Mashandisirwo: mukugadzira aruminiyamu hydroxide. Mushonga wekugadzira aruminiyamu hydroxide wakapwanywa pa 120 kusvika 250°C, musanganiswa weprofilebuy unosungana uye wokora kuti uwane mvura inonyungudika ine huwandu hwakasimba hwe 50 kusvika 300 g/l uye sodium oxide muchikamu chemvura che 0.05 - 5 g/l. Kunyungudika kwemvura kunoiswa mu supersaturated aluminate solution, zvichiisa extract yakawanikwa suspension pasi pekukurunga, kuparadzanisa aruminiyamu hydroxide yakaparadzaniswa kubva kune mother liquor uye kugezwa. 1 Cp f-crystals, 1 Il., tafura 1.

Kugadzirwa uku kune chekuita nekugadzirwa kwealuminium hydroxide, uye kunyanya kugadzirwa kwealuminium hydroxide yakanaka kubva mumvura ine sodium aluminate.

Nzira yekuwana aluminium hydroxide yakanaka [1] umo maitiro acho anoitwa muzvikamu zviviri. Muchikamu chekutanga, aluminate solution inobviswa nehydrochloric acid, uye aluminium hydroxide inobuda inoshandiswa sekuora kwembeu ye supersaturated aluminate solution kuora muchikamu chechipiri. Nekuda kweizvozvo, aluminium hydroxide ine chimiro chehydrargillite, iyo inoshandiswa kune zvinangwa zvakasiyana-siyana, semuenzaniso kune prigotovit, inoguma nekuora kwe caustic alkali aluminate solution. Aluminium hydroxide inobuda inoratidzwa nekupararira kwakanyanya uye chimiro chisina kusimba chezvikamu, zvichiratidza kuti ine basa rakawanda rembeu mukuora kwemhinduro dzealuminate.

Zvisinei, nzira iyi yekugadzirira mbeu inongogoneka chete kana uchishandisa mhinduro dzakagadzirirwa, dzisina tsvina dzine aluminate. Zvikasadaro, aluminum hydroxide inotorwa tsvina kubva mumushonga uye basa rembeu rinodzikira. Pamusoro pezvo, nekushandiswa kwenzira iyi nekuda kwekukurumidza kudzika uye kusefa, aluminum hydroxide inopihwa padanho rechipiri nenzira yekumisikidzwa. Muchiitiko ichi, zvese zvakagadzirwa padanho rekutanga remunyu zvinowira padanho rechipiri, zvichisvibisa chigadzirwa chekutanga uye zvichitenderera munzvimbo yemhinduro dzekugadzira.

Nzira iri pedyo nekugadzirwa kwezvinhu zvitsva uye mhedzisiro inowanikwa inzira yekuwana aluminium hydroxide yakanaka sembeu inoshandisa aluminium hydroxide, yakakuyiwa kusvika panzvimbo chaiyo, inopfuura kana kuti yakaenzana ne 1 m.²/g, nepo mbeu ichiiswa mumusanganiswa wealuminate muhuwandu hwakaita kuti pamusoro pese pasatco makemikari ayo uye nekudaro, basa rembeu rakaderera, izvo zvinoda kushandiswa kwembeu yakawanda uye mari yakawanda yesimba mukugadzirira kwayo.

Hwaro hwechigadzirwa ichi ndechekugadzira nzira yekugadzira mbeu yealuminium hydroxide, iyo inoita kuti mbeu dzayo dzishande zvakanaka uye kuti ive yakachena, izvo zvinozoita kuti kushandiswa kwezvinhu nesimba kuderedzwa.

Nechinangwa ichi, nzira yekugadzira aruminiyamu hydroxide, inosanganisira kukuya mbeu yearuminiyamu hydroxide, kusanganisa mbeu yakapwanywa nemushonga une supersaturated uye kubvisa suspension inobuda nekukurunga, mbeu yearuminiyamu hydroxide yakapwanywa nemhepo inopisa pa 120-250.^nezveC. tenga musanganiswa weprofile ine mvura inogashira ine 50-300 kg/m2³ivhu realuminium hydroxide, rinoshandiswa sembeu.

