Incazelo: I-TPU iyi-copolymer ye-block eqondile eyenziwe nge-diisocyanate equkethe iqembu elisebenzayo le-NCO kanye ne-polyether equkethe iqembu elisebenzayo le-OH, i-polyester polyol kanye ne-chain extender, ezikhishwa futhi zixutshwe.
Izici: I-TPU ihlanganisa izici zerabha nepulasitiki, ngokunwebeka okuphezulu, amandla aphezulu, ukumelana nokuguguleka okuphezulu, ukumelana namafutha, ukumelana namanzi, ukumelana nokushisa okuphansi, ukumelana nokuguga nezinye izinzuzo.
hlunga
Ngokwesakhiwo sengxenye ethambile, ingahlukaniswa ngohlobo lwe-polyester, uhlobo lwe-polyether kanye nohlobo lwe-butadiene, oluqukethe iqembu le-ester, iqembu le-ether noma iqembu le-butene ngokulandelana.I-TPUinamandla amahle okusebenza, ukumelana nokuguguleka kanye nokumelana namafutha.I-TPU ye-Polyetherinokumelana okungcono kwe-hydrolysis, ukumelana nokushisa okuphansi kanye nokuguquguquka.
Ngokwesakhiwo sesigaba esiqinile, singahlukaniswa ngohlobo lwe-aminoester kanye nohlobo lwe-aminoester urea, olutholakala ku-diol chain extender noma ku-diamine chain extender, ngokulandelana.
Ngokusho kokuthi kukhona yini ukuxhumanisa: kungahlukaniswa kube yi-thermoplastic emsulwa kanye ne-semi-thermoplastic. Eyokuqala iyisakhiwo esiqondile esimsulwa ngaphandle kokuxhumanisa. Eyokugcina iyisibopho esixhumene esiqukethe inani elincane lamafomethi e-urea.
Ngokusebenzisa imikhiqizo eqediwe, ingahlukaniswa ibe izingxenye ezibunjwe ngendlela ekhethekile (izingxenye ezahlukahlukene zemishini), amapayipi (amajakethi, amaphrofayili enduku) kanye namafilimu (amashidi, amashidi), kanye nezinamathiselo, izembozo kanye nemicu.
Ubuchwepheshe bokukhiqiza
Ukwenziwa kwe-polymerization ngobuningi: kungahlukaniswa futhi kube yindlela yangaphambi kokwenziwa kwe-polymerization kanye nendlela yesinyathelo esisodwa ngokuya ngokuthi kukhona yini ukusabela kwangaphambi kokwenziwa. Indlela yangaphambi kokwenziwa kwe-polymerization iwukwenza i-diisocyanate ne-macromolecule diol isikhathi esithile ngaphambi kokufaka i-chain extender ukukhiqiza i-TPU. Indlela yesinyathelo esisodwa ukuxuba i-macromolecule diol, i-diisocyanate kanye ne-chain extender ngesikhathi esifanayo ukukhiqiza i-TPU.
I-polymerization yesisombululo: i-diisocyanate iqale incibilike ku-solvent, bese kuba i-macromolecule diol engezwa ukuze isabele isikhathi esithile, bese ekugcineni i-chain extender ingezwa ukuze ikhiqizeI-TPU.
Inkambu yohlelo lokusebenza
Insimu yezinto zezicathulo: Ngenxa yokuthi i-TPU inokuguquguquka okuhle kakhulu kanye nokumelana nokuguguleka, ingathuthukisa induduzo nokuqina kwezicathulo, futhi ivame ukusetshenziswa ekuhlobiseni okungaphezulu, isikhwama somoya, umcamelo womoya kanye nezinye izingxenye zezicathulo zezemidlalo nezicathulo ezivamile.
Insimu Yezokwelapha: I-TPU ihambisana kahle kakhulu ne-biocompatibility, ayinabo ubuthi, ayibangeli ukungezwani komzimba nezinye izici, ingasetshenziswa ukukhiqiza ama-catheter ezokwelapha, izikhwama zezokwelapha, izitho zokwenziwa, imishini yokufaneleka komzimba nokunye.
Insimu Yezimoto: I-TPU ingasetshenziswa ukukhiqiza izinto zezihlalo zemoto, amaphaneli ezinsimbi, izembozo zesiteringi, izivalo, ipayipi likawoyela, njll., ukuze kuhlangatshezwane nezidingo zenduduzo, ukumelana nokuguguleka kanye nokumelana nesimo sezulu sangaphakathi kwezimoto, kanye nezidingo zokumelana namafutha kanye nokumelana nokushisa okuphezulu kwegumbi lenjini yezimoto.
Amasimu kagesi nawe-elekthronikhi: I-TPU inokumelana okuhle nokuguguleka, ukumelana nokuklwebheka kanye nokuguquguquka, futhi ingasetshenziswa ukukhiqiza ucingo kanye ne-cable sheath, ikesi lefoni ephathekayo, ikhava yokuvikela ikhompyutha yethebhulethi, ifilimu yekhibhodi njalo njalo.
Insimu Yezimboni: I-TPU ingasetshenziswa ukukhiqiza izingxenye ezahlukahlukene zemishini, amabhande okuhambisa, izivalo, amapayipi, amashidi, njll., ingamelana nengcindezi enkulu nokungqubuzana, kuyilapho inokumelana okuhle nokugqwala kanye nokumelana nesimo sezulu.
Insimu yezimpahla zemidlalo: esetshenziswa kabanzi ekwenziweni kwemishini yezemidlalo, njenge-basketball, ibhola lezinyawo, i-volleyball kanye nezinye izinto zokubopha ibhola, kanye nama-ski, ama-skateboard, ama-cushion esihlalo sebhayisikili, njll., inganikeza ukuguquguquka okuhle kanye nenduduzo, ithuthukise ukusebenza kwezemidlalo.
