Uthini umahluko phakathi kwezitena ze-corundum mullite kunye nezitena eziphezulu ze-alumina?

Umahluko omkhulu phakathi kwezitena ze-corundum mullite kunye nezitena eziphezulu ze-alumina yisigaba se-crystal, kwaye ukubonakala kunye nombala kuhluke ngandlel ‘ithile. Esona sizathu siphambili ngumlinganiselo wezinto ezikrwada. Nceda ujonge intshayelelo eneenkcukacha engezantsi.

Isitena seCorundum mullite

Inamandla alungileyo obushushu obuphezulu, ukuxhathisa ubushushu obuphezulu, ukuxhathisa ukothuka kwe-thermal kunye nokuxhathisa ukubola. Iimpawu ezibonakalayo kunye neekhemikhali zezitena eziqhelekileyo ze-corundum mullite ziyi-Al2O3> 85%, Fe2O30.45%, i-porosity ebonakalayo 19%, amandla aqhelekileyo obushushu obuqhelekileyo be-55MPa, ubushushu bokuthambisa umthwalo ngaphezu kwe-1700 ℃, utshintsho lomgca wokufudumeza (1600 ℃, 3h) -0.1 %.

Izitena zealumini ephezulu

Umxholo we-aluminium oxide yi-48% ukuya kwi-85%, enokuthi yahlulwe ngokukodwa, iprayimari, isekondari, i-tertiary, njl. Fe2O30.45%, i-porosity ecacileyo yi-19%, amandla oxinzelelo kwiqondo lokushisa kwegumbi lidlula i-55MPa, ubushushu bokunciphisa umthwalo budlula. I-1700 ℃, utshintsho lwentambo yokufudumeza (1600 ℃, 3h) -0.1%, ukuxhathisa ukothuka kwe-thermal (1100 ℃ ukupholisa kwamanzi) ngaphezu kwamaxesha angama-30. Imveliso isebenzisa i-aluminiyam i-alum clinker ephezulu njengeyona nto iphambili, udongwe oluthambileyo kunye ne-pulp yenkunkuma kunye ne-liquid yephepha njenge-agent edibeneyo, kwaye udaka olunamaqhekeza amanqanaba amaninzi lwenziwa ngokubunjwa koxinzelelo oluphezulu, ukomisa kunye nokudubula kobushushu obuphezulu.
