Galvanized terata barbotage kaba, passivation filimi ha e khanyang, bath mocheso o phahameng haholo.Haeba sets'oants'o sa cathode hajoale se le holimo haholo, zinki ka bateng e phahame haholo kapa sodium hydroxide le DPE e tlase haholo;Likaroloana tse tiileng kapa litšila tse feteletseng tsa tšepe tsa kantle ho tharollo ea electroplating li ka baka mathata a joalo.Tharollo: Haeba barbotage e khōlōterata e entsoeng ka masenkee mahoashe, ho ka 'na ha e-ba le likaroloana tse tiileng ka har'a tharollo ea plating.Haeba ho thatafala ha karolo e boima, boima ba hona joale bo ka ba bo phahameng haholo.
Haeba zinki barbotage e ntle, empa ka 3% asiti nitric ha leseli, barbotage na le moriti o lefifi, passivation etsahala ha filimi e sootho, ka 'na bakoa ke litšila tse tsoang linaheng tse ling tse kang koporo kapa loto ka mokelikeli galvanizing.Ha mathata a hlaha ka tshebetso ya ho galvanizing kholo khoeleterata e entsoeng ka masenke, mocheso le boima ba hona joale li hlahlojoa pele, ebe litaba tsa zinki le sodium hydroxide ka tharollo ea plating li lekanngoa le ho lokisoa ka ho hlahloba tharollo ea ho pata.Hore na litaba tsa DPE li tlase ho ka khethoa ka tlhahlobo ea lisele tsa mmele.
Haeba ho roala roughness e sa bakoe ke mabaka a ka holimo, e ka 'na ea bakoa ke litšila ka tharollo plating.E ka nka tekanyo e nyane ea tharollo ea electroplating, tlhahlobo ea filtration, ebe o nka tharollo e nyane ea electroplating, ka kalafo ea phofo ea zinki kamora tlhahlobo, hlahloba bothata ke likaroloana tse tiileng kapa koporo, loto le litšila tse ling tsa tšepe tse tsoang kantle ho naha.Ka bonngoe, ha ho thata ho fumana sesosa sa bothata.Tepo ea tšepe e entsoeng ka masenkeho roala blister, ho se mamelle hantle.
Phekolo e mpe pele ho plating;Mocheso oa ho hlapa o tlase haholo;Boleng bo bobe ba li-additives kapa li-additives tse ngata haholo le litšila tsa tlhaho li tla baka maqhama a fokolang.Boleng ba li-additives bo boetse bo na le phello ea ho roala foaming.Li-additives tse ling li sebetsa ka mokhoa o sa phethahalang nakong ea ho kopanya 'me li tsoela pele ho polymerize nakong ea polokelo ea nako e telele kapa tšebeliso.Tlatsetso e na le tšekamelo ea ho sotha kristale lattice mme e baka khatello ea maikutlo, e leng se etsang hore seaparo se phomole.
Ha ho koaheloa ha kholoterata e entsoeng ka masenkee blistered ha ho etsoa galvanizing, mocheso oa ho hlapa o lokela ho hlahlojoa pele.Haeba mocheso oa ho hlapa ha o tlaase, ebe o matlafatsa ho tlosoa ha oli pele ho plating, ho thibela tšepe ea motheo ka kutu ea acid.Haeba u ela hloko mathata ana, ts'ebetso ea bubbling e ntse e le teng, e lokela ho ela hloko litekanyetso le boleng ba li-additives, joale u ka khaotsa ho eketsa li-additives, ka nako e telele ea electrolysis ea nako e telele, ho fokotsa litaba tsa li-additives, hlokomela hore na ts'ebetso ea ho phatloha e ntlafalitsoe.Haeba ho se na ntlafatso, hlahloba hore na motsoako o bolokiloe nako e telele kapa hore na o na le litšila tse ngata.
