Cov khoom tseem ceeb thiab cov yam ntxwv ntawm BV Qib A Shipbuilding Steel feem ntau suav nrog:

 

Siab zog: Nws muaj lub zog txaus los tiv thaiv ntau yam kev ntxhov siab thiab kev thauj khoom uas tau ntsib los ntawm cov nkoj thaum lub sijhawm ua haujlwm, xws li qhov hnyav ntawm lub nkoj, cov khoom thauj, thiab lub zog ntawm lub hiav txwv.

Zoo Toughness: Muaj peev xwm nqus tau lub zog thiab tiv thaiv kev cuam tshuam thiab kev thauj khoom sai sai yam tsis muaj kev puas tsuaj, txhim kho kev nyab xeeb thiab kav ntev ntawm lub nkoj cov qauv.

Weldability: Tso cai rau kev vuam yooj yim thiab txhim khu kev qha thaum lub sij hawm tsim cov txheej txheem nkoj, ua kom muaj kev ncaj ncees ntawm cov pob qij txha welded thiab tag nrho cov qauv.

Corrosion Resistance: Muaj qee qhov kev tiv thaiv corrosion nyob rau hauv marine ib puag ncig kom ntev lub neej kev pab cuam ntawm lub nkoj.

Hais txog kev kho saum npoo, ntau txoj hauv kev rau shipbuilding steel muaj xws li:

 

Txhaj tshuaj tiv thaiv: Txhawm rau ntxuav cov hlau saum npoo, tshem tawm xeb, nplai, thiab lwm yam kab mob, thiab tsim kom muaj qhov ntxhib saum npoo kom zoo dua adhesion ntawm coatings.

Kev pleev xim: Siv cov tshuaj tiv thaiv corrosion los tiv thaiv cov hlau los ntawm corrosion nyob rau hauv marine ib puag ncig. Cov txheej txheem sib txawv nrog cov khoom tshwj xeeb yuav raug siv, xws li primer, intermediate coat, thiab topcoat.

Galvanizing: Qee zaum, galvanizing tuaj yeem ua haujlwm los muab kev tiv thaiv corrosion ntxiv los ntawm kev tsim cov zinc txheej ntawm cov hlau.

 

Cov kev kho saum npoo tshwj xeeb thiab cov kev xav tau yuav txawv nyob ntawm lub nkoj siv ib puag ncig, kev tsim qauv, thiab tus tswv qhov tshwj xeeb. Kev kho deg yog qhov tseem ceeb los xyuas kom meej qhov kev ua haujlwm ntev thiab ua haujlwm ntev ntawm lub nkoj cov qauv.
