1. Vim tias muaj roj nyob rau sab nrauv phab ntsa ntawm lub hauv paus raj, cov roj nyob rau ntawm phab ntsa ntawm cov yeeb nkab steel yuav ua rau kom pom kev nro, thiab cov txheej txheem pickling ua ntej galvanized tsis tuaj yeem tshem tawm cov roj saum npoo. Lub raj basal yog xeb, thiab qee zaum tus neeg sawv cev plating tsis txuas, thiab kev tiv thaiv ntsev pwm tsim. Nyob rau hauv qhov kub-kub melting zinc tank, cov yeeb nkab steel yog oxidized sai, yog li zinc kua yuav tsis tsim cov tshuaj lom neeg lossis lub cev cuam tshuam nrog lub substrate. Tom qab cov yeeb nkab steel tau sib cais los ntawm zinc kua pas dej, nyob rau hauv qhov cuam tshuam ntawm lub ntiajteb txawj nqus, cov zinc kua yuav ntws thiab tsis sib xws, yog li tseem yuav muaj cov hmoov tshauv dub hauv cov zinc txheej nyias.
2. Sab nrauv ntawm lub hauv paus hlau alloy tau raug corroded hnyav heev. Cov yeeb nkab steel tsis huv, thiab hlau oxide tseem nyob. Txawm hais tias qhov kev pabcuam plating tuaj yeem ua raws li nws, thaum lub hauv paus raj yog immersed nyob rau hauv melted zinc tov, zinc kua tsis tuaj yeem raug ncaj qha rau cov hlau thiab tsis muaj cov tshuaj tiv thaiv. Tom qab cov yeeb nkab steel yog sib cais los ntawm cov zinc kua pas dej ua ke, sab sab raug kuj huv si, yog li qhov saum npoo ntawm galvanized tsev xog paj raj yuav raug eroded me ntsis.
3. Lub phab ntsa ntawm lub basal raj muaj cov roj thicker thiab nyuaj rau tshem tawm cov stains, yog li nws yuav inevitably xau plating, thiab nws yuav tsis yooj yim heev rau txheej txheem, vim hais tias cov yeeb nkab steel yuav tsum tau ntxuav txij thaum pib mus txog rau thaum xaus. Lub raj phab ntsa ntawm lub hauv paus raj muaj qhov zoo ib yam li qhov loj ntawm mung taum. Thaum ci, zinc kua ntawm cov yeeb nkab steel yeeb nkab yog txuas nrog rau saum npoo ntawm cov yeeb nkab steel. Zoo li xeb hlau kav. Tag nrho cov xau yog tib yam, tab sis qhov dej xau nyob rau hauv qhov xwm txheej no yog qhov me me thiab me me, thiab cov npoo yog qhov tiaj tus.
4. Muaj cov caws pliav ntawm phab ntsa ntawm lub raj basal thiab cov tsos ntxhib. Obviously, stains yuav nkag mus rau hauv kos. Nws yog ib qho nyuaj rau tshem tawm xws li av ua ntej galvanizing lub pickling thiab alkali ntxuav cov kauj ruam. Qhov tsis xws luag yog nthuav tawm nrog ib daim ntawv ntev thiab nthuav dav. Qhov kev xau no tsawg heev.
5. Thaum lub sij hawm txheej txheem galvanized, qhov kub thiab txias tsis ua raws li qhov yuav tsum tau ua, thiab galvanized tsev cog khoom tube yog qhov ua rau to.
