Ụkpụrụ nke muffle oven calcination

Igwe ọkụ muffle calcination: ọgwụgwọ okpomọkụ na ikuku ma ọ bụ gas inert n’otu okpomọkụ, nke a na-akpọ calcination ma ọ bụ nsị.

Mgbanwe nke anụ ahụ na kemịkalụ bụ isi na usoro ịgbatị ọkụ muffle bụ:

(1) Thermal ire ere: wepụ mmiri kemịkal, CO2, NOx na adịghị ike ndị ọzọ. N’ebe okpomọkụ dị elu, oxides nwekwara ike ịnweta mmeghachi omume siri ike na-eme ka ọnọdụ ngwakọta na-arụ ọrụ;

(2) Recrystalization: Enwere ike nweta ụfọdụ udi kristal, nha kristal, ihe owuwu pore na elu dị iche iche;

(3) The crystallites na-nke ọma sintered ka mma n’ibu ike.

Ihe ndị bụ isi nke na-emetụta usoro nhazi: okpomọkụ calcination, ihe mejupụtara gas gas, nkwụsi ike nke okpomọkụ nke ogige, wdg. Ya mere, dị ka nkwụsi ike nke okpomọkụ dị iche iche (dịka carbonate, oxide, hydroxide-sulfide, oxide salt, wdg). ), enwere ike ịchịkwa okpomọkụ calcination na ihe mejupụtara gas ka ọ gbanwee nkwụsi ike nke okpomọkụ nke ụfọdụ ogige. Ngwakọta ma ọ bụ kristal na-agbanwe agbanwe, wee mesoo ya na usoro kwekọrọ, nwere ike nweta ebumnuche nke iwepụ adịghị ọcha na ikewapụ na ịba ọgaranya dị iche iche bara uru.
