Kaboni Wotsika & Zachilengedwe: Za New Low Carbon Inorganic Gel Material
Kuchokera ku data ya carbon emission factor index, simenti wamba ya silicate imakhala ndi carbon emission factor ya 740 kg CO2eq/t;gypsum ili ndi 65 kg CO2eq/t;ndipo matabwa a MgO ali ndi 70 kg CO2eq/t.Poyerekeza, matabwa a MgO amachepetsa kwambiri mpweya wa kaboni panthawi yopanga.
Kuyerekeza kwa Kugwiritsa Ntchito Mphamvu Zopanga
Mapeto:
1.Kutentha kwamphamvu kwamafuta opangira matabwa a MgO ndi otsika kwambiri kuposa simenti ya calcium komanso pafupi ndi kupanga gypsum.
2.Kupanga zinthu za board za MgO sikumadya mphamvu zotentha.
3.Kugwiritsa ntchito mphamvu zonse za matabwa a MgO ndi pafupifupi theka la simenti ya kashiamu ndipo pafupifupi magawo awiri pa atatu aliwonse otsika kuposa a gypsum;mpweya wa CO2 umakhala pafupifupi theka la simenti ya calcareous ndi magawo awiri mwa atatu a gypsum.
Mpweya wa Carbon
5% ya mpweya wonse wa CO2 padziko lonse lapansi umachokera ku makampani a simenti, ndipo tani iliyonse ya clinker ya simenti yomwe imapangidwa imapanga matani 0.853 a mpweya wa CO2 mwachindunji ndi matani pafupifupi 0.006 a mpweya wa CO2 wosalunjika.Ma board a MgO, akayikidwa mumlengalenga, amatenga kuchuluka kwa CO2 kupanga magnesium carbonate, magnesium carbonate trihydrate, basic magnesium carbonate, ndi mankhwala ena a hydration.Ma board a MgO akasakanizidwa ndi madzi omanga, toni iliyonse ya simenti imatha kuyamwa matani 0,4 a carbon dioxide.Kulimbikitsa ndi kulimbikitsa kugwiritsa ntchito ma board a MgO kumatha kukhala kothandiza kuchepetsa mpweya wa carbon ndikukwaniritsa bwino zolinga zapawiri za carbon.
