Habka milixda-sodium sulfate ee Glauber waa hab dhaqameed leh tignoolajiyada qaan-gaadhka ah iyo ku-dhaqanka xooggan.Qalabka ceeriin waa barite iyo Glauber's milix, iyo wax soo saarka habkan waa sodium sulfide.Habka gaarka ah waa sida soo socota: Isku qas barite iyo budada dhuxusha si waafaqsan saamiga, ka dibna ka soo gal dabada dabka, la xiriir socodka hawada heerkulka sare ee ka soo horjeeda, oo samee falcelinta hoos u dhigista heerkulka sare ee 1100- 1500 ℃.Ilaha kulaylka ee looga baahan yahay falcelinta waa budada dhuxusha ama saliid culus.Gubashada si loogu diyaariyo barium sulfide clinker (oo loo yaqaan "dambas madow"), dheecaan, soo saarid iyo caddayn, si ay u fiirsashada tirada badan ee barium sulfide ay tahay 130-160 g/L.Isla mar ahaantaana, ku rid xaddi badan oo ah barium sulfate biyaha wasakhda ah (milaafi xal sodium sulfide) galay taangiga Nitrate, isticmaal mishiinka uumiga si aad u kululeyso in ka badan 40 ℃, billow qaswadayaasha, geli milixda Glauber ee taangiga, sii wad kulaylka ilaa 90 ℃, muunadu waxay isticmaashaa sodium sulfide si ay uga saarto kalsiyum Wixii wasakh ah magnesium, xoojinta tayada biyaha nitrate waxaa lagu xakameynayaa 1.2 ~ 1.22 g/cm3, ka dibna biyaha nitrate-ka waa la dahaaran yahay oo la dejiyey si loo isticmaalo.
Ka dib marka labada xal ee kor ku xusan la caddeeyo, dareeraha la caddeeyey ayaa la gelinayaa haanta isku-darka ah ee saamiga si loo fuliyo fal-celinta metathesis-ka, fal-celintu waxay gaartaa barta u dhiganta ama barium halide ayaa xoogaa xad dhaaf ah sida barta dhamaadka.Barium sulfate-ka diyaarsan iyo xalalka sodium sulfide ayaa la dhex geliyaa shaandhada si wada jir ah loogu kala saaro dareeraha adag, iyo dareeraha saafiga ah ee sodium sulfide wuxuu galaa qalabka soo kabashada ee uumiga iyo xoojinta.Keega barium-ka la sifeeyay waxaa lagu dhaqaa biyo oo waa la guray, waxaa lagu sii daayaa haanta barium slurry, oo lagu hagaajiyay pH 2-8 oo leh sulfuric acid ama fosfooraska acid, ka dib markii si buuxda loo sifeeyay, biyaha dheeraadka ah waxaa lagu cadaadiyaa saxan iyo saxan filter filter, iyo dabadeed keega barium waxa la dhex maraa mareen qaada Waxa loo qaadaa dhululubo qallajin si loo qalajiyo, ka dibna lagu burburiyo mishiinka Raymond oo la geeyaa weelka baakadaha, halkaas oo lagu baakadeeyo si loo helo badeecada barium sulphate degdega ah.
Sodium sulfide, oo ka mid ah wax soo saarka nidaamkan, ayaa si weyn looga isticmaalaa warshadaha sida farmashiyaha, waraaqaha samaynta, samaynta maqaarka, iyo midabada baaruudka.Gaar ahaan, horumarinta degdegga ah ee injineernimada cusub ee caagagga ah ee polyphenylene sulfide warshadaha ayaa gacan ka geysatay horumarinta warshadaha sodium sulfide.Warshadaha dheeha dhaqameedka, iyadoo ay ugu wacan tahay xidhitaanka xarumaha wax soo saarka shisheeye iyo balaadhinta joogtada ah ee shirkadaha dheeha dheesha ee Shiinaha, Shiinuhu waxa uu noqday soo saaraha ugu wayn iyo macaamiisha sodium sulfide, iyo dheeha sulfur ayaa sidoo kale noqday isticmaalayaasha ugu muhiimsan ee sodium sulfide.
2. Habka Barium sulfide-sulfuric acid
Habka barium sulfide-sulfuric acid dhab ahaantii wuxuu la mid yahay habka Glauber's salt-sodium sulfate, marka laga reebo in sulfuric acid loo isticmaalo halkii sodium sulfate, iyo wax soo saarkeedu waa hydrogen sulfide.Habka gaarka ah waa: isku darka barite iyo budada dhuxusha si waafaqsan saamiga, samaynta falcelinta heerkulka sare ee 1100 ~ 1500 ℃, diyaarinta barium sulfide clinker, leaching, sedimentation iyo caddayn, si ay u fiirsashada tirada badan ee barium sulfide waa 130 ～160 g/L.Ka dib, qiyaastii 30% sulfuric acid ayaa si tartiib ah loogu daraa brine barium ee la caddeeyey, falcelinta waxaa lagu sameeyaa haanta isku dhafka ah ee xiran.Dareen-celinta waxay gaartaa barta u dhiganta ama barium halide ayaa xoogaa xad dhaaf ah sida barta ugu dambeysa.
