Aluminium Hydroxide oo Fiican

Isticmaal: marka la soo saarayo aluminium hydroxide. Nuxurka: abuurka aluminium hydroxide waa la burburiyaa, ku qas xalka aluminate. Joojinta ka dhalata waxaa lagu kululeeyaa walaaqidda waxaana lagu daaweeyaa kaarboon laba ogsaydh. Kala soocida aluminium hydroxide iyo khamriga hooyada. Aluminium hydroxide waa la dhaqaa.

Ikhtiraacida waxay la xiriirtaa soo saarista aluminium hydroxide.

Hab lagu helo aluminium hydroxide oo fiican [1] kaas oo geeddi-socodka lagu sameeyo laba marxaladood. Marxaladda koowaad xalka aluminate waxaa lagu dhexdhexaadiyaa hydrochloric acid, ka dibna aluminium hydroxide-ka si fiican loo kala firdhiyey ayaa loo isticmaalaa sidii kala-goynta abuurka ee xalka aluminate ee aadka u buuxan marxaladda labaad.

Khasaaraha habkan waa kharashaadka sare ee ay keento dhexdhexaadinta alkali-ga caustic-ga ee aashitada, ururinta wasakhda ku jirta xalalka, iwm.

Habka ugu dhow ee ikhtiraacida hadda jirta waa hab [2] kaas oo loo isticmaalo aluminium hydroxide budada ah si loo soo saaro aluminium hydroxide.

Khasaaraha habkan waa xalka sare ee wintopo.

Ujeedada ikhtiraacida waa in la yareeyo kharashka halbeegga tamarta iyadoo la kordhinayo wax soo saarka aluminium hydroxide ee khafiifka ah.

Habka kaarboonaynta waxaa si weyn loogu isticmaalaa warshadaha aluminiumka ee ku shaqeeya sintering-ka. Isticmaalka kaarboonaynta waxay bixin kartaa hydroxide soo saar sare leh.

Cabbirka badarka ee aluminium hydroxide ee laga helo habka kaarboonaynta ayaa inta badan ku xiran heerkulka kaarboonaynta iyo halabuurka xalalka aluminate (ururinta alkali iyo alumina).

Habka la yaqaan (Biraha fudud. 1937, No. 10, S. 8-15) soo saarista aluminium hydroxide oo fiican iyadoo la adeegsanayo habka kaarboonaynta, oo ay ku jiraan habaynta xalalka kaarboon dioxide ultracracker aluminate (diirsanaanta 200 g/l) heerkul hooseeya (30)^{ku saabsan}C).

Inkasta oo habkani uu bixiyo hydroxide aluminium ah oo tayo sare leh, isticmaalkiisu waa mid aan macquul ahayn sababtoo ah dhibaatooyinka farsamo ee ka dhasha marxaladaha ugu dambeeya ee hawsha: Waaxda roobka iyo dhaqidda.

Si kastaba ha ahaatee, marka la isticmaalayo habka nizkokontsentrirovannye ee carbonization wuu ku guuldareystaa.

Cabbirka badarka ee aluminium hydroxide ee laga helo xaaladahan, oo lagu garto halabuurka aan isku mid ahayn iyo nuxurka sare ee walxaha qallafsan.

Ikhtiraacida waxaa ka mid ah habka loo soo saaro hydroxide aluminium ah oo fiican, oo ka kooban shiidi abuurka hydroxide aluminium, ku qas xalka aluminate, gabowga joojinta ka dhalatay iyadoo la walaaqayo, kala soocida hydroxide aluminium iyo khamriga hooyada iyo dhaqidda, ka hor inta aan la kala soocin hydroxide aluminium iyo dareeraha khamriga hooyada waxaa lagu daaweeyaa kaarboon dioxide.

Daraasaduhu waxay muujiyeen in marka la farsameynayo xalalka kaarboon laba ogsaydh ee aluminate oo ay ku jiraan xaddi badan oo adag, cabbirka walxaha ayaa ku dhawaad ​​isku mid ah.

