Ubulukhuni beI-TPU (i-thermoplastic polyurethane elastomer)yenye yeempawu zayo ezibalulekileyo zomzimba, nto leyo emisela amandla ezinto zokuxhathisa ukuguquka, imikrwelo, kunye nemikrwelo. Ukuqina kudla ngokulinganiswa kusetyenziswa isixhobo sokuvavanya ubunzima beShore, esahlulwe saba ziintlobo ezimbini ezahlukeneyo: iShore A kunye neShore D, esetyenziselwa ukulinganisaIzixhobo zeTPUngeentlobo ezahlukeneyo zobunzima.
Ngokweziphumo zophando, uluhlu lobunzima be-TPU lunokwahluka ukusuka kwi-Shore 60A ukuya kwi-Shore 80D, nto leyo evumela i-TPU ukuba idlule kuluhlu lobunzima berabha kunye neplastiki kwaye igcine ukuthamba okuphezulu kulo lonke uluhlu lobunzima. Ukulungiswa kobunzima kunokufezekiswa ngokutshintsha umlinganiselo wecandelo elithambileyo neliqinileyo kwi-TPU molecular chain. Utshintsho kubunzima lunokuchaphazela ezinye iipropati ze-TPU, ezinje ngokunyusa ubunzima be-TPU okukhokelela ekwandeni kwe-tensile modulus kunye namandla okukrazula, ukwanda kokuqina kunye noxinzelelo lokucinezela, ukwehla kobude, ukwanda koxinano kunye nokuveliswa kobushushu obunamandla, kunye nokwanda kokumelana nokusingqongileyo.
Kwizicelo ezisebenzayo,ukhetho lobunzima be-TPUiya kugqitywa ngokusekelwe kwiimfuno ezithile zesicelo. Umzekelo, i-TPU ethambileyo (elinganiswa yi-Shore A hardness tester) ifanelekile kwiimveliso ezifuna ukuchukumisa okuthambileyo kunye nobude obuphezulu, ngelixa i-TPU eqinileyo (elinganiswa yi-Shore D hardness tester) ifanelekile kwiimveliso ezifuna amandla aphezulu okuthwala umthwalo kunye nokumelana nokuguguleka okuhle.
Ukongeza, abavelisi abahlukeneyo banokuba nemigangatho ethile yokuqina kunye neenkcukacha zemveliso, ezihlala zichazwe kwiincwadi zobugcisa zemveliso. Ukuze ufumane iinkcukacha, nceda ujonge iwebhusayithi esemthethweni yeYantai Linghua New Materials Co., Ltd.
Xa ukhetha izinto zeTPU, ukongeza kubulukhuni, ezinye iimpawu zomzimba, iindlela zokucubungula, ukulungelelaniswa kwendalo, kunye nezinto ezixabisayo kufuneka ziqwalaselwe ukuqinisekisa ukuba izinto ezikhethiweyo zinokuhlangabezana neemfuno zokusebenza kwezicelo ezithile.
