Cov ntaub ntawv sab hauv zoo yog qhov ua rau muaj kev ntseeg siab hauv kev lag luam - tshwj xeeb tshaj yog thaum muaj xwm txheej hnyav.Alumina cib ntsa, tsim los nrog 75–99.99% Al₂O₃ cov ntsiab lus, tau dhau los ua qhov kev xaiv mus-rau thoob plaws cov lag luam tseem ceeb, daws cov teeb meem mob uas cov kab lis kev cai ib txwm tsis tuaj yeem daws tau. Los ntawm cov cub tawg cement kub siab mus rau cov chaw tsim tshuaj lom neeg corrosive, lawv cov ntawv thov ntau yam muab cov nqi tsis sib xws qhov twg kev ua tau zoo tseem ceeb tshaj plaws. Tshawb nrhiav lawv qhov cuam tshuam hloov pauv hauv tsib lub lag luam tseem ceeb.
Kev Tsim Khoom Siv Cement
Cov qhov cub rotary thiab cov preheaters ntsib 1400°C+ kub, abrasive clinker, thiab alkaline tawm tsam. Alumina cib (85–95% Al₂O₃) muaj Mohs hardness 9 thiab siab refractoriness, tiv taus hnav thiab txo cov cua sov poob los ntawm 25–30%.
Kev khawb av thiab kev ua cov khoom siv minerals
Cov hlau, xuab zeb, thiab cov slurries ua rau cov khoom siv hlau puas tsuaj sai sai. Cov alumina liners (90%+ Al₂O₃) muab 10–20 npaug ntawm kev hnav tsis kam ntawm cov hlau manganese, zoo tagnrho rau cov kav dej, cov tshuab zeb pob, thiab cov chutes. Lawv txo kev siv cov xov xwm los ntawm 30% thiab tiv thaiv kev ua qias tuaj ntawm cov khoom, qhov tseem ceeb rau cov zaub mov ntshiab siab. Lub chaw khawb tooj liab hauv South America tau ntev lub neej ntawm cov kav dej slurry los ntawm 3 lub hlis mus rau 4 xyoos, tshem tawm cov nqi hloov pauv txhua hli thiab kev kaw tsis tau npaj tseg.
Kev Tsim Hluav Taws Xob
Cov chaw tsim hluav taws xob thermal, biomass, thiab cov chaw tsim pov tseg ua hluav taws xob xav tau cov liners uas tiv taus qhov kub siab, cov pa roj flue, thiab kev yaig ntawm cov tshauv. Cov cib alumina tiv taus 500°C+ thermal shocks thiab corrosive SOx/NOx, ua tau zoo dua li cov hlau alloy.
Kev Lag Luam Tshuaj Lom Zem thiab Petrochemical
Cov kua qaub, alkalis, thiab cov ntsev molten ua rau cov liners ib txwm puas tsuaj. Cov cib alumina ntshiab heev (99%+ Al₂O₃) tsis muaj zog, tiv taus 98% sulfuric acid thiab 50% sodium hydroxide.
Semiconductor & High-Tech
Cov cib alumina uas huv heev (99.99% Al₂O₃) ua rau muaj kev tsim khoom semiconductor uas tsis muaj kuab paug. Tsis muaj qhov porous thiab tsis ua haujlwm, lawv tiv thaiv kev tawm ntawm cov hlau ion, ua kom cov hlau wafer hauv qab 1ppm rau 7nm/5nm chips.
Hauv txhua daim ntawv thov, cov cib alumina muab kev tiv thaiv ntev thiab pheej yig uas tsav kev ua haujlwm zoo tshaj plaws. Lawv qhov kev hloov pauv rau cua sov, kev puas tsuaj, kev xeb, thiab kev ua qias tuaj ua rau lawv yog kev nqis peev ntse rau kev txo cov nqi thiab ua kom muaj txiaj ntsig zoo tshaj plaws.
Npaj txhij nrhiav koj txoj kev daws teeb meem uas haum rau koj? Peb cov kws tshaj lij yuav soj ntsuam koj cov kev xav tau—txij li cov qhov cub cement kub siab mus rau cov khoom siv semiconductor ntshiab heev—thiab xa cov ntaub alumina uas haum rau koj. Tiv tauj peb hnub no kom tau txais kev hais nqe lossis kev sab laj txog kev siv tshuab. Koj txoj kev daws teeb meem uas ruaj khov tshaj plaws hauv kev lag luam tsuas yog tham nrog koj xwb.