Marka la samaynayo iniin la jajabiyey oo ku jirta xalka aluminate ee aadka u buuxa, oo la sii daayo joojinta ka dhalata iyadoo la walaaqayo waxay soo saartaa xaddi badan oo ah hydroxide aluminium ah oo aad u kala firirsan. Si kastaba ha ahaatee, wax soo saarka aluminium hydroxide oo fiican iyada oo aan la isticmaalin habayn dheeraad ah oo joojinta ah waa mid hooseeya waxayna ku xiran tahay isku-darka alkali caustic ah ee xalka: xoojinta alkali oo sarreysa, wax soo saarka ayaa hooseeya.

Marka la farsameynayo kaarboon laba ogsaydh, joojinta bilowga ah waxaa bixiya wax soo saarka aluminium hydroxide waa isku mid sida habka loo farsameeyo joojinta ka dib soo-gaadhista hordhaca ah, si kastaba ha ahaatee, si weyn ayuu u kordhiyaa cabbirka walxaha aluminium hydroxide.

Habka waxaa lagu hirgelin karaa iyadoo la isticmaalayo qalabka jira.

Habka ugu habboon ee dhirta alumina ku salaysan tiknoolajiyada spechitelnoj.

Isbarbardhigga xogta laga helay tijaabooyin badan ayaa soo jeedinaya in habka loo farsameeyo slurry-ka qoyaanka ee la helo ka dib markii la soo bandhigo isku darka xalka aluminate iyo abuurka la jarjaray, kaarboon laba ogsaydh ayaa u oggolaanaya inuu helo hydroxide aluminium ah oo fiican oo hubiyo wax soo saar sare.

PRI me R 1. 0.02 kg oo aluminium hydroxide ah oo leh celcelis ahaan cabbirkiisu yahay 2.8 μm ayaa lagu qasay 1 litir oo xal aluminate ah oo ka kooban, g/l: Na₂CMOS 100,8;₂O₃107,4.

Joojinta ka dhalatay waxaa la ansixiyay 60 daqiiqo^{ku saabsan}Iyadoo in ka badan 10 saacadood la isticmaalay, hydroxide aluminium ah oo fiican ayaa ahaa 40,4, celceliska cabbirka walxaha ku jira dhoobada oo ah 3.6 μm. Halabuurka wejiga dareeraha ah ee joojinta, isku darka Noi, oo ka kooban qiyaastii 12. CO2₂Waqtiga farsamaynta oo ah 6 saacadood ilaa inta harsan ee sodium oksaydh ee xalka ka dib marka la daaweeyo 5.6 g/L.

Cabbirka celceliska walxaha ku jira ciidda ka dib daaweynta waa 4.8 μm. Wax soo saarka aluminium hydroxide 102,5.

PRI mme R 2. 0.02 kg oo aluminium hydroxide ah oo cabirkiisu yahay celcelis ahaan 2.8 μm ayaa lagu qasay 1 litir oo xal aluminate ah isla markiiba (iyada oo aan la soo bandhigin) waxaa lagu daaweeyay kaarboon laba ogsaydh. Muddada daaweynta iyo fiirsashada CO2₂isku darka gaaska oo la mid ah tusaalaha 1aad.

Wax soo saarka aluminium hydroxide wuxuu ahaa 103,1, celceliska cabbirka walxaha ku jira dhoobada oo ah 30.4 μm.

Sidaa darteed, hirgelinta taxanaha hawlgallada kor ku xusan: isku darka xalka aluminate oo leh soosaarka abuurka la jajabiyey, joojinta ka dhalatay, slurry kaarboon ka hor inta aan la kala saarin aluminium hydroxide waxay bixin kartaa hydroxide aluminium ah oo tayo sare leh.

HABKA SOO SAARKA FIICAN ALUMINUM HYDROXIDE, oo ka kooban shiididda abuurka hydroxide-ka aluminiumka, ku qasidda xalka aluminate-ka, da'da ka saarista joojinta ka dhalatay iyadoo la walaaqayo, kala soocidda hydroxide-ka aluminiumka iyo khamriga hooyada iyo dhaqidda,
