Galvanizing waxaa loola jeedaa tignoolajiyada daaweynta dusha sare ee lagu dhejiyo lakabka zinc ee dusha sare ee birta, daawaha ama walxaha kale si loogu ciyaaro saameynta ka hortagga bilicda iyo miridhku. Habka ugu muhiimsan ee loo isticmaalo waa galvanization-kuleyl.
Zinc si fudud bay ugu milmi kartaa acids iyo alkali, sidaas awgeed waxa loo yaqaannaa birta amphotropic. Zinc aad ayay wax ugu badashaa hawada qalalan hydrogen sulfide iyo jawiga badda, caabbinta daxalka zinc waa liidata, gaar ahaan heerkulka sare iyo huurka sare ee ka kooban jawiga acid organic, daahan zinc waa fududahay in la daxaleeyo. Awoodda electrode caadiga ah ee zinc waa-0.76V, waayo matrix birta ah, daahan zinc waxaa iska leh daahan anodic ah, waxaa inta badan loo isticmaalaa si looga hortago daxalka ee birta, ay waxqabadka ilaalinta iyo dhumucdiisuna daahan waa mid aad u dhow. daawaynta passivation, wasakhaynta ama dahaarka leh wakiilka iftiinka, waxay si weyn u wanaajin kartaa ilaalinteeda iyo qurxinta.
galvanizing qabow
Galvanizing Cold, oo sidoo kale loo yaqaan electrogalvanizing, waa isticmaalka qalabka electrolytic ka dib saliidda, pickling, zinc milixda galay xalka, oo ku xidhi electrode taban ee qalabka electrolytic, in ka soo horjeeda saxan zinc ah, ku xiran electrode togan ee electrolytic ah. awoodda qalabka, iyadoo la isticmaalayo hadda ka togan ilaa taban waxay dhigi doontaa lakabka zinc on tuubada, tuubada dahaadhays qabow ayaa marka hore ka baaraandegaya ka dib galvanizing.
Makaanikada galvanized
Durbaanka wareegta ah ee lagu rakibay dahaadhida, kubbadda dhalada, budada zinc, biyaha iyo dhiirigeliyaha, kubbadda dhalada sida saamaynta dhexdhexaadka ah waxay ku wareegtaa durbaanka, xoqidda iyo dubbaha dusha sare ee dahaadhka waxay soo saaraan tamar jireed farsamo.Marka la eego ficilka dhiirrigeliyaha kiimikada, budada zinc ee dahaarka leh "alxanka qabow" ee dusha sare ee daahan, samaynta dahaar siman, labis ah oo faahfaahsan oo leh dhumuc gaar ah.
Kulul galvanized
Habka ugu muhiimsan ee galvanizing dusha saxan bir ah waa galvanizing kulul.
Galvanizing Hot waxaa laga soo saaray habab hore oo waa boqol iyo toddobaatan sano jir tan iyo markii loo adeegsaday warshadaha 1836. Si kastaba ha ahaatee, warshadaha galvanized kulul-muquufin ayaa la horumariyo on baaxad weyn oo ay la socdaan horumarinta degdegga ah ee birta xariijimaha qabow-duuban. soddonkii sano ee la soo dhaafay.
Habka wax soo saarka ee saxan galvanized kulul inta badan waxaa ka mid ah: saxan asalka ah pre-daayey maquufin kulul post-daawaynta dhammeeyey kormeerka alaabta, etc.Sida ay caado, sida ay habka daaweynta dahabi ah oo kala duwan, geeddi-socodka galvanizing maquufin kulul waxaa loo qaybiyaa line ka baxsan. iyo xajinta xariiqda gudaha.
