Corrosion yog ib qho kev sib tw loj rau cov khoom sib txuas hauv qab dej, uas raug cuam tshuam rau cov dej hiav txwv hnyav. Kev tiv thaiv corrosion yog qhov tseem ceeb rau kev ua kom lub neej ntev thiab kev ntseeg siab ntawm cov connectors no. Kab lus no tshawb nrhiav cov tswv yim zoo los tiv thaiv cov kab txuas hauv qab dej los ntawm kev xeb.
Kev siv cov khoom siv Corrosion-Resistant
Stainless hlau thiab titanium
Siv cov khoom siv tiv thaiv corrosion zoo li stainless hlau thiab titanium hauv kev tsim cov khoom siv hauv qab dej tuaj yeem txo qhov kev pheej hmoo ntawm corrosion. Cov ntaub ntawv no muaj kev tiv thaiv zoo rau cov xwm txheej hnyav ntawm thaj chaw marine, txhim kho cov kav ntev ntawm cov khoom sib txuas.
Tshwj xeeb Alloys
Cov alloys tshwj xeeb, xws li npib tsib xee los yog tooj liab-nickel alloys, yog tsim los tiv thaiv corrosive los ntawm seawater. Cov ntaub ntawv no muab ib txheej ntxiv ntawm kev tiv thaiv corrosion, ua kom cov connectors tswj lawv cov kev ncaj ncees nyob rau lub sij hawm.
Cov txheej txheem tiv thaiv
Anodizing
Anodizing yog txheej txheem electrochemical uas ua rau kom cov tuab ntawm cov txheej txheem oxide nyob rau saum npoo ntawm cov hlau. Cov txheej no ua raws li kev tiv thaiv kev tiv thaiv corrosion, txhim kho cov kav dej hauv qab dej txuas.
Epoxy txheej
Epoxy txheej yog dav siv los tiv thaiv underwater connectors los ntawm corrosion. Cov coatings no muab ib qho kev tiv thaiv zoo uas tiv thaiv cov dej hiav txwv los ntawm kev sib cuag ncaj qha nrog cov hlau, yog li txo qhov kev pheej hmoo ntawm corrosion.
Sealing thiab Encapsulation
O-Rings thiab Gaskets
O-rings thiab gaskets ua los ntawm cov khoom zoo, corrosion-resistant cov ntaub ntawv tuaj yeem ua tau zoo sealing underwater connectors, tiv thaiv dej ingress thiab txo txoj kev pheej hmoo ntawm corrosion. Kev sib khi kom zoo kom ntseeg tau tias cov khoom siv sab hauv ntawm cov khoom sib txuas tseem qhuav thiab tiv thaiv.
Encapsulation
Encapsulation suav nrog kev kaw tag nrho cov khoom sib txuas hauv cov khoom siv tiv thaiv, xws li silicone lossis polyurethane. Txoj kev no muab kev tiv thaiv kev tiv thaiv corrosion, tiv thaiv ob qho tib si sab nraud thiab sab hauv ntawm cov khoom sib txuas.
Kev tiv thaiv Cathodic
Kev txi Anodes
Sacrificial anodes, ua los ntawm cov ntaub ntawv xws li zinc lossis txhuas, tuaj yeem txuas rau hauv qab dej txuas. Cov anodes corrode es tsis txhob ntawm cov connectors, muab ib daim ntawv ntawm cathodic tiv thaiv. Txoj kev no muaj txiaj ntsig zoo hauv kev ncua lub neej ntawm underwater connectors los ntawm kev tiv thaiv corrosion.
Impressed Current Cathodic Protection (ICCP)
ICCP systems siv lub zog hluav taws xob los muab kev tiv thaiv txuas ntxiv mus rau cov khoom txuas hauv qab dej. Txoj kev no ua kom ntseeg tau tias cov khoom sib txuas tseem muaj kev tiv thaiv los ntawm kev xeb dhau lub sijhawm ntev, txawm tias nyob rau hauv ib puag ncig corrosive heev.
Tsis tu ncua thiab tshuaj xyuas
Kev soj ntsuam niaj hnub
Kev tshuaj xyuas tsis tu ncua ntawm cov khoom sib txuas hauv qab dej tuaj yeem pab txheeb xyuas cov cim ntxov ntawm corrosion. Kev tshawb pom raws sij hawm tso cai rau kev kho kom raug ua ntej kev puas tsuaj loj tshwm sim.
Cov kev pab tu
Ua raws li kev saib xyuas zoo uas suav nrog kev tu, rov txheej dua, thiab hloov cov ntsaws ruaj ruaj puas tuaj yeem txo qhov kev pheej hmoo ntawm corrosion. Kev saib xyuas tsis tu ncua ua kom ntseeg tau tias cov kev tiv thaiv kev tiv thaiv tseem siv tau raws sijhawm.
Xaus
Kev tiv thaiv underwater connectors los ntawm corrosion yog ib qho tseem ceeb rau kev tswj lawv kev cia siab rau thiab ncua lawv lifespan. Los ntawm kev siv cov khoom siv tiv thaiv corrosion, siv cov txheej txheem tiv thaiv, ua kom muaj kev sib khi kom zoo, ua haujlwm cathodic tiv thaiv, thiab ua haujlwm tsis tu ncua, cov neeg ua haujlwm tuaj yeem txo qhov kev pheej hmoo ntawm corrosion thiab txhim kho kev ua haujlwm ntawm cov khoom siv hauv qab dej.
