Ukuqina komgangatho we-TPU-thermoplastic polyurethane elastomers

Ukuqina kweI-TPU (i-thermoplastic polyurethane elastomer)yenye yeempawu zayo ezibalulekileyo zomzimba, ezimisela isakhono semathiriyeli ukuxhathisa i-deformation, imikrwelo, kunye nemikrwelo.Ubunzima buqhele ukulinganiswa kusetyenziswa isixhobo sokuvavanya ubulukhuni beNxweme, esahlulwe saba ziindidi ezimbini ezahlukeneyo: Unxweme A kunye noNxweme D, olusetyenziselwa ukulinganisa.Izinto zeTPUezinobunzima obahlukeneyo.

Ngokweziphumo zophando, uluhlu lobunzima be-TPU lunokusuka kwi-Shore 60A ukuya kwi-Shore 80D, evumela i-TPU ukuba ivule uluhlu lobunzima berabha kunye neplastiki kunye nokugcina ukuqina okuphezulu kulo lonke uluhlu lobunzima.Ukulungelelaniswa kobunzima kunokufezekiswa ngokuguqula umlinganiselo wamacandelo athambileyo kunye anzima kwikhonkco ye-molecular TPU.Ukutshintsha kobulukhuni kunokuchaphazela ezinye iipropathi ze-TPU, ezinjengokonyusa ubulukhuni be-TPU ekhokelela ekwandeni kwemodyuli yokuqina kunye nokukrazula amandla, ukonyuka kokuqina kunye noxinzelelo olucinezelayo, ukuncipha kobude, ukwanda koxinzelelo kunye nokuveliswa kobushushu obuguqukayo. , kunye nokwanda kokuchasana kokusingqongileyo.

Kwizicelo ezisebenzayo, iukhetho lobulukhuni lweTPUiya kumiselwa ngokusekelwe kwiimfuno ezithile zesicelo.Umzekelo, i-TPU ethambileyo (elinganiswe ngu-Shore A tester yobunzima) ifanelekile kwiimveliso ezifuna ukubamba okuthambileyo kunye nobude obuphezulu, ngelixa i-TPU enzima (elinganiswa ngu-Shore D tester hardness) ifanelekile kwiimveliso ezifuna umthamo ophezulu wokuthwala umthwalo kunye nokulungileyo. nxiba ukumelana.

Ukongeza, abavelisi abohlukeneyo banokuba nemigangatho ethile yobulukhuni kunye neenkcukacha zemveliso, ezidla ngokuchazwa kwiincwadi zobugcisa bemveliso.Ngeenkcukacha, nceda ujonge iwebhusayithi esemthethweni yeYantai Linghua New Materials Co., Ltd.

Xa ukhetha izinto ze-TPU, ngaphezu kobunzima, ezinye izinto eziphathekayo, iindlela zokucubungula, ukulungelelaniswa kokusingqongileyo, kunye neemeko zeendleko kufuneka ziqwalaselwe ukuqinisekisa ukuba izinto ezikhethiweyo zinokuhlangabezana neemfuno zokusebenza kwezicelo ezithile.
