Mavuto azachilengedwe akuchulukirachulukira pamene chitukuko cha zachuma chikuchulukirachulukira, ndipo kukwaniritsa njira zobiriwira ndi ntchito yofunika kwambiri masiku ano.
Ukadaulo wa thovu wovuta kwambiri ndi ukadaulo watsopano wosintha zinthu, zinthu zotulutsa thovu zomwe zimagwiritsidwa ntchito muukadaulo wa thovu wovuta kwambiri nthawi zambiri zimakhala carbon dioxide wovuta kwambiri (ScCO2).2) ndi supercritical nitrogen (ScN)2), zonse ziwiri zimagwiritsidwa ntchito popanda vuto la chilengedwe.
Mu ntchito za nsapato, Supercritical Foam Technology ikusinthiratu makampani opanga nsapato. Ukadaulo uwu walola opanga nsapato kukulitsa mitundu yawo ya zinthu kupitirira TPU, TPE, ndi EVA yachikhalidwe. Tsopano, angagwiritsenso ntchito zipangizo monga PEBAX, ETPU, ndi ma elastomer ena kuti apange nsapato zokhala ndi cushion komanso chithandizo chabwino kwambiri, pomwe zimakhala zopepuka, zolimba, zomasuka, komanso zosawononga chilengedwe.
Koma pogwiritsa ntchito ukadaulo wopangira thovu la EVA, mafakitale ambiri amagwiritsa ntchito thovu la EVA. Ukadaulo uwu umagwiritsa ntchito kuphatikiza kwa kuthamanga kwambiri ndi kutentha kuti apange thovu lopepuka, lolimba, komanso losawonongeka kwambiri. Njirayi imaphatikizapo kubaya mpweya, monga carbon dioxide (ScCO2).2), mu yankho lamadzimadzi la utomoni wa EVA ndi zina zowonjezera. Mpweyawo umatenthedwa ndi kukakamizidwa mpaka utafika pamlingo wofunikira kwambiri, zomwe zimapangitsa kuti mpweyawo ukule mofulumira ndikupanga thovu laling'ono. Thovu limeneli limagwidwa mu yankho lamadzimadzi, zomwe zimapangitsa thovu lomwe lili ndi mphamvu zabwino poyerekeza ndi thovu lachikhalidwe. Ndi lachangu, lopepuka, lolimba, komanso lolimba, zomwe zimapangitsa kuti likhale chisankho chabwino kwambiri pa ntchito zosiyanasiyana. Mwachitsanzo, kuyambira nsapato zimapereka chithandizo cha mapazi mpaka zinthu zaukhondo, zinthu zosangalatsa zamasewera, mphasa zapansi/yoga, zoseweretsa, ma CD, zida zachipatala, zida zodzitetezera, zinthu zosatsetsereka m'madzi, mapanelo a photovoltaic, ndi zina zambiri... Imagwiritsidwanso ntchito mu ntchito zamagalimoto ndi zamlengalenga kuti ipereke kutchinjiriza ndi kuteteza mawu.
Ukadaulo Wokhazikika wa Zinthu Zatsopano zopangidwa ndi thovu la EVA!
Komabe, kugwiritsa ntchito ukadaulo wa supercritical thovu popanga zinthu za EVA kumafuna chisamaliro pankhani yolumikizana. Maunyolo a mamolekyu a EVA ndi olunjika ndipo amafunika kapangidwe kolumikizana kuti atseke mpweya. Ngakhale kuti ukupangidwa kale mu nsapato ndi madera ena, sunagwiritsidwe ntchito kwambiri. Vuto lalikulu la supercritical thovu ndikuti kuchuluka kwa chinthu chomalizidwa ndi kochepa kwambiri, kochepera 50%, motero kumachepetsa kukula kwa supercritical thovu.
EVA idasakanizidwa ndi ukadaulo wa thovu la EVA wobwezeretsanso wa Si-TPV 100%, ukadaulo wa thovu la EVA uwu umathandiza kuyendetsa nsapato m'njira yabwino komanso yokhazikika. Izi sizimangopangitsa kuti zikhale zochepa komanso zolimba komanso zimakhala ndi kukana kwabwino kwambiri kuwonongeka, kuchepa kwa kutentha, mtundu wofanana, kuchuluka kwa zinthu zomalizidwa bwino, kugwiritsa ntchito mosavuta, komanso mtengo wotsika, Yerekezerani ndi thovu lofunika kwambiri.
Pamene mafakitale ambiri akuyamba kugwiritsa ntchito Soft EVA Foam Modifier Si-TPV yosakanikirana ndi ukadaulo wa EVA, tikuyembekeza kuwona kugwiritsa ntchito kwatsopano kwambiri pazinthu zatsopanozi. Zatsopano sizimangogwiritsidwa ntchito kokha ndi makampani opanga nsapato zofewa zofewa.
Ngati mukufuna Flexible Soft EVA Foam Material Solutions, Modifier imachepetsa kupsinjika kwa EVA foam, Chemical thovu technology ya thovu lopepuka la EVA, Soft EVA Foam Modifier kapena Solutions ya supercritical thovu.
Chonde titumizireni uthenga, kuti mudziwe zambiri.
