eva thovu mat zakuthupi Mbali ndi zisamaliro

Makatani a thovu a EVA akhala akugwiritsidwa ntchito kwambiri pantchito ndi moyo, ndipo amatha kuwoneka m'nyumba, m'malo, kumalo ochitira masewera olimbitsa thupi ndi malo ena.Kupanga zinthu za EVA pogwiritsa ntchito mphasa zapansi kumakhala ndi zabwino zambiri.Mwachitsanzo: kukana kugwedezeka kwabwino, madzi, umboni wamagetsi, etc. Tiuzeni za zipangizo za EVA.

Makhalidwe a EVA thovu pansi mphasa:
        Kukana madzi:Ma cell osalowa mpweya, osayamwa madzi, kukana chinyezi, komanso kukana madzi abwino.
        Kulimbana ndi corrosion:kugonjetsedwa ndi dzimbiri za mankhwala monga madzi a m'nyanja, mafuta, asidi, alkali, antibacterial, non-poizoni, osanunkhiza, komanso opanda kuipitsa.
        Kuthekera:Palibe zolumikizira, komanso zosavuta kukonza monga kukanikiza kotentha, kudula, gluing, ndi kulumikizana.
        Anti-vibration:kulimba mtima kwakukulu komanso kudana ndi kupsinjika, kulimba kwambiri, kutsimikizika kodabwitsa komanso kuchita bwino.
        Thermal Insulation:Kutentha kwabwino kwambiri, kuteteza kuzizira komanso kutentha pang'ono, ndipo kumatha kupirira kuzizira kwambiri komanso kukhudzidwa.
        Kutsekereza mawu:cell yopanda mpweya, mphamvu yabwino yotchinjiriza mawu.

Pamene zomwe zili mu vinyl acetate mu EVA ndizochepera 20%, zitha kugwiritsidwa ntchito ngati pulasitiki.EVA ili ndi kukana kwabwino kwa kutentha kochepa.Kutentha kwake kowola ndikotsika, pafupifupi 230 ° C.Pamene kulemera kwa mamolekyu kumawonjezeka, malo ochepetsetsa a EVA amawonjezeka, ndipo kusinthika ndi kung'anima kwa zigawo zapulasitiki kumachepa, koma mphamvu zimawonjezeka ndi kukhudza Kulimba ndi kusagwirizana kwa chilengedwe kumawonjezeka.Kukaniza kwa mankhwala ndi kukana kwa mafuta a EVA ndi koipa pang'ono kusiyana ndi PE ndi PVC, ndipo kusintha kumaonekera kwambiri ndi kuwonjezeka kwa vinyl acetate content.
Poyerekeza ndi PE, ntchito ya EVA imapangidwa bwino, makamaka ponena za elasticity, kusinthasintha, gloss, mpweya permeability, etc. Kuphatikiza apo, kukana kwake kusokoneza kusokonezeka kwa chilengedwe kwakhala bwino, ndipo kulekerera kwake kwa fillers kwawonjezeka.Ikhoza kugwiritsidwa ntchito ndi zowonjezera zowonjezera zowonjezera.Njira zopewera kapena kuchepetsa kuwonongeka kwa zinthu zamakina a EVA kuposa PE.EVA imathanso kusinthidwa kuti mupeze mapulogalamu atsopano.Kusintha kwake kungaganizidwe kuchokera kuzinthu ziwiri: imodzi ndiyo kugwiritsa ntchito EVA monga msana wolumikiza ma monomers ena;ina ndi kumwa mowa pang'ono EVA.

EVA mat chithandizo ndi chisamaliro
        Njira yozimitsa moto:ozimitsa moto ayenera kuvala masks gasi ndi zovala zonse zozimitsa moto, ndi kuzimitsa moto ku mbali ya mphepo.Chozimitsa: nkhungu yamadzi, thovu, ufa wouma, mpweya woipa, nthaka yamchenga.
        Chithandizo chadzidzidzi:Patulani malo omwe atayipitsidwa ndikuletsa kulowa.Dulani gwero la moto.Ndikofunikira kuti ogwira ntchito pamwadzidzidzi azivala zomangira fumbi (zophimba nkhope zonse) ndi masuti oteteza mpweya.Pewani fumbi, sesani mosamala, ikani m'thumba ndikusamutsira pamalo otetezeka.Ngati pali kutayikira kochuluka, sonkhanitsani kuti muugwiritsenso ntchito kapena muwatengere kumalo otaya zinyalala kuti akatayidwe.
        Chidziwitso cha Ntchito:Kugwira ntchito mopanda mpweya, kumapereka mpweya wabwino wachilengedwe.Ogwira ntchito ayenera kuphunzitsidwa mwapadera ndikutsata ndondomeko zoyendetsera ntchito.Ndibwino kuti ogwira ntchito azivala zopumira fumbi zodzipangira okha, magalasi oteteza mankhwala, zovala zodzitchinjiriza ndi magolovesi amphira.Khalani kutali ndi magwero a moto ndi kutentha, ndipo kusuta ndikoletsedwa kuntchito.Gwiritsani ntchito makina opumira ndi mpweya wosaphulika.Pewani kupanga fumbi.Pewani kukhudzana ndi okosijeni ndi alkalis.Pogwira, tsitsani ndikutsitsa mosamala kuti mupewe kuwonongeka kwa zotengera ndi zotengera.Zokhala ndi mitundu yofananira ndi kuchuluka kwa zida zozimitsa moto ndi zida zadzidzidzi zomwe zatuluka.Zotengera zopanda kanthu zitha kukhala zotsalira zowononga.
        Zosungirako:Sungani m'nyumba yosungiramo zinthu zoziziritsa kukhosi komanso mpweya wabwino.Khalani kutali ndi gwero la moto ndi kutentha.Iyenera kusungidwa mosiyana ndi zowonjezera zowonjezera ndi zamchere, ndipo pewani kusungirako kosakanikirana.Okonzeka ndi mitundu yoyenera komanso kuchuluka kwa zida zozimitsa moto.Malo osungiramo ayenera kukhala ndi zipangizo zoyenera kuti zikhale ndi kutayikira.
Muzokongoletsa ndi zokongoletsera, ngati musankha zinthu za EVA ngati zinthu zapamphasa, mutha kugwiritsa ntchito mwanzeru zinthu zatsopanozi mwa kulabadira zovuta zomwe tafotokozazi.Ogula sayenera kuiwala mtundu ndi malonda ake pambuyo pogula zinthu.Ichinso ndiye chinsinsi cha zipangizo.
