Galvanizing amatanthauza pamwamba mankhwala luso plating wosanjikiza nthaka pamwamba pa chitsulo, aloyi kapena zinthu zina kusewera zokongoletsa ndi dzimbiri kupewa effect.The njira yaikulu ntchito ndi otentha-kuviika galvanization.
Zinc imasungunuka mosavuta mu ma acid komanso alkali, motero imatchedwa chitsulo cha amphotropic. Zinc imasintha pang'ono mumpweya wowuma. Mu mpweya wonyowa, filimu yowundana ya zinc carbonate imapangidwa pamwamba pa nthaka. hydrogen sulfide ndi Marine m'mlengalenga, nthaka dzimbiri kukana ndi osauka, makamaka kutentha ndi mkulu chinyezi munali organic acid m'mlengalenga, nthaka ❖ kuyanika n'zosavuta dzimbiri. Muyezo wa elekitirodi kuthekera nthaka ndi-0.76V, kwa masanjidwewo zitsulo, nthaka ❖ kuyanika ndi wa anodic ❖ kuyanika, izo makamaka ntchito kupewa dzimbiri zitsulo, ntchito zake zoteteza ndi makulidwe ❖ kuyanika ndi kwambiri zokhudzana.Zinc ❖ kuyanika pambuyo mankhwala passivation, kudetsa kapena yokutidwa ndi kuwala zoteteza wothandizila, akhoza kwambiri patsogolo chitetezo chake ndi kukongoletsa.
Kuzizira galvanizing
Cold galvanizing, yomwe imatchedwanso electrogalvanizing, ndikugwiritsa ntchito zida za electrolytic pambuyo pa mafuta, pickling, mchere wa zinki mu yankho, ndikugwirizanitsa electrode yolakwika ya zida za electrolytic, mosiyana ndi mbale ya zinki, yolumikizidwa ndi electrode yabwino ya electrolytic. zida mphamvu, ntchito panopa kuchokera zabwino kuti zoipa adzaika wosanjikiza nthaka pa chitoliro, ozizira plating chitoliro choyamba processing pambuyo galvanizing.
Zimango kanasonkhezereka
Mu ng'oma yozungulira yokhala ndi plating, mpira wagalasi, ufa wa zinki, madzi ndi zolimbikitsa, mpira wagalasi ngati sing'anga umasinthasintha ndi ng'oma, kukangana ndi nyundo pamwamba pa plating kumatulutsa mphamvu zamakina.Pansi pa zochita za mankhwala olimbikitsa, yokutidwa zinki ufa "kuwotcherera ozizira" kwa ❖ kuyanika pamwamba, kupanga yosalala, yunifolomu ndi mwatsatanetsatane zokutira ndi makulidwe enaake.
Hot-galvanized
Njira yayikulu yokometsera zitsulo zam'mwamba ndikuyika galvanizing yotentha.
Kupaka malata otentha kunapangidwa kuchokera ku njira zakale ndipo ndi zaka zana limodzi ndi makumi asanu ndi awiri kuchokera pamene adagwiritsidwa ntchito m'makampani mu 1836. m'zaka makumi atatu zapitazi.
The ndondomeko yopanga otentha kanasonkhezereka mbale makamaka zikuphatikizapo: choyambirira mbale chisanadze plating otentha kuviika pambuyo mankhwala anamaliza mankhwala anayendera, etc.According ndi chizolowezi, malinga ndi njira zosiyanasiyana plating mankhwala, ndi yotentha kuviika galvanizing ndondomeko anawagawa kunja mzere. ndi kulowa mkati mwa mzere annealing.
