1. Ulwakhiwo lweMathiriyeli kunye neNkalo yoLwakhiwo
1.1 Umxholo we-Alumina kunye ne-Crystal Phase Evolution
( Izitena zeAlumina zoLining)
Iibhloko ze-alumina zelinen zishinyene, iiseramics ezenziweyo ezirefractory ikakhulu zenziwe nge-aluminiyam oxide (Zimbini O ZITHANDATHU), ngomxholo oqhele ukuhluka kuwo 50% ukuya ngaphaya 99%, ukuphembelela ngokuthe ngqo ukusebenza kwabo kwizicelo zobushushu obuphezulu.
Amandla oomatshini, ukumelana nomhlwa, kunye nokuchaneka kwezi zitena kuphuculwe ngogqaliselo oluphezulu lwe-alumina njengesiphumo sokuqhubela phambili kwe-microstructure esomeleleyo elawulwa yi-α-alumina ekhuselekileyo ye-thermodynamically. (idayimani) iqonga.
Ngexesha lokuvelisa, iimveliso ze-precursor ezifana ne-bauxite ye-calcined, i-alumina edibeneyo, okanye i-alumina hydrate eyenziweyo idlula ngokudubula kobushushu obuphezulu (1400 °C– 1700 °C), intengiso yeqonga inguqu ukusuka kwiintlobo ze-alumina zenguqu (c, d) ukuya ku-α-Al Zimbini O ZINTATHU, ebonisa ukuqina okumangalisayo (9 kuluhlu lweMohs) kunye ne-melting factor (2054 °C).
Ulwakhiwo olunesiphumo lwepolycrystalline luqulathe iinkozo ezidityanisiweyo ze-corundum ezifakwe kwi-siliceous okanye i-aluminosilicate glassy matrix., ukwakheka kunye nobungakanani obulawulwa ngokucokisekileyo ukulungelelanisa ukuxhathisa ukothuka kwe-thermal kunye nokuqina kweekhemikhali.
Izithako ezincinci ezifana ne-silica (SiO ₂), titania (I-TiO ₂), okanye zirconia (ZrO ₂) inokwaziswa ukutshintsha imikhwa yokucula, khulisa ukuxinana, okanye ukwandisa ukuxhathisa kwii-slags ezithile kunye nokuguquguquka.
1.2 Microstructure, I-Porosity, kunye neMfezeko yoomatshini
Ukusebenza kakuhle kweebhloko ze-alumina lining kuxhomekeke kakhulu kwi-microstructure yazo, ngakumbi ukuhanjiswa kobungakanani beenkozo, i-pore morphology, kunye neempawu zesigaba sokudibanisa.
Izitena ezizezona zintle zibonisa, iipores ezisasazwa rhoqo (i-porosity evaliweyo ekhethiweyo) kunye ne-porosity encinci kakhulu evulekileyo (
I-Alumina Technology Co., Ltd igxile kuphando kunye nophuhliso, ukuveliswa kunye nokuthengiswa kwe-aluminium oxide powder, iimveliso ze-aluminium oxide, i-aluminium oxide crucible, njl., ukusebenzela i-elektroniki, iiseramikhi, Iikhemikhali kunye namanye amashishini. Ukususela ekusekweni kwayo kwi 2005, inkampani izibophelele ekuboneleleni abathengi ngezona mveliso kunye neenkonzo ezingcono. Ukuba ujonge umgangatho ophezulu iamina al2o3, nceda uzive ukhululekile ukuqhagamshelana nathi.
