Hot-dip galvanizing, ho ke ke mocheso phahameng zinki ingots qhibiliha, ho behoa ka lintho tse thusang, ka nako eo sebopeho tšepe e qoelisoa ka zinki plating bath, e le hore setho sa tšepe khomaretse lera ka lera zinki.Molemo o chesang oa galvanized o itšetlehile ka bokhoni ba oona ba ho boloka, ho molemo ho khomarela le ho thatafala ha lera la galvanized.

Cold galvanizing ke zinki letsoai tharollo ka electrolysis, ho plating ka barbotage, ka kakaretso, tse se nang futhumatsang, palo ea zinki ka seoelo kopana le mongobo tikoloho bonolo haholo ho oa theoha.The batang galvanizing phekolo ea 'mele, feela ka holim'a borashe mposo ya zinki, zinki barbotage ho le bonolo ho oela theoha tshebediso ya chesang-ina galvanized kaho.

Mokhoa oa ho kenya galvanizing e chesang le e batang

Hot dip galvanized e qoelisoa ka zinki mokelikeli qhibiliha workpiece degreasing, pickling, dipping, omisa nako e itseng ea nako le ho beha pele.

Cold galvanizing, eo hape e bitsoang electro-galvanized, ke tšebeliso ea sesebelisoa sa electrolysis ho workpiece ho hlophisoa ha tharollo ea letsoai ea zinki, ka mor'a ho senya, ho khetha, le ho hokahanya electrode e mpe ea sesebelisoa sa electrolytic;zinki poleiti e behiloeng ka lehlakoreng le leng la workpiece e hoketsoe ka sesebediswa electrolytic eleketrode positive, matla a buletsoe, hona joale ho tloha eleketrode positive ho ea motsamao o fosahetseng directional, e tla behoa holim'a workpiece le lera la zinki. .

Ponahalo ya ho tjheseha ha metsi a chesang le a batang

Cold galvanizing shebahala ho feta boreleli, e khanyang, 'mala passivation thulaganyo plating lera ke mosehla botala ka' mala, e ne e mebala-bala.Plating layer e ne e le bosoeu bo boputsoa kapa bo bosoeu ka mokhoa o mosoeu oa passivation o ne o le o motala, o mosoeu oa ho roala 'me letsatsi le ne le le bohlokoa.Likarolo tse rarahaneng tsa li-angular li na le "ho chesoa ha motlakase" ho tloha lefifing, likarolo tsa lesela la zinc.Sebaka sa sekhutlo sa Yin se bonolo ho theha sebaka sa morao-rao sa bohlooho se shoeleng mme sebaka sa zinki se tšesaane.The workpiece kakaretso zinki hlahala, caking phenomenon.

Hot qoelisa galvanized shebahala e nyenyane kaba bapisoa le electro-galvanized, silevera e tšoeu, sheba le tšekamelo ea ho tshebetso waterlines le marotholi a seng makae a hlahala e totobetse haholoanyane, haholo-holo qetellong e 'ngoe ea workpiece.Hot dip galvanized zinki lera ho feta makhetlo a 'maloa a eleketro-galvanized teteaneng tshireletso ya corrosion ke makhetlo a' maloa ho feta ea electro-galvanized.
