1. Kev piav qhia txog cov khoom boehmite uas tau npaj tseg: Cov khoom no tsis muaj tshuaj lom, tsis muaj saj thiab tsis muaj ntxhiab. Cov khoom ntub yog cov colloid dawb thiab cov hmoov qhuav yog cov hmoov dawb. Qhov faib tawm ntawm qhov pore yog sib xws, qhov ntim loj thiab kev nqus dej zoo. Nws muaj qhov huv radial siab, kev ua haujlwm zoo molding thiab cov khoom thixotropic gel. Cov khoom muaj kev sib kis zoo, yooj yim yaj hauv cov kua qaub thiab alkali muaj zog, thiab muaj kev ua haujlwm zoo molding.
2. Ntim thiab khaws cia pseudo boehmite: pseudo boehmite tau ntim rau hauv cov hnab woven. Khaws cia rau hauv qhov chaw txias, cua zoo thiab qhuav.
3. Cov kev siv tseem ceeb ntawm cov boehmite uas tau npaj tseg:
Cov khoom no feem ntau yog siv ua cov khoom siv raw ntawm catalyst txhawb nqa alumina ua haujlwm, xws li cov khoom siv raw ntawm hydrogenation catalyst, kev txhawb nqa ntawm hydrogenation catalyst thiab oxychlorination catalyst.
Nws kuj tseem siv tau ua molding binder rau zeolite thiab silicate refractory fiber cov khoom, xws li binder rau semi synthetic rare earth Y zeolite cracking catalyst.
Cov khoom no yog ib yam khoom siv zoo rau kev tsim ntau yam ntsev txhuas. Tom qab molding, nws tuaj yeem siv ua desiccant, adsorbent thiab catalyst carrier nrog ntau yam duab.
1. Kev xaiv cov khoom siv ua haujlwm zoo tshaj plaws thiab kev ntxuav thiab lim dej nrog lub tshuab lim dej siv lub tshuab nqus tsev uas ua haujlwm tau zoo yog qhov tseem ceeb los txo cov dej tshiab siv hauv kev tsim cov pseudo boehmite.
2. Cov tshuaj ntxuav thib peb yog siv rau kev sib xyaw cov tshuaj sodium aluminate kom txo qhov kev hloov pauv sab nraud thiab txhim kho kev siv dej tshiab kom zoo. Nws yog ib qho tseem ceeb los txo kev siv dej tshiab.
3. Txoj kev tseem ceeb los txo qhov kev siv dej tshiab yog kom nce qhov kub ntawm kev ntxuav dej kub, tsim kom muaj cov txheej txheem tsim nyog thiab txais yuav cov txheej txheem txias sib cais.
Pseudo boehmite yog ib hom pseudo boehmite nrog cov khoom siv crystallization colloidal tsis tiav. Cov khoom 1, tsis muaj tshuaj lom, 2, tsis muaj saj, 3, tsis muaj ntxhiab, 4, crystalline theem siab purity, 5, solubility zoo, 6, muaj zog adhesion, 7, nrog thixotropic gel yam ntxwv. Pseudo boehmite tuaj yeem siv dav hauv petrochemical, tshuaj chiv, silicate khoom, kev tiv thaiv ib puag ncig thiab lwm yam lag luam.
