Suuqa dhuumaha birta ee hadda jira, dhuumaha birta galvanized ee kulul ayaa aad caan u ah dadka dhexdooda sababtoo ah kharashkeeda wax ku ool ah, nidaamka ilaalinta daxalka ee aan dayactirka lahayn kaas oo awoodi doona inuu sii jiro tobanaan sano xitaa jawiga ugu adag. Farsamo ahaan, lakabka zinc ee tuubada galvanized ee kulul ayaa ka adkeysi badan daxalka marka loo eego birta iyo birta qaawan. Si kastaba ha ahaatee, iyada oo ay ugu wacan tahay tignoolajiyadeeda gaarka ah ee wax-soo-saarka iyo kharashyada wax soo saarka ee sarreeya, tuubada galvanized ee kulul waxay leedahay qiimo ka sarreeya tuubooyinka kale ee caadiga ah ee suuqa birta.
Galvanizing waa si fudud oo lagu dahaadhay zinc ka kor alaabada birta ah. Sida rinjiga oo kale, dahaarka galvanized wuxuu ka ilaaliyaa alaabada birta ee daxalka isagoo ka dhigaya caqabad u dhaxaysa saldhigga birta iyo deegaanka, laakiin galvanization-ku wuxuu aadayaa hal tallaabo oo weyn oo ka dheer rinjiga. Sida xirfadle soo saaraha tuubooyinka birta, waxaanu soo jeedinaynaa in rinji si habboon loo mariyo si wax ku ool ah dib loogu soo celiyo ilaalinta daxalka buuxa ee meelaha alxanka xaaladaha qaarkood. Guud ahaan rinjiyadani waxay ku jiraan gasacadaha buufinta ama weelasha ku habboon buraashka ama buufinta.
Xaaladaha intooda badan, dayactirka tuubooyinka birta galvanized ee kulul waxay ku lug leedahay noocyada ugu badan ee waxyeelada ama xumaanshaha nidaamka tuubooyinka, sida daxalka gudaha iyo dibadda, iyo sidoo kale xaaladaha ay waxyeelladu aad u ballaaran tahay. Marka laga hadlayo qaar ka mid ah tuubooyinka birta duuban ee qabow, taabashada iyo hagaajinta daaha birta galvanized ee kulul ayaa muhiim ah si loo ilaaliyo xannibaadaha isku midka ah iyo ilaalinta cathodic iyo sidoo kale hubinta cimri dhererka. Inkasta oo daahan galvanized kulul rusheeyey uu yahay mid aad u adkaysta waxyeello, banaanayn yar yar ama cilladaha daahan ayaa dhici kara inta lagu guda jiro geeddi-socodka galvanizing ama ay sabab u tahay maaraynta khaldan ee birta ka dib galvanizing. Taabashada iyo hagaajinta birta galvanized waa sahlan tahay hadday galvanized cusub tahay ama ha ahaato mid sanado badan shaqaynaysa. Dhaqanku waa isku mid, laakiin waxaa jira xannibaadyo badan oo lagu hagaajinayo la oggol yahay ee badeecad cusub marka loo eego mid adeegi jiray. Xayiraadda ugu weyn ee qeexitaanka hagaajinta walxaha cusub ee galvanized waa cabbirka aagga kaas oo lagu qeexay qeexida galvanizing alaabta. Iyo mabda' kale oo tilmaamaya taabashada iyo hagaajinta waa dhumucda dahaarka ee goobta dayactirka.
Galvanizing Hot Dip Galvanizing guud ahaan waxaa lagu dhammeeyaa laba hab, kuwaas oo labaduba ku dhex geliso ama ku dabool birta qubeyska zinc dareeraha ah ka dib habab kala duwan. Dahaarkan ilaalinta ayaa ah isku-dhafka zinc iyo birta, kaas oo socon doona sanado badan. Si kastaba ha noqotee, haddii badeecadaadu u baahan tahay jarid, alxan ama si kale wax-abuuris, waxaa la soo jeediyay in la sameeyo marka hore, ka dibna galvanized.
