Thaum xaiv ntawm cov zinc plating dub thiab blackening rau cov ntsia hlau nto, nws yog ib qho tseem ceeb uas yuav tsum xav txog ntau yam tseem ceeb:
Txheej Thickness: Lubzinc dub plating ntsia hlaufeem ntau muaj ib txheej tuab dua piv rau qhov ua kom dub. Qhov no yog vim muaj kev sib xyaw ua ke ntawm sodium nitrate ntawm kwv yees li 160 ° C thiab cov pa roj carbon, ua rau muaj cov hlau dub oxide (Fe3O4) thaum lub sijhawm ua kom dub, uas ua rau cov txheej nyias nyias.
Cov tshuaj tiv thaiv hauv Acid: Kev raus dejcov ntsia hlauhauv cov kua qaub tuaj yeem muab cov lus qhia txog lawv cov kev kho saum npoo. Yog tias cov ntsia hlau dub pom ib txheej dawb tom qab cov txheej dub raug tshem tawm hauv cov kua qaub thiab txuas ntxiv cuam tshuam nrog cov kua qaub, nws qhia tias passivated dub zinc plating. Txwv tsis pub, nws feem ntau yog dub.
Kev Kuaj Khawm: Lwm txoj hauv kev los paub qhov txawv ntawm cov kev kho no yog siv kev kuaj khawb yooj yim nrog ib daim ntawv dawb. Kev khawb ib qho chaw dub yuav ua rau xim ploj mus, vim tias kev dub cuam tshuam nrog kev tshuaj lom neeg uas hloov pauv qhov chaw. Ntawm qhov tod tes, cov ntsia hlau nrog cov zinc plating dub yuav khaws lawv cov txheej thaum cov khoom zinc tau sib txuas rau qhov chaw los ntawm electroplating.
Peb cov ntsia hlau muaj ntau yam khoom siv xws li cov hlau carbon, cov hlau tsis xeb, tooj dag, cov hlau sib xyaw, thiab ntau ntxiv. Lawv tuaj yeem hloov kho kom haum rau koj cov kev xav tau tshwj xeeb. Nrog rau cov zinc dub uas tiv taus corrosion, peb cov ntsia hlau muab kev tiv thaiv zoo heev rau kev puas tsuaj ib puag ncig thiab ua kom pom qhov tiav zoo. Xwb,cov ntsia hlau dubmuab kev tiv thaiv oxidation zoo dua nrog rau qhov pom ntawm qhov chaw qis-gloss, ua rau lawv haum rau cov ntawv thov uas xav tau cov chaw tsis muaj kev cuam tshuam.
Hauv kev xaus, kev nkag siab txog qhov sib txawv ntawm cov zinc dub plating thiab blackening yog qhov tseem ceeb rau kev xaiv hom kev xaiv zookev cai ntsia hlauuas zoo tshaj plaws rau koj daim ntawv thov xav tau. Xaiv los ntawm peb cov kab ntawmcov ntsia hlau zoouas ua tau raws li cov qauv kev lag luam ntawm ntau yam lag luam.