Barium sulfate-ka ay soo saarto fal-celinta ayaa la kululeeyaa si loo desulfurize, ka dibna barium sulfate waxaa lagu sii daayaa haanta barium slurry, pH waxaa lagu hagaajiyaa 6-8 alkali.Ka dib markii falcelinta si buuxda loo walaaqo, biyaha xad-dhaafka ah ayaa laga saarayaa saxan iyo saxan filter filter, ka dibna keega barium ayaa la dhex maraa Gaadhiga waxaa loo qaadaa dhululubada qalajinta si loo qalajiyo, ka dibna waxaa miiray mishiinka Raymond ilaa qashinka baakadaha. .Baakadaha ka dib, badeecada barium sulfate ee degdega ah ayaa la helayaa.Haydarojiin sulfide-ka ay dhaliso falcelinta waa la qalajiyey oo la nadiifiyaa si loo sii habeeyo.
Isticmaalka hydrogen sulfide sida walxo ceeriin ah, sulfide badan ayaa la soo saari karaa.Tusaale ahaan, agrochemical herbicide ethylthiocarbamate waxa uu ka samaysan yahay ethyl mercaptan, iyo ethyl mercaptan waxa laga sameeyay ethanol iyo hydrogen sulfide;iyo Octylthiocarbamate oo laga soo saaray octyl mercaptan waa cayayaan kale oo leh xulashada wanaagsan iyo sunta hoose.Methionine ee warshadaha quudinta waa wax lagu daro quudinta oo xoojisa quudinta oo ka dhigaysa dheelitirka asiidhyada amino.Waxaa lagu soo saaray methyl mercaptan oo ah walxo ceeriin ah.Caanaha lime waxaa loo isticmaalaa in lagu nuugo hydrogen sulfide oo lagu dhex daro xalka calcium cyanamide si loo soo saaro thiourea.Waa kiimiko badan oo shaqaynaysa, oo u dhaxaysa isku-darka alaabada dawooyinka (dhexdhexaadinta kiimikaad fiican) ilaa warshadaha dunta, dheeha iyo waraaqaha, laga bilaabo balaastigga iyo kimistariga resin ilaa warshadaynta birta iyo hydrometallurgy, thiourea waxay leedahay codsiyo balaadhan oo kaladuwan suuqyadan.
3. Habka Barium carbonate-sulfuric acid
Habka barium carbonate-sulfuric acid wuu ka duwan yahay labadii hore.Sababtoo ah xannibaadaha ilaalinta deegaanka, inta badan soosaarayaasha ma isticmaali karaan hababka yaraynta barista dubista heerkulka sare.Waxay kaliya u isticmaali karaan sunta tayada sare leh ama soo iibsatay barium carbonate warshadaynta.Qaado barium sulfate-ka degdega ah.Habka gaarka ah: Marka hore ku garaaca barium carbonate biyo, xakamaynta jajabka cufka adag ilaa 40%, ka dibna si tartiib ah ugu daraya xalka sulfuric acid ee ku saabsan 30% hoos walaaq joogto ah.Inta lagu jiro habka quudinta, waa in la ilaaliyaa wakhti kasta marka la walaaqayo., Si looga hortago ifafaale ee gasacadaha.Ka dib marka lagu daro walxaha, sii wad inaad walaaqdo 30 daqiiqo si aad si buuxda uga jawaabto barium carbonate, ka dibna shaandhayso, dhaq, slurry, buufin qallaji, iyo baakad alaabta.Sababtoo ah tiro badan oo ah xumbo kaarboon dioxide ayaa la soo saaraa inta lagu jiro falcelintan, dareeraha iyo falcelinta adag ee laba-waji ah ayaa lagu soo ururiyaa dusha sare ee xumbo leh meel gaar ah oo gaar ah, sidaas darteed qaybaha adag ee barium sulfate waa mid fiican, qaybta qaybinta cabbirku waa mid aad u yar, habka falcelintana waa la dedejiyay.
Barium sulfate-ka degdega ah ee uu soo saaro geeddi-socodkani wuxuu leeyahay caddaan sare, caddaanka qalabka dhismuhu wuxuu ka sarreeyaa 98, wasakh yar, content barium bilaash ah oo hooseeya, dhadhan sulfide ah oo aan lahayn hydrogen sulfide, si sahlan loo kala firdhiyo, qaybinta xajmiga cidhiidhiga ah, meel sare oo gaar ah, iyo sare daahan gloss ayaa la heli karaa.xuubabka.Inkasta oo qiimaha wax-soo-saarku uu sarreeyo, sababtoo ah alaabooyinka lagu soo saaro habkani waa kuwo tayo sare leh oo leh meelaynta suuqa sare, faa'iidadooda ayaa sidoo kale ah mid aad u badan.
Guud ahaan, hababka wax soo saarka barium sulfate ee Shiinaha waa saddexda kor ku xusan.Markaad dooranayso, waxaan ku dooran karnaa hadba baahidayada dhabta ah.Haddii aad u baahan tahay walxahan oo kale, waad nala soo xidhiidhi kartaa, waxaanu ku siin karnaa alaab aad u fiican, waxaanu sidoo kale ku siin karnaa jawaabo aqoon xirfadeed.
