Sisetshenziswa kanjani isikhwama se-EVA embonini yezicathulo?

Embonini yezicathulo, impahla ye-EVA (ethylene-vinyl acetate copolymer) isetshenziswa kakhulu ekwenzeni imikhiqizo ehlukahlukene yezicathulo ngenxa yokusebenza kwayo okuhle kakhulu. Okulandelayo izindlela ezithile zohlelo lokusebenza kanye nezinzuzo zeEVAizinto embonini yezicathulo:

1. Izinto zodwa:
I-EVA iyinto evamile yamatheni ngenxa yokuqina kwayo, ukuguquguquka nekhono lokumunca ukushaqeka. Inikeza induduzo kumuntu ogqokile futhi ingakwazi ukumelana nokucindezela kokuguga kwansuku zonke. Isici esiyinhloko se-EVA soles isisindo esincane kanye nokunwebeka okuphezulu, okuvumela ogqokile ukuthi azizwe elula lapho ehamba. Ngesikhathi esifanayo, ukusebenza kwayo okuhle kwe-cushioning kunganciphisa ngokuphumelelayo umthelela wonyawo emhlabathini futhi kunciphise ukulimala kwezemidlalo.

2. Inqubo yokukhipha amagwebu:
Ukusetshenziswa kwezinto ze-EVA ezicathulweni ngokuvamile kuhilela inqubo yokwenza amagwebu ukuze kuthuthukiswe ukuthamba kwayo, ukunwebeka nokusebenza kokumuncwa kokushaqeka. Kunezinqubo ezintathu eziyinhloko zokukhihliza amagwebu kwe-EVA: amagwebu amakhulu endabuko ayisicaba, amagwebu amancane angaphakathi kwesikhunta kanye negwebu elixhumanisa umjovo. Lezi zinqubo zivumela izinto ze-EVA ukuthi zikhiqize amasoli obunzima obuhlukene nokuqina ngokwezidingo zezicathulo ezahlukene ukuze kuhlangatshezwane nezidingo zabathengi abahlukene.

3. Ubuchwepheshe bezicathulo ze-midsole:
Mayelana nobuchwepheshe be-midsole yezicathulo, izinhlanganisela ze-EVA kanye ne-nylon elastomer zamukela ucwaningo oluzimele nokuthuthukiswa kwenqubo yokukhipha amagwebu emisha, engafinyelela ukuminyana okuphansi kakhulu futhi inikeze ukusebenza okuhle kakhulu kwe-rebound. Ukusetshenziswa kwalokhu okuhlanganisiwe kwenza i-midsole yezicathulo ibe lula ngenkathi igcina i-rebound ephezulu, efaneleka kakhulu izicathulo zezemidlalo nezicathulo ezigijimayo.

4. Ukusetshenziswa kwezinto ezivikela imvelo:
Ngokuthuthukiswa kokuqwashisa ngemvelo, imboni yodwa ye-EVA izonaka kakhulu ukukhiqizwa okuhambisana nemvelo futhi ikhuthaze imiqondo yokuvikela imvelo. Ngokuzayo, izinto zokwakha ze-EVA ezinobungani bemvelo zizosetshenziswa kabanzi ukuhlangabezana nesidingo sabathengi semikhiqizo esimeme

5. Ukuthuthukiswa okuhlakaniphile:
Ukukhiqiza okuhlakaniphile kanye nokuphathwa kolwazi kuzosetshenziswa kancane kancane ekukhiqizeni okukodwa kwe-EVA ukuze kuthuthukiswe ukusebenza kahle kokukhiqiza kanye nekhwalithi yomkhiqizo. Isibonelo, ngokushumeka izinzwa ematheni ukuze kuqashwe ukuhamba komuntu ogqokile kanye nedatha yokunyakaza, izidingo zemishini yezemidlalo ehlakaniphile zingahlangatshezwana nazo.

6. Ukuthuthukiswa kwezimakethe ezisafufusa:
Ukuthuthukiswa okujulile kokuhwebelana kwembulunga yonke kuye kwakhulula kancane kancane isidingo sezimakethe ezisafufusa, ikakhulukazi e-Asia nase-Afrika, lapho isidingo sezinto zezicathulo siqhubeka sikhuphuka, esihlinzeka ngamathuba amasha ebhizinisi embonini ye-EVA kuphela.

7. Iqhutshwa imboni ye-photovoltaic:
Ukuthuthukiswa kwemboni ye-photovoltaic kuye kwaletha amaphuzu amasha okukhula embonini ye-EVA, ikakhulukazi ekusetshenzisweni kwamafilimu e-solar photovoltaic encapsulation nezinye izinkambu.

8. I-elastomer yesicathulo esekwe ku-Bio-based EVA:
Ukwenziwa kwezimboni kwe-biomass-based EVA shoe elastomer kwenze intuthuko. Lezi zinto azigcini nje ngokuba nezingxenye zemvelo ze-biomass kanye nephunga eliyingqayizivele, kodwa futhi zinezindawo ezinhle zokulwa namagciwane, i-hygroscopicity kanye ne-dehumidification, engathuthukisa ukusebenza kwenhlanzeko emgodini wezicathulo. Ngasikhathi sinye, inezakhiwo ezinhle kakhulu zomzimba, ezine-deformation yokucindezela okuphansi, i-rebound ephezulu, ukuminyana okuphansi nezinye izici.

Kafushane, ukusetshenziswa kwezinto ze-EVA embonini yezicathulo kunezici eziningi, kusukela ematheni kuye kuma-insoles, kusukela ezicathulweni zendabuko kuya ezicathulweni zezemidlalo zobuchwepheshe obuphezulu, izinto ze-EVA seziphenduke into ebaluleke kakhulu ekukhiqizeni izicathulo ngokukhanya kwazo, induduzo, ukumelana nokugqoka kanye nemvelo. isivikelo. Ngokuthuthuka okuqhubekayo kobuchwepheshe kanye nokukhula kwesidingo semakethe, ukusetshenziswa kwezinto ze-EVA kuzoba banzi futhi kujule.
