Alumina akawanikwa aripo angangoita 8 fomu, iwo α- Al2O3, θ-Al2O3, γ- Al2O3, δ- Al2O3, η- Al2O3, χ- Al2O3, κ- Al2O3 uye ρ- Al2O3, iwo akasiyana macroscopic maumbirwo emhando dzakasiyana. Gamma activated alumina icubic padhuze packed crystal, isinganyunguriki mumvura, asi inonyungudika muasidhi uye alkali. Gamma activated alumina haina simba acidic tsigiro, ine yakakwira kunyungudika 2050 ℃, alumina gel mune hydrate fomu inogona kugadzirwa muokisidhi ine yakakwira porosity uye yakakwirira chaiyo nzvimbo, ine nhanho dzekuchinja mune yakakura tembiricha renji. Pakupisa kwepamusoro, nekuda kwekupera mvura mumuviri uye dehydroxylation, iyo Al2O3surface inoratidzika kurongeka unsaturated oxygen (alkali centre) nealuminium (acid centre), ine catalytic chiitiko. Naizvozvo, alumina inogona kushandiswa semutakuri, catalyst uye cocatalyst.Gamma activated alumina inogona kuva hupfu, granules, mitsetse kana zvimwe. Tinogona kuita sekuda kwako.γ-Al2O3, yainzi "activated alumina", imhando ye porous high dispersion solid materials, nekuda kweiyo inogadziriswa pore chimiro, yakakura chaiyo nzvimbo, yakanaka adsorption performance, pamusoro ine zvakanakira acidity uye kugadzikana kwekupisa kwekupisa, microporous surface ine zvinodiwa zvecatalytic action, saka inova catalyst catalyst uye catalyst inova inotakura zvakanyanya. mutakuri muindasitiri yemakemikari neoiri, uye inoita basa rakakosha muoiri hydrocracking, hydrogenation refining, hydrogenation reforming, dehydrogenation reaction uye mota exhaust purification process.Gamma-Al2O3 inoshandiswa zvakanyanya secatalyst carrier nekuda kwekugadziriswa kweiyo pore chimiro uye acidity yepamusoro. Kana γ- Al2O3 inoshandiswa semutakuri, kunze kweiyo inogona kuve nemhedzisiro yekuparadzira uye kudzikamisa zvinoshanda zvinoriumba, zvakare inogona kupa asidhi alkali inoshanda muzinda, synergistic reaction ine catalytic inoshanda zvikamu. Iyo pore chimiro uye pamusoro pezvimiro zvecatalyst zvinoenderana ne γ-Al2O3 mutakuri, saka yakakwira performance carrier inogona kuwanikwa kune chaiyo catalytic reaction nekudzora zvimiro zvegamma alumina carrier.Gamma activated alumina inowanzogadzirwa neayo precursor pseudo-boehmite kuburikidza ne400 ~ 600 ℃ yakakwirira tembiricha kupera mvura mumuviri, saka iyo yepamusoro physicochemical properties inotemerwa zvakanyanya neyayo precursor pseudo-boehmite, asi kune nzira dzakawanda dzekuita pseudo-boehmite, uye akasiyana masosi e-dimmasteo3 anotungamira e-boehmisteo3 anotungamira-Al-Boehmite. Nekudaro, kune izvo zvinokonzeresa zvine zvakakosha zvinodiwa kune alumina mutakuri, kuvimba chete nekutonga kwe precursor pseudo-boehmite yakaoma kuwana, inofanirwa kutorwa kune prophase kugadzirira uye post processing kubatanidza nzira dzekugadzirisa hupfumi hwealuminium kuti isangane nezvinodiwa zvakasiyana. Kana tembiricha yakakwira kupfuura 1000 ℃ mukushandiswa, alumina inoitika inotevera shanduko yechikamu: γ→ δ→ θ→α-Al2O3, pakati pavo γ, δ, θ ari cubic padhuze packing, mutsauko unongori mukugoverwa kwealuminium ion mu tetrahedral uye octahedral, saka shanduko yechikamu ichi haikonzeri zvakanyanya. Oxygen ions mu alpha phase ane hexagonal padhuze packing, aluminium oxide particles iguva reunion, chaiyo nzvimbo yakadzikira zvakanyanya.
Storage:LDzivisa hunyoro, dzivirira kupuruzira, kukanda uye kuvhundutsa panguva yekufambisa, zvivakwa zvisinganayi mvura zvinofanirwa kuverengerwa.lInofanirwa kuchengetwa mudura rakaoma uye rine mhepo kudzivirira kusvibiswa kana unyoro.Package:Type
