Ka’idar muffle tanderun calcination

Muffle furnace calcination: maganin zafi a cikin iska ko iskar gas a wani zafin jiki, wanda ake kira calcination ko gasasshen

Babban canje-canjen jiki da sinadarai a cikin tsarin ƙididdige tanderun wuta sune:

(1) Bazuwar thermal: cire ruwa da aka ɗaure da sinadarai, CO2, NOx da sauran ƙazantattun ƙazanta. A yanayin zafi mafi girma, oxides kuma na iya yin tasiri mai ƙarfi-lokaci don samar da yanayin fili mai aiki;

(2) Recrystallization: Ana iya samun wani nau’in crystal, girman crystal, tsarin pore da takamaiman wuri;

(3) Ƙaƙƙarfan kristal an yi su da kyau don inganta ƙarfin injiniya.

Babban abubuwan da ke shafar tsarin ƙididdiga: yawan zafin jiki na calcination, tsarin lokaci na gas, kwanciyar hankali na thermal na fili, da dai sauransu. Saboda haka, bisa ga kwanciyar hankali na thermal na daban-daban mahadi (kamar carbonate, oxide, hydroxide-sulfide, oxide gishiri, da dai sauransu). ), ana iya sarrafa yanayin zafin ƙima da abun da ke ciki na gas don zaɓin canza yanayin kwanciyar hankali na wasu mahadi. Ƙirƙiri ko nau’in crystal yana canzawa, sannan kuma a bi da su tare da hanyoyi masu dacewa, na iya cimma manufar kawar da ƙazanta da rarrabawa da haɓaka ƙungiyoyi masu amfani.
