Usage
Chimwe chezvakakosha zvealumina yedu yakamiswa chimiro chayo chakatenderera, icho chinosimudzira kushanda kwayo sekumanikidza swing mafuta adsorbent. Aya machena porous particles ane yunifomu saizi uye yakatsetseka pamusoro peiyo optimal adsorption uye kusefa. Iyo yakakwira mechanical simba yealumina yakashongedzwa inovimbisa kuti inochengeta chimiro chayo chepakutanga kunyangwe mushure mekutora mvura, isina kuzvimba kana kuputika. Izvi zvinovimbisa hupenyu hwayo hurefu uye kusimba mumashandisirwo akasiyana siyana.
Chimwe chinhu chinocherechedzwa cheakamisikidzwa alumina ndeye yakasimba hygroscopicity, iyo inogonesa kuti inyatso kubvisa trace mvura mamorekuru. Izvi zvinoita kuti ive yakanyanya kushanda desiccant, kunyanya mumashandisirwo apo kuomeswa kwakadzika kunodiwa. Activated alumina zvakare isiri-chepfu, haina kuravira, isinganyungudika mumvura uye ethanol, inova nechokwadi chekuchengetedza kwayo munzvimbo dzakasiyana. Kugadzikana kwayo kwakanakisa kwekushisa kunochengetedza kuita kwakafanana kunyangwe kune tembiricha yakakwira.
Pamusoro pezvo, yedu yakabatidzwa alumina yakagadzirirwa kuti ienderane neasina kupisa ekuvandudza mayunitsi, ichipa inodhura-inoshanda mhinduro yekuenderera mberi kushandiswa. Ichi chimiro chinoita kuti ive sarudzo inogoneka uye yakavimbika kune maindasitiri akadai seoiri uye gasi, petrochemical, mishonga, nezvimwe. Kunyangwe mushure mekushandisa kakawanda, inochengetedza chimiro chayo chepakutanga uye kuita, kuve nechokwadi chekuenderana uye kuvimbika mukusefa.
Mukupedzisa, activated alumina imhinduro inoshanda uye inoshanda zvakasiyana-siyana kune zvinokonzeresa uye zvinotsigira zvinotsigira mumakemikari kuita. Iine hombe yayo yakananga nzvimbo, yakanakisa kugadzikana kwemafuta uye yakasimba adsorption kuita, isarudzo yakakwana kune yakafaranuka yekushandiswa. Yayo spherical chimiro, yakakwira mechanical simba uye hygroscopicity inoita kuti ive inoshanda yekumanikidza inozunguza mafuta adsorbent, yakanakira kuomesa kwakadzika uye kusefa. Vimba nealumina yedu yakashongedzwa kuti isangane nezvido zveindasitiri yako uye unzwe simba remhando yepamusoro catalytic zvinhu.
