Tsanangudzo Pfupi

Tabular Alumina chinhu chakachena chakasimwa pane super - tembiricha yakakwira isina MgO neB2O3 zvinowedzera, Yayo microstructure ndeye maviri - dimensional polycrystalline chimiro chine -yakakura yakakura tabular α - Al2O3 makristasi.Tabular Alumina ine yakawanda maduku maduku akavharwa pores in individval crystal , Al2O3 content inopfuura 99% .Saka ine yakanaka vhoriyamu kugadzikana uye thermal shock resistance, kuchena kwepamusoro uye refractoriness, simba rakanakisisa remagetsi, abrasion resistance against slag nezvimwe zvinhu.

Tabular uye mamwe maAggregates

Aggregates ndiwo musana wekuumbwa kwerefractory uye inopa kugadzikana kwedimensional kune zvigadzirwa zvinoramba.Iwo akaomesesa mafraction anowedzera kupisa kutyisa uye kuomarara kuramba uye mafiindi akaunganidzwa anokwirisa kugovera saizi yechikamu uye anowedzera kuramba kwechigadzirwa.

Unhu hunopindirana hweTabular alumina ndiyo mhedzisiro yeinodzorwa zvakanaka sinter process ine kupisa kwekushisa kunopfuura 1800 ° C. Kushandiswa kwekushisa kwekushisa kwepamusoro nehunyanzvi hwemazuva ano kunobvumira densification yezvinhu zvakasarudzwa zvakasvibirira pasina sintering aids iyo yaizoita. zvinokanganisa zvakanyanya kupisa kwekushisa kweiyo refractories.

Nekuda kweiyo sinter process, iwo akaunganidzwa anoratidza yakafanana mineralogical uye makemikari kuumbwa kwezvikamu zvese.Kupesana nezvigadzirwa zvakasanganiswa apo tsvina inoungana mufaindi, kushandiswa kwe sintered aggregates mukugadzira refractory kunovimbisa kugadzikana uye kuvimbika maitiro.

Junsheng inopa masaizi akasiyana-siyana ezvikamu kubva kune zvakakasharara kusvika kune akatsetseka-pasi saizi ye <45 μm uye <20 μm.Kupwanya uye kugaya kunoteverwa neyakaomesesa de-ironing matanho anokonzeresa yakaderera yemahara iron mukati mezvikamu zvakasiyana.

Kugadzira Maitiro eTabular alumina

Kushandiswa kweTabular Alumina

Tabular Alumina ndicho chinhu chesarudzo mune isina kuumbwa yakakwira performance refractories inoshandiswa mumaindasitiri akasiyana siyana anosanganisira simbi , foundry , simende , girazi , prtrochemical , ceramic , uye tsvina incineration .Zvimwe zvakajairika zvisiri-refractory application zvinosanganisira kushandiswa kwayo muchoto fenicha uye nekusefa kwesimbi.
