Zibo Xiangrun thiab Shandong Bairui muab ntau hom alumina hlaws nrog cov kws tshaj lij pab pawg. Aumina hlaws muaj ob peb daim ntawv siv lead ua kom tau txais cov ntaub ntawv sib txawv thiab thov.
Daim ntawv cystal ntawm alumina hlaws peb tuaj yeem tsim tau:
1. γ-Al2O3 hlaws
γ-Al2O3 beadis tau los ntawm calcination ntawm boehmite ntawm qhov kub (500-750 ° C). γ alumina hlaws yog qhov siv lead ua cubic. Nws yog qhov ntxeem tau, cov khoom tawg yooj yim tawg nrog thaj chaw tshwj xeeb loj thiab ua haujlwm siab. Kev ua tau zoo adsorption. Nws tau siv dav hauv ntau yam kev lag luam ntawm cov adsorbents thiab cov neeg ua kom lub cev qhuav dej, lub tshuab ua kom lub tshuab ua pa huv; kev npaj dav hlau, riam phom, khoom siv hluav taws xob, khoom siv tshwj xeeb thiab lwm yam khoom siv zoo, siv hauv kev lag luam roj av thiab tshuaj lom neeg raws li cov khoom siv roj av (cov roj av ua kom zoo) lossis cov thauj khoom (rau cov roj av hydrogenate).
Nano-γ-Al2O3CMP (Tshuaj Txhuam Txhuam Txhuam Txhuam Txhuam Txhuam Txhuam) slurry tuaj yeem siv rau qhov nplaim nplaim ntawm txheej txheej tungsten, txhuas, tooj liab thiab lwm yam hlau thaiv cov ntaub ntawv thiab cov khoom siv zaj duab xis nyias hauv kev tsim hluav taws xob sib txuas, nrog rau cov iav kho qhov muag siab dua, quartz siv lead ua thiab ntau yam gemstone chemistry. Neeg kho tshuab polishing.
2. δ-Al2O3 hlaws
be-Al2O3 hlaws tau los ntawm calcination ntawm boehmite ntawm 800 ～ 1 050 ° C. δ alumina hlaws yog tetragonal system nrog muaj zog adsorption muaj peev xwm thiab ua haujlwm catalytic. Nws tuaj yeem siv los ua adsorbent, desiccant, catalyst thiab cab kuj.
3. η-Al2O3 hlaws
be-Al2O3 hlaws tau los ntawm calcining aluminium hydroxide ntawm Bayer lub cev ntawm 400-750 ° C ntawm tus nqi cua sov. η alumina hlaws yog cov txheej txheem siv lead ua cubic nrog qhov loj pore ntim thiab thaj chaw tshwj xeeb. Nws tsuas yog siv los ua tus nqa khoom rau lub catalyst.
4. θ-Al2O3 hlaws
be-Al2O3 hlaws tau los ntawm calcining aluminium hydroxide ntawm Bayer lub cev ntawm 900 ~ 1 100 ° C ntawm tus nqi cua sov. θ alumina hlaws yog cov kab ke monoclinic nrog cov khoom nruab nrab ntawm γ-Al2O3 thiab α-Al2O3. Feem ntau nyob ua ke nrog γ-Al 2 O 3 thiab α-Al 2 O 3.
5 κ-Al2O3 hlaws
be-Al2O3 hlaws tau los ntawm calcination ntawm gibbsite ntawm 800 ~ 1 150 ° C ntawm tus nqi cua sov. be-Al2O3 hlaws yog qhov hexagonal system. Cov ntawv thov tseem ceeb yog cov khoom siv hluav taws xob, cov nplais, cov nqus dej, thiab cov zoo li no.
6 ρ-Al2O3
Al-Al2O3 tau los ntawm lub cev qhuav dej ntawm gibbsite tsawg dua 75 μm nyob rau hauv lub tshuab nqus tsev tsawg dua 2.66 Pa. Al-Al2O3 tau siv dav hauv qib siab cov khoom siv hluav taws xob xws li corundum, high-aluminium, thiab aluminium-magnesium, xws li hlau ua, hlau ua, hlau tsis muaj hlau yaj, thiab kub rauv tawg. Tsis tas li ntawd, nws kuj tseem siv dav hauv txheej txheej ceramic, cov khoom siv catalyst, adsorbents thiab cov zoo li.
7. χ-Al2O3 hlaws
be-Al2O3 hlaws tau los ntawm calcination ntawm gibbsite tsawg dua 75μm nyob rau hauv qhov kev txiav txim ntawm kev tiv thaiv roj ntawm 500 ～ 750 ° C. χ-Al2O3 feem ntau yog siv kom qhuav thiab lub cev qhuav dej ntawm huab cua, roj av thiab roj av tawg. Cov catalyst tshwj xeeb rau kev tsim cov hydrogen peroxide, dechlorination ntawm cov nplaum khov, txhawb nqa catalyst, cais huab cua thiab tsim cov pa.
