Piv nrog rau lwm cov hlau siv rau electroplating, zinc yog qhov pheej yig tshaj, thiab corrosion kuj ntawm zinc yog zoo dua li ntawm cov hlau feem ntau. Yog li ntawd, feem ntau ntawm cov ntsia hlau dav hlau los yog cov ntsia hlau uas muaj qhov cuam tshuam rau atmospheric corrosion yog galvanized, tab sis cov ntsia hlau tsis muaj qhov zoo ib yam lossis du nto li daim hlau lossis cov pas nrig. Lub pem hauv ntej kawg ntawm lub roob xov yog thib ob, thiab xov hav yog qhov thinnest. Txhawm rau koom tes nrog cov khoom loj ntawm cov ntsia hlau, txo cov nqi thiab nce ntau lawm, txoj kev galvanizing rau hauv cov thoob feem ntau yog ua los ntawm electroplating. Txoj kev no yog ua kom cov dej ntws tam sim no los ntawm cov electrodes ntawm lub thoob khib nyiab mus rau cov xov hlau hauv lub thoob, thiab cov xov hlau nyob hauv kev sib cuag nrog cov ntsia hlau los ua hluav taws xob, thiab tib lub sij hawm lub thoob yog tig thiab cov ntsia hlau yog nplawm kom thiaj li. cov ntsia hlau yog nyob rau hauv txawm kev sib cuag nrog lub electrode. Txawm li cas los xij, nyob rau lub sijhawm no, qhov tam sim no tsis sib xws thiab nws nyuaj rau tsim ib qho kev sib txawv tam sim no, yog li lub thickness ntawm galvanized kuj yooj yim sib txawv.
Electroplating galvanizing tuaj yeem siv ob hom kua qaub electroplating tov thiab alkaline electroplating kua. Cov kua qaub electroplating feem ntau yog tsim los ntawm zinc sulfate, uas yog pheej yig thiab siv tau, electroplating ceev ceev, yooj yim los tswj, thiab nws kuj tsis tshua muaj hydrogen embrittlement dua li alkaline electroplating tov. Txawm li cas los xij, cov muaju yog me ntsis coarser, lub gloss tsis zoo, thiab lub peev xwm cuam tshuam tsis zoo. Alkaline electroplating kua yog tsim los ntawm zinc oxide. Txawm hais tias tus nqi siab, nws muaj peev xwm ua tau zoo. Tsuav nws tau raug tswj kom zoo, ib txheej glossy tuaj yeem tau txais. Yog tias kev kho chromate ntxiv lawm, cov txheej ci tuaj yeem tau txais. Thiab zoo heev corrosion kuj.
Kub-dip galvanizing kuj tseem siv rau saum npoo corrosion tiv thaiv ntawm screws, bolts thiab ceev. Kub-dip galvanized screws muaj kev tiv thaiv corrosion zoo dua li cov ntsia hlau electro-galvanized, tab sis tus nqi siab dua, thiab cov khoom siv muaj zog siab tsis haum. Kub-dip galvanizing, vim hais tias ntawm cov txheej txheej yog ib qho yooj yim los ua ib qho nyuaj thiab nkig, nws yuav tawg ntawm qhov kub thiab txias. Nyob rau hauv cov cheeb tsam uas muaj sulfides, nws cov corrosion kuj tsis zoo, thiab nyob rau hauv marine thiab tropical huab cua, ib tug loj tus naj npawb ntawm tus kheej-chromatic corrosive khoom yuav tsum tau kho nrog chromate los tiv thaiv nws.
