Kazhinji, zvidhinha zvearuminiyamu zvakanyanya hazvifanirwe kushandiswa muchoto chemhepo ine alkaline. Nekuti alkaline neacidic medium zvine chlorine, zvinopinda muzvikamu zvakadzika zvezvidhinha zvearumina zvakanyanya muchimiro che gradient, izvo zvichaita kuti zvidhinha zvisingachashandiswi zviputsike.
Chidhinha chearuminiyamu chakakwirira mushure mekukukurwa kwemhepo ine alkaline chinotsemuka zvakatwasuka. Kukukurwa uku kunoumbwa nemafuta machena, magasi anotsva, uye zvinhu zvine alkaline mune zvimwe zvigadzirwa. Zvinhu izvi zvinosangana negirazi uye mullite stone mudhinha rearuminiyamu rakakwirira.
Zvidhinha zvealuminium zvine ngura zvakawanda zvinoonekwa pamusoro. Magasi anopisa achagadzirawo lure nitrate, sedimentation muburi rezvidhinha zvealuminium zvine ngura; kuita kwechando chinogadzirwa kuchaumba chikamu chitsva chakaoma. Kana nitriles dzisina mvura dzakabatana ne vagram inogadzirwa, maitiro ekudzivirira utsi achaitika, zvichiita kuti zvidhinha zvealuminium zvine ngura zvakawanda zvitsemuke kana kudonha. Pamusoro pezvo, ngura inodziya zvakare yakakomba zvikuru kune ngura yezvidhinha zvinoramba kusimba. Nekuda kwekukukurwa kwe Fang quartz, Skywine, uye quartz crystal silica. Kushandiswa kwemataira emoto kuchave kwakakomba kupfuura ma noodles anotonhora.
Kukuvadzwa kwezvidhinha zvesilicon dioxide kwakakombawo. Silica inonyungudutswa muchikamu chealuminium-liquid. Nitrate yerombo rakanaka inonyunguduka uye matombo esilicon ane nzvimbo yakaderera yekunyunguduka zvinoumba chikamu chikuru chemvura. Kana huwandu hwesilica muzvidhinha hwakawedzera, chikamu chemvura chinowanda. Chikamu chemvura chakawandisa chinokanganisa zvidhinha zvealuminium. Silica silicon inokuvadzwawo nezvidhinha. Nekuti silica yakasununguka inodyiwa, chikamu cheMo Lai Shi chinopwanyika. Mushure mekupindura kwe lickle nitrate uye mullite stone zvinogona kukonzera kuwedzera kukuru kwezvidhinha zvealuminium.
Zvidhinha zvearuminiyamu zvine simba guru rekudzivirira kupisa kwakanyanya uye kukwesha. Zvinoshandiswa zvakanyanya mumipendero yemidziyo yakasiyana-siyana yeindasitiri, yakadai semidziyo yekupisa, michina yemhepo inopisa, uye michina inotenderera. Zvisinei, mumhepo ine alkaline, kushandiswa kwemidziyo yearumina ine simba kwakaderera.
Hunhu hwemakemikari hwezvidhinha zve alumina zvine acid yakawanda hunoita kuti zvirambe zvichikanganiswa nemamiriro ekunze ane acid. Zvisinei, munzvimbo ine alkaline yakawanda, senge makiln esimende kana magirazi, zvidhinha zve aluminiyamu zvakawanda zvinosangana nealkaline metal oxides, zvichiita kuti zvidhinha zvitsemuke uye zviparare. Kuita pakati pezvidhinha zveAl2O3 nealkaline metal oxides kunowanzo guma nekuumbwa kwealkaline aluminosilicate gel, ine poindi shoma yekunyunguduka uye inogona kuyerera zviri nyore kuburikidza nepakati pemaburi.
Kugadzirisa dambudziko iri, nzira dzakasiyana-siyana dzakashandiswa kuvandudza kusimba kwezvidhinha zvealuminium zvakanyanya kumamiriro ealkaline. Imwe mhinduro ndeyekuwedzera magnesia kana spinel kuzvidhinha zvealumina zvakanyanya. Magnesia kana spinel ichaita zvinoenderana nealkali metal oxides kuti igadzire zvikamu zvespinel zvakagadzikana, izvo zvinogona kuwedzera kusimba kwezvidhinha zveAl2O3 pakutsemuka kunokonzerwa nealkali reaction. Imwe mhinduro ndeyekuisa coating yekudzivirira pamusoro pezvidhinha zvealumina zvakanyanya kudzivirira kusangana zvakananga nenzvimbo yealkaline.
Muchidimbu, zvidhinha zvealuminium zvine simba shoma mumidziyo yemuchina wealkaline. Kuti zvidhinha zveAl2O3 zvirambe zvakasimba munzvimbo dzine alkaline, zvakakosha kuwedzera mamwe mamineral kana macoatings kudzivirira kukanganisa nealkaline metal oxides. Zvakakosha kusarudza zvinhu zvakakodzera zvemidziyo yemuchina we ...
