Kodi chikwama cha EVA chimagwiritsidwa ntchito bwanji pamsika wa nsapato?

M'makampani opanga nsapato, zinthu za EVA (ethylene-vinyl acetate copolymer) zimagwiritsidwa ntchito kwambiri popanga nsapato zosiyanasiyana chifukwa chakuchita bwino. Zotsatirazi ndi zenizeni ntchito njira ndi ubwino waEVAzida zopangira nsapato:

1. Zinthu zokhazokha:
EVA ndi chinthu chodziwika bwino pamiyendo chifukwa cha kulimba kwake, kusinthasintha komanso kugwedezeka kwamphamvu. Zimapereka chitonthozo kwa mwiniwake ndipo zimatha kupirira kupsinjika kwa kuvala kwa tsiku ndi tsiku. Mbali yaikulu ya zitsulo za EVA ndizolemera kwambiri komanso kusungunuka kwakukulu, zomwe zimapangitsa kuti wovalayo azimva kuwala pamene akuyenda. Panthawi imodzimodziyo, ntchito yake yabwino yothandizira imatha kuchepetsa mphamvu ya phazi pansi ndikuchepetsa kuvulala kwamasewera.

2. Kuchita thovu:
Kugwiritsa ntchito zida za EVA mu nsapato nthawi zambiri kumaphatikizapo kuchita thovu kuti ziwongolere kufewa kwake, kukhazikika kwake komanso kuyamwa kwake. Pali njira zitatu zazikulu zochitira thovu za EVA: zachikhalidwe zothimbirira thovu zazikulu, zotulutsa thovu mu nkhungu zazing'ono ndi jekeseni wolumikizira thovu. Njirazi zimathandizira kuti zida za EVA zipange zowola zolimba komanso makulidwe osiyanasiyana malinga ndi zosowa za nsapato zosiyanasiyana kuti zikwaniritse zosowa za ogula osiyanasiyana.

3. Tekinoloje ya nsapato ya midsole:
Pankhani yaukadaulo wa nsapato za midsole, makina a EVA ndi nayiloni elastomer amatengera kafukufuku wodziyimira pawokha komanso njira yopangira thovu, yomwe imatha kukhala yotsika kwambiri ndikupereka magwiridwe antchito abwino kwambiri. Kugwiritsiridwa ntchito kwa zinthu zophatikizikazi kumapangitsa nsapato ya midsole kukhala yopepuka kwinaku ikusunga kubweza kwapamwamba, komwe kuli koyenera makamaka nsapato zamasewera ndi nsapato zothamanga.

4. Kugwiritsa ntchito zinthu zoteteza chilengedwe:
Ndikusintha kwa chidziwitso cha chilengedwe, makampani a EVA okhawo azipereka chidwi kwambiri pakupanga zachilengedwe komanso kulimbikitsa malingaliro oteteza chilengedwe. M'tsogolomu, zida za EVA zokomera chilengedwe zidzagwiritsidwa ntchito kwambiri kukwaniritsa zofuna za ogula pazinthu zokhazikika

5. Kukula mwanzeru:
Kupanga mwanzeru ndi kasamalidwe ka chidziwitso pang'onopang'ono kudzagwiritsidwa ntchito pakupanga kwa EVA kokha kuti apititse patsogolo kupanga bwino komanso mtundu wazinthu. Mwachitsanzo, poika masensa m'miyendo kuti ayang'anire momwe wovalayo akuyendera komanso kayendetsedwe kake, zofunikira za zida zamasewera zanzeru zitha kukwaniritsidwa.

6. Kukula kwa msika womwe ukutuluka:
Kukula mozama kwa kudalirana kwa mayiko kwatulutsa pang'onopang'ono kufunikira kwa misika yomwe ikubwera, makamaka ku Asia ndi Africa, komwe kufunikira kwa nsapato kukukulirakulira, zomwe zimapereka mwayi watsopano wamabizinesi kumakampani okhawo a EVA.

7. Moyendetsedwa ndi mafakitale a photovoltaic:
Kukula kwa mafakitale a photovoltaic kwabweretsanso mfundo zatsopano za kukula kwa makampani a EVA, makamaka pakugwiritsa ntchito mafilimu opangira dzuwa a photovoltaic encapsulation ndi zina.

8. Bio-based EVA nsapato elastomer:
Kukula kwa mafakitale a biomass-based EVA shoe elastomer kwapita patsogolo. Izi sizingokhala ndi zigawo za biomass zachilengedwe komanso kununkhira kwapadera, komanso zimakhala ndi antibacterial properties, hygroscopicity ndi dehumidification, zomwe zingapangitse ntchito zaukhondo mu nsapato za nsapato. Nthawi yomweyo, ili ndi zinthu zabwino kwambiri zakuthupi, zokhala ndi kupsinjika pang'ono, kubweza kwakukulu, kachulukidwe otsika ndi mawonekedwe ena.

Mwachidule, kugwiritsa ntchito zida za EVA m'makampani opanga nsapato kumakhala kosiyanasiyana, kuchokera kumapazi kupita ku insoles, kuchokera ku nsapato zachikhalidwe kupita ku nsapato zamasewera apamwamba kwambiri, zida za EVA zakhala chinthu chofunikira kwambiri popanga nsapato ndi kupepuka kwawo, chitonthozo, kukana kuvala komanso chilengedwe. chitetezo. Ndi kupita patsogolo kosalekeza kwaukadaulo komanso kukula kwa kufunikira kwa msika, kugwiritsa ntchito zida za EVA kudzakhala kokulirapo komanso mozama.
