Calcined Alumina Ultrafine For High-Performance Refractories

Izimpushana ze-alumina ezibaliwe zenziwa ngokubala okuqondile kwe-alumina yemboni noma i-aluminium hydroxide emazingeni okushisa afanele ukuze aguqule abe yi-crystallineα-alumina ezinzile, bese egaya abe ama-micro-powder. Izimpushana ezincane ezibaliwe zingasetshenziswa esangweni lama-slide, imibhobho, nezitini ze-alumina. Ngaphezu kwalokho, zingasetshenziswa kuma-castable ane-silica fume kanye nama-alumina powders asebenzayo, ukunciphisa ukungezwa kwamanzi, i-porosity nokwandisa amandla, ukuzinza kwevolumu.

Imikhiqizo ye-alumina enempushana ye-alumina e-calcined njengempahla eluhlaza inamandla amahle kakhulu emishini, ubulukhuni obuphezulu, ukumelana nogesi okuphakeme kanye nokuhamba kahle kwe-thermal. I-aluminium calcined micropowder ingasetshenziswa kabanzi kumishini ye-elekthronikhi, izitsha zobumba zesakhiwo, ama-refractories, ama-abrasives, izinto zokupholisha, njll.

Ama-alumina abaliwe angama-alpha-alumina ahlanganisa ngokuyinhloko ama-agglomerate ahlanganisiwe amakristalu e-alumina angawodwana. Usayizi walawa makristalu ayisisekelo uncike ezingeni lokubala kanye nosayizi we-agglomerate ezinyathelweni zokugaya ezilandelayo. Iningi lama-alumina ama-calcined anikezwa umhlabathi (<63μm) noma umhlabathi ocolekile (<45μm). Ama-agglomerate awahlakazwanga ngokugcwele ngesikhathi sokugaya, okuwumehluko omkhulu kuma-alumina asebenzayo agaywe ngokugcwele yinqubo yokugaya inqwaba. Ama-alumina ane-calcined ahlukaniswa ngokuqukethwe kwesoda, usayizi wezinhlayiyana nezinga lokubala. Ama-alumina aqoshiwe aphansi naphansi asetshenziswa njengesigcwalisi se-matrix ukuze kuthuthukiswe ukusebenza komkhiqizo kokubunjwa okusekelwe kakhulu ezintweni zokusetshenziswa zemvelo.

Ama-alumina abaliwe anosayizi wezinhlayiyana ofana nama-aggregate amaminerali angaphansi futhi angashintsha kalula ama-aggregate abe nobumsulwa obuphansi. Ngokwandisa okuqukethwe kwe-alumina sekukonke kwezingxube nokuthuthukisa ukupakishwa kwezinhlayiyana zabo ngokufaka i-alumina enhle, izakhiwo zokuphikisa kanye nemishini, njenge-modulus eshisayo yokuqhekeka nokuphikiswa komhuzuko, ziyathuthukiswa. Isidingo samanzi se-aluminas e-calcined sichazwa inani lama-agglomerate asele kanye nendawo engaphezulu. Ngakho-ke, ama-alumina ama-calcined anendawo ephansi ephansi akhethwa njengama-fillers ezitini nasezintanjeni. Ama-alumina akhethekile akhaliwe anendawo ephakeme ephezulu, angangena esikhundleni sobumba ngempumelelo njenge-plasticizer ekuxubeni kwesibhamu ne-ramming. Imikhiqizo ephikisayo elungiswe ile mikhiqizo igcina izici zayo ezinhle zokufaka kodwa ibonisa ukushwabana okunciphe kakhulu ngemva kokoma nokudubula.

Calcined Alumina

Ama-aluminium Calcined for Refractories

Ngenxa yezakhiwo ezinhle kakhulu zokushisa okuphezulu kwe-a-Alumina, ama-Aluminas Calcined asetshenziswa ezinhlelweni eziningi eziphikisayo, zombili emikhiqizweni e-monolithic kanye neyakheke.

Ukusebenza Komkhiqizo
Ngokuya ngezinga lokugaya kanye nosayizi wekristalu, ama-Aluminas Calcined anika imisebenzi eyahlukene ekwakhiweni kwe-refractory.

Okubaluleke kakhulu yilezi:
• Thuthukisa ukusebenza komkhiqizo ngokwandisa okuqukethwe kwe-Alumina sekukonke kwalokhu kwakhiwa usebenzisa izinto zokusetshenziswa zemvelo ukuze kuthuthukiswe ukusebenza kwe-refractoriness kanye nezakhiwo zokukhanda.
• Thuthukisa ukupakishwa kwezinhlayiyana ngokwandisa inani lezinhlayiya ezinhle okuholela kumandla angcono emishini kanye nokungazweli ukuhuzuka.
• Yakha i-matrix ene-refractoriness ephezulu kanye nokumelana nokushaqeka okuhle okushisayo ngokusabela ngezingxenye zokuhlanganisa njenge-Calcium Aluminate Cement kanye / noma ubumba.
