Umehluko phakathi kwabalingisi be-TPR, TPU kanye ne-PU

Njengomthengi oqeqeshiwe wezinto zokusetshenziswa zabakhangisi, kufanele siqale sibe nolwazi olwanele lwezinto ezingavuthiwe ngaphambi kokuba sehlukanise phakathi kokuhle nokubi.Namuhla, ngizokhuluma ngabalingisi abathathu abajwayelekile.Yiziphi izici zayo?

Izici ze-TPU caster: I-TPU iphakeme kakhulu ukumelana nokugqoka, ukumelana nowoyela, ukunwebeka okuhle kakhulu, umthamo omuhle womthwalo, umsindo omkhulu lapho isebenza, impilo ende yesevisi, iyasebenza kumasondo emithwalo kanye nama-caster ahlukahlukene ezimboni, kodwa i-TPU ayimelani ne-hydrolysis.

I-TPE caster iyinto enokunwebeka okuphezulu, amandla aphezulu, ukuqina okuphezulu kanye nezici zokubumba umjovo.Inokuvikelwa kwemvelo, ukuphepha okungenabuthi, ububanzi bokuqina okubanzi, indawo enemibala emihle kakhulu, ukuthinta okuthambile, ukumelana nesimo sezulu, ukumelana nokukhathala nokumelana nezinga lokushisa.Inokusebenza okuhle kakhulu kokucubungula, asikho isidingo se-vulcanization, futhi ingaphinda isetshenziswe ukuze kuncishiswe izindleko.Ingasetshenziselwa Ukubumba Umjovo Wesibili.Ingafakwa ngezinto eziyisisekelo ezifana ne-PP, i-PE, i-PC, i-PS noma i-ABS, noma ingabunjwa ngokuhlukana.Izici ze-TPE caster: ukumelana okuhle kakhulu kokugqokwa, ukunwebeka, ukumuncwa ukushaqeka nokusebenza komsindo ophansi, ukunamathela okuhle kakhulu ngepulasitiki eqinile, enobungani bemvelo futhi engenabuthi;ethwala kahle kakhulu, ingabunjwa nge-PA, ipulasitiki eqinile ye-PP.

Izici ze-caster ze-TPR: Ngomqondo othile, i-TPR iyi-TPE, kodwa i-TPR ngakho-ke i-substrate esekelwe ku-SBS, engcono kune-TPE, kodwa ukumelana kwayo nokugqoka akukhona kangcono kune-TPE.Izindleko ze-TPR ziphansi kune-TPE, zingabuye zibunjwe nge-PA, ipulasitiki eqinile ye-PP.Isetshenziselwa i-heavy duty casters, kanye nabalingisi bezokwelapha.

I-TPU, i-TPE, i-TPR izinhlobo ezintathu zama-caster njengamanje ziyizinto ezisetshenziswa kakhulu zokusetshenziswa kwe-caster, futhi kulezi zinhlobo ezintathu zezinto zokusetshenziswa, kunezinhlobo eziningi nabakhiqizi emakethe, okuphinde kwabangela ukuphazamiseka okukhulu kumsebenzisi.Lapho sikhetha lezi, ngaphezu kokuqonda izici zayo siqu, kufanele sahlulele ngokwezidingo zethu;ngoba ikhethiwe ukuxazulula isidingo!
