Anti-corrosion kev kho mob ntawmhlau mesh laj kabnets feem ntau muab faib ua ob hom: ib qho yog dipping thiab lwm yam yog kub-dip galvanizing. Kev kho dipping ntawm lub mesh ntawm lub laj kab yog txheej txheem txheej yas. Kev kho dipping yog muab faib ua kub dipping thiab txias dipping raws li seb cua sov puas tsim nyog. Raws li cov ntaub ntawv qub ntawm dipping, nws tuaj yeem muab faib ua kua dipping thiab hmoov. Cov kev sib raug zoo yog muab faib ua kua dipping ua thiab hmoov dipping ua. Cov khoom siv txias dipping feem ntau yog hom kev cob qhia. Kub dipping yog yuav tsum tau rhuab txhua xyoo puag ncig. Feem ntau cov chaw ua haujlwm me me siv cov dej txias thiab dipping. Nws tuaj yeem muab faib ua ob peb xim: tsaus ntsuab nyom ntsuab, xim xiav thiab lwm yam.
Kev siv cov kub-dip galvanizing rau lub mesh ntawm lub laj kab yog tsim los ntawm lub sij hawm ntev kub-dip qhov rooj txoj kev. Nws muaj keeb kwm ntawm 140 xyoo txij li thaum Fabkis tau siv kub-dip galvanizing rau kev lag luam hauv xyoo 1836. Txawm li cas los xij, kev lag luam kub-dip galvanizing tau ua tiav kev loj hlob nrog kev loj hlob sai ntawm cov khoom txias-dip galvanizing hauv 30 xyoo dhau los.
Cov txheej txheem ntawm cov ntawv kub-dip galvanized feem ntau suav nrog: thawj board npaj → pre-plating kev kho mob → kub-dip plating → tom qab-plating kev kho mob → tiav cov khoom soj ntsuam, thiab lwm yam. Qhov kom zoo dua ntawm kub-dip galvanizing lub laj kab yog tias nws muaj lub sij hawm ntev los tiv thaiv corrosion, thiab ua kom haum rau ib puag ncig ib txwm yog ib qho kev tiv thaiv zoo heev. Kub-dip galvanizing muaj lub neej ntev los tiv thaiv kev ua khawv koob, tab sis lub neej tiv thaiv kev ua khawv koob txawv hauv qhov chaw sib txawv:
Lub hauv paus ntsiab lus ntawm kub-dip galvanizing: ntxuav cov hlau qhov chaw, tom qab ntawd kho cov kuab tshuaj, raus hauv cov kua zinc tom qab ziab, cov hlau reacts nrog molten zinc los ua ib txheej zinc alloyed, txheej txheem yog: degreasing-dej-dej-pickling- Pab plating-qhuav-kub dip galvanizing-sib cais-txias passivation. Lub thickness ntawm cov kub-dip galvanized alloy txheej feem ntau yog nyob ntawm cov ntsiab lus ntawm silicon thiab lwm yam tshuaj lom neeg ntawm cov hlau, qhov chaw hla ntu ntawm cov hlau, qhov roughness ntawm cov hlau nto, qhov kub ntawm lub lauj kaub zinc, lub sij hawm galvanizing, txias ceev, thiab txias dov deformation.
