Egagasini lokusungula izinto ezintsha okusakazeka embonini yokukhiqiza izicathulo emhlabeni wonke, izinto ezihlanganisa ukuqina kwerabha kanye nokucutshungulwa okuhle kakhulu kwepulasitiki zihola ngokuthula ushintsho olukhulu—i-ethylene-vinyl acetate copolymer, eyaziwa ngokuthi i-EVA. Njengesisekelo sobuchwepheshe bezinto zezicathulo zesimanje, i-EVA, enesakhiwo sayo se-foam esiyingqayizivele esinezimbobo, izakhiwo ezimangalisayo zokusika okulula, kanye nokuzivumelanisa nezimo okuqinile komklamo, ishintsha imingcele yokusebenza kanye nolwazi lokugqoka izicathulo—kusukela ezingutsheni zemidlalo zobungcweti kuya ezicathulweni zemfashini zansuku zonke.

Izici Eziyinhloko: Ukuthuthukiswa Kobunjiniyela Ekuklanyweni Kwezicathulo

Izinzuzo eziyinhloko ze-EVA embonini yezicathulo zivela ekwakhiweni kwayo okulungisekayo kanye nezakhiwo zayo zomzimba. Ngokulawula inqubo yokugqwala, ubuningi bezinto bungalungiswa ngokuguquguqukayo ngaphakathi kobubanzi obungu-0.03–0.25g/cm³, kuhlinzekwe ngezixazululo eziqondiwe zezinhlobo ezahlukene zezicathulo:

1.Ukusekela Okuphelele:Ama-midsole e-EVA anwebeka kakhulu angafinyelela izinga lokubuyisa amandla elingu-55%–65%, amunce ngempumelelo amandla okushaya ngesikhathi sokunyakaza futhi anciphise umthwalo wamalunga cishe ngo-30%.

2.Okuhlangenwe nakho Okulula:Kufika ku-40%–50% elula kunezithende zerabha zendabuko, okuthuthukisa kakhulu induduzo ngesikhathi sokuguguleka isikhathi eside kanye nokuqina kwezemidlalo.

3.Ukuqina Nokuzinza:Isakhiwo samaseli avaliwe sinikeza ukumelana okuhle kakhulu nokuguqulwa kokucindezelwa (<10%), okuqinisekisa ukuthi i-sole igcina isimo sayo sokuqala ngisho nangemva kokusetshenziswa isikhathi eside.

4.Ukuzivumelanisa Nezimo Kwezemvelo: Izakhi ezimelana nesimo sezulu zigcina ukusebenza okuzinzile emazingeni okushisa aphezulu kakhulu kusukela ku--40°C kuya ku-70°C, zivumelana nezimo zezulu ezahlukahlukene emhlabeni jikelele.

Ukusungula Izinto Ezintsha Kwezobuchwepheshe: Kusukela Ekuphefumuleni Okuyisisekelo Kuya Ekuphenduleni Okuhlakaniphile

Amalebhu ahamba phambili emhlabeni wonke aqhuba ubuchwepheshe be-EVA esizukulwaneni sawo sesithathu:

1.Ubuchwepheshe Bokuqina Kwe-Gradient:Ifinyelela izindawo eziningi zobuningi enyaweni eyodwa yezicathulo (isb., ukugoba okuphezulu enyaweni yangaphambili, ukugoba okukhulu esithendeni) ukuze ivumelane nezidingo ze-biomechanical ngokuguquguqukayo.

2.Ukuqhuma Kwe-Fluid Okubaluleke Kakhulu:Isebenzisa i-CO₂ noma i-N₂ ukufaka esikhundleni sama-chemical blowing agents, ilawula ububanzi be-pore bube ngama-micrometer angu-50–200 futhi ithuthukisa ukufana ngo-40%.

3.Izinhlelo Ezihlanganisiwe Ezisebenzayo:Hlanganisa izinhlayiya ezilwa namagciwane (ama-ion esiliva/ama-oxide e-zinc), ama-microcapsules okushintsha kwesigaba (ibanga lokulawula izinga lokushisa elingu-18–28°C), kanye namadayi aphendulayo ahlakaniphile.

