Dab tsi yog High -Purity Pseudo Boehmite?
Siab -purity pseudo boehmiteyog tsim los siv siab -cov ntaub ntawv purity thiab nruj kev tsim khoom. Nws nta cov ntsiab lus qis impurity, siab dua crystal uniformity, thiab ruaj khov dua lub cev thiab tshuaj lom neeg. Nws yog feem ntau siv nyob rau hauv kev lag luam uas yuav tsum tau siab rau cov khoom purity thiab kev ua tau zoo, xws li petrochemical catalysts, zoo tshuaj, lithium roj teeb cov ntaub ntawv, thiab high-kawg alumina khoom.
Standard pseudo boehmite feem ntau yog siv rau cov pa catalyst kev txhawb nqa, cov ntaub ntawv ceramic, thiab cov khoom lag luam alumina dav dav, qhov twg impurity tswj yuav tsum tau nruj me ntsis.
Qhov Tseem Ceeb Qhov Sib Txawv Ntawm Siab -Purity thiab Standard Pseudo Boehmite
1. Tshuaj Purity
High -purity pseudo boehmite muaj alumina ntau dua (Al₂O₃) cov ntsiab lus thaum tswj nruj tswj cov impurities xws li hlau, sodium, thiab silicon.
Hauv qhov sib piv, cov khoom lag luam tuaj yeem ua tau raws li cov kev xav tau dav dav hauv kev lag luam tab sis muaj cov qib impurity siab dua, uas tuaj yeem cuam tshuam kev ua haujlwm ntawm cov khoom siv hluav taws xob qis lossis cov khoom siv alumina.
2. Cov ntsiab lus tsis huv
High-cov khoom purity feem ntau muaj:
Lower Na₂O cov ntsiab lus
Cov ntsiab lus qis dua Fe₂O₃
Tsawg SiO₂ cov ntsiab lus
Tsawg impurity theem tsis tsuas yog txo qhov kev pheej hmoo ntawm catalyst lom tab sis kuj txhim kho catalyst kev ua si, xaiv, thiab thermal stability.
3. Qhov chaw tshwj xeeb thiab qhov pore
High-purity pseudo boehmite feem ntau yog tsim los siv cov txheej txheem ntau dua los tswj cov kev loj hlob siv lead ua, uas ua rau:
Siab dua qhov chaw tshwj xeeb
Ntau yam pore loj faib
Loj pore ntim
Zoo dua dispersibility
Cov yam ntxwv no ua rau muaj kev ua tau zoo ntawm -gamma alumina ( -Al₂O₃) thiab kev txhawb nqa catalyst.
4. Kev ua tau zoo
Siab -purity pseudo boehmite feem ntau muab cov peptization zoo dua thiab tsim cov khoom. Thaum extrusion, pelletizing, thiab tshuaj tsuag kom qhuav, nws yooj yim dua kom ua tiav:
Kev siv zog ntau dua
Tsawg tawg tus nqi
Ntau yam particle qauv
Yog li ntawd, nws yog qhov tsim nyog rau siab -kawg catalyst ntau lawm.
5. Kev ua tau zoo tom qab Calcination
Tom qab calcination, siab -purity pseudo boehmite cov ntaub ntawv gamma alumina ( -Al₂O₃) nrog ib tug ntau yam siv lead ua theem. Hauv kev sib piv, calcined tus qauv pseudo boehmite feem ntau ua tau raws li qhov yuav tsum tau ua ntawm cov ntawv thov kev lag luam ib txwm muaj tab sis qhia qee qhov kev txwv hauv siab -kawg catalytic applications.
Yuav Ua Li Cas Xaiv Txoj Cai Pseudo Boehmite?
Thaum xaiv ib yam khoom, nws raug nquahu kom ua tib zoo mloog rau cov hauv qab no tsis:
Al₂O₃ purity
Na₂O, Fe₂O₃, thiab SiO₂ impurity cov ntsiab lus
Qhov chaw tshwj xeeb
Pore ntim thiab pore loj faib
Peptization kev ua haujlwm
Tsim muaj zog
Yog hais tias cov khoom yog npaj rau siab -kev ua tau zoo catalysts, siab -purity alumina, los yog tshiab zog cov ntaub ntawv, siab -purity pseudo boehmite yog pom zoo. Rau cov ntawv thov kev lag luam dav dav, tus qauv pseudo boehmite feem ntau yog txaus thiab muab cov nqi zoo dua.
Zibo Xiangrun muabpseudo boehmitecov khoom nyob rau hauv ib tug ntau yam ntawm specifications thiab yuav customize purity, tshwj xeeb nto cheeb tsam, pore ntim, thiab particle loj raws li cov neeg yuav tsum tau. Peb cov khoom muaj cov purity siab, tsis muaj impurity cov ntsiab lus, zoo heev peptization kev ua tau zoo, thiab ruaj khov tsim cov khoom. Lawv tau siv dav hauv kev txhawb nqa catalyst, gamma alumina, petrochemical catalysts, ib puag ncig catalysts, thiab cov khoom siv hluav taws xob tshiab, muab cov neeg siv khoom txhim khu kev qha thiab zoo sib xws raw khoom daws teeb meem.
