Nkhani - Konzani Zovuta za EVA Foam

M'zaka zaposachedwa, msika wa nsapato wapadziko lonse lapansi wawona kuchulukira, kukulitsa mpikisano pakati pa mitundu yapakati mpaka yapamwamba.Kuchulukana kosalekeza kwa malingaliro ndi matekinoloje atsopano mu nsapato kwachititsa kuti pakhale kufunikira kwa zinthu zotulutsa thovu pamakampani opanga nsapato.Zida za thovu za polima zogwira ntchito kwambiri zakhala mwala wapangodya wamayankho ambiri amtundu wamtundu, makamaka pagulu la nsapato zamasewera.

Nsapato zamasewera zili ndi magawo atatu: chapamwamba, midsole, ndi outsole.

Midsole ndiyofunikira kwambiri popereka ma cushion, rebound, komanso kuyamwa mwamphamvu pamasewera.Zimatsimikizira chitetezo komanso kumva bwino, ndikupangitsa kukhala moyo wa nsapato zamasewera.Ukadaulo wazinthu ndi thovu la midsole umasiyanitsa ukadaulo woyambira wamitundu yayikulu yosiyanasiyana.

EVA—Chinthu Choyambirira Chogwiritsidwa Ntchito Kwambiri pa Nsapato:

Ethylene-vinyl acetate copolymer (EVA) ndi thovu loyambirira lomwe limagwiritsidwa ntchito mu midsoles.Chithovu choyera cha EVA nthawi zambiri chimadzitamandira ndi 40-45%, zida zopitilira ngati PVC ndi mphira wokhazikika, wophatikizidwa ndi mawonekedwe monga opepuka komanso osavuta kukonza.

M'munda wa nsapato, njira za EVA zotulutsa thovu nthawi zambiri zimaphatikiza mitundu itatu: yachikhalidwe yathyathyathya yayikulu, thovu laling'ono lopangidwa ndi nkhungu, ndi thovu lolumikizana ndi jakisoni.

Pakadali pano, jekeseni wolumikizira thovu wakhala njira yayikulu pakukonza zinthu za nsapato.

Zovuta za EVA Foam:

Vuto lodziwika bwino ndi thovu zachikhalidwe za EVA ndi kusinthasintha kwawo pang'ono, komwe kumakhudza kuthekera kwawo kopereka chithandizo choyenera, makamaka pazogwiritsa ntchito monga nsapato zamasewera.Vuto lina lodziwika bwino ndi kupezeka kwa compression set ndi kuchepa kwa kutentha pakapita nthawi, zomwe zimakhudza kulimba.Kuphatikiza apo, m'mapulogalamu omwe kukana kuterera ndi kukana kwa abrasion ndikofunikira, thovu lachikhalidwe la EVA litha kulephera kukwaniritsa zofunikira.

Kuti apititse patsogolo mawonekedwe azinthu zopangidwa ndi thovu la EVA, opanga nthawi zambiri amabweretsa zotanuka monga EPDM, POE, OBCs, ndi TPE monga SEBS mu EVA zopangira.Kuphatikizika kwa EPDM kwa katundu wa rabara, POE ya elasticity yayikulu, OBCs for soft crystallinity, TPE for flexibility, etc., ikufuna kukwaniritsa zolinga zosintha.Mwachitsanzo, powonjezera ma elastomer a POE, kulimbanso kwazinthu kumatha kuwonjezeka mpaka 50-55% kapena kupitilira apo.

Innovation EVA Foam: Si-TPV Modifier for Higher Quality and Enhanced Performance

SILIKE Si-TPV ikupereka njira ina mu EVA, osati kungoyang'ana zovuta za magwiridwe antchito komanso imagwirizana ndi zoyeserera zachilengedwe.Kapangidwe kake katsopano komanso kapangidwe kake kamathandizira kuwonetsetsa kuti zogulitsa zimasunga kukhulupirika ndi magwiridwe antchito kwa nthawi yayitali, kuzipangitsa kukhala zodalirika komanso zolimba.kuonetsetsa kuti mitengo yomalizidwa yokwera kwambiri.

Si-TPV (vulcanizate thermoplastic silicone-based elastomer) ndi 100% yobwezeretsanso elastomer, Poyerekeza ndi OBC ndi POE, imachepetsa kwambiri kupsinjika ndi kutentha kwa kutentha kwa zinthu za thovu la EVA.Zowoneka bwino kwambiri zidapangitsa kuti kufewetsa, kufewetsa, kukana kuterera, komanso kukana abrasion, kuchepetsa kuvala kwa DIN kuchokera pa 580 mm.³ku 179mm³.

Kuphatikiza apo, Si-TPV imakulitsa kuchulukitsitsa kwamitundu yazinthu za thovu za EVA.Kupambana kumeneku kumalola opanga kupanga zinthu zowoneka bwino popanda kusokoneza magwiridwe antchito.

Si-TPV iyi ngati njira yosinthira thovu la EVA imapindulitsa kupanga zinthu zotonthoza komanso zokhazikika zokhudzana ndi thovu la EVA monga ma midsoles, zinthu zaukhondo, zosangalatsa zamasewera, pansi, ma yoga, ndi zina zambiri.

Dziwani Za Tsogolo la EVA Foam ndi SILIKE Si-TPV!Kwezani malonda anu kuti akhale okwera kwambiri komanso abwino.Tsegulani kuthekera kwakusintha kwathu kwa Si-TPV komwe kumapita patsogolo kuti mupeze mwayi wosayerekezeka pamapulogalamu anu a thovu a EVA.

Lumikizanani nafe lero kuti muyambe ulendo waukadaulo ndikutanthauziranso zomwe zingatheke ndi thovu la EVA!
