White corundum profile jecha capacitive alumina refractory tripartite crystal system
White corundum
Ndeipi nzira huru yewhite corundum saizi saizi jecha rinoshandiswa kupukuta zvinhu?
White corundum yakakamurwa kuita chena corundum block, chena corundum chikamu jecha, chena corundum zviyo saizi jecha uye hupfu hwakatsetseka.
Iyo white corundum chikamu jecha inogadzirwa nekushandisa yakakwirira-yepamusoro white corundum blocks kuburikidza nemaitiro akasiyana-siyana akadai sekupwanya, kuumba uye kuongorora.Iyo white corundum chikamu jecha ine maitiro easidhi uye alkali corrosion resistance uye yakakwirira kuoma.
Zvimiro: zvichena, zvakaoma uye zvakanyanya brittle kupfuura brown corundum, simba rekucheka rakasimba, kugadzikana kwakanaka kwemakemikari, uye kuvharidzira kwakanaka.Iine maitiro ekuchena kwepamusoro, kuomarara kwakanaka, uye yakasimba kupfeka kuramba, saka inowanzoshandiswa seabrasive, uye inoshandiswawo kune yakanaka uye kukuya simbi isina tsvina nezvimwe zvinhu.
Kemikari indexes yewhite corundum
| Chemical composition | AL2O3% | SiO2% | Fe2o3% | Na2O% | LOI% | Volume densityg/cm3 |
| Chena corundum index | ≥99.5% | ≤0.1% | ≤0.1% | ≤0.35% | 0.1 | 3.50 |
| White corundum powder | ≥99.5% | ≤0.1% | ≤0.1% | ≤0.35% | 0.1 | 3.50 |
White corundum inogadzirwa nemhando yepamusoro alumina poda, uye tembiricha yekunyunguduka inodarika 2000 madhigirii.Iyo ine kuchena kwepamusoro, yakanaka yekuzvirodza, asidhi uye alkali corrosion resistance, yakakwirira tembiricha kuramba uye kugadzikana kwemafuta kuita.Kuomarara kwacho kwakakwira zvishoma pane kuya kwebrown corundum, uye kuoma kwacho kwakadzikira zvishoma pane yebrown corundum.Kuomarara kwepamusoro, kukwirira kwechikamu, kutenderera kwakanaka kwechikamu chimwe chete, ruvara: chena, pasina kusvibiswa, kuve nechokwadi cheruvara uye kujeka kweiyo inopfeka-inodzivirira dhizaini kana kupfeka-inodzivirira pepa, yunifomu particle size kugovera, chimiro chakafanana chechikamu chimwe chete, chine iyo diki inogoneka yakanyanya Abrasion kuramba.
1. Liquid polishing: Liquid polishing inobva pakukwirira-kumhanya kwemvura uye kuputika kwepamusoro pebasa rekushanda nemuchena corundum grit kuti uwane chinangwa chekutsvaira.
Nzira dzinowanzoshandiswa ndeidzi: diamond jecha spraying processing, fluid dynamic grinding processing.Fluid dynamic kugaya inofambiswa ne hydraulically, ichibvumira iyo mvura yepakati inotakura chena corundum abrasive particles kuti iyerere ichidzoka nekudzoka nekumhanya kwakanyanya pamusoro peiyo workpiece kuburikidza nepfuti yejecha.Iyo yemvura yepakati inonyanya kugadzirwa nemakomisheni akakosha, ine mvura yakanaka pasi pekumanikidzwa kwakaderera, uye inosanganiswa newhite corundum poda.
2. Mechanical polishing: Mechanical polishing inoreva nzira yekupukuta inobvisa chikamu che convex chechinhu chekupukuta kubva pakugadzirisa kwepurasitiki kwenzvimbo yekucheka.Kazhinji kutaura, firimu rekupukuta rinonyanya kugadzirwa nemaoko.Zvikamu zvakakosha senge zvinotenderera zvinokwanisa kushandisa maturusi ekubatsira senge maturntable, uye kupenya kwepamusoro-soro kunogona kushandisa nzira dzemhando yepamusoro dzekupolisha.
3. Chemical polishing: Chemical polishing inoita kuti micro-protruding part of the material surface is soluble in the chemical medium than the concave surface, kuitira kuti iwane nzvimbo yakatsetseka.Mukana mukuru weiyi nzira ndeyekuti inokwanisa kupurudzira maworkpieces ane maumbirwo akaomarara pasina midziyo yakaoma, uye inokwanisa kupuruzira akawanda maworkpiece panguva imwe chete, uye kushanda zvakanaka kwakakwira.
4. Magnetic grinding and polishing: Magnetic green silicon carbide inoshandiswa kune magineti kugaya nekupukuta kuita jecha rewhite corundum pasi pechiito chemagnetic field.Iyo nzira ine zvakanakira zvekugadzirisa zvakanyanya, hutano hwakanaka, nyore kudzora mamiriro ekugadzirisa uye mamiriro ekushanda akanaka.
