Mukufambira mberi kwekuvandudzwa kuri kuitika muindasitiri yekugadzira shangu pasi rose, chinhu chinosanganisa kusimba kwerabha nekugona kugadzikiswa kwemapurasitiki zviri kutungamira chinyararire shanduko huru—ethylene-vinyl acetate copolymer, inozivikanwa seEVA. Senzira huru yetekinoroji yemazuva ano yeshangu, EVA, ine chimiro chayo chefuro chine maburi akasiyana, hunhu hwayo hwehutete hwakareruka, uye kugona kwayo kuchinjika, iri kuchinja miganhu yekushanda uye ruzivo rwekupfeka shangu—kubva pazvipfeko zvehunyanzvi zvemitambo kusvika kushangu dzemazuva ese dzefashoni.

Hunhu Hukuru: Kubudirira Kweinjiniya Mukugadzira Shangu

Mabhenefiti makuru eEVA muindasitiri yeshangu anobva muchimiro chayo chinogadziriswa zvakanaka uye hunhu hwayo hwepanyama. Nekudzora maitiro ekufuridza furo, huwandu hwezvinhu hunogona kugadziriswa zviri nyore mukati me 0.03–0.25g/cm³, zvichipa mhinduro dzakanangana nemhando dzakasiyana dzeshangu:

1.Kuchengetedza Kwekupedzisira:Matinji eEVA ane elasticity yepamusoro anogona kuwana simba rekudzoka kubva pa55% kusvika 65%, achinyatso tora simba rekukanda panguva yekufamba uye achideredza mutoro wemajoini neanenge 30%.

2.Ruzivo Rwakareruka:Kusvika 40%–50% yakareruka kupfuura jira rerabha rechinyakare, zvichiwedzera runyararo panguva yekupfeka kwenguva refu uye kumhanya kwemuviri.

3.Kugara kwenguva refu uye Kugadzikana:Maumbirwo emasero akavharwa anopa simba rakanaka rekudzivirira kudzvanywa (<10%), zvichiita kuti chitsiga chirambe chine chimiro chacho chepakutanga kunyangwe mushure mekushandiswa kwenguva refu.

4.Kuchinjika Kwezvakatipoteredza: Mafomura anodzivirira mamiriro ekunze anochengetedza kushanda kwakasimba munzvimbo dzinopisa zvakanyanya kubva pa -40°C kusvika 70°C, achichinjika kune mamiriro ekunze akasiyana-siyana pasi rese.

Kuvandudzwa Kwetekinoroji: Kubva Pakuburitsa Furo Kusvika Pakupindura Nehungwaru

Marabhoritari makuru epasi rose ari kusimudzira tekinoroji yeEVA muchizvarwa chechitatu:

1.Tekinoroji yeGradient Density:Inokwanisa kuita nzvimbo dzakawanda dzehuremu mutsoka imwe chete (semuenzaniso, kudzoreredza kwakakwirira mutsoka, kusungirira zvakanyanya muchitsitsinho) kuti ienderane nezvinodiwa nemuviri.

2.Kuburitsa Furo Rinopenya Zvikuru:Inoshandisa CO₂ kana N₂ kutsiva mishonga inoputira makemikari, ichidzora dhayamita dzemapore kusvika kuma micrometer makumi mashanu kusvika mazana maviri uye ichivandudza kufanana kwayo ne40%.

3.Masisitimu Anoshanda Anosanganisa:Sanganisa zvinhu zvinorwisa mabhakitiriya (silver ions/zinc oxides), phase-change microcapsules (kudzora tembiricha iri pakati pe18–28°C), uye madhayi akachenjera anopindura.

4.Kugadzira Zvinhu Zvitsva Kunogara Kwakagadzikana:EVA inobva mumafuta emunzimbe (inobva mu ethanol yenzimbe) inoderedza kukanganiswa kwecarbon ne45%, nepo masisitimu ekudzokorodza zvinhu akavharwa achikwanisa kushandisazve zvinhu kupfuura 70%.

Maitiro Ekushandisa: Shanduko Yekushanda Muzvikamu Zvese Zveshangu

Shangu dzeMitambo dzeNyanzvi:

Shangu dzemujaho: Matinji epakati eEVA ane furo rakasimba ane huremu hwe0.12–0.15 g/cm³ anowana simba rinodzoka >80%.

Shangu dzeBasketball: Zvimiro zvepakati petsoka zvine layer yakawanda zvinovandudza kuderera kwesimba ne35%, ne lateral support modulus inosvika 25 MPa.

Shangu dzeTrail: Mishonga ine VA yakawanda (28%–33%) inochengetedza kuchinjika pa -20°C, zvichiita kuti ibate panzvimbo dzinotsvedza.

Mararamiro uye Fashoni Shangu:

Shangu Dzemhando Yepamusoro: Tekinoroji ye micro-foaming inopa ruzivo rwekubata "rwakafanana negore", ichivandudza kugoverwa kwekumanikidzwa ne22% panguva yekupfeka kwemaawa makumi maviri nemana nguva dzose.

Shangu dzeBhizinesi: Masisitimu ekushongedza asingaonekwe ane 3mm EVA layers dzakatetepa kwazvo anopa rutsigiro rwekukotama kwezuva rese.

Shangu dzeVana: Maziso emukati anotarisa kukura ane maumbirwo akangwara anoenderana nekupisa uye anochinjika kutsoka dzevana dziri kukura.

Kuvandudzwa Kwekugadzira: Nzira Itsva Yekugadzira Kwedhijitari

Mafekitori akangwara ari kuchinja kugadzirwa kweshangu dzeEVA:

Kuumbwa kwe4D Compression:Inogadzirisa huwandu hwenzvimbo zvichienderana nedata guru rekufamba, zvichiita kuti kugadzirwa kuite masekondi makumi mapfumbamwe papeya imwe neimwe.

Tekinoroji yeLaser Micro-Perforation:Inodzora nemazvo kufema kwechimiro chefuro, zvichiita kuti pave nehuwandu hwemapore madiki e5,000–8,000 pa cm².

Kutevedzana kweBlockchain:Inotevedzera mafambiro ecarbon muhupenyu hwese, kubva pazvinhu zvakagadzirwa nebio kusvika kuzvigadzirwa zvinogona kushandiswazve.

Ramangwana Rinochengetedza: Chinhu Chinonyanya Kukosha paKushanda Kweshangu Dzegirini

Makambani makuru muindasitiri akatotanga mamodheru ehupfumi hweEVA:

Chirongwa cheAdidas cheFuturecraft.Loop chakawana 100% EVA running shoes dzinogona kushandiswazve.

Chirongwa cheNike's Grind chinoshandura EVA inoshandiswazve kuita zvinhu zvemitambo, zvichigadzira mapeya anopfuura mamiriyoni makumi matatu pagore.

Tekinoroji itsva yekubvisa polymerization yemakemikari inoita kuti EVA monomer iwane mukana wekudzoreredza 85%, zvichiwedzera katatu kukosha kwayo zvichienzaniswa nekudzokorodza kwekare.
