Corrosion yog ib qho ua rau cov khoom tsis ua haujlwm hauv tsheb, hluav taws xob, dej hiav txwv, aerospace, thiab kev lag luam. Cov txheej txheej uas zoo li nyob sab nraum zoov yuav pib xeb, hlwv, lossis tev tom qab raug ntsev ntev ntev - ib puag ncig cov khoom. Tos lub hlis los yog xyoo rau tej yam ntuj tso corrosion tshwm sim feem ntau impractical thaum lub sij hawm tsim khoom.
Txhawm rau txhawm rau ntsuas qhov nrawm, cov tuam txhab tso siab rau cov qauv ntsuas ntsev pos huab kom rov tsim cov corrosive ib puag ncig hauv qhov chaw kuaj xyuas. Kab lus no piav qhia txog qhov twg ntsev yuav tsum tau rau ASTM B117 Salt Fog Corrosion Testing, yuav ua li cas qhov kev ntsuam xyuas txawv ntawm ntuj raug, thiab yuav ua li cas xaiv ntawm ib qho kev LIB ASTM B117 ntsev Fog Corrosion Test Chamber thiab Cyclic Salt Fog Corrosion Test Chamber.
Ntsev Rau ASTM B117 Salt Fog Corrosion Test: Nkag siab txog Cov Ntsiab Cai
1. Cov ntsev twg yog siv rau ASTM B117, NSS, AASS, thiab CASS Test?
Qhov zoo thiab muaj pes tsawg leeg ntawm ntsev ncaj qha cuam tshuam rau kev kuaj corrosion raug. ASTM B117 thiab ISO 9227 yuav tsum muaj siab - purity sodium chloride (NaCl) tsis muaj kab mob uas tuaj yeem hloov tus cwj pwm corrosion.
Peb txoj kev ntsuas ntsev pos huab tau siv thoob ntiaj teb:
| Hom kev xeem | Kev daws teeb meem | pH ntau | Daim ntawv thov |
|---|---|---|---|
| NSS (Neutral ntsev tsuag) | 5% NaCl Solution | 6.5–7.2 | General corrosion xeem |
| AASS (Acetic Acid Salt Spray) | 5% NaCl + Acetic Acid | 3.1–3.3 | Kho kom zoo nkauj txheej |
| CASS (Copper Accelerated Acetic Acid Salt Spray) | 5% NaCl + Acetic Acid + 0.26 g/L CuCl₂ | 3.1–3.3 | High -kev ua tau zoo plated txheej |
ASTM B117 tshwj xeeb yuav tsum muaj 5% sodium chloride tov npaj nrog dej huv. Cov tshuaj yog atomized ntawm kwv yees li 83 kPa thiab tso rau ntawm 1-2 mL / 80 cm² / teev nyob rau hauv ib chav tsev khaws cia ntawm 35 ± 2 degree.
2. Ntsev Fog Corrosion Test vs. Natural Exposure
Kev kuaj corrosion ntuj yuav xav tau rau lub hlis, ib xyoos, lossis ntau xyoo ua ntej cov txiaj ntsig tseem ceeb tshwm sim. Environmental yam
xws li dej nag, av noo, qhov kub thiab txias, cov pa phem, thiab cov ntug dej hiav txwv tsis tu ncua hloov pauv, ua rau kev sib piv tsis yooj yim.
Salt Fog Corrosion Testing ua kom cov txheej txheem los ntawm kev tsim kom muaj kev tswj hwm ib puag ncig nrog cov tsis ruaj khov. Ntsev concentration, kub, pH tus nqi, tshuaj tsuag tus nqi, thiab lub sij hawm raug nyob ruaj khov nyob rau hauv kev sim. Qhov no tso cai rau cov tuam txhab lag luam kom tau txais cov ntaub ntawv rov ua dua corrosion tsis pub dhau hnub lossis lub lis piam hloov xyoo.
Piv txwv li, lub tsheb kauj vab uas yuav xav tau ib xyoos ntawm ntug hiav txwv raug feem ntau tuaj yeem raug soj ntsuam los ntawm kev ntsuas ntsev kom ceev hauv ob peb puas teev.
3. Kev ua raws li tus qauv thiab kev lag luam daim ntawv thov
ASTM B117 tseem yog qhov dav tshaj plaws lees paub ntsev pos corrosion tus qauv thoob ntiaj teb. Ntau lub lag luam yuav tsum tau ua raws li cov khoom ua ntej cov khoom tuaj yeem nkag mus rau hauv kev lag luam.
