengamanje, impahla isetshenziswa kabanzi, ikakhulukazi abakhiqizi bekhebula.I-Wenchang ikhiqiza izintambo eziningi ze-TPU, sizokwethula ukusetshenziswa kwentambo ye-TPU polyurethane embonini.

Okokuqala, izinga lokushisa eliphezulu

I-TPU ephakeme ukumelana nokushisa okuphezulu nokumelana ne-oxidation: izinto zokusetshenziswa zepulasitiki ezijwayelekile kulula ukuba zenziwe nge-oxidized endaweni engaphezu kuka-70 ℃ isikhathi eside, i-TPU inokumelana okuhle kwe-oxidation;Ngokuvamile, ukumelana nezinga lokushisa kwe-TPU kungafinyelela ku-120 ℃.I-PUR super wear resistance: izikhathi ezingaphezu kwezigidi ezingu-20 zekhebula eliphezulu eliguquguqukayo, izikhathi ezingaphezu kwezigidi ezingu-50 zekhebula eliphezulu eliguquguqukayo zizosebenzisa i-PUR, ngoba inokumelana nokugoba okungcono, ukumelana nokugqoka.

Okwesibili, ukumelana nokushisa okuphansi

Ukumelana nokushisa okuphansi kwe-TPU ne-PUR ukukhetha kokuqala kwezinto ezithandwayo emkhakheni wezindiza.Inethuba elibanzi lohlelo lokusebenza emkhakheni we-aerospace, ngoba intambo yerobhothi ye-TPU ne-PUR inokumelana nokubanda okuvelele kanye nokuzinza kokudlulisela ekushiseni okuphansi kungcono kunezinye izinto.

Okwesithathu, ukumelana nowoyela kanye nokuvala ukushisa kalula

I-TPU ne-PUR engenaphunga engenabuthi ivala uwoyela ukumelana nokushisa, akukho phunga, izinto ezingezona ezinobuthi, le yi-TPU ne-PUR ingaduma emakethe, ngoba izinto ezisetshenziswayo azikwazi ukumelana nowoyela, ziyakwazi ukugqokwa, ukumelana nokushisa okuphezulu, izinga lokushisa elihle eliphansi. ukumelana, ukunwebeka okuhle, futhi akukho ushevu futhi akukho phunga elingavamile ekukhiqizeni izimboni kanye nezinjongo zokukhiqiza kukhulu kakhulu, ngakho ngokuvamile khetha imboni yamakhebula imboni yokukhiqiza umshini, Isetshenziswa kakhulu ezingalweni zamarobhothi namanye amalunga anyakazayo, le ntambo inokusebenza okudingekayo. .
