Ntsiab cai ntawm galvanizing
Hauv lub plating lub tank uas muaj cov kua roj galvanizing, qhov raug ntxuav thiab tshwj xeeb pretreated qhov yuav plated yog siv raws li cathode, thiab anode yog ua los ntawm cov hlau plated, thiab ob tus ncej txuas feem cuam tshuam nrog qhov zoo thiab tsis zoo electrodes ntawm DC zog. mov. Cov kua pleev zinc plating yog tsim los ntawm cov tshuaj tov aqueous uas muaj cov hlau-plated tebchaw, cov kua ntsev conductive, buffers, pH hloov kho, ntxiv rau, thiab cov zoo li. Tom qab ua kom muaj zog, cov hlau ions hauv cov zinc plating da dej txav mus rau cathode nyob rau hauv kev ua ntawm qhov sib txawv muaj peev xwm los ua daim plating txheej. Cov anode hlau tsim cov hlau ions rau hauv cov tshuaj zinc plating kom muaj kev saib xyuas ntawm cov hlau ions yuav tsum tau plated. Qee qhov xwm txheej, xws li chromium plating, insoluble anode ua los ntawm cov hlau lead thiab lead-antimony alloy yog siv, uas tsuas yog ua haujlwm rau xa cov hluav taws xob thiab kev coj ua tam sim no. Cov concentration ntawm chromium ions nyob rau hauv cov xaim hluav taws xob xav tau los ntawm kev saib xyuas los ntawm niaj zaus ntxiv cov tshuaj chromium rau cov tshuaj plating. Thaum galvanizing, qhov zoo ntawm cov khoom siv anode, muaj pes tsawg leeg galvanizing daws, kub, qhov ceev tam sim no, lub zog energization, nplawm siv zog, precipitated impurities, hwj chim waveform, thiab lwm yam yuav cuam tshuam rau qhov zoo ntawm cov txheej thiab xav tau tswj hauv ib raws sijhawm.
