Yuav ua li cas los tuav lub caij nplooj ntoos hlav ntau dhau thaum khoov SPCC nplooj ntawv?
A: Optimize qhov khoov tuag tsim los ntawm kev ua kom lub vojvoog tuag; tsim nyog nce lub siab dabtsi yog khoov thiab ncua lub sijhawm tuav; ua ntej- kho cov ntaub ntawv kom tshem tawm cov kev ntxhov siab sab hauv.
Vim li cas SPCC cov ntawv tuaj yeem xeb?
A: Raws li qis-carbon txias- dov steel, nws tsis muaj cov yeeb yaj kiab tiv thaiv ntuj, ntom ntom ntawm nws qhov chaw. Nyob rau hauv ib puag ncig ntub los yog corrosive, nws nkag oxidizes thiab ua xeb.
Yuav ua li cas los txhim kho corrosion kuj ntawm SPCC ntawv?
A: Electro-galvanizing, kub-dip galvanizing, xim txheej, lossis phosphating tuaj yeem siv tau. Hauv cov xwm txheej tshwj xeeb, chromate passivation tuaj yeem siv los ua Cr₂O₃ zaj duab xis tiv thaiv. Alloyed kub-dip galvanizing tuaj yeem sib npaug corrosion kuj thiab weldability.
Qhov kev tiv thaiv corrosion ntawm electro-galvanized SPCC cov ntawv zoo li cas?
A: Nrog rau electro-galvanized txheej thickness ntawm 3-20μm thiab zinc txheej thickness ntawm 30-90g / m², nws muaj peev xwm tiv taus nruab nrab ntsev tsuag corrosion rau ntau tshaj 72 teev.
Yuav ua li cas weldability ntawm SPCC daim hlau?
Teb: Zoo heev weldability. Cov ntsiab lus carbon tsawg ua rau muaj cua sov- cuam tshuam thaj tsam hardness Tsawg dua los yog sib npaug rau 180HV, carbon sib npaug tsis tshaj 0.28%, thiab weld lub zog coefficient ntawm ntau dua 0.9.
