White corundum mbiri mchenga capacitive alumina refractory tripartite crystal system
White corundum
Njira yayikulu ya mchenga wa white corundum yomwe imagwiritsidwa ntchito popukuta zinthu?
White corundum imagawidwa mu white corundum block, white corundum gawo mchenga, white corundum tirigu kukula mchenga ndi ufa wabwino.
Mchenga wa gawo loyera la corundum umapangidwa pogwiritsa ntchito zida zapamwamba zoyera za corundum kudzera m'njira zosiyanasiyana monga kuphwanya, kuumba ndi kuyang'ana.Mchenga wa gawo loyera la corundum uli ndi mawonekedwe a asidi ndi alkali kukana dzimbiri komanso kulimba kwambiri.
Zowoneka: zoyera, zolimba komanso zonyezimira kuposa brown corundum, mphamvu yodulira mwamphamvu, kukhazikika kwamankhwala abwino, komanso kutchinjiriza kwabwino.Lili ndi makhalidwe a chiyero chapamwamba, kuuma kwabwino, ndi kukana kwamphamvu kuvala, choncho nthawi zambiri amagwiritsidwa ntchito ngati abrasive, komanso amagwiritsidwa ntchito bwino ndi kugaya zitsulo zosapanga dzimbiri ndi zipangizo zina.
Ma Chemical index a white corundum
| Chemical kupanga | AL2O3% | SiO2% | Fe2o3% | Na2O% | LOI% | Volume kachulukidwe/cm3 |
| Choyera corundum index | ≥99.5% | ≤0.1% | ≤0.1% | ≤0.35% | 0.1 | 3.50 |
| White corundum ufa | ≥99.5% | ≤0.1% | ≤0.1% | ≤0.35% | 0.1 | 3.50 |
White corundum imapangidwa ndi alumina ufa wapamwamba kwambiri, ndipo kutentha kosungunuka kumaposa madigiri 2000.Ili ndi chiyero chambiri, kudzinola bwino, kukana kwa asidi ndi alkali corrosion, kukana kutentha kwambiri komanso kukhazikika kwamafuta.Kuuma kwake ndikwapamwamba pang'ono kuposa kwa brown corundum, ndipo kulimba kwake kumakhala kotsika pang'ono kuposa kofiira kofiira.Mkulu kuuma, mkulu tinthu kachulukidwe, zabwino single tinthu roundness, mtundu: woyera, palibe zonyansa, kuonetsetsa mtundu ndi mawonetseredwe a kuvala zosagwira wosanjikiza kapena kuvala zosagwira pepala, yunifolomu tinthu kukula kugawa, yunifolomu mawonekedwe a tinthu limodzi, ndi ang'onoang'ono zotheka pazipita Abrasion kukana.
1. Kupukuta kwamadzimadzi: Kupukuta kwamadzimadzi kumachokera kumadzi othamanga kwambiri komanso kukokoloka kwa pamwamba pa workpiece ndi white corundum grit kuti akwaniritse cholinga cha kupukuta.
Ambiri ntchito njira ndi: diamondi mchenga kupopera processing, madzimadzi zazikulu akupera processing.Kugaya kwamadzimadzi kumayendetsedwa ndi hydraulically, kulola sing'anga yamadzi yonyamula tinthu tating'onoting'ono ta corundum abrasive particles kuyenda mmbuyo ndi mtsogolo pa liwiro lalikulu pamwamba pa workpiece kupyolera mumfuti ya sandblasting.Sing'anga yamadzimadzi imapangidwa makamaka ndi mankhwala apadera, imakhala ndi madzi abwino pansi pa kupanikizika kochepa, ndipo imasakanizidwa ndi ufa woyera wa corundum.
2. Kupukuta kwamakina: Kupukuta kwamakina kumatanthawuza njira yopukutira yomwe imachotsa gawo lopindika la zinthu zopukutira kuchokera pamapindidwe apulasitiki a malo odulira.Nthawi zambiri, filimu yopukutira imapangidwa makamaka ndi manja.Magawo apadera monga malo ozungulira amatha kugwiritsa ntchito zida zothandizira monga ma turntables, ndipo kupukuta kopitilira muyeso kungagwiritse ntchito njira zapamwamba zopukutira.
3. Kupukuta kwa mankhwala: Kupukuta kwa mankhwala kumapangitsa kuti gawo laling'ono laling'ono lazinthu likhale losungunuka kwambiri m'kati mwa mankhwala kusiyana ndi concave pamwamba, kuti mupeze malo osalala.Ubwino waukulu wa njirayi ndikuti imatha kupukuta zida zogwirira ntchito zokhala ndi mawonekedwe ovuta popanda zida zovuta, ndipo zimatha kupukuta ma workpiece angapo nthawi imodzi, ndipo magwiridwe antchito ndi apamwamba.
4. Maginito akupera ndi kupukuta: Maginito obiriwira silicon carbide amagwiritsidwa ntchito popera maginito ndi kupukuta kuti apange mchenga woyera wa corundum pansi pa mphamvu ya maginito.Njira ali ndi ubwino mkulu processing dzuwa, khalidwe labwino, kulamulira mosavuta zinthu ndondomeko ndi zinthu zabwino ntchito.
