Hot dipwaya wachitsulo chagalasiamapangidwa ndi waya ndodo pambuyo kujambula, kutentha, ndiyeno kujambula, Z ndi njira yotentha yoviika pamwamba yokutidwa ndi zinki.Kuchuluka kwa zinki nthawi zambiri kumayendetsedwa mumtundu wa 30g/m^2-290g/m^2 malinga ndi zofunikira za malo ogwiritsira ntchito.Chifukwa mankhwala opangidwa ndi otentha dip galvanizing ndondomeko ndi moyo wautali anticorrosive ndi malo ambiri ntchito, otentha dip galvanizing chitsulo waya chimagwiritsidwa ntchito makampani olemera, makampani kuwala, ulimi ndi madera ena mu mawonekedwe a ukonde, chingwe, waya ndi zina zotero.
Kutentha kwa dip galvanizing kumatchedwanso kuti dip dip zinc ndi dip yotenthagalvanizing: ndi njira yothandiza ya anticorrosion yachitsulo, yomwe imagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana opangira zitsulo.Ndiko kumiza zitsulo pambuyo pochotsa dzimbiri mu njira ya zinki yosungunuka pafupifupi 500 ℃, kotero kuti pamwamba pa ziwalo zazitsulo zimamangiriridwa ndi nthaka wosanjikiza, kuti azisewera cholinga cha anticorrosion.Hot dip galvanizing ndondomeko: kumaliza mankhwala pickling - kuchapa - kuwonjezera plating njira - kuyanika - plating plating - kuzirala - mankhwala - kuyeretsa - kupukuta - kutentha divi galvanizing kwatha.
Waya wotentha wotentha umatchedwanso zinc dip ndi dip otenthawaya wamalata, amapangidwa ndi waya ndodo pojambula, kutentha, ndiyeno kujambula, potsirizira pake ndi njira yotentha yopaka pamwamba yomwe imakutidwa ndi zinki ndi kupanga waya.Kuchuluka kwa Zinc kumayendetsedwa ndi 30g/m^2-290g/m^2 sikelo.Amagwiritsidwa ntchito makamaka m'mafakitale osiyanasiyana a zida zachitsulo.Ndiko kumiza zigawo zachitsulo pambuyo pochotsa dzimbiri mu njira yosungunuka ya zinki pafupifupi 500 ℃, kotero kuti pamwamba pa ziwalo zazitsulo zimamangiriridwa ndi nthaka wosanjikiza, ndiyeno kusewera cholinga cha anticorrosion.
Passivation, kutentha kusungunuka, kutseka ndi dehydrogenation wa kutentha-kuviikawaya wamalatapambuyo plating pofuna kupititsa patsogolo chitetezo, kukongoletsa ndi zina zapadera.Chromic acid mchere passivation kapena kusintha kwina amakonzedwa kawirikawiri pambuyo galvanizing, filimu yosinthika yomwe imapanga mtundu wofananira ndi imodzi mwa njira zazikulu zogwirira ntchito zomwe zimatsimikizira ubwino pambuyo pa plating.
