Pseudoboehmite

Kuj tseem hu ua alumina monohydrate, pseudodiaspore, lub npe Askiv: Pseudo Boehmite, AlOOH·nH 2O, n= 0.08 ~ 0.62, tsis muaj tshuaj lom, tsis qab, tsis muaj ntxhiab, dawb colloid (ntub) lossis hmoov (qhuav), siv lead ua purity siab, zoo gel solubility, muaj zog adhesion, nrog rau qhov tshwj xeeb nto, loj pore ntim thiab lwm yam ntxwv, nws cov ntsiab lus dej yog thixotropy gel.

Lub luag haujlwm editor tshaj tawm

Nws tuaj yeem siv los ua cov ntawv khi rau semi-synthetic tsis tshua muaj lub ntiaj teb Y hom molecular sieve cracking catalyst, binder rau aluminium silicate refractory fiber, catalyst rau cawv dehydration los tsim ethylene thiab reoxyethane, thiab lwm yam. Nws kuj yuav siv tau raws li raw khoom rau zus tau tej cov catalyst carrier, activated alumina thiab lwm yam txhuas ntsev.

Cov txheej txheem ntau lawm editor tshaj tawm

-al2o3 calcined ntawm 400 ~ 700 degree yog dav siv los ua catalyst cab kuj, catalyst thiab adsorbent. Nano-qib -al2o3 tuaj yeem tau txais los ntawm calcination ntawm 1100 ~ 1200 degree . Nws yog dav siv raws li txheej additive, qib high-qib ceramics, high efficiency catalyst nyob rau hauv petrochemical kev lag luam, sub-micron / nano qib sib tsoo cov ntaub ntawv thiab polishing khoom, cosmetic muab tub lim thiab inorganic membrane cov ntaub ntawv, thiab lwm yam. kev vam meej.

Aluminium qhov chaw editor tshaj tawm

Tsis tas li ntawd, nws yog qhov nyiam aluminium qhov chaw rau kev sib txuas ntawm phospho-al zeolites thiab heteratomic phospho-al zeolites. Rau cov synthesis ntawm phosphorus thiab aluminium molecular sieves thiab heteratomic phosphorus thiab aluminium series molecular sieves, nws yog qhov zoo tshaj rau ntxiv phosphorus thiab txhuas qhov chaw nrog rau qhov sib ntxiv ntawm cov pa oxygen. Thiab qhov dav dav txhuas ntsev ntawm aluminium atoms tsis txuas nrog oxygen atoms, yog tias nws yog siv los ua txhuas qhov chaw, nws yog qhov nyuaj los yog txaus cov pa oxygen, yog li qhov xwm txheej dav dav tsis yog txhuas ntsev. Xav txog cov kev xav tau ntawm kev sib cais ntawm cov tshuaj tiv thaiv sib tov, aluminium qhov chaw ntxiv yog qhov zoo tshaj plaws soluble nyob rau hauv qaug zog acid los yog nruab nrab lub zog acid tov, thiab txhuas oxide los yog aluminium hydroxide tsuas yog soluble nyob rau hauv muaj zog acid los yog muaj zog alkali tov, tsis conducive rau dispersion ntawm lub tshuaj tiv thaiv sib tov, tsis haum rau txhuas qhov chaw. Pseudoboehmite yog qhov zoo tshaj plaws txhuas qhov chaw vim tias nws tuaj yeem ua tau raws li qhov yuav tsum tau muaj cov pa oxygen thiab cov tshuaj tiv thaiv sib tov sib npaug thiab tawg.
