Pepala lopangidwa ndi galvanized limatanthawuza mbale yokhuthala yachitsulo yokhala ndi zinki yokutidwa pamwamba.Hot-dip galvanizing ndi njira yachuma komanso yololera yolimbana ndi dzimbiri yomwe nthawi zambiri imasankhidwa.Pafupifupi theka la zinki zomwe zimapangidwa padziko lonse lapansi zimagwiritsidwa ntchito pochita izi.
Pepala lokongoletsedwa ndi kupewa dzimbiri pamwamba pa mbale wandiweyani zitsulo ndikuwonjezera moyo wake wautumiki.Pamwamba pa chitsulo chokhuthalacho chimakutidwa ndi chitsulo chachitsulo.Mtundu uwu wazitsulo wokutidwa ndi zinki umatchedwa galvanized sheet.
Malinga ndi njira zopangira ndi kukonza, zitha kugawidwa m'magulu otsatirawa:
① Mbale yachitsulo yotentha yoviyitsa yotentha.Chitsulo chozizira chozizira chimalowetsedwa mu bafa yosungunuka ya zinc, kotero kuti pamwamba pa pepala lozizira lozizira kwambiri limatsatiridwa ndi zinki.Panthawi imeneyi, chinsinsi ndi ntchito mosalekeza yotentha-kuviika galvanizing ndondomeko kupanga, ndiye wandiweyani zitsulo mbale mu mbale mosalekeza kumizidwa mu thanki plating ndi sungunuka zinki kupanga kanasonkhezereka pepala;
②Mapepala amalilala opangidwa bwino ndi tirigu.Mtundu uwu wazitsulo wandiweyani umapangidwanso ndi njira yothira yotentha, koma ikatuluka mu thanki, imatenthedwa mpaka pafupifupi 500 ° C kuti isinthe kukhala filimu ya pulasitiki ya aluminiyamu ya zinki ndi chitsulo.Mtundu uwu wa kanasonkhezereka pepala ali zomatira kwambiri zokutira zomangamanga ndi kuwotcherera magetsi;
③ Pepala lamagetsi lamagetsi.Kupanga kwa mtundu uwu wa pepala kanasonkhezereka ndi electroplating ali kwambiri ndondomeko ntchito.Komabe, zokutira ndizochepa thupi, ndipo kukana kwa dzimbiri sikwabwino ngati pepala lothirira lotenthetsera;
④Pepala lokhala ndi mbali imodzi komanso mbali ziwiri.Pepala lopangidwa ndi lambali limodzi komanso lambali ziwiri, ndiye kuti, katundu wotentha woviika amathiridwa mbali imodzi yokha.Pankhani ya kuwotcherera magetsi, kupopera mbewu mankhwalawa, odana ndi dzimbiri mankhwala, kupanga ndi processing, etc., izo ali amphamvu kusinthasintha kuposa awiri amaganiza kanasonkhezereka pepala.Pofuna kuchotsa chilema cha zinki wosatsekedwa kumbali zonse ziwiri, palinso mtundu wina wa pepala lopangidwa ndi chromatographic zinki kumbali inayo, ndiye kuti, pepala lopangidwa ndi malata losiyana mbali zonse;
⑤ Aluminiyamu aloyi, gulu kanasonkhezereka pepala.Amapangidwa ndi zinki ndi zida zina zachitsulo monga aluminiyamu, lead, zinki, ndi zina zambiri kuti apange ma aloyi a aluminiyamu kapena mbale zachitsulo zophatikizika.Mtundu uwu wa chitsulo wandiweyani mbale ali onse zodabwitsa odana ndi dzimbiri mankhwala ndi makhalidwe abwino kupopera mbewu mankhwalawa;
Kuwonjezera pamwamba asanu, palinso zokongola kanasonkhezereka pepala, chovala kusindikiza sprayed kanasonkhezereka pepala, polyethylene laminated kana kanasonkhezereka pepala ndi zina zotero.Koma pa nthawi imeneyi, ambiri akadali otentha-kuviika kanasonkhezereka pepala.
Chitsulo chosapanga dzimbiri ndi dzina lambiri la chitsulo chosapanga dzimbiri chosapanga asidi, chogonjetsedwa ndi zinthu zofooka monga gasi, nthunzi, madzi, kapena zitsulo zokhala ndi zitsulo zosapanga dzimbiri zimatchedwa mbale yachitsulo chosapanga dzimbiri;pamene zinthu zosagwirizana ndi zosungunulira (acid, alkali, mchere ndi zina organic chemical corrosion) ) zitsulo zokhazikika zimatchedwa zitsulo zosagwira asidi.
Chifukwa cha kusiyana kwa mitundu iwiriyi, kukana kwa dzimbiri kumasiyana.Nthawi zambiri, mbale zachitsulo zosapanga dzimbiri sizimamva dzimbiri, pomwe zitsulo zosamva asidi zimakhala ndi zitsulo zosapanga dzimbiri.Mawu oti "mbale zosapanga dzimbiri" samangotanthauza mtundu wa chitsulo chosapanga dzimbiri, komanso amawonetsa mitundu yopitilira 100 ya mbale zachitsulo zosapanga dzimbiri zopangidwa ndi mafakitale.Chimbale chilichonse chachitsulo chosapanga dzimbiri chomwe chimapangidwa ndikupangidwa chimakhala ndi mawonekedwe abwino kwambiri pazolinga zake zapadera.Chinsinsi cha kupambana ndikulingalira ntchito yoyamba, ndiyeno kalasi yoyenera yachitsulo.Nthawi zambiri pali zitsulo zisanu ndi chimodzi zokha zokhudzana ndi cholinga chachikulu cha zomangamanga.Onse ali ndi 17-22% chromium, ndipo magiredi abwino achitsulo alinso ndi faifi tambala.Kuonjezera molybdenum kumapangitsa kuti mpweya uziyenda bwino ndipo umalimbana kwambiri ndi mpweya wokhala ndi fluoride.
Chitsulo chosapanga dzimbiri chimatanthawuza chitsulo chomwe sichimamva dzimbiri zofooka monga gasi, nthunzi, ndi madzi, ndi zinthu zowononga zinthu monga asidi, alkali, ndi mchere, zomwe zimadziwikanso kuti chitsulo chosapanga dzimbiri cha asidi.Pazinthu zinazake, zitsulo zomwe zimagonjetsedwa ndi zinthu zofooka zowononga nthawi zambiri zimatchedwa zitsulo zosapanga dzimbiri, ndipo zitsulo zomwe zimagonjetsedwa ndi dzimbiri zosungunulira zimatchedwa chitsulo chosagwira asidi.Chifukwa cha kusiyana kwa mitundu iwiriyi, yoyambayo sikuti imalimbana ndi dzimbiri zosungunulira, pomwe yomalizayo nthawi zambiri imakhala yopanda banga.Kukana kwa dzimbiri kwa mbale zazitsulo zosapanga dzimbiri kumakhala muzinthu za aluminiyamu zomwe zili muzitsulozo.
