Bauxite tiag tiag yog hais txog lub ntsiab lus dav dav rau ores uas tuaj yeem siv rau hauv kev lag luam, nrog gibbsite, boehmite lossis diaspore ua cov zaub mov tseem ceeb.Nws daim ntawv thov teb muaj ob yam ntawm cov hlau thiab tsis yog hlau.Bauxite yog cov khoom siv zoo tshaj plaws rau kev tsim cov hlau txhuas, thiab nws tseem yog daim ntawv thov tseem ceeb tshaj plaws.Nws noj nyiaj ntau dua 90% ntawm lub ntiaj teb tag nrho cov khoom tsim tawm bauxite.

bauxite yog dab tsi?

Bauxite yog cov av nplaum siv los ua cov khoom siv tseem ceeb rau kev tsim cov txhuas.Nws yog tsim los ua cov khoom seem nyob hauv ntau lab xyoo los ntawm cov tshuaj huab cua ntawm cov pob zeb uas muaj txhuas silicates.Nws tau pom thawj zaug hauv Fabkis xyoo 1821, thiab txij li ntawd tau pom nyob rau ntau qhov chaw thoob ntiaj teb.Ruiqifeng tau tsim muaj kev sib raug zoo nrog Guangxi ceg ntawm CHALCO, uas yog Tuam Tshoj tus loj tshaj plaws tsim ntawm alumina, thawj txhuas thiab txhuas ua cov khoom.

Bauxite siv nyob qhov twg?

Kev siv cov bauxite uas tsis yog xim hlau feem ntau yog cov khoom siv raw rau cov ntaub ntawv refractory, cov ntaub ntawv abrasive, tshuaj thiab siab alumina cement.Txawm hais tias qhov kev faib ua feem ntawm bauxite siv hauv cov khoom tsis yog xim hlau yog me me, nws muaj ntau yam kev siv.Piv txwv li: hais txog cov khoom siv tshuaj, sulfate, trihydrate thiab txhuas chloride tuaj yeem siv rau hauv papermaking, dej huv, ceramics thiab roj av refining;activated alumina tuaj yeem siv los ua catalyst, catalyst cab kuj thiab catalyst nyob rau hauv cov tshuaj, roj refining thiab tshuaj industries.Decolorization, dehydration, degassing, deacidification, ziab thiab lwm yam adsorbents lub cev.

Hlau aluminium yog qhov thib ob tseem ceeb tshaj plaws hlau hauv ntiaj teb, tom qab hlau.Hauv xyoo 1995, lub ntiaj teb kev noj ib tus neeg tau nce mus txog 3.29kg.Vim nws lub ntiajteb txawj nqus me me, zoo hluav taws xob thiab thermal conductivity, yooj yim machining thiab ntau lwm yam zoo heev, txhuas yog dav siv nyob rau hauv ntau yam sectors ntawm lub teb chaws kev khwv nyiaj txiag.Tam sim no, lub ntiaj teb kev siv txhuas loj tshaj plaws yog nyob rau hauv kev tsim kho, kev thauj mus los thiab ntim khoom, suav txog ntau dua 60% ntawm tag nrho cov khoom siv txhuas.Aluminium yog ib qho khoom siv tsis tseem ceeb rau kev lag luam hluav taws xob, kev lag luam dav hlau tsim, kev lag luam tshuab thiab cov khoom siv pej xeem.
