The Choyambira choteteza dzimbiri chomwe chimagwiritsidwa ntchito kwambiri popewa dzimbiri pa kapangidwe ka chitsulo ndi choyambira chokhala ndi epoxy zn yokhala ndi chitetezo cha cathodic. Utotowu sumangokhala ndi mphamvu yolimba yolumikizira pamwamba pa chitsulo chosungunuka, komanso umakhala ndi kukana dzimbiri komanso magwiridwe antchito okwera mtengo. Chifukwa cha kuchuluka kwa chikondi cha anthu, umagwiritsidwa ntchito kwambiri pamitundu yonse yaukadaulo woteteza dzimbiri pa kapangidwe ka chitsulo.

Monga primer ya zigawo ziwiri yolimbana ndi dzimbiri, primer yokhala ndi epoxy zinc yambiri ili ndi mphamvu zabwino kwambiri zotsutsana ndi dzimbiri, kumatira, mphamvu zamakanika komanso mphamvu zothandizira. Ndi yoyenera chitsulo chotsutsana ndi dzimbiri mumlengalenga, ndipo imagwiritsidwa ntchito kwambiri polimbana ndi dzimbiri, mlengalenga wa mankhwala, chilengedwe cha m'madzi ndi zina zotsutsana ndi dzimbiri komanso zophimba nyengo, monga: Kapangidwe ka chitsulo cha zomera, Milatho ikuluikulu, makina olowera, makina olemera, migodi yamafuta ndi zida zamigodi, mapaipi obisika, thanki yosungiramo mafuta khoma lakunja, thanki yamafuta khoma lakunja ndi chombo ndi denga pamwamba pa mzere wamadzi ndi kapangidwe kachitsulo kamakina olemera olimbana ndi dzimbiri.

choyambira chokhala ndi epoxy zinc

Utoto wolemera ndi zinc ukagwiritsidwa ntchito pa pulayimale ya mlatho wachitsulo, pulayimale yakunja yosungiramo zinthu yoletsa kuwononga, utoto woletsa kuwononga kunja kwa chidebe, utoto woletsa kuwononga mkati mwa chitsulo, pulayimale ya chipolopolo cha sitima, njira yotetezera kuwononga kuwononga ndi malo ena ozungulira mlengalenga, ndikofunikira kusankha njira yothandizira yoyenera, ndikugwiritsa ntchito kapangidwe kofanana ka utoto woyambira pakati kuti mukwaniritse cholinga choteteza gawo lapansi kwa nthawi yayitali. Kawirikawiri, njira yophikira ya pulayimale yolemera ndi zinc + epoxy iron + acrylic polyurethane topcoat ndi yayikulu kwambiri.

Mu ndondomeko yeniyeni yogwiritsira ntchito, kuchuluka kwa utoto ndi chotsukira ziyenera kukhala mogwirizana ndi zofunikira za wopanga, ndipo chosungunula chapadera chomwe chimagwiritsidwa ntchito, njira yotsukira yomwe imagwiritsidwa ntchito kwambiri ndi kupopera mpweya, kupopera popanda mpweya, kuphimba burashi, ndi zina zotero, malinga ndi mawonekedwe a kapangidwe ka chitsulo, malo ndi zosankha zina zomveka, makulidwe a kutsuka filimu ya utoto ayenera kulamulidwa pa 70-80μm kuti akwaniritse zotsatira zabwino zotsutsana ndi dzimbiri.

Mu nkhani yomwe ili pamwambapa, tikuyambitsa njira yophikira yomwe imagwiritsidwa ntchito kwambiri. Pogwira ntchito ya njira yophikirayi, tiyenera kuonetsetsa kuti utoto wapakati ukatha, utoto wapakati umapakidwa utoto patatha maola 24. Utoto wapakati sumangokhala ndi kumatirira bwino, kuletsa dzimbiri, kuteteza komanso kukhuthala, komanso umakulitsa makulidwe onse a filimu ya utoto ndikuwonjezera mphamvu yoletsa dzimbiri. Kukhuthala kwa filimuyi kumatha kupopedwa mpaka 100-150μm kuti ukwaniritse makulidwe a filimu yomwe yatchulidwa.

Utoto wapakati ukatha, utoto wa acrylic polyurethane topcoat umayikidwa pa maola 24. Utoto wa pamwamba ndi utoto woteteza ku kuzizira kwambiri womwe umalimbana ndi nyengo, asidi ndi alkali, filimu yolimba komanso zokongoletsera zabwino. Kudzera mu chitetezo cha utoto wapamwamba, utoto wa epoxy pansi umapewedwa ndi kuwala kwa ultraviolet ndi ufa, ndipo umapereka chitetezo champhamvu komanso zokongoletsera.