Kuwanda kwe sodium oxide muchikamu chemvura che suspension kwakakodzera kuti kurambe kuri pakati pe 0.05 kusvika 5 g/L.

Kukuya aluminium hydroxide steam pa 120-250^nezveInoita kuti aruminiyamu hydroxide iwane mishonga yakawanda. Tsvaga huwandu hwemaburi, machipisi nemaburi, ane chimiro chisina chimiro.

Maumbirwo epamusoro akasarudzwa anosarudza mashandiro ayo embeu pakushandisa aruminiyamu hydroxide sembeu.

Mhedzisiro yepamusoro inowanikwa kana tembiricha yemhepo mukamuri yekukuya iri 120-250^nezveC.

Kana tembiricha yadzikira pasi pe120^nezveNekushanda kwemakemikari pamusoro pearuminiyamu yakapwanyika hydroxide kwakafanana nedzimwe nzira dzekukuya.

Kupisa kunowedzera pamusoro pe250^nezveNezvinenge zvisingawedzere mashandiro emakemikari pamusoro, zvisinei, mitengo yesimba rekupisa iri kuwedzera pakugadzirira mbeu.

Kana zvakazara mu aqueous suspension zvakawanikwa mushure mekusanganiswa kwe condensation paraphilias, 50-300 g/l yembeu yekushanda inomiswa zvakanyanya.

Kudzikira kwehuwandu hwechinhu chakasimba chiri muchimiro chesimbi kuri pasi pe50 g/l hapana chinokanganisa mashandiro aro, asi mukuita izvi mvura yakawanda inobuda, izvo zvinoda mari yakawanda kuti iparadzwe.

Kuwedzera kwehuwandu hwezvinhu zvakasimba mumvura inomiswa pamusoro pe300 g/l yekushanda kwayo kuri kudzikira. Izvi zvinokonzerwa nekudzikira kwe x imhando ye acid-base.

Kuwanda kwe sodium oxide muchikamu chemvura che aqueous suspension chiri pakati pe 0.05-5 g/l kunoita kuti mbeu ishande zvakanyanya.

Muganho wakaderera wekuwanda kwesimbi unogumira pahuwandu hwesimbi yakashambidzwa nealuminium hydroxide inogadzirwa ne intracrystalline, iyo inosvika pakukuya.

Kana huwandu hwesodium oxide huri pamusoro pe5 g/l, kushanda kwembeu kunodzikira nekuda kwekunyungudika kwemaumbirwo asina chimiro pamusoro pembeu.

Nzira inokurudzirwa yekugadzira aluminium hydroxide inoitwa nekushandisa michina yakagadzirwa uye inoshandiswa mumafekitori epamba: jet mill type ES-06; SP-1, nezvimwewo.

Mujet mill, kukuya kunoitika pasina kushandisa grinding media kunoshandiswa musimboti wezvinhu zvinopfungaira kana zvidimbu zvikabonderana. Kushandisa jet mills kunodiwa kuti uve nechokwadi chekuti parameters dzakarongwa dzemaitiro acho uye kuwana mhedzisiro yehunyanzvi inodiwa.

Mu boron ine vanhu vanotonhodza vanoyerera. Kutonhodza kwemvura inogadzirwa. Kana utsi uhu hwaungana uye hukagadzira aluminium hydroxide inomiswa mumvura, iyo mushure mekunyoroveswa inoshandiswa muKea.

Aruminiyamu hydroxide inobva muhopper 1 nescrew 2 inoiswa muchubhu inomhanyisa jet mill 3. Machubhu anomhanyisa aruminiyamu hydroxide anokurumidza kumanikidza kumanikidzwa kwemhepo. Matanda anogovana anobonderana, anopwanywa uye anobviswa mumhepo muchikamu chinoparadzanisa centrifugal 4. Matumbu makuru anodzoserwa kuchigayo paDorisol, uye anopwanywa kusvika pahukuru hwetunhu hwaunoda huchachengetwa musystem yekuunganidza guruva 5. Paraphilias stream inotonhodzwa, inokonzereswa, mvura inonyungudutswa 6 inokonzereswa mu thickener 7, inosanganiswa ne supersaturated aluminate solution 8 uye inopinda mu reactor 9, iyo inochengetwa ichikurunga. Mushure mekunyikwa aruminiyamu hydroxide inoparadzaniswa nedoro reamai mufirita 10, inogezwa uye inotumirwa kumutengi.

