Alumina, Cov Khoom Tseem Ceeb hauv Calcined Bauxite

Calcined bauxite yog cov khoom siv ruaj khov thiab muaj ntau yam uas siv rau hauv ntau hom kev siv thoob plaws ntau yam kev lag luam. Nws yog tsim los ntawm cua sov nyoos bauxite kom tshem tawm cov dej noo thiab lwm yam impurities, uas ua rau cov khoom muaj nplua nuj nyob hauv alumina thiab tiv taus kev puas tsuaj thiab cuam tshuam.Cov khoom ntawm calcined bauxiteua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev siv abrasive blasting thiab sib tsoo daim ntaub ntawv. Nws cov tawv tawv thiab tawv tawv ua rau nws ua haujlwm zoo hauv kev tshem tawm xeb, xim, thiab lwm yam txheej txheem los ntawm cov hlau, thaum nws cov hmoov av qis ua rau nws zoo tagnrho rau kev siv hauv ib puag ncig uas tswj cov plua plav yog qhov kev txhawj xeeb tseem ceeb. Calcined bauxite kuj tau siv dav hauv kev tsim cov khoom siv refractory, uas yog siv los ua kab furnaces thiab lwm yam khoom siv txheej txheem kub. Nws cov ntsiab lus alumina siab thiab zoo heev thermal poob siab ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev siv hauv cov ntawv thov no, qhov uas nws tuaj yeem pab ua kom lub neej ntev thiab kev ntseeg siab ntawm cov khoom siv txheej txheem tseem ceeb. Ntxiv rau nwsabrasive thiab refractory khoom, calcined bauxite kuj tseem siv ntau yam ntawm lwm yam kev siv, suav nrog ua cov khoom siv hauv hydraulic fracturing, ua cov muab tub lim hauv kev tsim cov yas thiab lwm cov ntaub ntawv sib xyaw, thiab ua lub hauv paus ntawm txhuas hauv kev tsim cov tshuaj aluminium. Zuag qhia tag nrho, calcined bauxite yog cov khoom siv ntau yam nrog ntau yam khoom uas ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev siv ntau yam kev lag luam. Nws hardness, durability, thiab thermal shock kuj ua rau nws ib tug indispensable khoom nyob rau hauv abrasive thiab refractory daim ntaub ntawv, thaum nws tsis muaj plua plav thiab lwm yam khoom tshwj xeeb ua rau nws zoo tagnrho rau siv nyob rau hauv ntau yam ntawm lwm yam kev siv thiab.

Ntxiv rau nws cov kev siv tau zoo, calcined bauxite kuj yog ib qho tseem ceeb hauv kev tsim cov txhuas, uas yog cov hlau muaj txiaj ntsig zoo uas siv rau ntau yam khoom siv thiab cov khoom lag luam. Alumina, cov khoom tseem ceeb hauv calcined bauxite, yog ib qho tseem ceeb hauv kev tsim cov txhuas los ntawm electrolysis.

Aluminium yog dav siv hauv kev thauj mus los, kev tsim kho, ntim khoom, thiab ntau lwm yam lag luam. Nws lub teeb yuag thiab ntau yam khoom ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev siv ntau yam khoom, los ntawm lub tsheb thiab dav hlau mus rau cov khoom siv hauv tsev thiab ntim khoom.

Calcined bauxite plays lub luag haujlwm tseem ceeb hauv kev tsim cov txhuas los ntawm kev muab cov khoom tseem ceeb, alumina. Los ntawm kev tsim cov calcined bauxite, kev lag luam tuaj yeem tsim cov khoom siv ruaj khov thiab ntau yam uas yog qhov tseem ceeb rau kev tsim cov hlau tseem ceeb no.

Zuag qhia tag nrho, calcined bauxite yog cov khoom siv ntau yam thiab tseem ceeb uas siv ntau yam kev siv, los ntawm cov ntaub ntawv abrasive thiab refractory mus rau kev tsim cov txhuas thiab lwm yam khoom siv txhuas. Nws cov khoom ua haujlwm siab, ua haujlwm tsis zoo thiab cuam tshuam, thiab cov khoom tshwj xeeb ua rau nws yog ib qho khoom siv tsis tseem ceeb hauv ntau daim ntawv thov kev lag luam.