4.Ukusungula Izinto Ezisimeme:I-EVA esekelwe ku-bio (etholakala ku-ethanol yomoba) yehlisa ukunyathela kwekhabhoni ngo-45%, kanti izinhlelo zokuvuselela kabusha ezivaliwe zifinyelela amazinga okusebenzisa kabusha izinto adlula u-70%.

Izimo Zokusebenza: Uguquko Lokusebenza Kuzo Zonke Izigaba Zezicathulo

Izicathulo Zobungcweti Zokugijima:

Izicathulo Zomjaho: Izinyawo eziphakathi ze-EVA ezine-foam ezibucayi kakhulu ezinobukhulu obungu-0.12–0.15 g/cm³ zifinyelela amazinga okubuyisa amandla >80%.

Izicathulo Zebhola Lomnqakiswano: Izakhiwo ze-midsole ezihlanganisiwe ezinezingqimba eziningi zithuthukisa ukuncishiswa komthelela ngo-35%, kanye ne-modulus yokusekela eceleni efinyelela ku-25 MPa.

Izicathulo Zomzila: Izakhi zokwakheka ze-VA eziphezulu (28%–33%) zigcina ukuguquguquka ku--20°C, zithuthukisa ukubamba ezindaweni ezishelelayo.

Izicathulo Zokuphila Nezemfashini:

Izicathulo Ezivamile: Ubuchwepheshe be-micro-foaming bunikeza ulwazi lokuthinta "olufana nefu", olwenza ngcono ukusatshalaliswa kwengcindezi ngo-22% ngesikhathi sokugqoka okuqhubekayo kwamahora angu-24.

Izicathulo Zebhizinisi: Izinhlelo zokucasha ezingabonakali ezinezendlalelo ze-EVA ezi-3mm ezincane kakhulu zinikeza ukwesekwa kwe-arch usuku lonke.

Izicathulo Zezingane: Izinsika zangaphakathi ezigxile ekukhuleni okunamandla ezinezakhiwo ezihlakaniphile ezisabela ekushiseni ezivumelana nezinyawo zezingane ezisakhula.

Ukuthuthukiswa Kokukhiqiza: Ipharadayimu Entsha Yokukhiqiza Kwedijithali

Izimboni ezihlakaniphile zishintsha indlela yokukhiqiza izicathulo ze-EVA:

Ukubumba Kokucindezela Okune-4D:Yenza ngokwezifiso ubuningi be-zonal ngokusekelwe kudatha enkulu yokuhamba, kunciphisa imijikelezo yokukhiqiza ibe yimizuzwana engama-90 ngepheya ngalinye.

Ubuchwepheshe Bokubhoboza I-Laser Micro:Ilawula ngokunembile ukuphefumula kwesakhiwo se-foam, ifinyelela ubuningi be-micro-pore obungu-5,000–8,000 nge-cm² ngayinye.

Ukulandelela kwe-Blockchain:Ilandelela umkhondo wekhabhoni kulo lonke umjikelezo wokuphila, kusukela ezintweni zokusetshenziswa ezisekelwe ku-bio kuya emikhiqizweni yokugcina engasetshenziswa kabusha.

Ikusasa Elisimeme: Umsunguli Oyinhloko Wezicathulo Eziluhlaza

Imikhiqizo ehamba phambili embonini isivele isungule amamodeli omnotho ojikelezayo we-EVA:

Iphrojekthi ye-Adidas ye-Futurecraft.Loop ifinyelela izicathulo zokugijima ze-EVA ezingaphinde zisetshenziswe eziyi-100%.

Uhlelo lwe-Nike's Grind luguqula i-EVA ephinde yasetshenziswa ibe yizinto zemidlalo, lucubungula amapheya angaphezu kwezigidi ezingu-30 ngonyaka.

Ubuchwepheshe obusha bokususa i-polymerization yamakhemikhali bufinyelela izinga lokubuyisa i-monomer ye-EVA elingu-85%, okuphindwe kathathu inani uma kuqhathaniswa nokusetshenziswa kabusha okungokoqobo kwendabuko.
