Isingeniso esiyisisekelo se-alumina yokuhlanzeka okuphezulu

I-alumina ehlanzekile ephezulu iyikhemikhali enefomula yamakhemikhali ye-Al2O3, enobumsulwa obungaphezu kuka-99.99% esiwazi njenge-alumina ehlanzekile

ulwazi olubalulekile:

Ifomula yemolekyuli: Al2O3

Isisindo se-molecule: 102

Indawo encibilikayo: 2050 ℃

Amandla adonsela phansi athile: Al2O3 α Uhlobo 2.5-3.95g/cm3

Ifomu lekristalu: γ Uhlobo α uhlobo

Izici: ukuhlanzeka okuphezulu, usayizi wezinhlayiyana ungalawulwa ngokuya ngenqubo, ukusatshalaliswa kosayizi wezinhlayiyana ezifanayo, impushana emhlophe enganambitheki

ukuhlaziywa kwamakhemikhali:

Ukuhlanzeka okuphezulu kwe-aluminium oxide powder kuyimpushana emhlophe enobukhulu bezinhlayiyana ezifanayo, ukusabalalisa okulula, izakhiwo zamakhemikhali ezizinzile, ukuncipha kokushisa okuphakathi nendawo kanye nezakhiwo ezinhle ze-sintering;Ukuguqulwa okuphezulu nokuqukethwe kwe-sodium ephansi.Lo mkhiqizo uyisisekelo sokusetshenziswa kwemikhiqizo evikela ukushisa, engagqoki futhi ekwazi ukumelana nokugqwala, njengama-aluminium refractories aphezulu, imikhiqizo yobumba eqinile, ama-spark plugs ezimoto, izinto zokugaya eziphambili neminye imikhiqizo, enekhwalithi ethembekile. , indawo ephezulu yokuncibilika, ukuzinza okuhle kokushisa, ukuqina okuphezulu, ukumelana nokugqokwa okuhle, amandla aphezulu emishini, ukufakwa kahle kukagesi nokumelana nokugqwala.Isetshenziswa kakhulu kuma-refractories anomumo ne-amorphous Ukupholisha isibuko sezinto zokuhlobisa ezifana ne-refractory castable binder, amathuluzi abrasive ukumelana nokugqokwa, i-high-purity refractory fiber, izitsha zobumba ezikhethekile, izitsha zobumba zikagesi, izitsha zobumba, insimbi engagqwali negwadle.Ingakwazi ukuhlangabezana nezidingo zabasebenzisi ngokusetshenziswa okuhlukile nezimo zenqubo.I-alumina isebenzisa i-alumina yezimboni eyinhloko, i-aluminium hydroxide kanye nobuchwepheshe bokwengeza.Ngemuva kokubalwa kokuguqulwa kwesigaba sokushisa okuphansi, kusebenzisa ubuchwepheshe bokugaya obuthuthukisiwe kanye nenqubo yokukhiqiza i-alumina powder ecushiwe, ebonakala ngomsebenzi omkhulu kanye nosayizi wezinhlayiyana ezinhle.Ifaneleka ngokukhethekile emikhiqizweni emise okwe-amorphous refractories efana ne-refractory castables, ipulasitiki, izinto zokulungisa, izinto zokudubula kanye nezinto zokumboza.Idlala indima eqinile ekuthuthukiseni amandla ezinga lokushisa eliphezulu nokumelana nokugqwala kwama-refractories

Uhlelo lokusebenza oluyinhloko

I-1) I-Luminescent material: esetshenziswa njengezinto ezisetshenziswayo eziyinhloko ze-earth trichromatic phosphor, i-long afterglow phosphor, i-PDP phosphor ne-led phosphor;

I-2) I-ceramics esobala: esetshenziswa njengamashubhu e-fluorescent ezibani ze-sodium ezinomfutho ophezulu kanye namafasitela enkumbulo afundeka kuphela ahlelwa ngogesi;

3) Ikristalu eyodwa: esetshenziselwa ukukhiqiza i-ruby, isafire ne-yttrium aluminium garnet;

4) Amandla aphezulu kanye ne-aluminium ceramics ephezulu: esetshenziselwa ukukhiqiza ama-substrates esekethe ahlanganisiwe, amathuluzi okusika kanye nezinsimbi zokucwenga okuphezulu;

5) I-abrasive: i-abrasive esetshenziselwa ukukhiqiza ingilazi, insimbi, i-semiconductor nepulasitiki;

6) I-diaphragm: isetshenziselwa ukukhiqiza i-diaphragm yebhethri ye-lithium;

7）Okunye: esetshenziswa njenge-coating esebenzayo, i-adsorbent, i-catalyst kanye ne-catalyst carrier, i-vacuum coating, izinto zokusetshenziswa zengilazi ezikhethekile, izinhlanganisela, isigcwalisi se-resin, i-bioceramics, njll.
