Isitena esirhabaxa se-alumina ephezulu sisixhobo esirhabaxa esisebenza kakuhle esinomxholo we-alumina ongaphezulu kwama-48%. Sihluzwe nge-bauxite ye-premium kumaqondo obushushu aphezulu, siphumelela ngaphezu kwezitena zodongwe eziqhelekileyo ekumelaneni namaqondo obushushu aphezulu, uzinzo lwesakhiwo kunye nokumelana nokugqwala. Njengesixhobo esiphambili se-lining kwii-oven zemizi-mveliso, sisetyenziswa kakhulu kwi-metallurgy, isamente, iikhemikhali kunye namashishini ombane, sisebenza njengesisombululo esithembekileyo sokukhusela izixhobo zemizi-mveliso ezishushu kakhulu.
Iipropati eziphambili
Esi sitena sichaseneyo sisebenza kakuhle kakhulu kwiindawo zoshishino ezinzima, sisombulula ngempumelelo imiba eqhelekileyo ye-furniture efana nokuguqulwa, ukuxobuka kunye nobomi obufutshane benkonzo.
Ukungaguquguquki kwe-1750°C ukuya kwi-1800°C. Iinguqulelo ezikumgangatho ophezulu zimelana namaqondo obushushu angaphezu kwe-1800°C, zigcina ukusebenza okuzinzileyo ngaphandle kokuthamba okanye ukunyibilika ngexesha lokusebenza ixesha elide kumaqondo obushushu aphezulu.
Ubushushu bokuthambisa umthwalo obuphakathi kwe-1420°C–1500°C buyamelana nokuguquguquka koxinzelelo lobushushu obuphezulu, bugcina ukuqina komzimba wesithando kwaye bunciphisa umngcipheko wokonakala kwezixhobo.
Isakhiwo se-mullite esilungisiweyo simelana ngempumelelo nokukhukuliseka okuvela kwi-slag enyibilikisiweyo, ulwelo lwesinyithi kunye negesi yolwelo olurhabaxa, sithintela umonakalo we-lining kwaye sandise ubomi benkonzo yesithando somlilo.
Inyamezela ukuguquguquka rhoqo kobushushu ngaphandle kokuqhekeka okanye ukuxobuka. Amandla aphezulu okucinezelwa ayenza ikwazi ukumelana nokukhuhlana kwezinto ixesha elide kunye nokungqubana koomatshini.
Ukuqhuba ubushushu obuphantsi kunciphisa ukulahleka kobushushu besithando kwaye kuphucula ukusebenza kakuhle kwamandla. Kunciphisa ukugcinwa kunye nokutshintshwa rhoqo, kunciphisa iindleko zokusebenza zexesha elide.
Izicelo eziphambili zeShishini
Ezi zitena zifumaneka kwiindidi ezahlukeneyo (48%–80% Al₂O₃), zihambelana neemeko ezahlukeneyo zobushushu obuphezulu. Zilungele kakhulu izitovu zesinyithi, iiladle zentsimbi kunye nezitovu zokufudumeza kwishishini lentsimbi. Zikwasebenza njengelayini eqinileyo kwiitovu ezijikelezayo zesamente, iitovu zelayimu, iiboyila zoshishino, izitovu zempendulo yamakhemikhali, iitovu zeglasi kunye neetovu zeseramikhi.
Kutheni Ukhetha Thina
Sinikezela ngezitena ezipheleleyo ze-alumina ephezulu ezirhabaxa kwiimo eziqhelekileyo nezenziwe ngokwezifiso, kuquka iintlobo ezikhaphukhaphu nezinzima. Zenziwe nge-bauxite ecocekileyo kakhulu ngeenkqubo ezingqongqo zokusila, iimveliso zethu zinomgangatho ozinzileyo, ubukhulu obuchanekileyo kunye nobomi benkonzo ende. Sinikezela ngezisombululo ezenzelwe wena, isikhokelo sokukhetha ngobuchule kunye nenkonzo epheleleyo emva kokuthengisa kubathengi behlabathi.
Nxibelelana nathi ukuze ufumane iingcebiso zobugcisa zasimahla kunye nekowuteshini yezitena ezinganyangekiyo ze-alumina ezikumgangatho ophezulu!