Kuenzanisa data kubva mukuyedza kwakawanda kunoratidza kuti kukuyiwa kwealuminium hydroxide mujet mill kunopfuta pa120-250^nezveNekushandisa uye kunotevera kwemvura inonyungudutswa yezvinhu zvine upfu zvine 50-300 g/l yakasimba sembeu, zvinovandudza kushanda zvakanaka kwemaitiro uye kunaka kwechigadzirwa chapera nekuda kwekugadzirwa kwembeu yakachena ine makemikari, kushanda kwembeu kwakawanda.

Industrial Prime p 1 kg yealuminium hydroxide ine avhareji yehukuru hwekristaro ye40 μm steam yakakuyiwa mumuchina wekugadzira jeti murabhoritari. Tembiricha yesteam pamusuwo wemuchina wekugadzira jeti yaive 160^nezveNekumanikidzwa kwe7 MPa. Tembiricha mukamuri yekukuya 140^nezveC. Avhareji yehukuru hwemakristaro mushure mekukuya kusvika 2.0 μm.

Aruminiyamu hydroxide yakakuyiwa, yakagadzirwa muchimiro chemusanganiswa weparaphilias, inobata mumhando yefirimu ine boron. Kuunganidzwa kwemhepo inobuda mumvura inotonhora iri mu boron. Mushure mekusanganiswa kwemvura, vanhu vanoyerera vanogamuchira 10 l yesimbi ine 100 g/l yealuminium hydroxide yakakuyiwa uye 0.4 g/l yesodium oxide muchikamu chemvura.

0,04 l yekumisikidza kwemvura inosanganiswa ne 1 litre ye aluminate solution ine, g/l: Na₂O_ku130,9; Al₂O₃137,2; Nhamba₂CO₃20,3; NaCl 12,2; Na₂SO₄5,4; kabhoni yeorganic (Corg.) 12,4. Kumiswa kunobuda kunoiswa mureactor uye kunochengetwa pasi pekukurunga pa55^nezveC kwemaawa makumi maviri nemana

Kuora kwealuminate solution kwaive 50.2% yehuwandu hwekugadzirwa kwealuminum hydroxide 109,4, avhareji yehukuru hwemakristaro ari musediment ye3.6 μm, huwandu hwetsvina mualuminum hydroxide, Na₂O 0,42; Fe₂O₃0,021; SiO₂0,018.

Mhedzisiro yekuedza mukati mehurongwa hwakarongwa, hwakanyanya kunaka uye hunopfuura C, kushanda zvakanaka kwekuora kunowanikwa patembiricha iri mukamuri yekukuya 120-250.^nezveKana, zviri mukati mealuminium hydroxide yakapwanywa mumvura inomiswa 50-300 g/l uye zviri mukati mesodium oxide muchikamu chemvura inomiswa 0.05-5 g/L.

1. Nzira yekugadzira Aluminum HYDROXIDE, inosanganisira kukuya mbeu yealuminium hydroxide, kusanganisa mbeu yealuminium hydroxide yakapwanywa kubva mu supersaturated aluminum solution, kukwegura kwe suspension inobuda nekukurunga, Dhipatimendi rakaburitsa aluminum hydroxide kubva mu liquor yaamai ndokugeza, inozivikanwa nekuti kukuya kwealuminum hydroxide kwaiitwa ne steam pa 120 250^oNeprofile yakawanikwa, tenga suspension inonamira uye inokora kuti uwane suspension yemvura ine huwandu hwakasimba hwe50 kusvika 300 g/l uye inoiswa mumushonga une supersaturated.

2. Nzira iyi inoenderana nepeji 1, inoratidzwa nekuti huwandu hwesodium oxide muchikamu chemvura chemvura inomiswa hunoramba huri pakati pe0.05 kusvika 5.0 g/L.
