Galvanized steel kav muab faib ua ob pawg -kub -dip galvanized steel kav thiab txias galvanized steel kav. Cold galvanized steel kav yog electroplating steel kav. Cov ntsiab lus ntawm galvanizing yog tsawg heev. Nws tsuas yog 10g rau 20g ib square meter. Nws cov corrosion kuj tsis zoo li kub galvanized steel kav. Tsis tas li ntawd, qhov sib txawv ntawm ob yog dab tsi?
Qhov txawv ntawm kub-dip galvanized steel yeeb nkab thiab txias galvanized steel yeeb nkab
Ua ntej: Ob qhov sib txawv heev hauv txoj kev ua haujlwm. Cov zinc siv nyob rau hauv kub-dip galvanized yog tau nyob rau hauv qhov kub ntawm 450 ° C mus rau 480 ° C; zinc nyob rau hauv txias galvanized steel kav yog tau los ntawm electroplating txheej txheem ntawm chav tsev kub.
Thib ob: Lub thickness ntawm cov yeeb nkab txias galvanized thiab kub-dip galvanized yeeb nkab yog txawv heev nyob rau hauv lub thickness ntawm galvanized txheej. Lub thickness ntawm zinc nyob rau hauv kub galvanized steel yeeb nkab yog ntau dua li cov thickness ntawm zinc nyob rau hauv txias galvanized steel yeeb nkab.
Peb: Qhov saum npoo ntawm ob qhov sib txawv. Qhov saum npoo ntawm qhov txias-dip galvanized steel yeeb nkab yog ntxhib ntau dua li kub-dip galvanized steel kav.
Plaub: Cov kav dej txias galvanized thiab cov kav dej kub-dip galvanized kuj sib txawv ntawm tus nqi. Txhawm rau kom ntseeg tau qhov zoo, cov kav dej kub-dip galvanized steel feem ntau tsis siv txoj kev galvanized xws li electroplating; thiab cov lag luam me me nrog cov cuab yeej qub qub yuav tau txais electroprilizer. Yog li ntawd nws yog qis dua kub-dip galvanized steel kav.
Thib tsib: Kub-dip galvanized steel kav yog tag nrho cov zinc nrog steel kav, thaum lub txias galvanized steel yeeb nkab tsuas yog galvanize steel yeeb nkab sab.
Thib rau: Qhov adhesion ntawm ob qho tib si kuj txawv heev. Lub adhesion ntawm txias galvanized steel kav yog qhov phem tshaj qhov adhesion ntawm kub-dip galvanized steel kav, vim hais tias cov yeeb nkab steel matrix ntawm txias galvanized steel yeeb nkab thiab zinc txheej yog ywj siab, zinc txheej yog nyias nyias, thiab nws tsuas yog txuas nrog. mus rau saum npoo ntawm cov yeeb nkab steel matrix lub cev lub cev. Nws yog ib qho yooj yim kom poob tawm.
Cov txheej txheem ntawm txias galvanized steel kav yog electroplating. Sab hauv phab ntsa ntawm cov yeeb nkab steel tsis yog galvanized, thiab zinc muab tso rau ntawm phab ntsa sab nrauv ntawm cov yeeb nkab steel. Lub xeev tau ua cov kev cai tseem ceeb uas qhov kev tiv thaiv corrosion ntawm cov kav dej txias galvanized yog qhov tsis zoo, cov zinc txheej kuj yooj yim poob, thiab muaj kev nyab xeeb kev nyab xeeb. Yog li ntawd, nws tsis tuaj yeem siv los ua cov kav dej thiab cov kav dej.
Hauv cov ntsiab lus, qhov sib txawv ntawm ob yog qhov tuab ntawm zinc, sib txawv smoothness, txawv tus nqi, txawv tus nqi, txawv corrosion kuj, thiab sib txawv adhesion.
