Rinjiga lakabka galvanized, xoogga isku xirnaanta ee ka dhexeeya midba midka kale wuxuu xiriir weyn la leeyahay heerkulka dubista ee rinjiga, iyo rinjiga alkyd waa la dahaadhay ka dib galvanized, iyo adhesion ma aha dhibaato.Ka dib markii galvanized si loo sameeyo rinjiga amino, ku dheggan rinji aad uma fiicna.Samee laba hoose oo laba dusha sare ah, dhejisku waa wanaagsan yahay, haddii labada hoose ee labada hoose ay isku beddelaan laba hoose oo saddex ah, taas oo ah, rinji badan, marar badan oo la dubay, mar labaad tijaabinta adhesion waa mid aad u xun, xun oo ku filan in la jeexjeexo rinjiga lakabka galvanized. .
Ma samayn tijaabada adhesion ee buufinta budada ama buufinta fluorocarbon ee baakadaha siliga galvanized, laakiin waxaa jira laba dhibcood oo tixraac ah: mid, jawiga wareega ama wareegga hawada, qallafsanaanta aan birta ahayn waxay daahan kartaa daahan zinc;Marka labaad, zinc ka sarreeya 230 darajo (c) ayaa jebin doona birta saldhigga ah.Ka dib buufinta budada iyo buufinta fluorocarbon, waxaa lagama maarmaan ah in lagu dubo heerkul sare iyo jawi xiran, taasoo keenaysa daxalka degdega ah ee zinc, taasoo keentay filimka daxalka dabacsan taasoo keentay hoos u dhaca adhesion ee daahan, iyo xitaa taasoo keentay in xaalad jajaban ee silig birta.
Sababtoo ah xadhigga galvanized ee la isku dhejiyey waxaa lagu daboolay xiisad hore, sidaas darteed waxay leedahay sifooyinka ugu fiican ee qiimaha nasashada ee hooseeya, luminta walbahaarka yar yar, xasilloonida wanaagsan ka dib marka la soo dhejiyo, ma fududa in la gooyo, jab la'aan, dabacsanaan xooggan, khadadka birta caadiga ah iyo rebar waa adag tahay. in la isku beego.Isticmaalka habka dhamaystirka sare ee galvanized, sidaas darteed, isticmaalka kulul-muquufin dhismaha silig birta galvanized, ma aha oo kaliya waxqabadka anti-daxalka wanaagsan, iyo deeqsi qurux badan.Alaabtu waxay leedahay sifooyinka dusha siman, saxnaanta cabbirka sare, labbiska wanaagsan ee lakabka zinc iyo dhejinta adag.
