Usoro nchịkọta nke ájá quartz na ịchịkọta ihe zuru ezu
Na nhọpụta nke ájá quartz dị ọcha na ájá quartz dị elu, ọ na-esiri ike izute ihe ndị a chọrọ nke usoro ntinye aka na-emekarị, karịsịa maka ihe nkiri ígwè oxide n'elu ala nke quartz ájá na ihe ndị na-adịghị ọcha nke ígwè na cracks.Iji meziwanye mma na mkpụrụ nke quartz ájá dị ọcha, jikọtara ya na njirimara nke quartz ájá na-adịghị edozi na acid na ntakịrị soluble na KOH ngwọta, usoro acid leaching aghọwo ụzọ dị mkpa iji na-emeso ájá quartz.
Ngwọta ịchịkọta ájá quartz bụ iji hydrochloric acid, sulfuric acid, oxalic acid ma ọ bụ hydrofluoric acid gwọọ ájá quartz iji gbazee ígwè.
Isi usoro nke quartz ájá pickling
M proportioning acid lotion
A ghaghị ime tọn ájá nke 7-9% oxalic acid, 1-3% hydrofluoric acid na 90% mmiri ngwakọta;Na-achọ 2-3.5 tọn mmiri, ọ bụrụ na a na-emegharị mmiri ahụ, mgbe ahụ, ọ bụ naanị 0.1 tọn mmiri dị mkpa iji hichaa otu ton nke ájá, na ọrụ nhicha ájá, ga-ebute ọtụtụ n'ime ájá elu;Ngwọta ịchịkọta ájá quartz bụ iji hydrochloric acid, sulfuric acid, oxalic acid ma ọ bụ hydrofluoric acid gwọọ ájá quartz iji gbazee ígwè.
Ngwakọta pickling
A na-agbanye ihe ngwọta nke pickling n'ime tankị pickling wee gbakwunye ya dịka oke nke ọdịnaya hydrochloric acid dịka 5% nke arọ ájá iji hụ na ájá quartz na-agbanye na ngwọta pickling na hydrochloric acid dị ihe dịka 5% nke mmiri. ájá arọ.
Ⅲ ájá quartz na-asacha acid
① Oge maka ájá quartz iji gbanye ihe ngwọta pickling bụ awa 3-5, mkpa a kapịrị ọnụ iji mụbaa ma ọ bụ belata oge ịrapara dị ka akpụkpọ anụ na-acha odo odo nke ájá quartz si dị, ma ọ bụ ngwọta pickling na quartz ájá nwere ike ịkpali maka oge. nke oge, na-esote iji ngwá ọrụ kpo oku na-ekpo ọkụ na ngwọta na okpomọkụ ụfọdụ, nwere ike ibelata oge pickling.
② Ojiji oxalic acid na akwụkwọ ndụ akwụkwọ ndụ alum dị ka mbenata ọgwụgwọ pickling n'ụlọnga nwere ike melite solubility nke ígwè, n'aka nke ya, mmiri, oxalic acid, akwụkwọ ndụ akwụkwọ ndụ alum dị ka nkezi nke ngwọta na a ụfọdụ okpomọkụ, quartz ájá na ngwọta dị ka dị. na akụkụ ụfọdụ nke ịgwakọta, na-akpali akpali, ọgwụgwọ maka nkeji ole na ole, a na-ehichapụ ihe ngwọta ahụ ma mesoo ya mgbe mgbake gasịrị.
③ Ọgwụgwọ Hydrofluoric acid: Mmetụta dị mma mgbe a na-etinye ọgwụgwọ hydrofluoric acid naanị, mana itinye uche dị elu.Mgbe ị na-ekekọrịta ya na sodium dithionite, enwere ike iji obere mkpokọta hydrofluoric acid mee ihe.
A na-agwakọta ụfọdụ ihe ngwọta nke hydrochloric acid na hydrofluoric acid n'ime slurry ájá quartz n'otu oge dịka oke nha;A pụkwara ịgwọ ya na ngwọta hydrochloric acid na mbụ, saa ya wee gwọọ ya na hydrofluoric acid, gwọọ ya na okpomọkụ dị elu maka awa 2-3, wee kpochaa ma kpochaa ya.
Mara:
Ọ bụrụ na a na-eji hydrofluoric acid mee ka acid soak quartz ájá, mmeghachi omume na-agbagwoju anya karị.Na mgbakwunye na mgbasa nke ígwè na mgbasa ozi acidic, HF nwekwara ike meghachi omume na quartz n'onwe ya iji gbaze SiO2 na silicates ndị ọzọ nke ụfọdụ ọkpụrụkpụ n'elu.
Otú ọ dị, nke a dị irè karị maka ihicha elu nke ájá quartz na ikpochapụ ígwè na mmetọ ndị ọzọ adịghị ọcha, ya mere hydrofluoric acid dị mma maka acid leaching nke quartz.Otú ọ dị, HF na-egbu egbu ma na-emebi emebi nke ukwuu, ya mere acid na-agbapụta mmiri mmiri chọrọ ọgwụgwọ pụrụ iche.
Iv Acid mgbake na deacidification
Jiri mmiri na-asachapụ ájá quartz nke acid na-asa 2-3 ugboro, wee wepụ ya na 0.05% -0.5% nke sodium hydroxide (caustic soda) ngwọta alkaline, na oge nkwụsịtụ bụ ihe dịka 30-60 nkeji, ma hụ na quartz niile. A na-ewepụ ájá n'ebe ahụ.Mgbe pH ruru alkaline, ị nwere ike hapụ lye wee sachaa ugboro 1-2 ruo mgbe pH na-anọpụ iche.
Ⅴ ájá quartz kpọrọ nkụ
A ga-ehichapụ ájá quartz na mmiri mgbe ọ kwụsịrị acid, mgbe ahụ, a ga-ehichapụ ájá quartz na ngwa ihicha.
