Hot-dip galvanizing ndi njira yodziwika bwino yotetezera dzimbiri lachitsulo.Imamiza zinthu zachitsulo mumadzi osungunuka a zinki kuti apange gawo la aloyi ya zinc-iron ndi wosanjikiza wa zinc wangwiro pamwamba pa chitsulocho, motero amapereka chitetezo chabwino cha dzimbiri.Njira imeneyi chimagwiritsidwa ntchito yomanga, galimoto, mphamvu, kulankhulana ndi mafakitale ena kuteteza nyumba zitsulo, mapaipi, fasteners, etc.
Njira zoyambira za hot dip galvanizing ndi izi:
Degreasing ndi kuyeretsa
Chitsulo choyamba chiyenera kutsukidwa bwino kuti chichotse mafuta, dothi ndi zonyansa zina.Izi kawirikawiri zimachitika mwa kumiza chitsulo mu njira ya alkaline kapena acidic kenako ndikutsuka madzi ozizira.
Kupaka kwa flux
Chitsulo chotsukidwacho chimamizidwa mu 30% zinc ammonium solution pa 65-80.°C.Cholinga cha sitepeyi ndikugwiritsa ntchito chingwe chachitsulo chothandizira kuchotsa ma oxides pamwamba pa chitsulo ndikuonetsetsa kuti zinc yosungunuka imatha kuchita bwino ndi chitsulocho.
Galimoto
Chitsulocho chimamizidwa mu zinc wosungunuka pa kutentha pafupifupi 450°C. Nthawi yomiza nthawi zambiri ndi mphindi 4-5, malingana ndi kukula kwake ndi inertia yotentha yachitsulo.Panthawi imeneyi, chitsulo pamwamba pake chimakhala ndi zinki wosungunuka.
Kuziziritsa
Pambuyo pa galvanizing yotentha, chitsulocho chiyenera kukhazikika.Kuziziritsa kwachilengedwe kwa mpweya kapena kuzizira kofulumira ndikuzimitsa kungasankhidwe, ndipo njira yeniyeni imadalira zofunikira zomaliza za chinthucho..
Hot-dip galvanizing ndi njira yabwino yothanirana ndi dzimbiri pazitsulo, kupereka zopindulitsa zazikulu:
●Mtengo wotsika: Mtengo woyambira komanso wanthawi yayitali wa galvanizing wa dip-dip nthawi zambiri umakhala wotsika kuposa zokutira zina zoletsa dzimbiri, zomwe zimapangitsa kusankha kotsika mtengo.
●Moyo wautali wautumiki: Chophimba cha malata chimatha kuteteza chitsulo mosalekeza kwa zaka zopitilira 50 ndikukana dzimbiri.
●Kukonza pang'ono kumafunika: Popeza kuti zokutira zokhala ndi malata zimadzisamalira komanso zokulirapo, zimakhala ndi ndalama zochepa zosamalira komanso moyo wautali wautumiki.
●Zimateteza zokha madera owonongeka: Chophimba cha malata chimapereka chitetezo cha nsembe, ndipo madera ang'onoang'ono owonongeka safuna kukonzanso kwina.
●Chitetezo chokwanira komanso chathunthu: Kuthira madzi otentha kumatsimikizira kuti mbali zonse, kuphatikizapo madera ovuta kufika, ndizotetezedwa mokwanira.
●Kuwunika kosavuta: Mkhalidwe wa zokutira zamagalasi ukhoza kuwunikidwa ndi kuyang'ana kosavuta.
●Kuyika mwachangu:Zogulitsa zazitsulo zotentha zotentha zimakhala zokonzeka kugwiritsidwa ntchito zikafika pamalo ogwirira ntchito, popanda kukonzekera kapena kuyang'anitsitsa.
● Kugwiritsa ntchito mwachangu zokutira zonse: Njira yopangira galvanizing yotentha ndi yofulumira komanso yosakhudzidwa ndi nyengo, kuonetsetsa kutembenuka mwamsanga.
Ubwino umenewu umapangitsa kuti galvanizing yotentha ikhale yabwino kwambiri yotetezera dzimbiri, zomwe sizimangowonjezera moyo wautumiki ndi ntchito yachitsulo, komanso zimachepetsanso ndalama zonse komanso ntchito yokonza.
Mawonekedwe owonekera a kumapeto (kuphatikiza nkhope za flange) zaCDSR kuyamwa mafuta ndi kutulutsa ma hosesTS EN ISO 1461 (TS EN ISO 1461): Kuzimbiri komwe kumadza chifukwa cha madzi a m'nyanja, nkhungu yamchere ndi njira yotumizira mauthenga.Pamene makampani amafuta ndi gasi akupitilizabe kupititsa patsogolo chitukuko chokhazikika, kugwiritsa ntchito ukadaulo wotenthetsera wothira mafuta sikuti kumangowonjezera kukana kwa dzimbiri komanso kumawonjezera moyo wake wautumiki, komanso kumachepetsa kugwiritsa ntchito zida ndikuwononga zinyalala pochepetsa kuchuluka kwa zida m'malo. chifukwa cha dzimbiri.
