Ukuze utadishe ukuziphatha kwe-crystallization kanye nezakhiwo ze-PA66 ezilungiswe izinhlobo ezahlukene zenayiloni enayiloni enuka kamnandi, izinhlobo ezahlukene zenhlaka enayiloni enephunga elimnandi zengezwa ku-PA66 resin, kanye nemiphumela yezinhlobo ezahlukene nokuqukethwe kwe-semi-aromatics. I-copolymerized nylon resin ekuziphatheni kwe-crystallization kanye nezakhiwo zezinto ze-alloy zafundwa.Imiphumela ibonisa ukuthi izinhlobo ezihlukene zamareyini enayiloni e-copolymerized anephunga elimnandi anokuziphatha okucwebezelayo okuhlukile nokuqukethwe okulungile ekuhlanganisweni.Ngokukhuphuka kokuqukethwe kwe-poly-m-xylyleneadipamide (MXD6), izinga lokushisa elincibilikayo (Tm) kanye nezinga lokushisa elicwebezelayo (Tc) yokuncipha kwenhlanganisela, ukuqina nokuguquka kokushisa kokwanda kwenhlanganisela, ukuqina kwe-mc nokumuncwa kwamanzi kuncipha, futhi ukuminyana kunomphumela omncane.Lapho inani elingeziwe le-polyphthalamide(PA6T/6) likhulu noma lilingana no-40% wengxenye ye-resin, ukuziphatha kwe-crystallization yenhlanganisela kuqala ukushintsha kakhulu, ukuqina nokuguquka okushisayo kwenhlanganisela kuyathuthukiswa, futhi ukuqina kuyaqina. kuncishisiwe.Ngokukhula kokuqukethwe kwe-PA6T/6, ukumuncwa kwamanzi kwenhlanganisela kuncipha, futhi ukuminyana kunomphumela omncane.Uma inani elingeziwe le-poly(p-phenyl-pentadiamine) (PA5T) likhulu noma lilingana no-30% wengxenye ye-resin, i-PA5T iqala ukudlala indima ekuhlanganiseni, ukuqina kuyancishiswa, ukumuncwa kwamanzi kuyancishiswa.Ukumuncwa kwamanzi kwenhlanganisela kuqala kuncipha bese kukhuphuka ngokwanda kokuqukethwe kwe-PA5T, futhi inani elingeziwe le-PA5T alinawo umthelela omncane ekumineni kwenhlanganisela.Lapho inani le-polydecamethylene terephthalate (PA10T) lingaphansi kuka-40% wengxenye ye-resin, i-Tm kanye no-Tc yenhlanganisela iyancipha kancane kancane, ukuqina kanye ne-thermal deformation mc yenhlanganisela iyathuthukiswa, futhi ukuqina kuyehla.Ukumuncwa kwamanzi kwenhlanganisela kwehla ngokunyuka kokuqukethwe kwe-PA10T.Uma inyuswa ibe yi-50% yengxenye ye-resin, ukumuncwa kwamanzi akusancishiswa, futhi ukuqina nokuguqulwa kokushisa akusathuthukisiwe.
