ABS Qib Eh36 Hlau Phaj Rau Shipbuilding

Refining nplej muaj qhov cuam tshuam tseem ceeb hauv qab no rau kev tiv thaiv corrosion ntawm nkoj tsim steel daim hlau:

I. Cov ntsiab cai rau kev txhim kho corrosion
Txo qhov nyiam ntawm grain ciam corrosion:
Refining nplej zoo heev nce tus naj npawb ntawm cov ciam teb. Cov ciam teb nplej feem ntau tsis muaj kev sib txuas hauv cov txheej txheem corrosion vim tias qhov kev npaj atomic ntawm cov ciam teb yog qhov tsis sib xws thiab muaj zog dua, ua rau nws yooj yim dua rau cov tshuaj tiv thaiv tshwm sim. Txawm li cas los xij, thaum cov nplej tau ua kom zoo, cov ciam teb ua kom zoo dua thiab sib npaug ntau dua. Qhov no ua rau txoj kev diffusion ntawm corrosive xov xwm ntawm cov ciam teb nplej ntau nyuaj thiab tortuous, yog li slowing down lub ntxeem tau ceev ntawm corrosive media. Piv txwv li, nyob rau hauv lub marine ib puag ncig, rau corrosive media xws li seawater nkag mus rau hauv lub steel phaj, nws yuav tsum tau mus dhau los ntawm ntau nplua nplej ciam teb, ua rau kom qhov nyuaj thiab txo tau ntawm grain ciam corrosion.
Nyob rau tib lub sijhawm, cov ciam teb ua kom zoo tuaj yeem cuam tshuam zoo dua rau kev sib kis ntawm cov ions corrosive thiab txo qis hauv zos corrosion ntawm cov ciam teb. Piv txwv li, corrosive ions xws li chloride ions diffuse sai heev nyob rau hauv coarse-grained lug thiab yooj yim concentrated ntawm grain ciam teb thiab ua rau corrosion. Nyob rau hauv lub nkoj tsim steel daim hlau nrog refined nplej, vim lub refinement thiab uniform faib ntawm grain ciam teb, lub diffusion ntawm chloride ions yog ntau heev hindered, txo cov concentration ntawm chloride ions ntawm grain ciam teb thiab yog li txo cov degree ntawm corrosion hauv zos.

 

 

 

Txhim kho qhov ruaj khov ntawm cov yeeb yaj kiab passivation:
Refining nplej pab tsim cov denser thiab ruaj khov passivation zaj duab xis ntawm cov hlau phaj nto. Nyob rau hauv ib puag ncig marine, ib txheej ntawm oxide zaj duab xis, piv txwv li, zaj duab xis passivation, yuav tsim nyob rau saum npoo ntawm shipbuilding steel daim hlau, uas tuaj yeem tiv thaiv corrosive xov xwm los ntawm kev tiv tauj cov hlau phaj ntxiv thiab ua lub luag haujlwm tiv thaiv. Thaum cov nplej tau ua kom zoo dua qub, tus naj npawb ntawm cov chaw ua haujlwm ntawm cov hlau phaj nto nce, uas yog qhov tsim nyog rau kev tsim cov yeeb yaj kiab passivation. Cov qauv ua kom zoo zoo ua rau cov ntawv cog lus passivation zaj duab xis ntau dua nrog cov matrix thiab txhim kho kev ruaj ntseg ntawm cov yeeb yaj kiab passivation. Piv txwv li, nyob rau hauv cov ntaub ntawv ntawm yoj cuam tshuam thiab dej hiav txwv immersion, passivation zaj duab xis nyob rau saum npoo ntawm shipbuilding steel daim hlau nrog refined nplej yuav zoo dua tiv thaiv kev puas tsuaj ntawm sab nraud quab yuam thiab yaig ntawm corrosive media, prolonging lub sij hawm tiv thaiv ntawm passivation zaj duab xis thiab yog li txhim kho corrosion kuj ntawm steel phaj.

II. Qhov zoo ntawm kev siv tswv yim
Extending lub neej kev pab cuam:
Rau cov nkoj ua haujlwm nyob rau hauv ib puag ncig marine rau lub sijhawm ntev, kev tiv thaiv corrosion yog qhov tseem ceeb ntawm kev ua tau zoo. Shipbuilding steel daim hlau nrog refined nplej muaj zoo corrosion kuj, uas yuav txo tau lub thinning ntawm steel phaj thickness thiab structural puas los ntawm corrosion thiab ntev kev pab cuam lub neej ntawm ships. Piv txwv li, lub nkoj thauj khoom tsim nrog shipbuilding steel daim hlau nrog refined nplej muaj qhov txo qis corrosion ntawm lub hull tshaj li lub nkoj thauj khoom siv cov phaj hlau zoo tib yam nyob rau hauv tib lub marine ib puag ncig thiab kev siv, yog li txo qhov zaus ntawm kev saib xyuas thiab hloov cov hlau. phaj thiab txo cov nqi khiav haujlwm.
Tsis tas li ntawd, nyob rau hauv qee qhov tshwj xeeb marine engineering teb xws li offshore roj platforms thiab submarine pipelines, tsis tshua muaj siab yuav tsum tau ua rau corrosion kuj ntawm cov ntaub ntawv. Shipbuilding steel phaj nrog refined nplej kuj tseem tuaj yeem ua lub luag haujlwm tseem ceeb hauv cov teb no thiab txhim kho kev ntseeg tau thiab kev nyab xeeb ntawm engineering chaw.
