Cov hlau tsis xeb - rov ua dua tshiab thiab ruaj khov

Cov hlau tsis xeb uas siv tau dua tshiab thiab ruaj khov

Txij li thaum nws thawj zaug qhia tawm xyoo 1915, cov hlau tsis xeb tau raug xaiv dav dav rau kev siv hauv ntau yam lag luam vim nws cov khoom siv kho tshuab thiab xeb zoo heev. Tam sim no, raws li ntau thiab ntau qhov kev tsom mus rau kev xaiv cov khoom siv ruaj khov, cov hlau tsis xeb tau txais kev lees paub tseem ceeb vim nws cov khoom zoo rau ib puag ncig. Cov hlau tsis xeb yog 100% rov ua dua tshiab thiab feem ntau ua tau raws li qhov yuav tsum tau ua neej ntawm ib qhov project nrog cov nqi rov qab zoo heev. Tsis tas li ntawd, nws yog ib qho tseem ceeb kom paub tias thaum feem ntau muaj kev xaiv nyuaj ntawm kev siv cov kev daws teeb meem ntsuab thiab kev siv cov kev daws teeb meem pheej yig, cov kev daws teeb meem hlau tsis xeb feem ntau muab cov khoom kim heev ntawm ob qho tib si.

Cov hlau tsis xeb uas siv tau dua tshiab

Cov hlau tsis xeb yog 100% rov ua dua tshiab thiab yuav tsis lwj. Cov txheej txheem rau kev rov ua dua cov hlau tsis xeb yog tib yam li kev tsim nws. Tsis tas li ntawd, cov hlau tsis xeb yog ua los ntawm ntau yam khoom siv raw, suav nrog hlau, nickel, chromium thiab molybdenum, thiab cov ntaub ntawv no muaj kev thov siab. Tag nrho cov yam no ua ke ua rau kev rov ua dua cov hlau tsis xeb pheej yig heev thiab yog li ua rau muaj kev rov ua dua tshiab siab heev. Kev tshawb fawb tsis ntev los no los ntawm International Stainless Steel Forum (ISSF) qhia tau hais tias kwv yees li 92% ntawm cov hlau tsis xeb siv hauv kev tsim kho, kev tsim kho thiab kev siv thoob ntiaj teb raug rov qab thiab rov ua dua tshiab thaum kawg ntawm kev pabcuam. [1]

Xyoo 2002, Lub Rooj Sab Laj Thoob Ntiaj Teb Txog Cov Hlau Stainless Steel tau kwv yees tias cov ntsiab lus rov ua dua tshiab ntawm cov hlau stainless yog li 60%. Hauv qee kis, qhov no siab dua. Kev Lag Luam Hlau Tshwj Xeeb ntawm North America (SSINA) hais tias 300 series stainless hlau tsim tawm hauv North America muaj cov ntsiab lus rov ua dua tshiab tom qab siv ntawm 75% txog 85%. [2] Txawm hais tias cov lej no zoo heev, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias lawv tsis yog qhov laj thawj rau qhov siab dua. Cov hlau stainless feem ntau muaj lub neej ntev hauv feem ntau daim ntawv thov. Tsis tas li ntawd, qhov kev thov rau cov hlau stainless yog siab dua niaj hnub no dua li yav dhau los. Yog li ntawd, txawm hais tias muaj kev rov ua dua tshiab ntawm cov hlau stainless, lub neej tam sim no ntawm cov hlau stainless hauv cov kav dej tsis txaus los ua kom tau raws li cov kev xav tau tsim khoom niaj hnub no. Qhov no yog ib lo lus nug zoo heev.

Cov hlau tsis xeb uas ruaj khov

Ntxiv rau qhov muaj cov ntaub ntawv pov thawj ntawm kev siv rov qab tau zoo thiab cov nqi rov qab thaum kawg ntawm lub neej, cov hlau tsis xeb ua tau raws li lwm qhov tseem ceeb rau cov ntaub ntawv ruaj khov. Yog tias cov hlau tsis xeb tsim nyog raug xaiv los phim cov xwm txheej corrosive ntawm ib puag ncig, cov hlau tsis xeb feem ntau tuaj yeem ua tau raws li qhov xav tau ntawm lub neej ntawm qhov project. Thaum lwm cov ntaub ntawv yuav poob lawv cov txiaj ntsig dhau sijhawm, cov hlau tsis xeb tuaj yeem tswj tau kev ua haujlwm thiab tsos rau lub sijhawm ntev. Lub Tsev Empire State (1931) yog ib qho piv txwv zoo ntawm kev ua tau zoo mus sij hawm ntev thiab kev siv nyiaj ntawm kev tsim kho hlau tsis xeb. Lub tsev tau ntsib kev ua qias tuaj ntau hauv feem ntau, nrog rau cov txiaj ntsig ntxuav tsawg heev, tab sis cov hlau tsis xeb tseem suav tias nyob rau hauv qhov zoo [iii].

Cov hlau tsis xeb - kev xaiv ruaj khov thiab pheej yig

Qhov zoo siab tshwj xeeb tshaj yog tias kev xav txog qee yam uas ua rau cov hlau tsis xeb yog qhov kev xaiv ib puag ncig kuj tuaj yeem ua rau nws yog qhov kev xaiv zoo heev, tshwj xeeb tshaj yog thaum xav txog tus nqi tas mus li ntawm qhov project. Raws li tau hais ua ntej lawm, cov qauv hlau tsis xeb feem ntau tuaj yeem ntev lub neej ntawm ib qhov project ntev npaum li cov hlau tsis xeb tsim nyog raug xaiv los ua kom tau raws li cov xwm txheej xeb ntawm ib daim ntawv thov tshwj xeeb. Qhov no, ua rau tus nqi ntawm kev siv ntau dua piv rau cov ntaub ntawv uas tsis muaj lub neej ntev. Tsis tas li ntawd, cov hlau tsis xeb rau cov haujlwm kev lag luam tuaj yeem txo cov nqi kho thiab tshuaj xyuas lub neej thaum txo cov nqi tsim khoom. Hauv cov haujlwm tsim kho, cov hlau tsis xeb zoo tuaj yeem tiv taus qee qhov chaw ib puag ncig hnyav thiab tseem khaws nws qhov zoo nkauj dhau sijhawm. Qhov no tuaj yeem txo cov nqi pleev xim thiab ntxuav tas mus li uas yuav tsum tau piv rau lwm cov ntaub ntawv. Tsis tas li ntawd, kev siv cov hlau tsis xeb pab txhawb rau daim ntawv pov thawj LEED thiab pab ua kom tus nqi ntawm qhov project nce ntxiv. Thaum kawg, thaum kawg ntawm lub neej ntawm qhov project, cov hlau tsis xeb seem muaj tus nqi pov tseg siab.
