Qhov tseem ceeb ntawm kub-dip galvanizing ntawm Vuam Galvanized yeeb nkab nyob rau hauv hlau tiv thaiv corrosion

Qhov tseem ceeb ntawm kub-dip galvanizing ntawm Vuam galvanized yeeb nkab nyob rau hauv qhov tseeb hais tias tom qab ib txheej ntawm galvanized txheej npog lub nto ntawm hlau, corrosion kuj zoo heev, uas yuav txuag tau cov ntaub ntawv thiab kev pab. Vuam Galvanized yeeb nkab muaj kev lag luam zoo thiab ib puag ncig zoo.

Cov nyhuv tiv thaiv ntawm galvanized txheej ntawm Vuam Galvanized Yeeb Nkab rau ntawm cov hlau feem ntau suav nrog cov xwm txheej hauv qab no:

① Thaum qhov chaw ntawm Vuam Galvanized Yeeb Nkab galvanized steel qhov chaw tsis zoo, tsuas yog zinc corrosion tshwm sim. Vim muaj kev tiv thaiv zoo ntawm cov khoom siv zinc corrosion ntawm zinc, tus nqi corrosion yog qeeb heev thiab cov kev pab cuam lub neej yog 15-30 npaug ntawm cov hlau tsis muaj galvanized.

② Qhov xwm txheej feem ntau yog thaum siv Welding Galvanized Yeeb Nkab galvanized steel qhov chaw, qhov chaw yog khawb lossis cov txheej hauv zos puas vim lwm yam laj thawj. Cov hlau yog raug rau ib puag ncig los ntawm qhov txhab. Yog tias cov txheej txheem yog cov khoom siv tsis yog xim hlau, cov khoom siv hlau nplaum yuav raug corroded sai. Txawm li cas los xij, kev tiv thaiv kev tiv thaiv kev ua haujlwm tshwj xeeb rau Vuam Galvanized Yeeb Nkab galvanized steel qhov chaw slows tus nqi corrosion. Qhov no yog vim hais tias zinc nyob rau hauv lub txheej thiab cov hlau nyob rau hauv cov hlau ua lub hauv paus roj teeb nyob rau hauv ib qho chaw ntub dej. Vim cov txheej txheem electrode muaj peev xwm ntawm zinc tsuas yog -1.05V, uas yog qis dua hlau ntawm -0.036V, zinc yog oxidized li anode, thaum hlau tiv thaiv raws li cathode. Vim yog cov tshuaj tiv thaiv qeeb thiab qeeb ntawm cov khoom tsim tawm tom qab Zinc Corrosion, tag nrho cov corrosion corrosion yog kev txhim kho heev. Txoj kev tiv thaiv corrosion no hu ua sacrificial anti-corrosion.

③Feem ntau, qhov corrosion ntawm Vuam Galvanized Yeeb Nkab galvanized steel qhov chaw tsis yog tshwm sim los ntawm cov txheej txheem corrosion ntawm cov txheej txheej galvanized, tab sis los ntawm thawj corrosion ntawm cov txheej nyob rau hauv cov cheeb tsam uas muaj kev sib raug zoo ntawm cov txheej thiab cov hlau substrate yog tsis zoo, uas ua rau lub corrosion ntawm welding galvanized yeeb nkab. hnyav localized corrosion thiab poob ntawm usability. Los ntawm qhov kev pom no, adhesion ntawm galvanized txheej ntawm Vuam Galvanized Yeeb Nkab, tshwj xeeb tshaj yog tag nrho cov adhesion, yog qhov tseem ceeb tshaj qhov tuab ntawm txheej galvanized. Yog hais tias lub zos adhesion ntawm galvanized txheej tsis zoo, txawm tias cov txheej galvanized yog tuab, nws yuav pib xeb los ntawm cov adhesion tsis zoo. Qhov no zoo ib yam li "txoj cai thoob", uas yog ib qho teeb meem uas cov kws tshaj lij kev tsim khoom kub-dip galvanizing yuav tsum nkag siab.
