CASS Test Chamber, cov cuab yeej tshwj xeeb rau kev xeem CASS, yog cov khoom lag luam tshiab tshaj plaws tau tsim los ntawm cov khoom siv tshuaj tua ntsev nruab nrab.
CAS yog dab tsi
CASS yog qhov tsim tshiab sai ntsev tsuag tshuaj tiv thaiv corrosion. Nws ua rau kev siv cov yam ntxwv ntawm cov electrode loj muaj peev xwm sib txawv ntawm tooj liab ntsev thiab steel qhov chaw thiab cov nickel txheej kom ceev cov corrosion ntawm txheej. Nws yog thawj zaug siv los kuaj nickel, tooj liab, lossis chromium hniav txheej plated rau ntawm cov hlau.
Vim li cas peb thiaj xeem CASS
Simulated ntsev tsuag kuaj muaj xws li:
(1) Tsis siv neeg ntsev tsuag tshuaj ntsuam (NSS test) yog qhov tshwm sim ntxov tshaj plaws ntawm daim ntawv thov tam sim no ntawm kev siv dav tshaj plaws los ua kom cov txheej txheem kuaj corrosion. Nws siv 5 feem pua ntawm sodium chloride brine tov, tshuaj pH kho nyob rau hauv nruab nrab ntau yam (6 ~ 7) raws li ib tug tshuaj tsuag nrog tshuaj. Kev ntsuas kub yog coj 35 degree, qhov yuav tsum tau sib hais haum tus nqi ntawm ntsev tsuag nyob rau hauv 1 ~ 2ml / 80cm2.h ntawm.
(2) Acetate ntsev test (ASS test) yog tsim los ntawm kev ntsuas nruab nrab ntsev pos huab. Nws yog nyob rau hauv 5 feem pua sodium chloride tov nrog ib co glacial acetic acid, thiaj li hais tias cov tshuaj PH nqi mus txog 3, cov tshuaj yuav acidic, qhov kawg tsim ntawm ntsev tsuag kuj los ntawm nruab nrab ntsev tsuag rau acidic. Nws tus nqi corrosion yog kwv yees li 3 npaug sai dua qhov kev xeem NSS.
(3) Copper accelerated salt spray test (CASS test) yog ib qho tshiab uas tsim tawm txawv teb chaws ceev ntsev tsuag corrosion test, ntsuas kub ntawm 50 degree, ntsev tov nrog me me ntawm tooj liab ntsev - tooj liab chloride, muaj zog induced corrosion.
Qhov ntsuas Copper Accelerated Salt Spray yog piv nrog qhov nruab nrab ntsev tsuag tshuaj ntsuam vim qhov ntsuas kub tau nce ntawm 35 degree mus rau 50 degree. Ua ke nrog cov nyhuv nrawm ntawm tooj liab ntsev ntawm corrosion, tus nqi corrosion yog nce los ntawm 7 mus rau 8 zaug, thiab nws tseem yog 2 mus rau 3 zaug sai dua li cov tshuaj tsuag acetate. Lub sijhawm xeem tau pom tseeb luv luv, txuag tau ntau tus neeg ua haujlwm, nyiaj txiag thiab khoom siv.
Yuav ua li cas kuaj CASS
Kev Xeem Xeem:
1. Cov tshuaj ntsev: 5 feem pua sodium chloride tov yog npaj.
2. Copper sulfate tov: A 0.26 feem pua tooj liab sulfate tov yog npaj thiab ntxiv rau cov ntsev tov.
3. Cov qauv kuaj: Ib qho qauv huv thiab qhuav ntawm cov khoom nyob rau hauv kev sim raug xaiv.
4. Kev kuaj chamber: Ib chav kuaj tsim nyog yuav tsum tau ua kom muaj qhov ntsuas kub, av noo, thiab raug rau qhov kev sim.
5. Cov cuab yeej kaw lus: Cov cuab yeej ntsuas ntsuas ntsuas kub, av noo, thiab cov tshuaj tsuag yog tsim nyog.
Cov txheej txheem xeem:
1. Cov chav kuaj tau teeb tsa thiab ntsuas qhov ntsuas kub thiab av noo xav tau.
2. Cov tshuaj ntsev yog npaj raws li qhov yuav tsum tau ua thiab cov tshuaj tooj liab sulfate ntxiv rau nws.
3. Cov qauv kuaj yog ntsuas thiab cim rau kev txheeb xyuas.
4. Cov qauv raug muab tso rau hauv chav kuaj ntawm lub kaum sab xis 15-degree.
5. Cov tshuaj tsuag ntsev yog txau rau ntawm cov qauv kuaj ntawm tus nqi ntawm 1-2 ml ib teev.
6. Qhov ntsuas kub ntawm chav kuaj yog tswj ntawm 50 degree ntxiv /- 2 degree thiab cov av noo yog khaws cia ntawm 95 feem pua plus /- 5 feem pua.
7. Cov qauv kuaj tau raug soj ntsuam tas li rau lawv qhov kev ua tau zoo thiab cov ntaub ntawv khaws cia.
8. Qhov kev ntsuam xyuas tau txuas ntxiv rau lub sijhawm teev tseg, feem ntau 24–48 teev, raws li tus qauv xeem tau ua raws.
9. Kev sim ua tiav, thiab cov qauv raug tshem tawm, qhuav, thiab tshuaj xyuas cov pov thawj ntawm corrosion.
10. Cov qauv 'corrosion qib yog tom qab ntsuas thiab muab piv rau cov kev lees paub raws li tus qauv ntsuas.
Hauv kev xaus, kev ntsuas tooj liab-accelerated ntsev tsuag yog ib txoj hauv kev zoo los ntsuas qhov tsis kam ntawm cov ntaub ntawv rau corrosion. Simulating ib puag ncig hnyav los ntawm qhov kev sim no tuaj yeem pab txhim kho kev ua haujlwm ntev thiab lub neej ntev ntawm cov ntaub ntawv tseem ceeb rau ntau yam kev lag luam. Nws yog ib qho tseem ceeb uas yuav tsum tau ua raws li cov kev cai xeem thiab cov txheej txheem ua tib zoo kom ua tiav qhov kev xeem raug.
