1. Isakhiwo Sempahla kanye Nesimo Sesakhiwo
1.1 Okuqukethwe kwe-Alumina kanye ne-Crystal Phase Evolution
( Izitini ze-Alumina Lining)
Amabhulokhi e-alumina aqinile, izitsha zobumba eziphikisayo ezakhiwe ikakhulukazi ezakhiwe nge-aluminium oxide (Babili O YESTHUPHA), ngokuqukethwe okuvamise ukuhluka 50% kuze 99%, ezithonya ngqo ukusebenza kahle kwazo ezinhlelweni zokushisa eziphezulu.
Amandla emishini, ukumelana nokugqwala, kanye nokungaguquki kwalezi zitini kuyathuthuka ngokugxila kwe-alumina ephakeme ngenxa yokuthuthuka kwe-microstructure ehlala isikhathi eside ebuswa i-α-alumina evikelekile ngokwe-thermodynamically (idayimane) esiteji.
Ngesikhathi sokukhiqiza, imikhiqizo eyandulelayo njenge-bauxite e-calcined, i-alumina ehlanganisiwe, noma i-alumina hydrate yokwenziwa idlula ekudubuleni okunezinga lokushisa eliphezulu (1400 °C– 1700 °C), ukuguqulwa kwesiteji sokukhangisa kusuka ezinhlotsheni ze-alumina zesikhashana (c, d) ku-α-Al Two O THATHU, okubonisa ukuqina okumangalisayo (9 ebangeni le-Mohs) kanye nesici sokuncibilika (2054 °C).
Umphumela wesakhiwo se-polycrystalline uqukethe izinhlamvu ze-corundum ezixhumene ezishumekwe ku-siliceous noma i-aluminosilicate glass matrix., ukwakheka kanye nenani elilawulwa kahle ukulinganisa ukumelana nokushaqeka okushisayo kanye nokuqina kwamakhemikhali.
Izithako ezincane ezifana ne-silica (SiO ₂), titania (I-TiO ₂), noma i-zirconia (I-ZrO ₂) ingase yethulwe ukushintsha imikhuba yokucula, thuthukisa ukuminyana, noma uthuthukise ukumelana nama-slags athile kanye nokuguquguquka.
1.2 I-Microstructure, I-Porosity, kanye Nobuqotho Bemishini
Ukusebenza kahle kwamabhulokhi e-alumina lining kuncike kakhulu ku-microstructure yawo, ikakhulukazi ukusatshalaliswa kosayizi wokusanhlamvu, i-pore morphology, kanye nezimfanelo zesigaba sokubopha.
Izitini ezingcono kakhulu zibonisa kahle, ama-pores asakazwa njalo (i-porosity evaliwe ekhethiwe) kanye ne-porosity encane kakhulu evulekile (
Le nkampani Alumina Technology Co., Ltd., Ltd igxile ocwaningweni nasekuthuthukisweni, ukukhiqizwa nokudayiswa kwe-aluminium oxide powder, imikhiqizo ye-aluminium oxide, i-aluminium oxide crucible, njll., ukusebenzela ugesi, izitsha zobumba, izimboni zamakhemikhali nezinye. Selokhu yasungulwa ngo 2005, inkampani izibophezele ekuhlinzekeni amakhasimende ngemikhiqizo namasevisi angcono kakhulu. Uma ufuna izinga eliphezulu i-alumina al2o3, sicela ukhululeke ukuxhumana nathi.
Omaka: Izitini ze-Alumina Lining, i-alumina, i-alumina oxide
Zonke izindatshana nezithombe zivela ku-inthanethi. Uma kukhona izinkinga ze-copyright, sicela usithinte kusenesikhathi ukuze ususe.
