Boehmite, tseem hu ua monohydrate alumina, yog hydroxide oxide ntawm txhuas nrog cov tshuaj formula - AlOOH. Nws yog ib qho khoom nruab nrab ntawm lub cev qhuav dej ntawm aluminium hydroxide (ATH) nyob rau hauv tej yam kev mob thiab ib qho tseem ceeb precursor rau kev tsim ntawm siab - kub alumina ( - Al ₂ O3) los ntawm calcination.

Khoom nta
Nws yog qhov tshwj xeeb nrog thaj chaw siab tshwj xeeb (feem ntau txog 100-300 m ² / g lossis siab dua). Qhov no muab ntau qhov chaw ua haujlwm saum npoo av, uas yog qhov tseem ceeb rau kev hloov kho saum npoo av thiab kev sib cuam tshuam ntawm lub ntsej muag. Nws kuj yog featured nrog kev ua haujlwm siab. Qhov saum npoo yog nplua nuj nyob rau hauv hydroxyl pawg (- OH), ua kom yooj yim rau kev hloov kho saum npoo av (xws li silanization), uas ua rau nws muaj kev sib cais zoo hauv cov tshuab organic lossis ua ke nrog cov polymers. Nws muaj cov khoom siv kho tshuab zoo heev. Cov nyhuv filling ntawm nanoparticles tuaj yeem txhim kho lub zog, toughness, thiab hardness ntawm cov khoom sib xyaw. Nws muaj tus cwj pwm thermal tshwj xeeb. Cov yam ntxwv thermal decomposition ntawm boehmite yog kwv yees li 450-500 degree, nws yog ib qho hluav taws xob tsis muaj hluav taws xob halogen. Nws tseem muaj tshuaj lom neeg ruaj khov, tiv thaiv corrosion, rwb thaiv tsev, tsis muaj tshuaj lom thiab tsis muaj mob.
Khoom siv
Nws yog siv los ua cov txheej txheem tseem ceeb rau ceramic coated daim nyias nyias (CCS), boehmite txheej decomposes thiab nqus cua sov ntawm qhov kub thiab txias, thiab hloov mus rau hauv cov txheej txheej alumina, uas tuaj yeem txhim kho thermal stability ntawm cov khoom sib cais (tiv thaiv thermal shrinkage), tiv thaiv qhov zoo thiab tsis zoo electrode tiv tauj luv luv, thiab txhim khu kev ruaj ntseg ntawm lub roj teeb. Nws tuaj yeem siv rau qib siab -kawg engineering plastics (xws li PA, PBT), roj hmab tshwj xeeb, cov txheej tiv thaiv hluav taws, thiab cov khoom siv hluav taws xob. Vim nws cov nyhuv nano, nws muaj cov nplaim hluav taws xob ntau dua li cov boehmite zoo tib yam, nrog tsawg ntxiv thiab tsis tshua muaj kev cuam tshuam rau cov khoom siv kho tshuab. Nws kuj yog siv rau catalysts thiab catalyst kev txhawb nqa, qhov loj ntawm thaj chaw tshwj xeeb ua rau muaj kev cuam tshuam loj heev ntawm cov hlau muaj txiaj ntsig (xws li Pt, Pd), uas ua rau muaj txiaj ntsig zoo thiab ruaj khov catalysts. Nws yog ib tug siab - zoo precursor rau kev npaj ntawm nano alumina ( - Al2 O3, - Ib2 O3). Cov nano alumina tau tom qab calcination tuaj yeem siv rau hauv ntau qhov chaw, xws li precision polishing, advanced ceramics, pob tshab ceramics, thiab lwm yam.
