1. Corrosion mechanism sib txawv
Carbon steel (Q235, Q355, SS400 thiab lwm yam)Xeb txheej yog xoob, ntxeem tau, thiab yooj yim rau poob.Moisture thiab oxygen kom nkag mus rau sab hauv, yog li corrosionaccelerates tsis tu ncuamus txog rau perforation.
Q460NH huab cua steelMuaj cov ntsiab lus alloy (Cu, Cr, Ni, P) uas tsim antom, nruj, nplaum patinanyob rau saum npoo.Qhov txheej no thaiv cov khoom nruab nrab ntawm corrosion thiab ua rau tus nqi corrosion poob sharply mus rau ib qho qis heev.
2. Kev sib piv ntawm corrosion
Nyob rau hauv tib yam unpainted sab nraum zoov cua:
Q460NH corrosion tus nqi:tsuas yog li ntawm 1/5 txog 1/8 ntawm carbon steel
Carbon steel rusts los ntawm ob peb xyoos; Q460NH tuaj yeem siv ruaj khov rauxyoo lawm
3. Kev ua tau zoo hauv qhov chaw sib txawv
Nyob deb nroog / nroog / industrial cuaQ460NH: zoo heev, ruaj khov patina, yuav luag tsis sib sib zog nqus corrosionCarbon steel: hnyav xeb, pom tseeb thickness poob
High humidity, cua tsis zooQ460NH: corrosion qeeb qeeb tab sis tseem zoo dua li carbon steelCarbon steel: ceev heev corrosion
Ntug ntsev- thaj chaw tshuaj tsuagOb qho tib si dhau los, tab sis Q460NH tseem ua tau zoopom tseeb zoo duatshaj carbon steel
Dej immersion / fausOb leeg poob kev tiv thaiv zoo, tab sis Q460NH tseem muaj qhov ua tau zoo dua me ntsis
4. Qhov txawv ntawm lub xeev
Cov pa roj carbon steel: xoob daj- liab xeb, dej ntws loj, yooj yim rau cov ntaub ntawv nyob ib puag ncig
Q460NH: maj mam tsim cov xim av xim av ruaj khov patina, me ntsis kom tsis muaj dej ntws
