Pseudoboehmite alumina, pseudoboehmite alumina hmoov, pseudoboehmite blinder yog ib tug dawb gel (ntub) los yog hmoov (qhuav), odorless, tasteless, non-toxic. Lub thixotropy nrog cov cim ntawm siab purity crystalline theem, zoo heev gelation thiab muaj zog caking khoom. Feem ntau yog siv los ua raw khoom rau catalyst cab kuj-activated alumina. Tsis tas li ntawd, ib qho cement rau molecular sieve thiab aluminium silicate refractory fiber, xws li cov cement rau catalyst ntawm semi-synthetic, tsis tshua muaj ntiaj teb Y molecular sieve tawg, cov cement rau catalyst hauv kev ua ethylene los ntawm dej cawv dehydration, ink receptive pigment hauv txheej thiab ua. epoxyethane. Rau cov neeg siv khoom tshwj xeeb hauv gelation, pseudoboehmite nrog gelation zoo tuaj yeem muab tau.

Pseudoboehmite yog ib qho ntawm alumina hydrates. Muaj pseudo-boehmite, pseudoboehmite, quasi-tseem hu ua monohydrate alumina, pseudoboehmite thiab lwm lub npe, AlOOH·nH 2O, n= 0. 08 ~ 0. 62, tsis muaj Poisonous, tasteless, odorless, dawb colloid (cov khoom ntub dej) los yog hmoov (cov khoom qhuav). Pseudoboehmite muaj crystallinity tsawg, cov ntsiab lus dej siab dua boehmite, thiab feem ntau muaj nyob rau hauv lub xeev colloidal. Tam sim no, txoj kev npaj ntawm pseudo-boehmite feem ntau suav nrog txhuas alkoxide hydrolysis method, acid method thiab alkali method (carbonization method). Cov kauj ruam tseem ceeb hauv kev tsim cov pseudoboehmite los ntawm hydrolysis ntawm aluminium alkoxides yog kom hnov mob hlau aluminium nrog ntau dua cawv nyob rau hauv lub xub ntiag ntawm catalysts los tsim aluminium alkoxides. Cov khoom purity ntawm aluminium cawv hydrolysis txoj kev yog siab, tab sis ib tug loj npaum li cas ntawm cov dej khib nyiab yuav tsim nyob rau hauv cov txheej txheem ntau lawm, thiab cov nqi rov qab ntawm cov organic cawv yog siab, uas ua rau tus nqi siab ntawm pseudoboehmite.

Pseudoboehmite alumina, pseudoboehmite alumina hmoov tuaj yeem siv los ua cov ntawv khi rau semi-synthetic tsis tshua muaj ntiaj teb Y-hom molecular sieve cracking catalyst, ib phau ntawv rau txhuas silicate refractory fibers, catalyst rau dej cawv rau ethylene thiab catalyst rau ethylene oxide, thiab lwm yam. , as Well as activated alumina thiab lwm yam txhuas ntsev raw cov ntaub ntawv.
