Ifu ya Alumina

Tuzakora ibishoboka byose kugirango tube abantu badasanzwe kandi beza, kandi twihutishe intambwe zacu zo guhagarara imbere yurwego rwisi yose yo mu rwego rwo hejuru ndetse n’ikoranabuhanga rikomeye kuriIfu ya Alumina, Ibisabwa byose muri wewe bizishyurwa nitwitayeho!

Ibintu bitanu biranga ifu ya alumina yuzuye

1. Kurwanya imiti;
2. alumina-yera cyane, ibirimo alumina birenze 99%;
3. Kurwanya ubushyuhe bwinshi, gukoresha bisanzwe kuri 1600 ℃, igihe gito 1800 ℃;
4. Kurwanya ubukonje nubushyuhe butunguranye, ntibyoroshye guturika;
5. Ifata guswera kandi ifite ubucucike bukabije.
1. Gukoresha ifu ya α ubwoko bwa alumina

Muri kasitori ya kirisiti yifu ya α-ya alumina, ion ya ogisijeni ipakiye hafi muri hexagons, kandi Al3 + ikwirakwizwa muburyo bukomatanyije muri octahedral ihuza ikigo kizengurutswe na ion ogisijeni.Ingufu za lattice nini cyane, aho gushonga hamwe no guteka biri hejuru cyane.α-okiside ya Aluminium ntishobora gushonga mumazi na aside.Yitwa kandi oxyde ya aluminium mu nganda.Nibikoresho fatizo byibanze byo gukora aluminium;irakoreshwa kandi mu kubumba amatafari atandukanye yangiritse, umusaraba wangiritse, imiyoboro itavunika, hamwe nibikoresho byo gupima ubushyuhe bwo hejuru;irashobora kandi gukoreshwa nka abrasives na flame retardants.Abakozi, abuzuza, nibindi.;ubuziranenge-α ubwoko bwa alumina nabwo nibikoresho fatizo byo gukora corundum artificiel, ruby ​​artificiel na safiro;irakoreshwa kandi mukubyara umusaruro munini ugezweho wuzuzanya.

Alumina ikora ifite ubushobozi bwo guhitamo gaze, imyuka y'amazi hamwe nubushuhe bwamazi.Iyo adsorption imaze guhaga, irashobora kubyutswa no gushyushya nka 175-315 ° C kugirango ikureho amazi.Adsorption n'izuka birashobora gukorwa inshuro nyinshi.Usibye gukoreshwa nka desiccant, irashobora kandi kwamamaza imyuka yamavuta yo kwisiga ava muri ogisijeni yanduye, hydrogène, dioxyde de carbone, gaze naturel, nibindi.

Ifu ya Alumina nigikoresho nyamukuru cyo gukora umusaruro wa aluminium.Ifite ibiranga kuguruka kworoheje, gutembera neza, gushonga byoroshye no kwinjiza fluorine ikomeye.Irakwiriye kubyara aluminium yicyuma na electrolysis yumunyu.Nibikoresho byingenzi byingenzi kugirango habeho umusaruro wa corundum, ububumbyi n’inganda.
