Izinkinga zemvelo ziya ngokuya zigqama njengoba intuthuko yezomnotho iqhubeka, futhi ukufeza i-chemistry eluhlaza kuwumsebenzi ophuthumayo kulezi zinsuku.
Ubuchwepheshe be-foam obugxile kakhulu buwubuchwepheshe obusha obushintshayo, izinto ezisebenzisa amagwebu ezisetshenziswa kubuchwepheshe be-foam obugxile kakhulu ngokuvamile ziyi-carbon dioxide egxile kakhulu (ScCO2).2) kanye ne-supercritical nitrogen (ScN)2), zombili ezisetshenziswa ngaphandle komthwalo wemvelo.
Ekusetshenzisweni kwezicathulo, i-Supercritical Foam Technology iguqula imboni yezicathulo. Lobu buchwepheshe buvumele abakhiqizi bezicathulo ukuthi bandise uhla lwabo lwezinto zokwakha ngale kwe-TPU, i-TPE, ne-EVA yendabuko. Manje, bangasebenzisa nezinto ezifana ne-PEBAX, i-ETPU, nezinye i-elastomers ukudala izicathulo ezine-cushion kanye nokusekelwa okuphezulu, kuyilapho zilula, zihlala isikhathi eside, zikhululekile, futhi zinobungani nemvelo.
Kodwa ngokusebenzisa ubuchwepheshe bokwenza igwebu elibucayi kakhulu ukukhiqiza igwebu le-EVA kushintshe indlela izimboni eziningi ezisebenzisa ngayo lokhu. Lobu buchwepheshe busebenzisa inhlanganisela yokucindezela okuphezulu kanye nokushisa ukudala igwebu elilula, elihlala isikhathi eside, futhi elimelana kakhulu nokuguga. Le nqubo ihilela ukufaka igesi, njenge-carbon dioxide (ScCO2).2), ibe yisisombululo esiwuketshezi se-resin ye-EVA nezinye izithasiselo. Igesi bese ishiswa futhi icindezelwe ize ifike esimweni esibucayi kakhulu, okubangela ukuthi igesi ikhule ngokushesha futhi yakhe amabhamuza amancane. Lawa mabhamuza abe esebanjwa esixazululweni esiwuketshezi, okwenza i-foam enezakhiwo ezinhle kakhulu uma kuqhathaniswa nama-foam endabuko. Iyashesha, ilula, inamandla, futhi ihlala isikhathi eside, okwenza kube ukukhetha okuhle kwezinhlelo ezahlukene zokusebenza. Isibonelo, kusukela ezicathulweni inikeza ukugoqa nokusekela izinyawo kuya emikhiqizweni yenhlanzeko, imikhiqizo yokuzilibazisa kwezemidlalo, omata baphansi/be-yoga, amathoyizi, ukupakishwa, amadivayisi ezokwelapha, imishini yokuzivikela, imikhiqizo engasheleli emanzini, amaphaneli e-photovoltaic, nokuningi... Iphinde isetshenziswe ezinhlelweni zezimoto nezindiza ukuhlinzeka ngokushisa nokuvikela umsindo.
Ubuchwepheshe Bezinto Ezisimeme Zokusungula Izinto Ezintsha ezenziwe nge-foam ye-EVA!
Kodwa-ke, ukusetshenziswa kobuchwepheshe bokwenza igwebu elibukhali kakhulu ukukhiqiza izinto ze-EVA kudinga ukunakwa endabeni yokuhlanganisa amagwebu. Amaketanga e-molecular e-EVA aqondile futhi adinga isakhiwo esihlanganisiwe ukuze avale igesi. Nakuba isivele ikhiqizwa ezicathulweni nakwezinye izindawo, ayisetshenziswanga ngezinga elikhulu. Inkinga enkulu yokwenza igwebu elibukhali kakhulu ukuthi izinga lomkhiqizo oqediwe liphansi kakhulu, lingaphansi kuka-50%, ngaleyo ndlela kuvinjelwe ukuthuthukiswa kokwenza igwebu elibukhali kakhulu.
I-EVA ihlanganiswe nobuchwepheshe be-Si-TPV bokufoma kabusha be-EVA obungasetshenziswa kabusha obungu-100%, Lobu buchwepheshe be-foam be-EVA buyasiza ekushayeleni ama-sneakers ngendlela ekhululekile nehlala isikhathi eside. Okungagcini nje ngokufinyelela ubuningi obuphansi kanye nokuqina okuphezulu kodwa futhi kunokumelana okuhle kakhulu nokuguguleka, izinga lokuncipha kokushisa, umbala ofanayo, izinga lomkhiqizo oqediwe eliphezulu, ukusebenza okulula, kanye nezindleko eziphansi, Qhathanisa ne-supercritical foam.
Njengoba izimboni eziningi ziqala ukusebenzisa le Soft EVA Foam Modifier Si-TPV ehlanganiswe nobuchwepheshe be-EVA, singalindela ukubona ukusetshenziswa okusha kakhulu kwale nto entsha eshintshashintshayo. Ukusha akugcini nje embonini yezicathulo ezithambile nezithambile ezithambile.
Uma ufuna izixazululo zezinto ze-Flexible Soft EVA Foam, i-Modifier inciphisa ukucindezelwa kwe-EVA foam, ubuchwepheshe be-Chemical foam ye-EVA foam elula, i-Soft EVA Foam Modifier noma izixazululo ze-supercritical foam.
Sicela uxhumane nathi, ukuze ufunde kabanzi.
