Alumina yakajairika inorganic isiri-simbi zvinhu, inoshandiswa zvakanyanya muindasitiri, kuvaka, zvemagetsi, mushonga uye mamwe minda.

Alumina Nhanganyaya

Alumina ichena kana isina-white powder ine molecular formula yeAl2O3 uye molecular uremu hwe101.96.Icho chiumbwa chinoumbwa nealuminium uye oksijeni, iyo ine yakakwirira yekunyungudika uye kuoma.Alumina chinhu chakakosha maindasitiri mbishi zvinhu, iyo inoshandiswa zvakanyanya mu ceramics, girazi, zvemagetsi, mushonga uye mamwe minda.

Zvenyama zvimiro zvealumina

Iwo emuviri zvimiro zvealumina anonyanya kusanganisira density, kuoma, kugadzikana kwekupisa, optical zvivakwa uye zvichingodaro.Density yealumina ndeye 3.9-4.0g/cm3, kuomarara ndiko kuomarara kweMohs 9, kugadzikana kwemafuta kwakakwira, uye nzvimbo yekunyungudika i2054 ℃.Uye zvakare, alumina zvakare ine yakanaka optical zvimiro uye yakakosha optical zvinhu.

Chemical properties yealuminium

Iwo emakemikari zvimiro zvealumina anonyanya kusanganisira kuita kwekuita neakasiyana makemikari zvinhu, asidhi uye alkali.Alumina inopindirana neasidhi kuita aruminiyamu munyu nemvura, uye nealkali kugadzira aruminiyamu hydroxide nemvura.Panguva imwecheteyo, alumina inewo zvinhu zve acidic oxides, iyo inogona kuita nemakemikari akawanda.

Kugadzirira nzira yealuminium

Nzira huru dzekugadzirira dzealuminium ikemikari nzira, nzira yemuviri uye zvichingodaro.Iyo kemikari nzira inonyanya kuburikidza ne neutralization reaction yealuminium munyu uye hydroxide kuwana aruminiyamu hydroxide, uyezve kuburikidza nekushisa kwakanyanya kupisa kuti uwane aluminium oxide.Iyo yemuviri nzira inonyanya kuburikidza neore decomposition, distillation, crystallization uye mamwe matanho ekuwana alumina.

Alumina application field

Alumina inoshandiswa zvakanyanya muindasitiri, kuvaka, zvemagetsi, mushonga uye mamwe minda.Mundima yeindasitiri, alumina inoshandiswa mukugadzira ceramics, girazi, machira uye zvichingodaro.Muchikamu chekuvaka, alumina inoshandiswa kugadzira magonhi, Windows, madziro emaketeni uye zvichingodaro.Mumunda wemagetsi, alumina inoshandiswa kugadzira mapuranga emagetsi, zvikamu zvemagetsi, nezvimwewo. Mumunda wemishonga, alumina inoshandiswa mukugadzirwa kwemishonga, zvigadzirwa zvemishonga nezvimwe zvakadaro.

Iyo tarisiro yekusimudzira yealumina

Nekuenderera mberi kwekusimudzira kwesainzi uye tekinoroji, iyo ndima yekushandisa yealumina inowedzera uye yakakura.Mune ramangwana, nekukurumidza kukura kwezvinhu zvitsva, simba idzva nemamwe minda, kudiwa kwealumina kucharamba kuchiwedzera.Panguva imwecheteyo, nekuenderera mberi kwekuvandudzwa kwezvinodiwa zvekuchengetedza kwezvakatipoteredza, tekinoroji yekugadzira yealumina icharamba ichivandudza, uye nzira dzekugadzira dzine hushamwari, dzinoshanda uye dzekuchengetedza simba dzichava maitiro ekusimudzira.

Alumina yakakosha inorganic isiri-metallic material, iyo ine huwandu hwakawanda hwekushandisa uye yakakosha yehupfumi kukosha.Mune ramangwana, nekukurumidza kukura kwezvinhu zvitsva uye simba idzva nemamwe minda, kudiwa kwealumina kucharamba kuchiwedzera, nepo tekinoroji yekugadzira alumina icharamba ichivandudza, nekuita mipiro yakakura mukusimudzira kwevanhu.
