Qhov ntom

 

Qhov ceev ntawm DNV LR ABS EH36 nkoj steel phaj zoo ib yam li cov hlau zoo tib yam, kwv yees li 7.85g / cm³. Tus nqi ntom ntom no yog qhov tseem ceeb rau kev suav cov tsis xws li qhov hnyav thiab qhov nruab nrab ntawm lub ntiajteb txawj nqus ntawm lub nkoj hull hauv kev tsim nkoj. Piv txwv li, thaum tsim ib lub nkoj loj loj, qhov tseeb ntawm cov hlau tuaj yeem pab cov kws ua haujlwm hauv kev kwv yees qhov hnyav ntawm cov hlau ntawm lub nkoj hull, yog li ua kom muaj kev tsim nyog ntawm cov tsis muaj feem cuam tshuam rau lub buoyancy thiab stability ntawm lub nkoj. .

 

Thermal Properties

 

Coefficient ntawm Thermal Expansion: EH36 nkoj steel phaj muaj ib coefficient ntawm thermal expansion. Nws yuav nthuav dav lossis cog lus sib haum nrog kev hloov pauv ntawm qhov kub thiab txias. Nws coefficient ntawm thermal expansion yog kwv yees li 12 × 10⁻⁶ / degree (nyob rau hauv thaj tsam ze li ib txwm kub). Qhov no txhais tau hais tias thaum lub nkoj caij nkoj los ntawm thaj chaw hiav txwv txias mus rau thaj chaw sov sov, cov phaj hlau yuav nthuav dav vim qhov kub thiab txias. Yog tias qhov tseem ceeb no tsis raug txiav txim siab thaum lub nkoj tsim qauv tsim thiab txheej txheem kev tsim kho, nws tuaj yeem ua rau cov txheej txheem deformation, weld tawg thiab lwm yam teeb meem.

Thermal conductivity: Lub thermal conductivity ntawm cov hlau phaj no muaj qee yam cuam tshuam rau lub tshav kub rwb thaiv tsev thiab hluav taws kub - pov thawj ntawm lub nkoj. Nws muaj peev xwm ua tau cua sov thiab tuaj yeem hloov cov cua sov hauv cov hlau. Lub thermal conductivity yog kwv yees li 40 - 50W / (m・K) (tus nqi tshwj xeeb yuav txawv me ntsis vim yog yam xws li microstructure thiab impurities ntawm hlau). Nyob rau hauv lub tshav kub - rwb thaiv tsev tsim ntawm lub nkoj, kev nkag siab txog thermal conductivity ntawm EH36 steel phaj tuaj yeem pab hauv kev xaiv cov cua sov uas tsim nyog - cov ntaub ntawv rwb thaiv tsev kom txo tau cov cua sov. Piv txwv li, qhov tseem ceeb no yuav tsum tau xav txog nyob rau hauv kev tsim ntawm lub bulkhead nyob ib ncig ntawm lub cav chav tsev thiab lwm yam cua sov - tsim cov cheeb tsam ntawm lub nkoj.

 

 

 

Acoustic Properties

 

Hais txog acoustics, cov yam ntxwv ntawm EH36 steel phaj kuj tseem ceeb heev. Nws muaj qee lub suab nrawm thiab acoustic impedance thaum lub sij hawm nthuav tawm ntawm lub suab tsis. Lub suab nrawm hauv cov hlau yog qhov siab, kwv yees li 3000 - 6000m / s (tus nqi tshwj xeeb txawv ntawm cov khoom xws li cov qauv sab hauv ntawm cov hlau). Hauv kev tsim nkoj, tshwj xeeb tshaj yog rau cov cheeb tsam uas lub suab - rwb thaiv tsev thiab suab nrov - yuav tsum tau txo qis (xws li cov neeg coob nyob hauv lub quarters), kev nkag siab txog cov khoom siv hluav taws xob ntawm cov phaj hlau tuaj yeem pab tau txais cov suab tsim nyog - kev ntsuas rwb thaiv tsev, xws li ntxiv suab. - absorbing cov ntaub ntawv los txo cov suab nrov kis tau tus mob. Nyob rau tib lub sijhawm, thaum siv cov khoom siv acoustic rau kev tshuaj xyuas nkoj (xws li kev kuaj xyuas qhov tsis zoo ntawm ultrasonic), cov cuab yeej acoustic tsis xws li lub suab nrawm thiab acoustic impedance ntawm cov hlau yog qhov tseem ceeb rau kev kuaj xyuas kom raug.
