Hais txog kev siv sib txawv ntawm peb lub tuam txhab ntau homntsev tsuag testers

1,Neutral Salt Spray Test (NSS) Txoj kev no yog ib txoj kev sim siv dav hauv Suav teb.Nws yog siv los simulate atmospheric ib puag ncig tej yam kev mob nyob rau hauv ntug hiav txwv dej thiab yog haum rau hlau thiab lawv alloys, hlau coatings, organic coatings, anodic oxide films thiab conversion zaj duab xis, thiab lwm yam. Intermittent saltwater spray yog ze rau marine thiab ntug hiav txwv tej yam kev mob tshaj nruam tsuag.Qhov kev ntsuam xyuas tsis tu ncua tuaj yeem ua rau cov khoom siv corrosion nqus noo noo thiab cuam tshuam rau corrosion.Yog tias lub sijhawm ntawm ob qhov kev txhaj tshuaj ntev txaus, cov khoom siv corrosion yuav qhuav, tawv thiab tawg, uas feem ntau zoo ib yam li qhov tshwm sim uas tshwm sim nyob rau hauv tej yam ntuj tso.Cov txheej ntxeem tau tuaj yeem txau nrog dej ntsev rau lub sijhawm luv luv kom tsis txhob muaj qhov pores tshiab vim yog corrosion.

2,Acetic acid ntsev tshuaj tsuag (ASS test) Rau cov khoom siv plated xws li tsheb tsav tsheb hauv nroog, cov kua qaub (acetic acid) yog ntxiv rau cov ntsev ntsev kom txo lub sijhawm kuaj.Nws yog tsim rau txhua yam inorganic thiab plated thiab coated, dub thiab tsis-ferrous kub, xws li tooj liab-nickel-chromium txheej, npib tsib xee-chromium txheej, anodized zaj duab xis ntawm txhuas ntsev tsuag tshuaj ntsuam qauv, thiab lwm yam. Tsuas yog cov tshuaj npaj yog txawv ntawm qhov nruab nrab ntsev tsuag tshuaj ntsuam, lwm tus yog tib yam.

3,Copper-Accelerated Acetate Spray Test (CASS Test) Los ntawm kev soj ntsuam ntawm cov dej nag hauv cheeb tsam thiab ntau cov kev tshawb fawb ntawm kev sim-accelerating additives, nws tau pom tias ntxiv tooj liab oxide rau cov tshuaj tsuag acetate tuaj yeem ua rau muaj kev cuam tshuam loj ntawm qhov nruab nrab, thiab qhov corrosion Cov yam ntxwv zoo ib yam li cov yam ntxwv ntawm corrosion hnyav nyob rau hauv cov xwm txheej tiag tiag, yog li txoj kev ntsuas CASS nrawm tau tsim ntxiv.
