Isticmaalka: soo saarista aluminium hydroxide. Uumiga aluminium hydroxide ee la shiiday ee la shiiday 120 ilaa 250°C, isku darka profile-ka ayaa isku ururaya oo dhumuc weynaadaya si loo helo biyo-xidheen leh walxo adag oo ah 50 ilaa 300 g/l iyo sodium oxide marxaladda dareeraha ah ee 0.05 - 5 g/l. Suspension-ka biyaha ayaa lagu daraa xal aluminate oo aad u buuxa, iyadoo la marinayo suspension-ka la helay iyadoo la walaaqayo, iyadoo la kala soocayo aluminium hydroxide-ka kala go'ay iyo khamriga hooyada oo la dhaqay. 1 Cp f-crystals, 1 Il., jadwalka 1.

Ikhtiraacidani waxay la xiriirtaa soo saarista aluminium hydroxide, gaar ahaan soo saarista aluminium hydroxide oo fiican oo laga helo xalalka biyaha ee sodium aluminate.

Hab lagu helo aluminium hydroxide oo fiican [1] kaas oo habka lagu sameeyo laba marxaladood. Marxaladda koowaad xalka aluminate waxaa lagu dhexdhexaadiyaa hydrochloric acid, aluminium hydroxide-ka ka dhashana waxaa loo isticmaalaa sidii kala-goynta abuurka ee kala-goynta xalka aluminate ee supersaturated marxaladda labaad. Natiijo ahaan, aluminium hydroxide oo leh qaab-dhismeedka hydrargillite, kaas oo loo isticmaalo ujeedooyin kala duwan, tusaale ahaan prigotovit natiijo ka dhalatay dhexdhexaadinta xalka aluminate alkali caustic. Aluminium hydroxide-ka ka dhasha waxaa lagu gartaa kala-goynta sare iyo qaab-dhismeedka aan qaab-dhismeedka lahayn ee walxaha, taasoo soo jeedinaysa firfircoonidiisa abuurka ee kala-goynta xalalka aluminate.

Si kastaba ha ahaatee, habkan diyaarinta abuurka waxaa suurtogal ah oo keliya marka la isticmaalayo xalalka aluminate ee si gaar ah loo diyaariyey, oo aan lahayn wasakh. Haddii kale, hydroxide-ka aluminiumka ah ee ka dhasha ayaa nuugaya wasakhda ka soo baxda xalka, dhaqdhaqaaqa abuurkana wuu yaraanayaa. Intaa waxaa dheer, hirgelinta habkan sababtoo ah xawaaraha degitaanka oo hooseeya iyo shaandhaynta abuurka hydroxide-ka aluminiumka ah ayaa lagu bixiyaa marxaladda labaad qaab hakin ah. Xaaladdan oo kale, dhammaantood oo lagu sameeyay marxaladda koowaad ee milixda ayaa ku dhacaya marxaladda labaad, iyagoo wasakhaynaya badeecada aasaasiga ah oo ku wareegaya dhinaca xalalka wax soo saarka.

Waxa ugu dhow ikhtiraacida nuxurka farsamada iyo saamaynta la gaaray waa hab lagu helo aluminium hydroxide oo fiican iyadoo la isticmaalayo abuurka aluminium hydroxide, oo lagu shiiday aagga dusha sare ee gaarka ah, in ka badan ama la mid ah 1 m.²/g, halka iniinyaha lagu soo daro xalka aluminate qadar ahaan si dusha sare ee guud u satco kiimikadeeda sidaas darteedna, waxqabadka iniinuhu wuu hooseeyaa, taasoo u baahan isticmaalka tiro badan oo iniin ah iyo kharashyo tamar oo sarreeya diyaarinta.

Saldhigga ikhtiraacida waa in la sameeyo hab lagu diyaariyo abuurka hydroxide-ka aluminiumka ah, kaas oo hubiya firfircoonidiisa sare ee abuurka iyo daahirnimadiisa kiimikada, taasoo ugu dambeyntii horseedda hoos u dhaca isticmaalka agabka iyo ilaha tamarta.

