Mavuto azachilengedwe akuchulukirachulukira monga chitukuko cha zachuma, ndipo kukwaniritsa chemistry yobiriwira ndi ntchito yofunika kwambiri masiku ano.
Ukadaulo wa supercritical thovu ndiukadaulo watsopano wosinthira, zida zotulutsa thovu zomwe zimagwiritsidwa ntchito muukadaulo wapamwamba kwambiri wa thovu nthawi zambiri zimakhala za carbon dioxide (ScCO).2) ndi supercritical nitrogen (ScN2), onsewa amagwiritsidwa ntchito popanda zolemetsa zachilengedwe.
Pogwiritsira ntchito nsapato, Supercritical Foam Technology ikusintha makampani opanga nsapato.Ukadaulo uwu walola opanga ma sneaker kuti awonjezere zida zawo kupitilira TPU, TPE, ndi EVA.Tsopano, atha kugwiritsanso ntchito zida monga PEBAX, ETPU, ndi ma elastomers ena kuti apange masiketi okhala ndi ma cushioning apamwamba komanso othandizira, pomwe opepuka, olimba, omasuka, komanso okonda zachilengedwe.
Koma ndi ntchito supercritical thobvu luso kubala EVA thovu wasintha njira mafakitale ambiri ntchito nkhaniyi.Ukadaulowu umagwiritsa ntchito kuphatikiza kwamphamvu kwambiri komanso kutentha kuti apange thovu lopepuka, lolimba, komanso losatha kutha kung'ambika.Njirayi imaphatikizapo kubaya mpweya, monga carbon dioxide (ScCO2), mu njira yamadzimadzi ya EVA resin ndi zina zowonjezera.Mpweyawo umatenthedwa ndi kupsinjidwa mpaka ufika pamalo ovuta kwambiri, zomwe zimapangitsa kuti mpweyawo ukule mofulumira ndi kupanga tinthu ting'onoting'ono.Ma thovuwa amatsekeredwa mumtsuko wamadzimadzi, ndikupanga thovu lomwe lili ndi mphamvu zapamwamba poyerekeza ndi thovu lachikhalidwe.Ndi yachangu, yopepuka, yamphamvu, komanso yolimba, zomwe zimapangitsa kukhala chisankho choyenera pamagwiritsidwe osiyanasiyana.Mwachitsanzo, kuchokera ku nsapato kumapereka chithandizo ndi kuthandizira mapazi kuzinthu zaukhondo, zosangalatsa zamasewera, mphasa zapansi / yoga, zoseweretsa, kulongedza, zipangizo zamankhwala, zipangizo zodzitetezera, madzi osasunthika, mapanelo a photovoltaic, ndi zina ... imagwiritsidwanso ntchito m'magalimoto ndi malo opangira ndege kuti apereke zotsekemera komanso zotchingira mawu.
Sustainable Material Technologies for Innovations zopangidwa ndi thovu la EVA!
Komabe, kugwiritsa ntchito ukadaulo wapamwamba kwambiri wopanga thovu kuti apange zida za EVA kumafuna chidwi pa nkhani yolumikizirana.Unyolo wa ma molekyulu a EVA ndi amzere ndipo amafunikira mawonekedwe olumikizirana kuti atseke gasi.Ngakhale kuti zapangidwa kale mu nsapato ndi minda ina, sizinagwiritsidwe ntchito pamlingo waukulu.vuto lalikulu la thovu lapamwamba kwambiri ndiloti mtengo womalizidwa ndi wotsika kwambiri, wosakwana 50%, motero umalepheretsa kukula kwa thovu lokwera kwambiri.
EVA idaphatikizidwa ndi ukadaulo wa 100% wobwezeretsedwanso wa Si-TPV wosinthira thovu la EVA, Ukadaulo wa thovu wa EVA uwu umathandizira kuyendetsa nsapato m'njira yabwino komanso yokhazikika.zomwe sizimangokwaniritsa kachulukidwe kakang'ono komanso kulimba mtima kwambiri komanso zimakhala ndi kukana kovala bwino, kuchepa kwa kutentha kwamafuta, mtundu wofananira, kuchuluka kwazinthu zomalizidwa, ntchito yosavuta, komanso mtengo wotsika, Yerekezerani ndi thovu lokwera kwambiri.
Pamene mafakitale ambiri ayamba kugwiritsa ntchito Soft EVA Foam Modifier Si-TPV iyi yosakanikirana ndi ukadaulo wa EVA, titha kuyembekezera kuwona kugwiritsa ntchito kwatsopano kwazinthu zatsopanozi.Zatsopano sizimangochitika pamakampani opanga nsapato zofewa kwambiri.
Ngati mukuyang'ana Flexible Soft EVA Foam material Solutions, Modifier imachepetsa kuponderezedwa kwa EVA thovu, Ukadaulo wotulutsa thovu wa Chemical wa thovu lopepuka la EVA, Soft EVA Foam Modifier kapena Solutions for supercritical thovu.
Chonde titumizireni, kuti mudziwe zambiri.
