Mfundo ya muffle ng’anjo calcination
Mfundo ya muffle ng’anjo calcination
Muffle ng’anjo calcination: kutentha mankhwala mu mpweya kapena inert mpweya pa kutentha kwina, wotchedwa calcination kapena Kuwotcha.
Zosintha zazikulu zakuthupi ndi zamankhwala munjira yowerengera ng’anjo ya muffle ndi:
(1) Kuwola kwamafuta: chotsani madzi omangidwa ndi mankhwala, CO2, NOx ndi zonyansa zina zosasunthika. Pakutentha kwambiri, ma oxides amathanso kukhala olimba-gawo kuti apange gawo logwira ntchito;
(2) Recrystallization: Mawonekedwe ena a kristalo, kukula kwa kristalo, kapangidwe ka pore ndi malo enieni angapezeke;
(3) Ma crystallites amapangidwa bwino kuti apititse patsogolo mphamvu zamakina.
Mfundo zazikulu zimene zimakhudza calcination ndondomeko: calcination kutentha, mpweya gawo zikuchokera, matenthedwe bata pawiri, etc. Choncho, malinga ndi matenthedwe bata zosiyanasiyana mankhwala (monga carbonate, okusayidi, hydroxide-sulfide, oxyacid mchere, etc. ), kutentha kwa calcination ndi kapangidwe ka gasi kumatha kuyendetsedwa kuti musankhe kusintha kukhazikika kwamafuta azinthu zina. Mapangidwe kapena mawonekedwe a kristalo amasintha, kenako amathandizidwa ndi njira zofananira, amatha kukwaniritsa cholinga chochotsa zonyansa ndikulekanitsa ndikulemeretsa magulu othandiza.
