Kazhinji, zvidhinha zvakakwirira zvealuminium hazvifanirwe kushandiswa muchoto chealkaline. Nekuda kwekuti alkaline uye acidic medium inewo chlorine, inopinda mukati meakadzama madhinha ealuminium akakwirira muchimiro chegradient, izvo zvinozoita kuti chidhinha chinoramba chiputsike.
Iyo yakakwira aluminium zvidhinha mushure mekukurwa kwemhepo yealkaline yakatsetseka yakatsemuka. Kukukurwa uku kunoumbwa nemafuta grey, magasi anopisa, uye alkaline zvikamu mune zvimwe zvigadzirwa. Izvi zvikamu zvinosangana nechikamu chegirazi uye mullite dombo mune yakakwira aluminium zvidhinha.
High-aluminium zvidhinha izvo zvakasvibiswa alkaline zvichaonekwa pamusoro. Kupisa gasi makomisheni kuchagadzirawo lure nitrate, sedimentation mumukana wezvidhinha zvakakwirira zvealuminium; kuita kwemazaya echando anogadzirwa kuchaumba chikamu chitsva chakaoma. Kana mvura isina lucky nitriles yasangana neyakagadzirwa vagram, iyo anti -vaporization reaction ichaitika, zvichiita kuti chidhinha chealuminium chakakwira kutsemuka kana kudonha. Mukuwedzera, kupisa kwekushisa kwakakombawo kune refractory brick corrosion. Nekuda kwekukukurwa kweFang quartz, Skywine, uye quartz crystal silica. Kushandiswa kwematairi emoto kuchave kwakakomba kupfuura kutonhora kwenoodles.
Kukuvadzwa kwezvidhinha zvesilicon dioxide zvakare kwakanyanya. Iyo silica inonyungudutswa mune yakakwirira aluminium zvidhinha -liquid chikamu. Iyo inonyungudika rombo rakanaka nitrate uye yakaderera-inonyungudika nzvimbo yesilicon matombo inoumba huwandu hukuru hwechikamu chemvura. Iyo yakakwirira iyo silica yemukati muzvidhinha, iyo yakakura huwandu hwechikamu chemvura. Yakawandisa nhanho yemvura inozokanganisa yakakwira aluminium zvidhinha. Silicon silicon zvakare yakakuvadzwa kune zvidhinha. Nekuti iyo yemahara silica inopedzwa, chikamu cheMo Lai Shi chichabviswa. Mushure mokupindura kwe lickle nitrate uye mullite dombo rinogona kukonzera kuparadza kuwedzera kwepamusoro aluminium brick.
Yakakwirira aluminium zvidhinha ine yakanakisa kupikisa kune yakakwirira tembiricha uye abrasion. Iwo anoshandiswa zvakanyanya mumitsetse yezvakasiyana mavira indasitiri, senge blast furnaces, hot air furnaces, uye rotary kilns. Nekudaro, mumhepo yealkaline indasitiri yevira, kushandiswa kwepamusoro alumina zvidhinha kunogumira.
Iyo kemikari yemhando yepamusoro yealuminium zvidhinha inoita kuti varambe mhedzisiro yenzvimbo dzine acidic. Zvisinei, munzvimbo ine alkaline yakawanda, yakadai semashini esimende kana magirasi egirazi, zvidhinha zvakakwirira zvealuminium zvinopindirana nealkali metal oxides, zvichiita kuti zvidhinha zviputike uye zviparare. Kuita pakati peAl2O3 zvidhinha uye alkali metal oxides zvinowanzokonzera kuumbwa kwealkali aluminosilicate gel, iyo ine nzvimbo yakaderera yekunyunguduka uye inogona kuyerera nyore nyore kuburikidza nekuputika.
Kugadzirisa dambudziko iri, nzira dzinoverengeka dzakashandiswa kuvandudza kushorwa kwearuminiyamu zvidhinha zvakakwirira kune alkaline nharaunda. Imwe mhinduro ndeyekuwedzera magnesia kana spinel kune yakakwirira alumina zvidhinha. Iyo magnesia kana spinel ichaita nealkali metal oxides kuti iite yakagadzikana spinel phases, iyo inogona kuwedzera kupikisa kweAl2O3 zvidhinha kuputika kunokonzerwa nealkali reaction. Imwe mhinduro ndeyekuisa chivharo chekudzivirira pamusoro pepamusoro pealumina zvidhinha kudzivirira kutarisana zvakananga nemamiriro e-alkaline.
Muchidimbu, zvidhinha zvakakwirira zvealuminium zvine mashoma kushanda mu alkaline atmosphere industrial furnace lining. Kuti uwedzere kupikisa kweAl2O3 zvidhinha munzvimbo dzealkaline, zvinodikanwa kuwedzera mamwe maminerari kana machira kuti udzivise kuita kunokuvadza nealkali simbi oxides. Izvo zvakakosha kuti usarudze iyo yakakodzera zvinhu zveindasitiri yevira mbiru kudzikisa njodzi dzinogona kuitika uye kuchengetedza mitengo.
