Kaona Haʻahaʻa & Nā Pono Hana Kaiapuni o nā Papa MgO

Nā hopena:

1. ʻOi aku ka haʻahaʻa o ka ikehu wela o ka hana ʻana o nā papa MgO ma mua o ka sima calcium a kokoke i ka hana gypsum.
2. ʻAʻole pau ka ikehu wela i ka hana ʻana o nā huahana papa MgO.
3. ʻO ka nui o ka ikehu o nā papa MgO ma kahi o ka hapalua o ka sima calcium a ma kahi o ʻelua hapakolu haʻahaʻa ma mua o ka gypsum;ʻO ka hoʻokuʻu ʻana o CO2 ma kahi o ka hapalua o ka sima calcareous a ʻelua hapakolu o ka gypsum.

Hoʻopiʻi kalapona

ʻO 5% o ka nui o ka hoʻokuʻu CO2 o ka honua mai ka ʻoihana sima kuʻuna, a ʻo kēlā me kēia tona o ka clinker sima i hana ʻia he 0.853 tons o ka hoʻokuʻu CO2 pololei a ma kahi o 0.006 tons o ka hoʻokuʻu ʻole ʻia CO2.ʻO nā papa MgO, ke kau ʻia i ka lewa, e hoʻomoʻa i ka nui o CO2 e hana i ka magnesium carbonate, magnesium carbonate trihydrate, magnesium carbonate kumu, a me nā mea hoʻohuihui wai.Ke hui ʻia nā papa MgO me ka wai no ke kūkulu ʻana, hiki i kēlā me kēia tona o ka sima ke komo i 0.4 mau tona kalapona.ʻO ka paipai ʻana a me ka hoʻoikaika ʻana i ka hoʻohana ʻana i nā papa MgO hiki ke kōkua i ka hōʻemi kalapona a me ka hoʻokō maikaʻi ʻana o nā pahu kalapona ʻelua.
