Kungani Abakhiqizi Bamathoyizi Bezilwane Bekhetha Izinto Ze-TPR?

I-TPR iwuhlobo lwe-polymer ethambile enezakhiwo zokuguquguquka.Ngokwezidingo ezihlukene zamakhasimende, abahlinzeki bahlinzeka ngesistimu yefomula yezinto ezibonakalayo ye-TPE ne-TPR kanye nezisombululo zohlelo lokusebenza.Amandla ekhono le-R & D ayisici esibalulekile sokuhlola amandla aphelele we-TPE nabakhiqizi be-TPR.

Kungani abakhiqizi abaningi bamathoyizi ezilwane ezifuywayo bekhetha izinto ze-TPE esikhundleni sezinto ze-PVC, okokuqala ukuvikela imvelo.I-TPE ne-TPR aziqukethe i-phthalate plasticizer ne-halogen, futhi ukushiswa kwe-TPE ne-TPR akukhiphi i-dioxin nezinye izinto eziyingozi.

Ngokuqina kwamathoyizi ezilwane ezifuywayo, iyunithi yobulukhuni ye-PVC i-p (evezwa okuqukethwe kwe-plasticizer), futhi iyunithi yokuqina ye-TPE ne-TPR iyi-( ikalwa idatha elinganiswa ngomhloli wokuqina wogu a).U-P kanye no-a, izinhlobo ezimbili zobulukhuni, banobudlelwano bokuguqulwa okulinganiselwe.

Ngokuvamile, i-fluidity ye-TPE ne-TPR yimbi kakhulu kunaleyo ye-PVC.Ukushisa kwe-plasticizing kanye nokubumba kwe-TPE ne-TPR kuphakeme kunaleyo ye-PVC (i-TPE, i-TPR ye-plasticizing lokushisa yi-130 ~ 220 ℃, izinga lokushisa le-PVC plasticizing lingu-110 ~ 180 ℃);ngokuvamile, ukuncipha kwe-PVC ethambile kungu-0.8 ~ 1.3%, i-TPE ne-TPR ingu-1.2 ~ 2.0%.

I-TPE ne-TPR zinokumelana okungcono kwezinga lokushisa eliphansi kune-PVC.I-TPE ne-TPR ngeke ziqine kokuthi - 40 ℃ futhi i-PVC izoqina kokuthi - 10 ℃.

I-TPE kanye ne-TPR yamathoyizi ezilwane zingabunjwa ngokubunjwa komjovo, i-extrusion kanye nokubunjwa kokushaywa, kuyilapho i-PVC ingabunjwa ngomjovo, i-extrusion, i-lining kanye nokuwa.