Ujeedadaas awgeed, habka loo soo saaro aluminium hydroxide, oo ka kooban shiidi aluminium hydroxide abuurka, isku darka iniinaha la jajabiyey xalka buuxa iyo soo saarista joojinta ka dhalatay walaaqidda, abuurka aluminium hydroxide ee la jajabiyey uumiga 120-250^{ku saabsan}C. Isku darka iibso profile oo leh biyo-joojin ka kooban 50-300 kg/m³Budada aluminium hydroxide, kaas oo loo isticmaalo sidii abuurka.

Waxyaabaha ku habboon ee sodium oksaydh ee marxaladda dareeraha ah ee joojinta si loo ilaaliyo 0.05 ilaa 5 g/L.

Shiidida aluminium hydroxide uumi ah 120-250^{ku saabsan}Waxay bixisaa helitaanka aluminium hydroxide oo kiimiko ahaan saafi ah firfircoon oo abuurka sare leh. Baadh tirada dildilaaca, jajabyada iyo geesaha, kuwaas oo leh qaab-dhismeed aan qaab lahayn.

Qaab-dhismeedka dusha sare ee la cayimay wuxuu go'aamiyaa firfircoonida abuurka sare marka loo isticmaalo aluminium hydroxide sidii abuurka.

Saamaynta ugu badan waxaa la gaaraa marka heerkulka uumiga ee qolka shiididu uumigu yahay 120-250^{ku saabsan}C.

Marka heerkulku hoos uga dhaco 120^{ku saabsan}Iyadoo dhaqdhaqaaqa kiimikada ee dusha sare ee hydroxide aluminium la jajabiyey ay la mid tahay hababka kale ee shiidi.

Heerkulku wuxuu ka sarreeyaa 250^{ku saabsan}Iyadoo ficil ahaan aysan kordhin dhaqdhaqaaqa kiimikada ee dusha sare, si kastaba ha ahaatee, kororka kharashka tamarta kulaylka ee diyaarinta abuur.

Marka walxaha adag ee ku jira joojinta biyaha la helo ka dib isku darka paraphilias ee uumiga, joojinta firfircoonida abuurka ugu badnaan 50-300 g/l.

Hoos u dhaca ku jira adkaha ku jira joojinta ayaa ka hooseeya 50 g/l wax saameyn ah kuma yeelanayso dhaqdhaqaaqeeda qaawan, laakiin habkaas wuxuu keenayaa xaddi badan oo biyo ah, kaas oo u baahan kharash dheeraad ah oo uumi-baxa.

Kordhinta isku-darka adkaha ku jira biyaha oo ka sarreeya 300 g/l oo ka mid ah firfircoonideeda qaawan ayaa hoos u dhacaysa. Tani waxaa sababa hoos u dhaca x waa nooc aashito-saldhig ah.

Waxyaabaha ku jira sodium oksaydh ee marxaladda dareeraha ah ee joojinta biyaha ee u dhaxaysa 0.05-5 g/l waxay bixisaa firfircoonideeda ugu badan ee abuurka.

Xadka hoose ee fiirsashada waxaa xaddidaya waxa ku jira aluminium hydroxide alkali ah oo lagu dhaqo intracrystalline, kaasoo u imanaya shiidi.

Marka fiirsashada sodium oksaydh ee ka sarreysa 5 g/l joojinta firfircoonida abuurka ay yaraato sababtoo ah kala dirista qaab-dhismeedka aan qaab-dhismeedka lahayn ee dusha sare ee abuurka.

Habka la soo jeediyay ee lagu soo saarayo aluminium hydroxide waxaa lagu sameeyaa iyadoo la isticmaalayo qalabka la soo saaray oo loo isticmaalo warshadaha guryaha: nooca jet mill nooca ES-06; SP-1, iwm.

Shiididda mishiinka jet-ka waxay dhacdaa iyada oo aan la isticmaalin warbaahinta shiididda iyadoo la adeegsanayo mabda'a walxaha la qiiqi karo marka ay isku dhacaan walxaha. Isticmaalka mishiinnada jet-ka ayaa loo baahan yahay si loo hubiyo xuduudaha la soo jeediyay ee habka iyo helitaanka natiijada farsamo ee loo baahan yahay.
