Kazhinji, zvidhinha zvearuminiyamu zvakanyanya hazvifanirwe kushandiswa muchoto chemhepo ine alkaline. Nekuti alkaline neacidic medium zvine chlorine, zvinopinda muzvikamu zvakadzika zvezvidhinha zvearuminiyamu 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 zvine alkaline zvichaonekwa pamusoro. Magasi anopisa achagadzirawo lure nitrate, sedimentation muburi rezvidhinha zvealuminium zvine ngura yakawanda; kuita kwechando chakagadzirwa 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 yekupisa yakanyanyawo kune ngura yezvidhinha zvisingadiwi. Nekuda kwekukukurwa kwe Fang quartz, Skywine, uye quartz crystal silica. Kushandiswa kwemataira emoto kuchave kwakanyanya 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 zvealuminium zvine simba guru rekudzivirira kupisa kwakanyanya uye kukwesha. Zvinoshandiswa zvakanyanya mumipendero yezvoto zvakasiyana-siyana zvemaindasitiri, zvakaita sezvitofu zvinoputika, zvitofu zvinopisa, uye zvitofu zvinotenderera. Zvisinei, mumhepo ine alkaline, kushandiswa kwezvidhinha zvealuminium zvine simba kwakanyanya.
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 konzera kuumbwa 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 zvearuminiyamu zvakanyanya kumamiriro ealkaline. Imwe mhinduro ndeyekuwedzera magnesia kana spinel kuzvidhinha zvearuminiyamu 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 zvearuminiyamu 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 ...
