Ntsej Tsuag Test Standard

Nyob rau hauv cov tshuaj tsuag tshuaj ntsev chamber, cov tshuaj tsuag ntsev yog ua. Nws feem ntau yog siv los ntsuas cov hlau 'kev tiv thaiv corrosion lossis corrosion kuj ntawm electroplated hlau nto. Txau corrosive ntsev daws tuaj yeem siv los ua kev kuaj corrosion. Qhov kev ntsuam xyuas yog ua los ntawm kev siv roj, thiab ntau cov txheej txheem corrosion yog ua haujlwm nyob ntawm qhov chaw siv tshwj xeeb. Muaj qhov tseem ceeb ntawm cov qauv ntsuas thiab ntsuas ntsuas kev txiav txim siab thaum ua cov tshuaj ntsev ntsev. Muaj plaub txoj hauv kev los txiav txim siab txog kev ntsuas ntsev ntsev qhov kev tiv thaiv corrosion. Kev ntsuam xyuas, kev ntsuam xyuas txoj kev, kev ntsuam xyuas ntawm corrosion tsos, thiab kev ntsuam xyuas ntawm corrosion cov ntaub ntawv txheeb xyuas kev txheeb xyuas. Cov kev txheeb xyuas ntawm cov ntaub ntawv corrosion muaj cov txheej txheem los tsim cov kev ntsuam xyuas corrosion, ntsuas cov ntaub ntawv corrosion, thiab kwv yees qhov kev ntseeg siab ntawm cov ntaub ntawv corrosion. Nws feem ntau yog siv rau kev txheeb xyuas corrosion thiab kev txheeb cais, tsis yog rau kev ntsuas qhov zoo ntawm cov khoom tshwj xeeb.

Kaum theem ua tus qauv ntsuas tshuaj ntsev, uas yog raws li cov qauv kev sim ua lag luam raws li kev qhia thiab sib haum rau qhov xwm txheej tiag tiag.

Qib 10: Tsis muaj qhov tsis zoo, qhov A rau qhov zoo li, thiab tsis muaj kev hloov kho rau tus qauv saum npoo zoo;

Qib 9: Cov qauv ntawm qhov chaw muaj qhov me me mus rau nruab nrab ntawm cov xim tsis muaj xim, qhov feem pua ​​​​ntawm qhov tsis xws luag yog tsawg dua 1 feem pua, thiab qhov kev ntsuam xyuas zoo li B;

Qib 8: Cov qauv saum npoo yog qhov tsis muaj xim tsis zoo lossis muaj cov xeb me me, qhov zoo li qhov qhab nia C, thiab qhov seem ntawm qhov tsis xws luag yog nyob nruab nrab ntawm 0.1 feem pua ​​thiab 0.25 feem pua; Qib 7: Qhov feem pua ​​​​ntawm qhov chaw txhaum yog li ntawm 0.25 mus rau 0.5 feem pua, qhov kev ntsuam xyuas pom yog D, thiab qhov kev ntsuam xyuas rau lub teeb poob loj ntawm tus qauv qhov chaw qhia tsis tshua muaj cov khoom siv corrosion. ;

Qib 6: Cov cheeb tsam tsis zoo suav rau 0.5 feem pua ​​-1.0 feem pua ​​​​ntawm cov qauv tag nrho cov cheeb tsam saum npoo, qhov zoo li qhov ntsuas E, qhov tsis zoo gloss, lossis txheej nyias ntawm cov khoom siv corrosion los yog pitting;

Qib 5: Qhov chaw txhaum yog 1.

Qib 4: Muaj cov khoom siv corrosion tuab lossis pitting corrosion ntawm tus qauv saum npoo, qhov kev ntsuam xyuas zoo li G, thiab qhov chaw tsis xws luag ua rau 2.5 feem pua ​​-5 feem pua ​​​​ntawm tag nrho cheeb tsam;

Qib 3: Muaj pitting hnyav, txheej txheej khoom corrosion tuab heev, thiab qhov kev ntsuam xyuas pom ntawm H. Qhov kev txhaum cheeb tsam suav txog 5 feem pua ​​-10 feem pua ​​​​ntawm cov qauv.

Qib 2: Cov qauv muaj corrosion ntawm lub hauv paus hlau, qhov chaw tsis xws luag yog li ntawm 10 feem pua ​​​​mus rau 25 feem pua, thiab qhov kev ntsuam xyuas pom yog 1.

Theem 1: Ib qho kev xeb loj tshwm sim, thaj tsam qhov txhaum suav txog 25 feem pua ​​​​rau 50 feem pua ​​​​ntawm cov corrosion.
