Cov cheeb tsam tshwj xeeb yog hais txog tag nrho thaj tsam ntawm cov neeg nquag ib puag ncig, feem ntau qhia nyob rau hauv M² / g {} Qhov ntsuas no cuam tshuam rau cov khoom lag luam adsorption ntawm cov khoom siv:
• Feem ntau, thaj tsam tshwj xeeb ntawm cov neeg nquag muaj Alumina feem ntau yog ntawm 200 thiab 350 m² / g
• Cov khoom lag luam siab tuaj yeem ncav cuag li 400 m² / g
• Cov loj dua qhov chaw tshwj xeeb thaj tsam, qhov muaj zog dua cov adsorption muaj peev xwm feem ntau yog
Nws yuav tsum raug sau tseg tias thaj chaw loj tshwj xeeb tsis yog ib txwm zoo dua {}} Qhov kev sib npaug ntau dhau ntawm cov xwm txheej tshwj xeeb .
2, Pore ntim thiab Pore loj faib: Qhov tseem ceeb ua rau txiav txim siab adsorption adventivity
Pore volume thiab Pore loj muab faib yog lwm txheej ntawm cov tsis tseem ceeb uas cuam tshuam rau kev kawm tiav ntawm cov alumina ua haujlwm:
1.} Pore pore ntim: nws yog hais txog tag nrho cov ntim ntawm ib puag ncig ntawm anticated alumina, feem ntau xws li 0}}}}}}}}}} 3 rau 0.8 cm³ / g.
2.} Pore qhov loj me faib:
o Micro pores (<2 nm): Suitable for adsorption of small molecules.
o Mesopores ({2 - 50} nm): Tshuav Tshuav Adsorption thiab Diffusion.
o Macropores (>50 nm): Pab txhawb cov khoom thauj .
Cov ntaub ntawv sib txawv muaj cov kev txwv rau cov khoom lag luam loj. Cov khoom siv micro pench tau nyiam siv rau cov roj ziab {}}
{{03. cov neeg kho tshuab lub zog: kev kawm ntawm kev pabcuam lub neej
NEEG KHO TSHUAB PYST yog qhov taw qhia tseem ceeb rau kev ntsuam xyuas cov compressive thiab hnav-resistant lub peev xwm ntawm acumina:
• Feem ntau qhia tias n / particle lossis% hnav tus nqi
• Rau cov ntawv thov muaj kev lag luam, lub zog compressive ntawm ib qho me me feem ntau yuav tsum muaj ntau dua lossis sib npaug nrog 50n
• Rau cov ntawv thov sib nraus, nws tseem siab dua, feem ntau xav tau ntau dua lossis sib npaug rau 80n
• Rau cov ntawv thov pw kom zoo, kev saib xyuas yuav tsum tau them rau cov hnav coj mus rau tus nqi, feem ntau xav tau <1%
Tsis txaus siv tshuab zog tuaj yeem ua rau pulverization, nce siab poob siab, thiab kev pabcuam luv luv .
4.} adsorpt muaj peev xwm: Cov ntaub ntawv thov kev ua tau zoo
Adsorption muaj peev xwm hais txog qhov ntau ntawm cov tshuaj uas ib pawg loj ntawm cov neeg muaj zog Alumina tuaj yeem adsorb raws li kev mob tshwj xeeb:
• Muaj peev xwm zoo li qub
• Muaj peev xwm ua tiav muaj peev xwm: ntsuas raws li kev ua haujlwm tiag tiag, uas yog ntau dua rau kev siv
• Cov ntawv thov sib txawv tsom rau cov qauv sib txawv:
o Cov roj kom qhuav tsom rau kev ua kom muaj peev xwm
o Kev kho dej tsom rau kev ua adsorption muaj peev xwm ntawm fluorine, arsenic, thiab lwm yam .
5.}}}}}}}}} purity furosition thiab purity: cuam tshuam rau kev ruaj khov thiab xaiv
Cov tshuaj lom neeg muaj kuab lom ntawm Active Alumina muaj qhov cuam tshuam tseem ceeb rau nws qhov kev ua tau zoo:
{{01. al₂o₃ cov ntsiab lus: feem ntau nyob rau thaj tsam ntawm90-99}%, lub siab dua cov kev ua tau zoo
{{0 {}} Cov ntsiab lus Ipurity:
o Na₂o cov ntsiab lus cuam tshuam thermal ruaj khov (<0.5% is ideal)
o Fe₂o₃, sitio₂, thiab lwm yam . muaj cuam tshuam catalytictic kev ua haujlwm
{3.}}}} Cov Khoom Siv Tau Hloov Kho: qee cov ntawv thov yuav ntxiv cov khoom sib txawv los txhim kho kev ua tau zoo
6.} lwm cov ntsuas tseem ceeb
{{01. bulk ntom ntom: cuam tshuam rau filling ntim thiab siab poob
2. ps nqi: nto acidity thiab me ntsis cuam tshuam rau qee cov txheej txheem adsorption
