CovNtsev Corrosion Spray Test Chambertuaj yeem soj ntsuam lub peev xwm ntawm ntsev tsuag corrosion ntawm cov ntaub ntawv thiab lawv cov txheej txheem tiv thaiv, nrog rau cov txheej txheem zoo sib piv ntawm cov txheej txheem tiv thaiv zoo sib xws, thiab tib lub sijhawm tuaj yeem ntsuas lub peev xwm ntawm qee cov khoom los tiv thaiv ntsev tsuag corrosion;
LIB Salt Spray Test Chambers tuaj yeem ua cov kev sim no
Muaj 4 hom kev ntsuam xyuas uas cov ntsev tsuag tshuaj tsuag tuaj yeem ua tau:
▶ Ntsuag Ntsej Muag
Qhov ntsuas kub ntawm qhov nruab nrab ntsev tsuag tshuaj ntsuam (NSS) chav kuaj yuav tsum yog (35 ± 2) degree, cov av noo ntau dua 95 feem pua, cov huab txo qis yog 1 ~ 2mL / 80cm * h , thiab lub nozzle siab yog 78.5 ~ 137.3kPa (0.8 ~ 1.4kgf / cm2). Hauv chav kuaj tshuaj ntsev ntsev, cov dej ntsev uas muaj (5 0.5) feem pua sodium chloride thiab pH tus nqi ntawm 6.5 ~ 7.2 yog txau los ntawm cov cuab yeej tshuaj tsuag, kom cov ntsev tsuag nyob rau hauv daim ntawv xeem, thiab nto corrosion xeev yog pom tom qab ib lub sij hawm ntawm lub sij hawm.
▶ Copper Accelerated Acetic Acid Salt Spray
Copper-accelerated acetate mist test (CASS) yog ntxiv cov tooj liab chloride 2 hydrate rau 5 feem pua sodium chloride brine raws li kev ntsuas ntsev dav dav kom ua kom cov concentration ntawm 0.26g / L, thiab tom qab ntawd kho cov PH nrog acetic acid los ua tus nqi pH ntawm cov ntsev ntsev sau cov tshuaj 3.1-3.3. (Test xa mus rau GB / T 10125 khoom cua cua corrosion test)
▶ Alternating ntsev tsuag tshuaj ntsuam
Alternating ntsev tsuag tshuaj ntsuam yog ib qho kev ntsuam xyuas ntsev tsuag (tso pom tau los ntawm kev hloov ntsev tsuag tshuaj ntsuam chamber.
▶ Acetic Acid ntsev tsuag
Cov tshuaj acetate spray test (ASS test) tau tsim los ntawm kev kuaj tshuaj ntsev nruab nrab. Nws yog ntxiv ib co glacial acetic acid rau 5 feem pua sodium chloride tov.
