Hauv kev ua si ntawm marine engineering thiab cov cuab yeej siv high-akas tsim, enicu -7}}}} cov ntaub ntawv me me-tooj liab A5.11 tus qauv, txuas ntxiv mus ua si ib lub luag haujlwm IRSplacleable. Qhov kev siv vuam ua laj thawj ua raws li ISO 14172: 2016 Cov qauv kev sib tw thoob plaws yog nieccess rau 62%, thiab feter tsawg dua lossis sib npaug ntawm 2.5%. Nrog nws cov cim corrosion tsis kam, nws tau dhau los ua qhov nruab nrab tseem ceeb rau txuas cov khoom tseem ceeb.
Cov khoom siv tau muab ntawv pov thawj
Raws li cov ntaub ntawv cov ntaub ntawv ntawm American Vuam Societ (AWS), qhov tseeb ntawm {degring cov khoom siv uas muaj tsawg dua li ntawm 150 qib kev sib tw ntawm cov khoom siv 30mds). Cov xeeb ceem no yog vim yog cov nyhuv synergistic ntawm nws npib tsib xee thiab cov paib tooj liab, uas tuaj yeem tsim cov zaj yeeb yaj kiab uas ruaj khov rau hauv Cleal ib puag ncig Ion.
Ib qho kev sib piv ntawm 2021 los ntawm Lub Chaw Haujlwm Saib Xyuas Kev Nyab Xeeb ntawm cov khoom siv dej hiav txwv, qhia txog cov khoom siv roj ntsha ua rau muaj kev sib cav sib ceg, ua kom pom tseeb nws txoj kev ntseeg tau ntev hauv lub nkoj marine.
■ Muaj daim ntawv thov yog kev hloov siab nce qib
Hauv kev ua haujlwm ntawm cov ntaub ntawv pej xeem los ntawm Hudong-Zhonghua tuam txhab ua kua rau ntawm lub 174,}} kev sib txuas. Cov txheej txheem dawb ntawm hyundai hnyav kev lag luam ntawm Kauslim Kauslim qhia tias cov khoom siv tuaj yeem ua rau muaj kev cuam tshuam hluav taws xob ntau tshaj 54J hauv kev tsim kho sab nrauv Polar.
Nyob rau hauv thaj teb ntawm lub zog nuclear, Fabkis cov framatome tau txais ASMENE III Nuclear Fais Fab Fircuities System ntawm cov tshuab hluav taws xob cov tshuaj tiv thaiv dej. Kuv lub teb chaws General Nuclear lub zog Engine kuj tseem ua tiav cov khoom no hauv kev saib xyuas dej hiav txwv ntawm yangjiang nuclear zog hluav taws xob.
■ Technology hloov kho lwm qhov zuj zus ntxiv kom tob dua
Kev tshawb nrhiav kev lag luam tam sim no thiab kev nthuav dav tsom rau cov txheej txheem optimization. Harbin Vuam Tshawb Nrhiav Lub Koom Haum 2 {{1} {}}}} sulfuric acid tuaj yeem nce li 22%. Sandvik pab pawg qhov tseeb enicu -7- g vuam hlau cov khoom lag luam tau ntau lawm ntawm 1.2mm nplua ntau lawm ntawm cov neeg hlau txua vuam vuam vuam.
■ Tus qauv txheem tau yooj yim zuj zus
National Vieforization Pawg Neeg Kawm Ntawv (SAC / TC55) Tso cov khoom siv ua kom sov " Kev kho mob yuav tsum tau tom qab vuam. Cov cua ntsawj ntshab tsis tau tsim los ntawm cov koom haum thoob ntiaj teb rau cov qauv (ISO) tau ntxiv ib txoj kev xeem rau cov khoom siv hydrogen.
Ciaj Kev Ua Lag Luam Kev Ua Lag Luam thiab Kev Sib Tw
Raws li kev txheeb cais los ntawm Tuam Tshoj Tuam Tshoj vuam, kuv lub teb chaws kev noj ntawm ob lub teb chaws-raws li cov ntaub ntawv vuam yuav ncav cuag 1822, ntawm uas enicu {{series} series account rau li 15%. Nrog kev nce qib ntawm cov phiaj xwm tseem ceeb xws li kev txhim kho cov dej hiav txwv Txawm li cas los xij, nws tseem tab tom muaj cov lag luam ntim cov roj uas muaj xws li cov hlau vuam (txog 380 Yuan / kg) thiab kev kawm ntev ntawm vuam cov neeg ua haujlwm.
Kev lag luam hauv cov neeg lag luam sab hauv cov ntaub ntawv taw qhia tias kev txhim kho txuas ntxiv ntawm enicu {{tseev kom muaj kev sib koom tes ntawm cov khoom lag luam, kev tshawb fawb txog cov neeg siv thiab cov neeg siv kev tshawb fawb. Tsis ntev los no, "cov khoom siv marrine vuam kab ke" sib koom tes ua ke cov hlau tshwj xeeb (ntau dua 50 hli
