Alumina Powder/α-Alumina Micropowder
Tsanangudzo
Alumina poda chinhu chisingaoneki chine makemikari formula Al2O3.Ikomboni yekuomarara kwepamusoro ine kunyunguduka kwe2054°C uye kuvira kwe2980°C.Iyo ionic crystal inogona ionize pakupisa kwakanyanya uye inowanzoshandiswa mukugadzira zvinhu zvinoramba.
Alumina powder is alumina Al2O3 poda yakasimba, inowanzogadzirirwa α-al2o3 alumina powder, β-al2o3 alumina powder, γ-al2o3 alumina powder sekushandiswa kwakasiyana.
α-Alumina micropowder
α alumina poda ine yakagadzikana kwazvo yemuviri uye makemikari zvimiro, kuomarara kwepamusoro, kupfeka kuramba, kusimba kwemagetsi, kuvharisa, kushomeka kwekushisa kwakanyanya, kuderera kwekupisa, kuderera kwekuwedzera kwekupisa, kunaka kwemafuta conductivity uye mamwe maitiro.
α alumina inowanzo shandiswa seabrasive, toughening agent, refractory materials, polishing materials, etc.
Production Process
1. Raw material ball mill: inobatsira kubvisa tsvina, kuvandudza chiyero chekushandura kwekupfura, uye kuwedzera kukurumidza kuita;
2. Kugocha kwemugero: kugadzirwa kunoenderera uye kwakagadzikana kunogona kuitika, uye tembiricha yekugocha inogona kudzorwa nemazvo;
3. Clinker ball mill: Geya clinker kuita size inodiwa.

Application
1. Refractory products.High alumina bauxite clinker ine refractoriness inosvika 1780 ℃, yakasimba kemikari yakagadzikana uye yakanaka yemuviri zvinhu.
2. Precision casting.Bauxite clinker inogaya kuita poda yakatsetseka yoitwa molds kuti inyatso kukanda.Inoshandiswa muindasitiri yemauto, aerospace, kutaurirana, zviridzwa, michina nemadhipatimendi emidziyo yekurapa.
3. Aluminium industry.National kudzivirira, ndege, motokari, midziyo yemagetsi, makemikari, zvinodiwa zuva nezuva, nezvimwewo.
4. Aluminium silicate refractory fiber;shandisa magnesia uye bauxite clinker sezvimisikidzwa, jecha uye bauxite clinker seyakabikwa, jecha uye bauxite clinker seyakagadzirwa, kugadzira bauxite simende, abrasive zvinhu, ceramic indasitiri uye indasitiri yemakemikari inogona kugadzirwa Yakasiyana-siyana makomisheni ealuminium.
