1. Dab tsi yog qhov tseem ceeb tshaj plaws corrosive media uas Monel alloys tiv taus?
Hydrofluoric acid (HF): Monel alloys qhia tau zoo heev tiv thaiv hydrofluoric acid thoob plaws ntau qhov ntau thiab kub, txawm tias muaj impurities xws li fluorides. Qhov no yog ib qho ntawm lawv qhov tshwj xeeb tshaj plaws corrosion-cov yam ntxwv tiv taus.
Seawater thiab marine ib puag ncig: Lawv muaj zog tiv taus pitting, crevice corrosion thiab kev ntxhov siab corrosion tawg hauv dej hiav txwv, thiab tuaj yeem ua haujlwm ruaj khov rau lub sijhawm ntev hauv marine atmospheric, txaws cheeb tsam thiab tag nrho immersion tej yam kev mob.
Alkaline daws: Monel alloys tiv taus corrosion los ntawm feem ntau alkaline media (xws li sodium hydroxide, potassium hydroxide) ntawm ntau qhov ntau thiab kub, tsis muaj kev puas tsuaj rau corrosion.
Tsis yog -oxidizing acids: Nyob rau hauv uas tsis yog - oxidizing acids (xws li dilute sulfuric acid, hydrochloric acid) nyob rau hauv qis kub thiab tsis tshua muaj concentration tej yam kev mob, Monel alloys muaj zoo corrosion kuj (oxidizing acids yuav ua kom lawv corrosion).
Cov tshuaj ntsev: Lawv tuaj yeem tiv taus corrosion los ntawm ntau cov tshuaj chloride ntsev, thiab tsis ua rau corrosion tsis ua hauj lwm los ntawm chloride ions.
2. Dab tsi yog qhov tseem ceeb tsis xws li qhov ntom ntom thiab melting point ntawm Monel alloys?
Rau lwm qib (piv txwv li, Monel K500, Monel 404), qhov tsis sib xws yuav txawv me ntsis vim qhov sib txawv ntawm kev sib xyaw thiab cov txheej txheem kho cua sov.
