Kutentha-kuviika galvanizingndi njira yomwe chitsulo chachitsulo kapena gawo lomwe lili ndi malo oyera limamizidwa muzitsulo zosungunula za zinki, ndipo chitsulo chachitsulo chimapangidwira pamtunda kupyolera mwa thupi ndi mankhwala pa mawonekedwe.Hot-dip galvanizing, yomwe imadziwikanso kuti hot-dip galvanizing ndi kutentha-kuviika galvanizing, ndi njira yothandiza yachitsulo yolimbana ndi dzimbiri, yomwe imagwiritsidwa ntchito kwambiri polimbana ndi dzimbiri zazitsulo, zida ndi zida m'mafakitale osiyanasiyana.Ndiye makhalidwe ake ndi otaniotentha-kuviika kanasonkhezereka opanda chitsulo chitoliro?

1. Zigamba za imvi za kukula kosiyana pamwamba pa chitoliro chopanda chitsulo chosakanizidwa ndi kusiyana kwa mtundu wa galvanizing, womwe ndi vuto lovuta pamakampani opangira malata, makamaka okhudzana ndi kufufuza zinthu zomwe zili mu chitoliro chachitsulo chokha ndi zigawo zake. kusamba kwa zinc.Kuthimbirira sikumakhudza ntchito yotsutsana ndi dzimbiri ya chitoliro chachitsulo, kusiyana kokha kwa maonekedwe.

2. Pali pang'onopang'ono zoonekeratu anakweza zizindikiro pamwamba pa chilichonse kanasonkhezereka Msoko zitsulo chitoliro, amene onse nthaka, amene aumbike ndi kuzirala ndi kulimba kwa nthaka madzi oyenda pansi chitoliro chitoliro pambuyo kanasonkhezereka Msoko zitsulo chitoliro kuchotsedwa. zinc mphika.

4. Makasitomala ena adzagwiritsa ntchito polumikizira poyambira pogwiritsa ntchito chitoliro chachitsulo chosakanizidwa ndi malata kukanikizira poyambira.Chifukwa cha wandiweyani nthaka wosanjikiza wa otentha-kuviika kanasonkhezereka zitsulo chitoliro, pansi pa zochita zowononga kunja mphamvu, mbali ya kanasonkhezereka wosanjikiza adzasweka ndi peel, amene alibe chochita ndi khalidwe la kanasonkhezereka opanda zitsulo chitoliro lokha. .

5. Makasitomala ena amamva kuti patoli yachitsulo yopanda chitsulo pamakhala madzi achikasu (amadzimadziwa amatchedwa passivation fluid), omwe amatha kudutsa pamwamba pazitsulo.Nthawi zambiri ntchito pambuyo plating chithandizo cha kanasonkhezereka, cadmium ndi zokutira zina.Cholinga chake ndi kupanga mawonekedwe apamwamba pamwamba pa zokutira zomwe zingalepheretse kuchita bwino kwachitsulo, kupititsa patsogolo kukana kwa dzimbiri, ndikuwonjezera kukongola kwa mankhwala.Ikhoza kusintha kukana kwa dzimbiri kwa chitoliro chachitsulo ndikutalikitsa moyo wautumiki wa workpiece.

Kuteteza kwa wosanjikiza wothira-kuviika pamapaipi opanda chitsulo ndikwabwinoko kuposa utoto kapena pulasitiki.Pamene kutentha-kuviika galvanizing, nthaka diffused ndi chitsulo kupanga zinki-chitsulo intermetallic pawiri wosanjikiza, ndiko kuti, aloyi wosanjikiza.Aloyi wosanjikiza ndi metallurgically womangidwa zitsulo ndi zinki, amene ali wamphamvu kuposa chomangira utoto ndi zitsulo.Zosanjikiza zotentha za dip zimawonekera kumlengalenga ndipo sizigwa kwazaka zambiri mpaka zitachita dzimbiri mwachilengedwe.

Kutentha-kuviika galvanizing luso laChitoliro chachitsulo chosasinthikaAtha kugawidwa m'magawo a dip plating ndi kuwomba:

1. Dip plating.Kuziziritsa ndi madzi mwachindunji mutatha kuviika.Pafupifupi makulidwe a nthaka wosanjikiza ndi wamkulu kuposa ma microns 70, kotero mtengo wa galvanizing ndi wokwera, ndipo kuchuluka kwa zinki ndi kwakukulu.M'malo abwinobwino am'mlengalenga kwa zaka zopitilira 50, pali zowoneka bwino zakuyenda kwa zinki, ndipo chitoliro chachitsulo chotalika kwambiri chopanda msoko chimatha kuyikidwa mpaka 16m.

2. Kuwomba plating.Pambuyo pa malata, kunja kumawombedwa ndipo mkati mwake mumazizira.Wapakati makulidwe a zinki wosanjikiza ndi wamkulu kuposa 30 ma microns, mtengo wake ndi wotsika, ndipo zinc kumwa ndi kochepa.Pambuyo pazaka zopitilira 20 zogwiritsidwa ntchito m'malo abwinobwino am'mlengalenga, palibe ngakhale pang'ono zamadzimadzi za zinki zomwe zimawonedwa.General kuwombedwa zinki kupanga mzere 6-9m.
