Matambudziko ezvakatipoteredza ari kuramba achionekwa zvakanyanya sekukura kwehupfumi, uye kuwana makemikari anobatsira pakuchengetedza nharaunda ibasa guru mazuva ano.
Tekinoroji yefuro rinopenya zvikuru (Supercritical foam) tekinoroji itsva inochinja-chinja, zvinhu zvinofema furo zvinoshandiswa mutekinoroji yefuro rinopenya zvikuru (Supercritical foam agents) zvinowanzova carbon dioxide inopenya zvikuru (ScCO2).2) uye supercritical nitrogen (ScN)2), ese ari maviri anoshandiswa pasina mutoro wezvakatipoteredza.
Mukushandiswa kweshangu, Supercritical Foam Technology iri kuchinja indasitiri yeshangu. Iyi tekinoroji yakabvumira vagadziri veshangu kuwedzera mhando dzezvinhu zvavo kupfuura TPU, TPE, neEVA yechinyakare. Iye zvino, vanogona zvakare kushandisa zvinhu zvakaita sePEBAX, ETPU, nedzimwe elastomers kugadzira shangu dzine cushion uye rutsigiro rwakanaka, asi dzakareruka, dzakasimba, dzakasununguka, uye dzisingakuvadzi nharaunda.
Asi nekushandisa tekinoroji ye supercritical furo kugadzira furo reEVA kwakachinja mashandisiro anoita maindasitiri mazhinji chinhu ichi. Iyi tekinoroji inoshandisa musanganiswa wekumanikidzwa kwakanyanya uye tembiricha kugadzira furo rakareruka, rinogara kwenguva refu, uye rinodzivirira kubvaruka. Maitiro acho anosanganisira kuisa gasi, senge carbon dioxide (ScCO2).2), mumvura inogadziriswa neEVA resin nezvimwe zvinowedzerwa. Gasi rinozopiswa uye rinomanikidzwa kusvika rasvika padanho repamusoro-soro, izvo zvinoita kuti gasi rikure nekukurumidza uye rigadzire mabubble madiki. Mabubble aya anobva avharirwa mumushonga unogadziriswa, zvichigadzira furo rine hunhu hwakanaka kana tichienzanisa nemafuro echinyakare. Rinokurumidza, rakareruka, rakasimba, uye rinogara kwenguva refu, zvichiita kuti rive sarudzo yakakodzera kune akasiyana mashandisirwo. Semuenzaniso, kubva kushangu inopa cushion uye rutsigiro rwetsoka kusvika kuzvigadzirwa zvehutsanana, zvigadzirwa zvemitambo, machira epasi/yoga, matoyi, kurongedza, zvishandiso zvekurapa, zvishandiso zvekudzivirira, zvigadzirwa zvisingatsvedzeri mvura, mapaneru ephotovoltaic, nezvimwewo... Rinoshandiswawo muzvishandiso zvemotokari nendege kupa insulation uye kudzivirira ruzha.
Tekinoroji Dzinochengetedza Zvinhu Zvekugadzira Zvinhu Zvakagadzirwa neEVA Furo!
Zvisinei, kushandiswa kwetekinoroji ye supercritical foam kugadzira zvinhu zveEVA kunoda kutariswa panyaya ye cross-linking. EVA molecular chains i linear uye inoda chimiro chakabatana kuti ivhare gasi. Kunyangwe iri kugadzirwa mushangu nedzimwe nzvimbo, haisati yashandiswa zvakanyanya. Dambudziko guru re supercritical foam nderekuti chiyero chechigadzirwa chapera chakaderera zvakanyanya, chiri pasi pe50%, nokudaro zvichideredza kukura kwe supercritical foam.
EVA yakasanganiswa netekinoroji yeSi-TPV inodzokororwa 100% yekugadzira furo yeEVA, tekinoroji iyi yefuro yeEVA inobatsira kufambisa shangu munzira yakasununguka uye inogara kwenguva refu. Izvo hazvingogone chete kuwana density yakaderera uye yakasimba asi zvakare zvine resistance yakanaka yekupfeka, thermal shrinkage rate yakaderera, ruvara rwakafanana, chigadzirwa chakagadzirwa chakakwira, nyore kushanda, uye mutengo wakaderera, Enzanisa ne supercritical furo.
Sezvo maindasitiri akawanda achitanga kushandisa iyi Soft EVA Foam Modifier Si-TPV yakasanganiswa netekinoroji yeEVA, tinogona kutarisira kuona kushandiswa kwakawanda kwezvinhu zvitsva izvi. Kutsva hakugumiri muindasitiri yemasneaker akapfava elastic.
Kana uchitsvaga Flexible Soft EVA Foam material Solutions, Modifier inoderedza kudzvanywa kweEVA foaming, Chemical foaming technology yeEVA foam yakareruka, Soft EVA Foam Modifier kana Solutions yesupercritical foaming.
Ndapota taurai nesu, kuti mudzidze zvakawanda.
