Tsawg Carbon & Ib puag ncig: Ua rau Cov Khoom Siv Hluav Taws Xob Tsis Zoo Tshiab Tshiab
Los ntawm cov ntaub ntawv qhia txog cov pa roj carbon emission index, zoo tib yam silicate cement muaj cov pa roj carbon emission ntawm 740 kg CO2eq / t;gypsum muaj 65 kg CO2eq / t;thiab MgO boards muaj 70 kg CO2eq / t.Piv txwv li, MgO boards txo qis carbon emissions thaum lub sij hawm tsim khoom.
Kev sib piv kev siv hluav taws xob ntau lawm
Cov lus xaus:
1.Qhov thermal zog noj ntawm cov khoom siv raw ntawm MgO boards yog qis dua li ntawm calcium cement thiab ze rau ntawm gypsum ntau lawm.
2.Qhov kev tsim khoom ntawm MgO board cov khoom pib siv tsis muaj cua sov.
3.Lub zog tag nrho ntawm MgO boards yog li ib nrab ntawm cov calcium cement thiab li ob feem peb qis dua li ntawm gypsum;CO2 emission yog ib nrab ntawm calcareous cement thiab ob feem peb ntawm gypsum.
Cov pa roj carbon absorption
5% ntawm lub ntiaj teb tag nrho CO2 emissions yog los ntawm cov tsoos cement kev lag luam, thiab txhua tuj ntawm cement clinker tsim generates 0.853 tons ntawm ncaj qha CO2 emissions thiab txog 0.006 tons ntawm indirect CO2 emissions.MgO cov laug cam, thaum muab tso rau hauv huab cua, yuav nqus tau ntau ntawm CO2 los tsim magnesium carbonate, magnesium carbonate trihydrate, magnesium carbonate, thiab lwm yam hydration compounds.Thaum MgO boards tov nrog dej rau kev tsim kho, txhua tuj ntawm cov cement tuaj yeem nqus tau 0.4 tons ntawm carbon dioxide.Kev txhawb nqa thiab txhawb nqa daim ntawv thov ntawm MgO boards tuaj yeem ua rau cov pa roj carbon tsawg thiab kev ua tiav zoo dua ntawm ob lub hom phiaj carbon.
