Incazelo emfushane

I-Tabular Alumina iyinto ehlanzekile efakwe emazingeni okushisa aphezulu - aphezulu ngaphandle kwezithasiselo ze-MgO ne-B2O3,I-microstructure yayo iyisakhiwo se-polycrystalline esinezinhlangothi ezimbili esinamakristalu amakhulu akhule kahle a-α - Al2O3.I-Tabular Alumina inezimbotshana eziningi ezivaliwe ezincane ku-crystal yomuntu ngamunye , okuqukethwe kwe-Al2O3 kungaphezu kuka-99 % .Ngakho-ke inokuqina okuhle kwevolumu nokumelana nokushaqeka okushisayo , ukuhlanzeka okuphezulu nokuphikisa , amandla amahle kakhulu emishini , ukumelana nokuhuzuka ngokumelene ne-slag nezinye izinto.

Ithebula namanye ama-Aggregate

Ama-aggregates awumgogodla wokubunjwa okuphikisayo futhi ahlinzeka ngokuzinza kobukhulu emikhiqizweni ephikisayo.Amafrakshini amaholo angeza ukushaqeka okushisayo kanye nokumelana nokugqwala futhi izinhlawulo ezihlanganisiwe zithuthukisa ukusatshalaliswa kosayizi wezinhlayiyana futhi andise ukuphikiswa komkhiqizo.

Ikhwalithi engaguquki ye-Tabular alumina ingumphumela wenqubo ye-sinter elawulwa kahle enamazinga okushisa okushisa angaphezu kuka-1800 ° C. Ukusetshenziswa kwezithando zokushisa eziphakeme ezinobuchwepheshe besimanje kuvumela ukuminyana kwezinto eziluhlaza ezikhethiwe ngaphandle kwezinsiza ze-sintering ezingase kunomthelela omubi ezindaweni zokushisa eziphezulu ze-refractories.

Njengomphumela wenqubo ye-sinter, ama-aggregate abonisa ukwakheka okufanayo kwe-mineralogical kanye namakhemikhali kuzo zonke izingxenyana.Ngokuphambene nemikhiqizo ehlanganisiwe lapho ukungcola kunqwabelana khona ezinhlawulweni, ukusetshenziswa kwe-sintered aggregates ekwakhiweni kwe-refractory kuqinisekisa ukuziphatha okuzinzile nokuthembekile.

I-Junsheng inikezela ngosayizi abahlukahlukene bezilinganiso ukusuka kumafrakshini amaholoholo ukuya kosayizi abacolekile abangu-<45 μm kanye no-<20 μm.Ukuchotshozwa nokugaya kulandelwa izinyathelo ezijulile zokususa ama-ayina eziholela ensimbi yamahhala ephansi kakhulu phakathi kwamafrakshini ahlukahlukene.

Inqubo Yokukhiqiza ye-Tabular alumina

Isicelo Of Tabular Alumina

I-Tabular Alumina iyimpahla ekhethwayo kuzinza ezisebenza kahle ezingakakhiwe ezisetshenziswa ezimbonini ezihlukahlukene ezihlanganisa insimbi , isisekelo , usimende , ingilazi , i- prtrochemical , i-ceramic kanye nokushiswa kwemfucuza .Ezinye izinhlelo zokusebenza ezivamile ezinganqamuki zihlanganisa ukusetshenziswa kwayo kufenisha yomlilo kanye nokuhlunga kwensimbi.
