Silig galvanizedIsticmaalka wakhti wakhti ah, dusha sare ee lakabka galvanized ayaa dili doona, hoos u dhacaya, sidaas darteed waxay saameyneysaa quruxda siliga galvanized, kaliya si ay u oggolaato dusha sare ee lakabka galvanized oo dhan laga saaro, ka dib markii la nadiifiyo, dib-u-daboosho, sidaas darteed si loo hubiyo in siligga galvanized ka sii isticmaalka muddada dheer.
Ugu horreyntii, baahida loo qabo sodium hydroxide 200 ~ 300g / L sodium nitrite 100 ~ 200g / L biyo si aad ugu darto 1L si aad uga saarto qaybaha baahida badan iyo fiilada birta iyo wixii la mid ah.Heerkulka daawaynta waa 100 ℃, wakhtiguna waa ilaa nadiifinta.
Ilaalinta dahaarka zinc ee matrixka birta waxay leedahay laba mabda'a: dhinaca kale, inkasta oo zinc uu ka firfircoon yahay oo si sahlan u oksijiinta birta, laakiin filimkeeda oksaydhku maaha mid dabacsan oo cufan sida birta oxide.Lakabka oksaydhka cufan ee ka sameysan dusha sare wuxuu joojiyaa oksaydhka dheeraadka ah ee zinc gudaha gudaha.Gaar ahaan ka dib bakhtiintagalvanizedlakabka, dusha sare ee lakabka oksaydhku waa badan yahay oo cufan, lafteedu waxay leedahay ka hortag sare oo oksaydh ah.
Dhanka kale, marka dusha sare eegalvanizedlakabka ayaa waxyeeloobay, oo soo bandhigaya matrixka gudaha ee birta, sababtoo ah zinc waa ka firfircoon yahay birta, waqtigan, zinc wuxuu leeyahay doorka uu ku leeyahay allabari zinc anode, zinc wuxuu noqon doonaa oxidized ka hor birta, si loo ilaaliyo lakabka birta aan waxyeello u geysan.
