Taw Qhia Ntawm Ob Hom Pseudo-boehmite Ntau Lawm Tshuab
Dec 09, 2022
Cov txheej txheem ntau lawm ntawm pseudo-boehmite feem ntau yog los ntawm nruab nrab lossis hydrolysis rau hauv gel, thiab tom qab ntawd kev laus kho, qee zaum kev laus, crystallization, kev laus thiab lwm yam tshwm sim yuav tshwm sim. Yog li dab tsi yog cov txheej txheem pseudo-boehmite ntau lawm? Thiab Xiaobian ua ke kom nkag siab nws
1, acid-base neutralization txoj kev
Cov txheej txheem neutralization siv cov khoom siv sib txawv ntawm cov khoom siv aluminium thiab cov khoom sib txuam kom tau txais cov tshuaj tiv thaiv neutralization nyob rau hauv qee yam kev mob los tsim cov khoom alumina nrog amorphous theem pib, thiab tom qab ntawd cov khoom tau txais los ntawm ntau txoj haujlwm ua haujlwm.
Carbonization yog ib yam ntawm neutralization txoj kev, uas tsis yog tsuas yog siv nyob rau hauv lub decomposition txheej txheem ntawm alumina ntau lawm los ntawm sintering txoj kev, tab sis kuj yuav siv tau los npaj pseudoboehydrite raws li tsim nyog decomposition txheej txheem thiab cov khoom tej yam kev mob. Qhov tseeb, cov txheej txheem carbonation kuj yog ib txoj hauv kev nruab nrab, qhov txawv yog tias nws yog cov txheej txheem ua kua roj los tsim cov gel. Sodium aluminate tov yog siv los ua raw khoom thiab precipitant.
Carbonization gelling txais qhov kub thiab txias, kev kub ceev, tsis muaj pH gelling txheej txheem. Cov kev hloov me me hauv qhov kub thiab txias, concentration, qhov cua qhov cua, ph nqi ntawm cov tshuaj thiab lwm yam kev tswj xyuas yuav cuam tshuam ncaj qha rau qhov zoo ntawm cov khoom gelling, kev ua haujlwm tom qab thiab cov khoom lag luam, tshwj xeeb tshaj yog cov kev qhia tseem ceeb xws li purity ntawm crystalline. theem tsim, gel dissolution Performance index, thiab gel dissolution tus nqi. Cov khoom ntawm cov gelation ceev yog feem ntau amorphous, nrog rau ib qho me me ntawm sodium bauxite compound ntsev, uas yuav tsum tau kho tom qab, xws li cov txheej txheem kev laus kom tau txais cov khoom quasi-bauxite uas ua tau raws li cov kev xav tau ntawm kev siv.
2, organic cawv ntsev txoj kev
Raws li tus yam ntxwv uas txhuas tuaj yeem tsim cov organic teeb meem, aluminium alkoxide tau npaj nyob rau hauv qee yam mob, thiab tom qab ntawd hydrolyzed kom tau pseudo-boehmite.
Piv nrog rau cov khoom tsim los ntawm lwm cov txheej txheem, cov khoom npaj los ntawm dej cawv-aluminium hydrolysis muaj qhov zoo ntawm cov tshuaj purity siab, tsawg dua lwm yam, zoo crystallinity thiab zoo gel solubility. Txawm li cas los xij, tus nqi yog kim thiab tsuas yog haum rau cov khoom. Cov pseudo-bottraite tsim los ntawm txoj kev no muaj ib tug purity txog li 5N, siab tshuaj purity, loj pore ntim, thiab loj tshwj xeeb deg cheeb tsam.
Cov saum toj no yog Zhongtianli Xiaobian los qhia tag nrho cov ntsiab lus cuam tshuam nrog koj. Koj tuaj yeem tiv tauj peb yog tias koj muaj kev xav tau tshwj xeeb. Zibo Yishengjia Aluminium Co., Ltd. yog lub chaw tsim khoom tshwj xeeb hauv kev tsim, tsim khoom thiab muag khoom ntawm nanomaterials. Peb tos ntsoov rau koj qhov kev sab laj txhua lub sijhawm.
