Kev kuaj cov tshuaj sulfur dioxide corrosion yog ib qho kev kuaj sim uas siv los ntsuas qhov kev tiv thaiv corrosion ntawm cov ntaub ntawv nyob rau hauv acidic gas tej yam kev mob. Qhov kev ntsuam xyuas no feem ntau yog siv rau hauv kev lag luam tsheb thiab aerospace los ntsuas qhov ua haujlwm ntev ntawm cov khoom siv hauv cov kav dej, cov cav, thiab cov khoom siv dav hlau.
Thaum lub sij hawm kev xeem, cov qauv ntawm cov khoom raug kuaj yog raug rau ib qho chaw tswj ntawm sulfur dioxide roj ntawm ib tug tshwj xeeb kub thiab av noo. Cov pa roj sai sai corrodes cov ntaub ntawv, uas tso cai rau cov kws tshawb fawb los ntsuas tus nqi ntawm corrosion.
Qhov kev sim pab txiav txim siab qhov tsim nyog ntawm cov ntaub ntawv siv rau hauv ib puag ncig hnyav thiab tuaj yeem pab xaiv cov khoom siv rau kev siv tshwj xeeb. Nws tseem tuaj yeem muab cov ntaub ntawv tseem ceeb ntawm kev ua haujlwm ntawm kev tiv thaiv txheej thiab kev kho deg.
Cov txiaj ntsig ntawm kev sim tshuaj sulfur dioxide tuaj yeem qhia rau cov tuam txhab, cov kws tsim khoom, thiab cov kws tshawb fawb txog kev txhim kho thiab tsim cov ntaub ntawv tshiab kom tiv taus qhov hnyav thiab corrosive ib puag ncig yam tsis muaj kev cuam tshuam kev nyab xeeb thiab kav ntev.
Dab tsi yog cov qauv thoob ntiaj teb rau kev kuaj sulfur dioxide corrosion?
Sulfur dioxide paub tias ua rau corrosion nyob rau hauv ntau yam ntaub ntawv, xws li hlau, plastics, thiab ceramics. Txhawm rau kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov khoom lag luam hauv kev lag luam sib txawv, cov qauv thoob ntiaj teb tau tsim los rau kev sim cov khoom siv rau sulfur dioxide corrosion. Hauv tsab xov xwm no, peb yuav tham txog cov qauv thoob ntiaj teb rau kev kuaj sulfur dioxide corrosion.
- TS EN ISO 3231: 2016 - Cov menyuam roj hmab npog - Kev txiav txim siab ntawm kev ua haujlwm ntawm atmospheric ozone, ultraviolet hluav taws xob, thiab sulfur dioxide
TS EN ISO 3231: 2016 Cov qauv kev lees paub dav dav rau kev ntsuas qhov tsis kam ntawm cov roj hmab npog cov menyuam rau atmospheric ozone, ultraviolet hluav taws xob, thiab sulfur dioxide. Tus qauv qhia txog cov txheej txheem rau kev nthuav tawm cov qauv roj hmab mus rau qhov chaw tswj hwm uas muaj cov ntsiab lus tshwj xeeb ntawm sulfur dioxide rau lub sijhawm. Cov qauv tom qab ntawd raug tshuaj xyuas cov cim qhia ntawm kev tawg, tawg, lossis lwm yam kev puas tsuaj.
- ASTM G85 - Txuj Kev Xyaum rau Kev Hloov Kho ntsev tsuag (Fog) Kev Ntsuas
ASTM G85 yog tus qauv siv dav rau kev ntsuas qhov kev tiv thaiv corrosion ntawm cov khoom siv hlau, suav nrog cov khoom siv coated thiab tsis muaj coated, raug rau sulfur dioxide. Tus txheej txheem suav nrog kev nthuav tawm cov qauv kuaj mus rau cov huab cua ntsev ntxiv nrog cov roj sulfur dioxide ntxiv rau lub sijhawm. Tom qab ntawd cov qauv raug tshuaj xyuas rau kev puas tsuaj corrosion.
- ISO 6988:1985 - Hlau thiab lwm yam uas tsis yog-organic coatings - Kev ntsuas sulfur dioxide nrog dav dav condensation ntawm noo noo
TS EN ISO 6988: 1985 qhia txog cov txheej txheem ntsuas kev ntsuas kev tiv thaiv corrosion ntawm cov hlau thiab lwm yam tsis-organic txheej rau sulfur dioxide. Kev sim yog ua los ntawm kev nthuav tawm cov qauv kuaj coated rau ib qho chaw sulfur dioxide nrog noo noo rau lub sijhawm. Cov qauv raug soj ntsuam rau txhua qhov degradation lossis corrosion puas.
- TS EN ISO 9227: 2017 - Kev ntsuas corrosion hauv cov huab cua tsim khoom - Kev ntsuas ntsev tsuag
TS EN ISO 9227: 2017 Cov txheej txheem lees paub dav dav rau kev sim tshuaj tiv thaiv corrosion ntawm cov khoom siv hlau raug rau cov tshuaj ntsev uas muaj sulfur dioxide. Qhov kev ntsuam xyuas no suav nrog kev nthuav tawm cov khoom siv hlau mus rau qhov chaw ntsev ntsev rau lub sijhawm teev tseg, tom qab ntawd cov qauv raug soj ntsuam rau kev puas tsuaj corrosion.
