Dab tsi yog txoj hauv kev ua haujlwm ntawm passivation rau galvanized steel ntawv?
Chromate passivation ua ib zaj duab xis passivation. Trivalent chromium tsim lub hauv paus ruaj khov, thaum hexavalent chromium ua raws li re-passivator thaum cov zaj duab xis passivation raug khawb, tiv thaiv kev xeb ntawm cov ntawv hlau galvanized los ntawm huab cua ntub.
Yuav ua li cas kuaj qhov corrosion kuj ntawm kub -dip galvanized steel ntawv?
Ob txoj hauv kev yog cov ntsev tsuag tshuaj simulating ib puag ncig marine thiab kev ntsuas kub kub simulating huab cua ntub. Accelerated corrosion tests ntsuas qhov corrosion kuj ntawm txheej.
Dab tsi yog qhov ua rau zinc particles hauv galvanized steel ntawv?
Kev huv tsis zoo ntawm cov ntawv qub thiab cov hmoov hlau hlau siab; kub zinc da dej kub heev ua rau hauv qab slag ntab; thiab ntau cov ntsiab lus txhuas hauv zinc da dej cuam tshuam rau cov hlau solubility-tag nrho cov no tuaj yeem ua rau zinc particles.
Dab tsi yog qhov tseem ceeb ntawm kev ua tiav kub -dip galvanized steel ntawv?
Nws tuaj yeem txhim kho qhov flatness ntawm cov ntawv nyias, flatten nto zinc particles, tsim kom haum roughness, txhim kho txheej adhesion, tshem tawm yield plateaus, tiv thaiv kab nrib pleb thaum ua, thiab txhim kho kev sib sib zog nqus - kos duab.
Dab tsi yog qhov ua rau tsis tiav galvanizing hauv cov khoom galvanized? Cov plating tsis zoo tuaj yeem tshwm sim los ntawm cov kab mob xws li xim thiab xeb ntawm qhov chaw plated; tsis tsim nyog pickling los yog overlapping ntawm plated qhov chaw uas ploj lawm; tsis zoo flux concentration; ntau cov ntsiab lus txhuas hauv zinc da dej; los yog tsis txaus immersion lub sij hawm los yog qeeb loading ceev.
