Refractory calcined aluminium okusayidi ufa
Alumina Powder/α-Alumina Micropowder
Alumina ufa ndi inorganic mankhwala ndi mankhwala chilinganizo Al2O3.Ndi chinthu cholimba kwambiri chokhala ndi malo osungunuka a 2054 ° C ndi malo otentha a 2980 ° C.Ndi kristalo wa ionic womwe umatha kutentha kwambiri ndipo umagwiritsidwa ntchito nthawi zambiri popanga zinthu zokana.
Alumina ufa ndi alumina Al2O3 ufa wolimba, nthawi zambiri umagwiritsidwa ntchito α-al2o3 alumina ufa, β-al2o3 alumina ufa, γ-al2o3 alumina ufa monga ntchito yosiyana.
α-Alumina micropowder
α alumina ufa ali ndi mphamvu zokhazikika zakuthupi ndi mankhwala, kuuma kwakukulu, kukana kuvala, mphamvu zamakina apamwamba, kutsekemera, kukana kutentha kwapamwamba, kutsika kwa kutentha, kutsika kwa mphamvu yowonjezera kutentha, kutsekemera kwabwino kwa matenthedwe ndi makhalidwe ena.
α alumina nthawi zambiri amagwiritsidwa ntchito ngati abrasive, toughening agent, refractory materials, polishing materials, etc.
Njira Yopanga
Zopangira mpira mphero: kumathandiza kuchotsa zonyansa, kusintha mlingo wa kutembenuka kwa ndondomeko kuwombera, ndi kuonjezera anachita liwiro;
Kuwotcha mumphika: Kupanga kosalekeza komanso kokhazikika kumatha kuchitika, ndipo kutentha kowotcha kumatha kuyendetsedwa molondola;
Clinker mpira mphero: Pogaya clinker mu kukula chofunika tinthu.

Kugwiritsa ntchito
1. Refractory products.High alumina bauxite clinker ili ndi refractoriness mpaka 1780C, kukhazikika kwamphamvu kwa mankhwala ndi katundu wabwino wakuthupi.
2. Kuponyera mwatsatanetsatane.Clinker ya bauxite imasinthidwa kukhala ufa wabwino ndikupangidwa kuti apange zisankho kuti apange mwatsatanetsatane.Amagwiritsidwa ntchito m'mafakitale ankhondo, zakuthambo, kulumikizana, zida, makina ndi zida zamankhwala.
3. Aluminium industry.National chitetezo, ndege, magalimoto, zipangizo zamagetsi, mankhwala, zofunika tsiku ndi tsiku, etc.
4. Aluminiyamu silicate refractory CHIKWANGWANI;gwiritsani ntchito magnesia ndi bauxite clinker ngati zopangira, mchenga ndi bauxite clinker monga zopangira, mchenga ndi bauxite clinker monga zopangira, kupanga simenti ya bauxite, zinthu zowononga, mafakitale a ceramic ndi makampani opanga mankhwala akhoza kupangidwa Mitundu yosiyanasiyana ya aluminiyamu.
