Umgubo we-alumina yeyona nto iphambili eyenziwe nge-white fused alumina grit kunye nezinye izinto ezirhabaxa, ezineempawu zokuxhathisa kubushushu obuphezulu, ukumelana nokugqwala kunye neempawu ezizinzileyo. I-Nano-alumina XZ-LY101 lulwelo olungenambala nolucacileyo, olusetyenziswa kakhulu njengezongezo kwii-resin ezahlukeneyo ze-acrylic, ii-resin ze-polyurethane, ii-resin ze-epoxy, njl. Inokuba sisinyibilikisi esisekelwe emanzini okanye kwi-oyile, kwaye sinokugqunywa kwizinto zokugquma zeglasi, amatye anqabileyo, izixhobo zesixhobo esichanekileyo, njl.njl. kwaye iintlobo ezahlukeneyo zomgubo we-alumina zinokusetyenziswa okwahlukileyo. Oku kulandelayo kugxile ekuqaliseni ukusetyenziswa komgubo we-alumina we-α, γ, kunye ne-β-type.
Umgubo we-alumina oyi-1.α
Kwi-lattice ye-α-type alumina powder, ii-ion ze-oxygen zipakishwe ngokusondeleyo kwimo ye-hexagonal, i-Al3+ isasazwa ngokulinganayo kwiziko lokudibanisa i-octahedral elijikelezwe zii-ion ze-oxygen, kwaye amandla e-lattice makhulu kakhulu, ngoko ke indawo yokunyibilika kunye nendawo yokubilisa ziphezulu kakhulu. I-α-type oxidation I-Aluminium ayinyibiliki emanzini nakwi-asidi. Ikwabizwa ngokuba yi-aluminium oxide kushishino. Yinto esisiseko yokwenza i-aluminium yesinyithi; ikwasetyenziselwa ukwenza izitena ezahlukeneyo zokukhanyela, ii-crucibles zokukhanyela, iipayipi zokukhanyela, kunye nezixhobo zovavanyo ezishushu kakhulu; ingasetyenziswa njenge-abrasive, i-flame retardant I-Alpha alumina ecocekileyo kakhulu ikwayimpahla eluhlaza yokuvelisa i-corundum yokwenziwa, i-ruby yokwenziwa kunye ne-sapphire; ikwasetyenziselwa ukuvelisa i-substrate yeesekethe ezinkulu zanamhlanje.
2. umgubo we-γ-alumina
I-alumina yohlobo lwe-γ yi-aluminium hydroxide kwi-140-150 ℃ inkqubo yokuphelelwa ngamanzi kwindawo enobushushu obuphantsi, ishishini likwabizwa ngokuba yi-alumina esebenzayo, iglu ye-aluminium. Ulwakhiwo lwe-ion ye-oxygen oluqikelelwa kwicala elithe nkqo lesikhungo lubekwe ngokusondeleyo, i-Al3 + isasazwa ngokungaqhelekanga kwi-ion ye-oxygen ejikelezwe zizithuba ze-octahedral kunye ne-tetrahedral. I-alumina yohlobo lwe-γ ayinyibiliki emanzini, inokunyibilika kwisisombululo se-asidi enamandla okanye i-alkali enamandla, iya kufudunyezwa ukuya kwi-1200 ℃ yonke iya kuguqulwa ibe yi-α-type alumina. I-alumina yohlobo lwe-γ yinto enamaxolo, indawo yangaphakathi yomphezulu wegram nganye ukuya kumakhulu eemitha zesikwere, amandla aphezulu okutsalwa kwe-activity. Imveliso yemizi-mveliso idla ngokuba yisuntswana engenambala okanye epinki kancinci ene-resistance elungileyo yoxinzelelo. Kwishishini lokucocwa kwepetroleum kunye ne-petrochemical isetyenziswa ngokuqhelekileyo njenge-adsorbent, i-catalyst kunye ne-catalyst carrier; kwishishini kukho i-transformer oil, i-turbine oil deacidification agent, ikwasetyenziselwa uhlalutyo lwemibala; Kwilabhoratri kukho i-desiccant enamandla neutral, amandla ayo okomisa angaphantsi kwe-phosphorus pentoxide, emva kokusetyenziswa kwi-175 ℃ elandelayo yokufudumeza iiyure eziyi-6-8 nayo ingaphinda ivuselelwe kwaye isetyenziswe kwakhona.
Umgubo we-alumina we-3.β-alumina
Umgubo we-alumina wohlobo lwe-β ungabizwa ngokuba ngumgubo we-alumina osebenzayo. Umgubo we-alumina osebenzayo unamandla aphezulu oomatshini, u-hygroscopicity onamandla, awudumbi okanye uqhekeke emva kokufunxa amanzi, awunatyhefu, awunavumba, awunyibiliki emanzini nakwi-ethanol, une-adsorption enamandla ye-fluorine, esetyenziselwa kakhulu ukususa i-fluoride emanzini okusela kwiindawo ezine-fluorine eninzi.
I-alumina esebenzayo inamandla okufunxa amanzi kwiigesi, umphunga wamanzi kunye nolwelo oluthile. Emva kokufunxa amanzi, inokuvuselelwa ngokususa amanzi ngokufudumeza malunga ne-175-315°C. Ukufunxa nokuvuselela kungenziwa izihlandlo ezininzi. Ukongeza ekusetyenzisweni njenge-desiccant, ingakwazi nokufunxa umphunga kwi-oksijini engcolisiweyo, i-hydrogen, i-carbon dioxide, igesi yendalo njl.njl. yeeoyile zokuthambisa. Ikwasetyenziswa njenge-catalyst kunye ne-catalyst carrier kunye ne-catalyst carrier yokuhlalutya umaleko wombala.
