Yintoni inzuzo yeTPU kunye nentambo yePUR?

I-TPU imfutshane kwigama layo lesiNgesi (i-Thermoplastic polyurethanes), kwaye igama layo lesiTshayina yirabha ye-Thermoplastic polyurethane elastomer.Luhlobo lwekhompawundi ye-polymer, izinto ze-TPU zibonakaliswa kukunganyangeki, ukuqina okuhle, amandla omatshini aphezulu, ukusebenza kakuhle kokusebenza, ukumelana nobushushu obuphezulu, ukuxhathisa okulungileyo kwamanzi.I-polyurethane imathiriyeli, ekwabizwa ngokuba yi-polyurethane, ikwaluhlobo olutsha lwe-polymer compound material, idla ngokusetyenziswa kwishishini lokulungisa, ikwabizwa ngokuba "yiplastiki yesihlanu", isifinyezo segama lesiNgesi yi-PUR.Okwangoku, izinto eziphathekayo zisetyenziswa ngokubanzi, ngakumbi abavelisi bekhebula.I-Wenchang ivelisa intambo ezininzi ze-TPU, siya kwazisa ukusetyenziswa kwentambo ye-TPU ye-polyurethane kushishino.

Okokuqala, ukushisa okuphezulu

I-TPU ephezulu ekwazi ukumelana nobushushu obuphezulu kunye nokumelana ne-oxidation: izixhobo zeplastiki eziqhelekileyo zilula ukuba zifakwe kwi-oxidized kwindawo engaphezulu kwe-70 ℃, i-TPU inokumelana ne-oxidation elungileyo;Ngokubanzi, ukuxhathisa ubushushu be-TPU kunokufikelela kwi-120 ℃.I-PUR yokumelana nokunxiba okuphezulu: ngaphezulu kwezigidi ezingama-20 zekhebula eliphezulu lokuguquguquka, ngaphezu kwezigidi ezingama-50 zekhebula eliphezulu lokuguquguquka liya kusebenzisa i-PUR, kuba inokumelana nokugoba okungcono, ukuxhathisa ukunxiba.

Okwesibini, ukumelana nobushushu obuphantsi

Ukumelana nokushisa okuphantsi kwe-TPU kunye ne-PUR lukhetho lokuqala lwezinto ezidumileyo kwintsimi ye-aviation.Inethemba elibanzi lesicelo kwintsimi ye-aerospace, kuba i-TPU kunye ne-PUR intambo yerobhothi inokumelana nokubanda okubalaseleyo kunye nokuzinza kokuhambisa kwiqondo lokushisa eliphantsi kungcono kunezinye izinto.

Okwesithathu, ukuxhathisa kweoli kunye nokutywinwa kobushushu obulula

I-TPU enetyhefu engenavumba kunye ne-PUR i-oyile ekwazi ukumelana nobushushu, akukho vumba, izinto ezingenayo ityhefu, le yi-TPU kunye ne-PUR inokuduma kwimarike, kuba izinto eziphathekayo ziyakwazi ukumelana neoli, ukunxiba, ukumelana nobushushu obuphezulu, ubushushu obuhle obuphantsi. ukumelana, ukuqina okulungileyo, kwaye akukho tyhefu kwaye akukho vumba elikhethekileyo kwimveliso yemveliso kunye neenjongo zokuvelisa likhulu kakhulu, ngoko ke khetha ngokubanzi imboni yentambo yoshishino lokuvelisa umatshini, Isetyenziswa ngokubanzi kwiingalo zerobhothi kunye namanye amalunga ahambayo, le ntambo inomsebenzi ofunekayo. .
