Cov qauv kev lag luam rau fused alumina feem ntau npog cov tshuaj muaj pes tsawg leeg, cov khoom siv lub cev, thiab cov qauv kev sim, siv los tsim cov khoom lag luam zoo thiab sib koom ua ke kev sim. Cov hauv qab no yog cov qauv tseem ceeb hauv tebchaws:
1. Cov Qauv Khoom
GB/T 24487-2020 "Alumina" Muaj feem xyuam rau alumina siv hauv kev tsim cov hlau txhuas los ntawm molten ntsev electrolysis, thiab tseem siv tau rau kev tsim cov corundum, ceramics, thiab cov ntaub ntawv refractory. Nws qhia txog cov kev txwv rau lub ntsiab Cheebtsam thiab impurities nyob rau hauv industrial-qib alumina:
Al₂O₃ Ntau dua lossis sib npaug li 98.5% (High- qib purity tuaj yeem ncav cuag Ntau dua lossis sib npaug li 99%)
Na₂O Tsawg dua lossis sib npaug li 0.5% Cov impurities xws li Fe₂O₃, SiO₂, thiab CaO tau qhia meej txog cov kev txwv saum toj kawg nkaus.
2. Cov qauv tshuaj ntsuam xyuas thiab kev txiav txim siab lub cev (GB/T 6609 Series)
Cov txheej txheem no yog tshwj xeeb rau kev kuaj cov ntaub ntawv alumina. Qee cov qauv tseem ceeb yog raws li hauv qab no:
