Habka qaadidda ciidda Quartz oo faahfaahsan
Xulashada ciidda quartz ee la nadiifiyey iyo ciidda quartz ee nadiifka ah, way adagtahay in la buuxiyo shuruudaha hababka ka faa'iidaysiga caadiga ah, gaar ahaan filimka birta ah ee dusha sare ee carrada quartz iyo wasakhda birta ee dildilaaca.Si loo hagaajiyo tayada iyo wax-soo-saarka nadiifinta ciidda quartz, oo ay weheliso sifooyinka ciidda quartz ee aan lagu milmi karin aashitada iyo wax yar oo ku milma xalalka KOH, habka leaching acid wuxuu noqday hab lagama maarmaan ah oo lagu daweeyo ciidda quartz.
Daawaynta ciidda quartz waa in lagu daweeyo ciid quartz leh hydrochloric acid, sulfuric acid, oxalic acid ama hydrofluoric acid si loo milo birta.
Habka aasaasiga ah ee qashin quartz ciid
Waxaan u dhigma kareemka aashitada
Tan oo ciid ah ayaa loo baahan yahay in laga sameeyo 7-9% oxalic acid, 1-3% hydrofluoric acid iyo 90% isku dhafka biyaha;Waxay u baahan tahay 2-3.5 tan oo biyo ah, haddii biyaha dib loo warshadeeyo, markaa kaliya 0.1 tan oo biyo ah ayaa loo baahan yahay si loo nadiifiyo tan oo ciid ah, hawlgalka nadiifinta ciidda, ayaa si lama filaan ah u keenaya ciidda inteeda badan;Daawaynta ciidda quartz waa in lagu daweeyo ciid quartz leh hydrochloric acid, sulfuric acid, oxalic acid ama hydrofluoric acid si loo milo birta.
Ⅱ Isku darka pickling
Xalka qajaarka ayaa lagu duraa haanta wax lagu qaado waxaana lagu daraa iyadoo loo eegayo saamiga maadada hydrochloric acid sida qiyaastii 5% miisaanka ciidda si loo hubiyo in ciidda quartz lagu qooyay xalalka qajaarka iyo waxa ku jira hydrochloric acid waa qiyaastii 5% miisaanka ciidda.
Ⅲ Ciid quartz aysiidh-dhaqtay
① Waqtiga ciidda quartz si loo qooyo xalka pickling guud ahaan waa 3-5 saacadood, baahida gaarka ah ee kordhinta ama hoos u dhigista wakhtiga qooynta iyadoo loo eegayo maqaarka jaalaha ah ee ciidda quartz, ama xalka pickling iyo ciid quartz waa la walaaqi karaa muddo. waqtiga, oo ay ku xigto isticmaalka qalabka kuleyliyaha si loo kululeeyo xalka heerkul gaar ah, waxay yareyn kartaa wakhtiga pickling.
② Isticmaalka oxalic acid iyo alum cagaarka ah sida hoos u dhigista wakiilka pickling daaweynta waxay hagaajin kartaa milanka birta, markeeda, biyaha, oxalic acid, alum cagaaran si waafaqsan saamiga xalku heerkulka gaar ah, quartz ciid iyo xal si waafaqsan. oo leh qayb gaar ah oo isku dhafan, walaaqaya, daaweyn dhowr daqiiqo ah, xalka waa la sifeeyaa oo la daaweeyaa ka dib soo kabashada.
③ Daawaynta aashitada Hydrofluoric: Saamayntu way wanaagsan tahay marka daawaynta aashitada hydrofluoric kaligeed la mariyo, laakiin xooga saaridu way ka sarraysaa.Marka lala wadaago sodium dithionite, uruurinta hoose ee hydrofluoric acid waa la isticmaali karaa.
Qayb gaar ah oo ah hydrochloric acid iyo hydrofluoric acid ayaa lagu qasi jiray qulqulka ciidda quartz isku mar iyadoo loo eegayo saamiga;Waxa kale oo lagu daweyn karaa marka hore xal hydrochloric acid, la dhaqo ka dibna lagu daaweeyaa hydrofluoric acid, lagu daaweeyaa heerkul sarreeya 2-3 saacadood, ka dibna la sifeeyo oo la nadiifiyo.
Fiiro gaar ah:
Haddii hydrofluoric acid loo isticmaalo in lagu qooyo ciidda quartz, falcelintu aad ayay u adag tahay.Marka lagu daro kala dirida birta ee warbaahinta acidic, HF waxay sidoo kale ka falcelin kartaa quartz lafteeda si ay u milmaan SiO2 iyo silicates kale oo dhumucdiisuna tahay dusha sare.
Si kastaba ha ahaatee, tani waxay waxtar badan u leedahay nadiifinta dusha sare ee ciidda quartz iyo baabi'inta birta iyo wasakhowga kale ee wasakhaysan, sidaas darteed hydrofluoric acid waxay u fiican tahay dheecaanka ashitada quartz.Si kastaba ha ahaatee, HF waa sun oo aad u daxalaysa, sidaas darteed biyaha wasakhda ah ee aashitada ka daadiya waxay u baahan yihiin daaweyn gaar ah.
IV Acid soo kabashada iyo deaqista
Ku raaci ciidda quartz-ka ee aysiidh-dhaqtay biyo 2-3 jeer, ka dibna dhexdhexaadin 0.05% -0.5% ee sodium hydroxide (caustic soda) xalalka alkaline, iyo wakhtiga dhexdhexaadinta waa qiyaastii 30-60 daqiiqo, oo hubi in dhammaan quartz ciid ayaa meesha ka saaraysa.Marka pH gaadho alkaline, waxaad sii dayn kartaa lye oo raaci kartaa 1-2 jeer ilaa pH ay noqoto dhexdhexaad.
Ⅴ Ciid quartz qalalan
Ciidda quartz-ka waa in laga daadiyaa biyaha ka dib marka ay aashitada ka baxdo, ka dibna ciidda quartz waa in lagu qallajiyaa qalabka qalajinta.
Ⅵ baadhista, xulashada midabka iyo baakaynta, iwm.
Kor ku xusan waa habka aasaasiga ah ee pickling ciidda quartz iyo geeddi-socodka daaweynta leaching, quartz ciidda ciidda leeyahay qaybinta xad ballaadhan ee dalkeenna, sidaas darteed waxaa jira kala duwanaansho ee dabeecadda ciidda quartz, in nadiifinta ciidda quartz sidoo kale u baahan tahay in dhibaatooyin gaar ah oo gaar ah. falanqaynta, horumariyo habka sifaynta ciidda quartz ku habboon.
