Dab tsi yog qhov corrosion kuj ntawm SGCC coils?
Teb: SGCC coils muaj corrosion kuj zoo heev. Lawv cov kub-dip galvanized txheej ua rau lub cev tsis muaj zog, tiv thaiv corrosive media xws li dej thiab oxygen los ntawm kev sib cuag nrog cov hlau. Thaum cov zinc txheej puas lawm, zinc nyiam corrodes los ntawm electrochemical tshuaj tiv thaiv, tiv thaiv cov hlau. Cov xeb- pov thawj feem ntau kav ntev li 30-50 xyoo.
Vim li cas SGCC coils muaj qhov zoo corrosion kuj?
Teb: Ua ntej, cov kub-dip galvanized txheej muab lub cev muaj zog, tiv thaiv corrosive media los ntawm kev sib cuag nrog cov substrate. Qhov thib ob, zinc yog tshuaj lom neeg ntau dua li hlau. Thaum cov zinc txheej puas lawm, zinc nyiam oxidizes raws li anode, tiv thaiv cov hlau substrate, uas ua raws li cathode. Qhov kev tiv thaiv electrochemical no tseem hu ua sacrificial anode tiv thaiv.
Cov kev kho saum npoo dab tsi muaj rau SGCC coils?
Teb: Cov kev kho saum npoo feem ntau suav nrog passivation (C), phosphating (P), oiling (O), thiab tiv thaiv - ntiv tes txheej (N).
Dab tsi ua haujlwm yog tsim nyog rau SGCC coils?
Teb: SGCC coils yog tsim rau kev ua haujlwm xws li vuam, stamping, dabtsi yog khoov, thiab txiav. Cov txheej txheem txias dov ua rau lub ntsej muag du thiab cov tuab tuab, muab kev ua haujlwm zoo heev.
Dab tsi yuav tsum tau ceev faj thaum khoov SGCC coils?
Teb: Thaum khoov, ceev faj kom tsis txhob nqaim ntau dhau ntawm qhov khoov vojvoog kom tsis txhob tawg lossis poob ntawm zinc txheej. Cov khoom siv khoov tsim nyog thiab cov pwm yuav tsum tau xaiv raws li qhov tuab thiab lub zog ntawm daim ntawv.
