Mhedziso yealumina yakagadziriswa
Activated alumina, inonziwo activated bauxite, inonzi activated alumina muChirungu. Alumina inoshandiswa mumagetsi inowanzonzi "activated alumina". Iyo ine porous, yakapararira zvakanyanya yakasimba zvinhu zvine nzvimbo yakakura. Iyo microporous surface ine hunhu hunodiwa pakuita catalysis, senge adsorption performance, pamusoro pekuita, yakanakisa kugadzikana kwemafuta, nezvimwe, saka inoshandiswa zvakanyanya senge catalyst uye catalyst mutakuri wemakemikari kuita.
The spherical activated alumina pressure swing oil adsorbent is white spherical porous particles. Iyo yakashongedzwa alumina ine yunifomu particle saizi, yakatsetseka pamusoro, yakakwira mechanical simba, yakasimba hygroscopicity, haina kuzvimba uye kutsemuka mushure mekunyura kwemvura, uye inoramba isingachinji. Haina chepfu, haina kunhuwa, uye isinganyungudike mumvura uye ethanol.
Alumina
Haina kunyungudika mumvura uye inogona kunyungudika zvishoma nezvishoma muconcentrated sulfuric acid. Inogona kushandiswa kunatsa simbi aruminiyamu uye zvakare iri mbishi zvinhu zvekugadzira crucibles, porcelain, refractory zvinhu uye matombo anokosha ekugadzira.
Alumina inoshandiswa se adsorbent, catalyst uye catalyst carrier inonzi "activated alumina". Iyo ine maitiro e porosity, kupararira kwepamusoro uye yakakura chaiyo nzvimbo. Inoshandiswa zvakanyanya mukurapa kwemvura, petrochemical, yakanaka makemikari, biological uye mishonga minda.
Hunhu hwealuminium
1. Yakakura chaiyo nzvimbo: activated alumina ine yakakwirira chaiyo nzvimbo. Nekudzora zvine musoro iyo sintering system yealumina, yakagadziriswa alumina ine chaiyo nzvimbo yakakwira se360m2 / G inogona kugadzirwa. Iyo yakashongedzwa alumina inogadzirwa nekushandisa colloidal aluminium hydroxide yakaora neNaAlO2 seyakabikwa ine diki diki pore saizi uye chaiyo nzvimbo yakakwira kusvika 600m2 / g.
2. Inogadziriswa pore saizi chimiro: Kazhinji kutaura, zvigadzirwa zvine saizi yepakati pore zvinogona kugadzirwa nekubheka nealuminiyamu yakachena hydroxide. Diki pore saizi zvigadzirwa zvinogona kugadzirwa nekugadzirira activated alumina ane aruminiyamu guruu, etc. nepo hombe pore saizi activated alumina anogona kugadzirira nekuwedzera zvimwe organic zvinhu, akadai ethylene glycol uye faibha, pashure combustion.
3. Iyo yepamusoro ine acidic uye ine yakanaka yekudziya kugadzikana.
Basa re activated alumina
Activated alumina ndeyechikamu chemakemikari alumina, ayo anonyanya kushandiswa se adsorbent, mvura yekuchenesa, catalyst uye catalyst mutakuri. Activated alumina ine kugona kusarudza adsorb mvura mugasi, mhute yemvura uye zvimwe zvinwiwa. Mushure mekunge iyo adsorption yazara, inogona kupiswa paanenge 175-315. D egree. Adsorption uye reactivation inogona kuitwa kakawanda.
Mukuwedzera pakushandiswa se desiccant, inogonawo kutora mafuta ekuzora kubva kune yakasvibiswa okisijeni, hydrogen, carbon dioxide, gasi rechisikigo, etc. Uye inogona kushandiswa sechinhu chinokonzera uye chinotsigira uye sechitsigiro chechromatographic analysis.
Inogona kushandiswa se defluorinating agent yemvura yekunwa yakakwira fluorine (ine yakakura defluorinating kugona), defluorinating agent yekutenderera alkanes mukugadzirwa kwealkylbenzene, deacidifying uye regenerating agent yemafuta etransformer, anoomesa mumiriri wegasi muindasitiri yekugadzira okisijeni. , indasitiri yemachira uye indasitiri yemagetsi, mumiriri wekuomesera wemhepo yezviridzwa, uye mumiriri wekuomesa uye mumiriri wekuchenesa mumakemikari fetiraiza, petrochemical drying uye mamwe maindasitiri.
