Basa reShangu Midsole

Yakajairika shangu yemitambo yakakamurwa kuita zvikamu zvitatu: yepamusoro, midsole, uye outsole. Iyo midsole inopa cushioning uye rebound, inobata maitiro anogadzirwa panguva yekurovedza muviri, inopa dziviriro, uye yakapfava uye yakagadzikana tsoka inonzwa. Zvinogona kutaurwa kuti midsole mweya wemitambo inomhanya shangu, uye tekinoroji uye furo tekinoroji yemidsole ndiyo zviratidzo zvinosiyanisa yakakosha tekinoroji yemhando huru.

Ndeupi mutsauko pakati EVA uye ETPU, izvo zvinhu zviviri zvinoshandiswa kune shangu midsoles?

EVA: The Backbone of Shoe Materials

Ikemikari zita re EVA is Ethylene Vinyl Acetate Copolymer, iyo inogadzirwa ne ethylene uye vinyl acetate. Kazhinji, zviri mukati mevinyl acetate (VA) zviri pakati pe5% ne40%. Kuenzaniswa ne polyethylene (PE), EVA inounza vinyl acetate monomer mucheni yemolecular, iyo inoderedza iyo yakakwira crystallinity uye inovandudza kuoma, kukanganisa kwekudzivirira, kuenderana kwekuzadza, uye kupisa kuvharisa kuita. Naizvozvo, inoshandiswa zvakanyanya muzvigadzirwa zveshangu dzakafukidzwa, mafirimu anoshanda egreenhouse, kurongedza molds, hot melt adhesives, waya netambo, uye matoyi. Kunyanya muindasitiri yeshangu, EVA inoshandiswa kune zvigaro uye zvinhu zvemukati zvepakati-kusvika-pamusoro-shangu dzekufamba-famba, shangu dzekufamba, slippers, uye shangu.

EVA Performance uye Mutengo

Panyaya yehunyanzvi, EVA inowanzopushwa nemakemikari muforoma muindasitiri yeshangu. EVA magranules anoiswa muforoma uye obva aiswa pasi pekupisa kwepamusoro uye kudzvanyirirwa kwefuro. Furo EVA inogona kuita iyo yega kureruka, uye iyo EVA resin ine kumwe elasticity inopa iyo yega basa rakakodzera rekusimudza, kugadzira EVA foamed shangu zvinhu zvakakodzerwa neshangu dzakajairika uye shangu dzekumhanya. Iyo rebound elasticity ye furo EVA inogona kazhinji kuwedzera kusvika 50-55%, kana kunyange yakakwirira.

EVA zvigadzirwa zvakasanganiswa zvine furo zvinoshandiswa zvakanyanya seyega uye zvemukati zvinhu zvepakati-kusvika-yepamusoro-yekupedzisira-shangu dzeshangu, shangu dzekufamba, slippers, uye shangu. Nekuda kwemutengo mukana we EVA foamed zvinhu, icharamba iri huru yezvinhu sarudzo yemitambo yakawanda shangu kwenguva yakareba mune ramangwana.

ETPU: Revolutionary Foamed Shoe Material

Mabhenefiti Akakosha e TPU

TPU, pfupi ye thermoplastic polyurethane elastomer, iri segmented copolymer inoumbwa ne diisocyanate, chain extender, uye polyol. Chikamu chakapfava chinoumbwa nepolol chinoratidza kuchinjika uye kuoma, nepo diisocyanate ichiita sechikamu chakaoma, ichipa kuoma kwezvinhu uye kuoma. Mushure mechikamu chakaoma chinopenya senge yemuviri-yekubatanidza poindi, TPU inoratidza yakakwirira elasticity. Naizvozvo, TPU ine mabhenefiti akakosha akadai sesimba rakanyanya kusimba, kurebesa kukuru panguva yekuzorora, uye yakaderera-yenguva refu yekumanikidza zvachose deformation rate.

ETPU More Yakanakisa Performance

Panyaya yekugadzira maitiro, kupupa kwemuviri kunoshandiswa kune midsole ye ETPU, iyo ine hushamwari hwezvakatipoteredza uye inogona kushandiswa zvakare pasina chero hwema kana ichienzaniswa nemakemikari anoita furo EVA. Mushure mekuumbwa, inopa popcorn-senge chimiro chine kusimba kwakanyanya uye deformation kudzoreredza, pamwe nekupfeka kuramba uye anti-kutsvedza kuita kwakakwirira kupfuura yechinyakare. EVA zvinhu. The furo TPU, kana ETPU, ine rebound value inosvika 60%, yakakwira zvakanyanya kupfuura ye EVA. Izvi zvinoreva kuti kana shangu ichirova pasi uye ichidzokera shure, iyo chete inodzokera nesimba guru, inobudirira kuderedza kuneta kwemhasuru uye kuderedza kudengenyeka kwemhasuru, zvichiita kuti iwe umhanye kure nesimba rakazara.

ETPU mutengo

Zvisinei, ETPU inodhura kupfuura EVA, iyo yakadzora vamwe vagadziri, uye kune zvimwe zvinonetsa mukugadzirisa innovation. Asi izvi zvipingamupinyi zvenguva pfupi. Vazhinji vagadziri vakaedza kuunza ETPU zvinhu kune yakafara siyana yezasi maapplication. Semuenzaniso, yakabudirira yekutengesa application ndeye ETPU plastiki track. Mumakore achangopfuura, mamwe mashandisirwo ekutengeserana akaonekwa mumunda wedu wekuona, senge ETPU zvigaro zvebhasikoro, mapedhi ekudzivirira emitambo, ETPU matinji evana anokambaira, ngowani yebhasikoro padding, padding zvigaro zvemotokari, zvichingodaro.

Yose zvayo, ETPU inodhura kupfuura EVA uye zvakaoma kuparadzanisa kubva kuAdidas label effect. Zvisinei, ETPU zviri nani kupfuura EVA maererano ne rebound kugona, deformation kupora, kupfeka kuramba, uye anti-slip performance. Chinonyanya kukosha, ETPU inopindirana nemaitiro egirinhi kuchengetedza kwezvakatipoteredza. Nokudaro, pakusarudza zvinhu zveshangu midsoles yakanaka, zvinhu zvakadai sechitarisiko, kunyorova, uye kunyaradza kweshangu zvinofanirawo kufungwa, uye mutengo wepamusoro weshangu unonzwisisika.
