Mu funde la zatsopano zomwe zikufalikira padziko lonse lapansi popanga nsapato, chinthu chomwe chimaphatikiza kulimba kwa rabara ndi kuthekera kwabwino kwa pulasitiki kukupangitsa kusintha kwakukulu pang'onopang'ono—ethylene-vinyl acetate copolymer, yotchedwa EVA. Monga mwala wapangodya wa ukadaulo wamakono wa nsapato, EVA, yokhala ndi kapangidwe kake kapadera ka thovu lokhala ndi mabowo, mawonekedwe ake opepuka kwambiri otetezera, komanso kusinthasintha kwamphamvu kwa kapangidwe, ikusintha malire a magwiridwe antchito ndi luso lovala nsapato—kuchokera ku zida zamasewera mpaka nsapato zamafashoni za tsiku ndi tsiku.

Makhalidwe Abwino Kwambiri: Kupambana kwa Uinjiniya pa Kupanga Nsapato

Ubwino waukulu wa EVA mumakampani opanga nsapato umachokera ku kapangidwe kake kakang'ono komanso mawonekedwe ake enieni. Mwa kuwongolera njira yopangira thovu, kuchuluka kwa zinthuzo kumatha kusinthidwa mosavuta mkati mwa 0.03–0.25g/cm³, kupereka mayankho olunjika a mitundu yosiyanasiyana ya nsapato:

1.Chitsulo Chomaliza:Ma midsole a EVA okhala ndi elasticity yapamwamba amatha kupeza mphamvu yobwerera ya 55%–65%, zomwe zimathandiza kuyamwa mphamvu zogwira ntchito panthawi yoyenda ndikuchepetsa katundu wa mafupa ndi pafupifupi 30%.

2.Chidziwitso Chopepuka:Kufikira 40%–50% yopepuka kuposa nsapato za rabara zachikhalidwe, zomwe zimapangitsa kuti chitonthozo chikhale cholimba kwambiri pakagwiritsidwa ntchito nthawi yayitali komanso kuthamanga kwa masewera olimbitsa thupi.

3.Kulimba ndi Kukhazikika:Kapangidwe ka selo lotsekedwa kamapereka kukana bwino kwambiri ku kusintha kwa kupsinjika (<10%), kuonetsetsa kuti chidendenecho chimasunga mawonekedwe ake oyambirira ngakhale chitakhala chogwiritsidwa ntchito kwa nthawi yayitali.

4.Kusintha kwa Zachilengedwe: Ma formula olimbana ndi nyengo amasunga magwiridwe antchito okhazikika pa kutentha kwakukulu kuyambira -40°C mpaka 70°C, akusintha malinga ndi nyengo zosiyanasiyana padziko lonse lapansi.

Zatsopano pa Ukadaulo: Kuyambira pa Kutulutsa Thovu Loyambira mpaka pa Kuyankha Mwanzeru

Ma laboratories otsogola padziko lonse lapansi akuyendetsa ukadaulo wa EVA mu m'badwo wake wachitatu:

1.Ukadaulo wa Kuchuluka kwa Maginito:Imakwaniritsa madera angapo okhuthala mu chidendene chimodzi cha nsapato (monga, kugwedezeka kwambiri kutsogolo kwa phazi, kugwedezeka kwambiri pachidendene) kuti igwirizane ndi zosowa za biomechanical.

2.Kutulutsa Thovu la Madzi Oopsa Kwambiri:Amagwiritsa ntchito CO₂ kapena N₂ m'malo mwa mankhwala ophera, kulamulira ma pore diameters kufika pa 50–200 micrometers ndikuwonjezera kufanana ndi 40%.

3.Machitidwe Ogwira Ntchito Ophatikizana:Phatikizani tinthu tomwe timayambitsa mabakiteriya (silver ions/zinc oxides), ma microcapsules osintha gawo (kulamulira kutentha kwa 18–28°C), ndi utoto woyankha bwino.

4.Zatsopano Zokhazikika:EVA yochokera ku bio-based (yochokera ku ethanol ya nzimbe) imachepetsa kuchuluka kwa mpweya woipa ndi 45%, ndipo njira zobwezeretsanso zinthu zotsekedwa zimapeza kuchuluka kwa kugwiritsanso ntchito zinthu zogwiritsidwanso ntchito kopitilira 70%.

Zochitika Zogwiritsira Ntchito: Kusintha kwa Magwiridwe Antchito Pamagulu Onse a Nsapato

Nsapato Zamasewera Zaukadaulo:

Nsapato Zothamanga: Ma midsole a EVA okhala ndi thovu lolimba kwambiri okhala ndi makulidwe a 0.12–0.15 g/cm³ amakwaniritsa mphamvu yobwerera >80%.

Nsapato za Mpira wa Basketball: Kapangidwe ka midsole ya multi-layer composite kamathandizira kuchepetsa mphamvu ndi 35%, ndi modulus yothandizira mbali imodzi kufika 25 MPa.

Nsapato za Trail: Ma formula okhala ndi VA wambiri (28%–33%) amakhala osinthasintha pa -20°C, zomwe zimathandiza kuti zigwire bwino pamalo oterera.

Nsapato za Moyo ndi Mafashoni:

Nsapato Zosavala Mosavala: Ukadaulo wa micro-foaming umapereka chidziwitso chogwira ngati "mtambo", ndikuwonjezera kugawa kwa kuthamanga ndi 22% panthawi yovala mosalekeza kwa maola 24.

Nsapato Zamalonda: Makina osawoneka bwino okhala ndi zigawo zoonda kwambiri za 3mm EVA amapereka chithandizo cha arch tsiku lonse.

Nsapato za Ana: Ma soli ozungulira kukula kwamphamvu okhala ndi mapangidwe anzeru omwe amasinthasintha kutentha, amagwirizana ndi mapazi a ana omwe akukula.

Kukweza Kupanga: Njira Yatsopano Yopangira Zinthu Za digito

Mafakitale anzeru akukonzanso kupanga nsapato za EVA:

Kuumba kwa 4D Compression:Imasintha kuchuluka kwa zonal kutengera gait big data, kuchepetsa nthawi yopangira mpaka masekondi 90 pa peyala iliyonse.

Ukadaulo Woboola Mapazi a Laser:Amawongolera bwino momwe thovu limapumira, zomwe zimapangitsa kuti pakhale kuchuluka kwa ma pore ang'onoang'ono pakati pa 5,000–8,000 pa cm².

Kutsata kwa Blockchain:Imatsata kuchuluka kwa mpweya womwe umapezeka m'thupi lonse, kuyambira zinthu zopangira zinthu zachilengedwe mpaka zinthu zobwezerezedwanso.

Tsogolo Losatha: Choyambitsa Chidwi cha Nsapato Zobiriwira

Makampani otsogola akhazikitsa kale njira zoyendetsera chuma za EVA:

Pulojekiti ya Adidas ya Futurecraft.Loop yakwaniritsa nsapato zothamanga za EVA zomwe zimabwezerezedwanso 100%.

Pulogalamu ya Nike's Grind imasintha EVA yobwezerezedwanso kukhala zinthu zamasewera, ndipo imakonza ma peya opitilira 30 miliyoni pachaka.

Ukadaulo watsopano wa depolymerization wa mankhwala umapeza chiŵerengero chobwezeretsa EVA monomer cha 85%, kuchulukitsa katatu poyerekeza ndi kubwezeretsanso kwachikhalidwe.
