Ájá quartz a sachara n'ihi acid
Usoro nkọwa zuru ezu nke ịchacha ájá quartz na ịchacha ya
N'ịhọrọ ájá quartz a sachapụrụ acha na ájá quartz dị ọcha nke ukwuu, ọ na-esiri ike imezu ihe achọrọ n'ụzọ ndị a na-ejikarị eme ihe, karịsịa maka ihe nkiri iron oxide dị n'elu ájá quartz na ihe ndị na-adịghị ọcha ígwè dị na mgbawa. Iji melite mma na mmepụta nke nhicha ájá quartz, yana njirimara nke ájá quartz nke na-anaghị agbaze na acid na nke na-agbaze ntakịrị na ngwọta KOH, usoro ịchacha acid aghọwo ụzọ dị mkpa iji gwọọ ájá quartz.
Ọgwụgwọ ịkpụcha ájá quartz bụ iji hydrochloric acid, sulfuric acid, oxalic acid ma ọ bụ hydrofluoric acid gwọọ ájá quartz iji gbazee ígwè.

① Oge ájá quartz ga-amịkọrọ mmiri mmiri nke a na-akpọ "plain" bụkarị awa 3-5, mkpa kpọmkwem nke ịbawanye ma ọ bụ ibelata oge mmiri mmiri dịka akpụkpọ ahụ odo nke ájá quartz si dị, ma ọ bụ mmiri mmiri na ájá quartz nwere ike ịkpalite ruo oge ụfọdụ, wee jiri ngwa ọkụ kpoo mmiri ọkụ ruo okpomọkụ ụfọdụ, nke nwere ike ibelata oge ịcha ihe.
② Ojiji nke oxalic acid na akwụkwọ ndụ akwụkwọ ndụ alum dị ka ọgwụgwọ mmịpụta ihe na-ebelata nwere ike ime ka ígwè sie ike ịgbaze, n'aka nke ya, mmiri, oxalic acid, akwụkwọ ndụ akwụkwọ ndụ alum dịka oke nke ngwọta ahụ si dị na okpomọkụ ụfọdụ, ájá quartz na ngwọta dịka oke nke ngwakọta, ịkpalite, ọgwụgwọ maka nkeji ole na ole, a na-asachapụ ma gwọọ ya mgbe ọ gbakechara.
③ Ọgwụgwọ Hydrofluoric acid: Mmetụta ya dị mma mgbe a na-etinye ọgwụgwọ hydrofluoric acid naanị ya, mana ntinye ahụ dị elu. Mgbe a na-ejikọta ya na sodium dithionite, enwere ike iji obere ntinye nke hydrofluoric acid.
E tinyere otu njupụta nke hydrochloric acid na hydrofluoric acid n'ime quartz sand slurry n'otu oge dịka oke ya si dị; Enwere ike iji mmiri hydrochloric acid gwọọ ya na mbụ, saa ya wee jiri hydrofluoric acid gwọọ ya, gwọọ ya na oke okpomọkụ ruo awa 2-3, wee kpochaa ya ma hichaa ya.
Rịba ama:
Ọ bụrụ na ejiri hydrofluoric acid mee ka ájá quartz mikpuo acid, mmeghachi omume ahụ ga-esikwu ike. Na mgbakwunye na mgbasa nke ígwè na acidic media, HF nwekwara ike imeghachi omume na quartz n'onwe ya iji gbazee SiO2 na silicates ndị ọzọ nwere oke ọkpụrụkpụ n'elu.
Agbanyeghị, nke a dị irè karịa maka ihicha elu ájá quartz na iwepụ ígwè na mmetọ ndị ọzọ na-adịghị ọcha, yabụ hydrofluoric acid dị mma maka ịcha acid nke quartz. Agbanyeghị, HF na-egbu egbu ma na-emebi emebi nke ukwuu, yabụ mmiri mkpofu nke na-ewepụ acid chọrọ ọgwụgwọ pụrụ iche.
Mweghachi na mbelata asịd na acid
Sachaa ájá quartz nke a sachara na acid ugboro abụọ-3, wee jiri mmiri sachaa ya na 0.05%-0.5% nke sodium hydroxide (caustic soda) alkaline solution, oge neutralization ahụ ga-ewe ihe dị ka nkeji iri atọ-60, hụkwa na e tinyere ájá quartz niile n'ọnọdụ ya. Mgbe pH ahụ ruru alkaline, ị nwere ike ịhapụ lye ma sachaa ya ugboro 1-2 ruo mgbe pH ahụ ga-adị na-anọpụ iche.
Ⅴ Ájá quartz akọrọ
A ga-ewepụ ájá quartz ahụ na mmiri mgbe a kwụsịrị acid ahụ, wee kpọọ ájá quartz ahụ nkụ na ngwa nkụ.
