1. Kev thov hlau thoob ntiaj teb rov qab los nrog kev sib txawv hauv cheeb tsam
Lub Koom Haum Hlau Thoob Ntiaj Teb kwv yees tias kev thov hlau thoob ntiaj teb yuav rov qab los 1.2% rau xyoo 2025, mus txog 1.772 billion tons, uas yog vim muaj kev loj hlob zoo hauv cov teb chaws tshiab xws li Is Nrias teb (+8%) thiab kev ruaj khov hauv cov lag luam tsim kho. Txawm li cas los xij, kev thov hlau ntawm Tuam Tshoj yuav poob qis 1%, uas yog vim muaj kev lag luam vaj tse qeeb qeeb thiab tsoomfwv siv zog los txhim kho cov qauv kev lag luam49. Cov kws tshuaj ntsuam xyuas hais tias Is Nrias teb cov peev txheej hauv kev tsim kho vaj tse thiab kev nthuav dav tsheb yog cov tsav tsheb tseem ceeb, thaum Tuam Tshoj tsom mus rau "kev txhim kho zoo" los ntawm kev tsim khoom ntsuab thiab kev hloov pauv cov khoom siv.
Cov Khoom Qhia Txog:
• Cov Kav Dej ASTM A53Siv dav hauv kev thauj mus los roj, roj av, thiab dej vim lawv ruaj khov thiab ua raws li cov qauv thoob ntiaj teb.
• Cov Ntawv Hlau Corrugated: Muaj kev thov ntau rau kev tsim kho ru tsev thiab cladding, qhuas rau lawv lub neej ua haujlwm 20+ xyoo thiab kev siv nyiaj tsim nyog.
2. Cov Kev Txwv Carbon Hloov Kho Kev Lag Luam Dynamics
Cov lag luam hlau ntsib kev txwv tsis pub muaj "ton-steel carbon emission constraints" raws li Tuam Tshoj txoj "15th Five-Year Plan," thawb cov tuam txhab kom siv cov thev naus laus zis qis carbon. Cov kws tshaj lij hais tias kev teem nqi carbon thiab kev sau npe carbon footprint yuav tseem ceeb rau kev sib tw ua lag luam. Cov kev pib xws li kev ua hlau siv hydrogen thiab kev txhim kho kev ua haujlwm AI tau txais kev txhawb nqa, nrog cov neeg ua si loj xws li Baowu Steel thiab ArcelorMittal ua cov haujlwm sim.
Qhov Tseem Ceeb ntawm ASTM A53 Cov Kav Dej hauv Kev Lag Luam Hlau
Cov Ntawv Thov Dav Dav
Cov kav dej ASTM A53 qhia tau tias muaj ntau yam kev siv hauv ntau yam lag luam xws li kev tsim khoom, roj thiab roj av, kev muab dej, thiab cov kav dej. Lawv ua haujlwm ua cov kav dej rau cov kua dej xws li dej, roj, thiab roj av, nrog rau cov khoom siv tseem ceeb rau kev tsim cov thav duab, cov choj, thiab cov kav dej. Lub peev xwm ntawm ASTM A53 cov kav dej kom haum rau qhov ua tiav zoo heev, qib, thiab hom ua rau lawv tseem ceeb hauv kev ua kom tau raws li qhov xav tau ntawm ntau yam haujlwm.
Kev Ncaj Ncees thiab Kev Ntseeg Tau ntawm Cov Qauv
Cov kav dej ASTM A53 muaj npe nrov rau lawv cov qauv ruaj khov thiab kev ntseeg tau, ua rau lawv yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov tseem ceeb. Cov kav dej no raug sim thiab ua raws li cov kev cai nruj rau kev ua kom muaj zog, cov khoom siv kho tshuab, thiab cov qauv sib xyaw. Kev lees paub kev ntseeg tau yooj yim los ntawm ASTM A53 cov lus qhia yeeb nkab ua kom ntseeg tau tias muaj kev ntseeg tau thiab lub zog ntawm cov haujlwm ua haujlwm, ntxiv cov kev txhim kho zoo, thiab ua rau nws cov kev ua tau zoo thiab kev ntseeg tau ntawm cov kws kes duab vajtse, cov neeg ua haujlwm ntiav, thiab cov neeg koom nrog.
Kev Pab Txhawb Rau Kev Tsim Kho Vaj Tse
Cov kav dej ASTM A53 ua lub luag haujlwm tseem ceeb hauv kev tsim kho vaj tse los ntawm kev muab cov kev daws teeb meem ruaj khov thiab pheej yig rau kev xa cov kua dej thiab cov qauv txhawb nqa. Lawv siv dav hauv kev txhim kho hauv nroog, cov chaw lag luam, thiab cov haujlwm tsim kho vaj tse hauv nroog. Cov kav dej ASTM A53 pab txhawb rau kev tsim cov vaj tse ruaj khov thiab ruaj khov, ua rau muaj kev txhim kho cov tes hauj lwm thauj mus los, cov khoom siv hluav taws xob, cov tsev thiab lwm yam tseem ceeb ntxiv rau lub zej zog niaj hnub no, yog li txhim kho lub neej zoo thiab kev vam meej ntawm kev lag luam.
