Tsanangudzo Pfupi

White Fused Alumina ndeyekuchena kwepamusoro, synthetic mineral.

Iyo inogadzirwa nekusanganiswa kweinodzorwa yemhando yakachena giredhi Bayer Alumina muchoto chemagetsi arc pane tembiricha yakakura kupfuura 2000˚C inoteverwa neinononoka yekusimbisa maitiro.

Kudzora kwakasimba pamusoro pemhando yezvakagadzirwa uye fusion paramita inovimbisa zvigadzirwa zvekuchena kwepamusoro uye kuchena kwepamusoro.

Iyo yakatonhodzwa crude inowedzerwa kupwanywa, kucheneswa kusvibiswa kwemagineti mune yakanyanya kusimba magineti separators uye inoiswa muzvikamu zvakatetepa saizi kuti ienderane nekupera kushandiswa.

Raw Material Uye Maitiro Ekugadzira

White Fused Alumina ndeyekuchena kwepamusoro, synthetic mineral.

Iyo inogadzirwa nekusanganiswa kweinodzorwa yemhando yakachena giredhi Bayer Alumina muchoto chemagetsi arc pane tembiricha yakakura kupfuura 2000˚C inoteverwa neinononoka yekusimbisa maitiro.

Kudzora kwakasimba pamusoro pemhando yezvakagadzirwa uye fusion paramita inovimbisa zvigadzirwa zvekuchena kwepamusoro uye kuchena kwepamusoro.

Application

Mitsetse yakatsaurirwa inogadzira zvigadzirwa zvekushandisa kwakasiyana.

White Fused Alumina inobatikana zvakanyanya uye nekudaro inoshandiswa muVitrified Bonded Abrasives zvigadzirwa uko inotonhorera, nekukurumidza kucheka chiito kwakakosha uye zvakare mukugadzira yakakwira kuchena kweAlumina refractories.Zvimwe zvinoshandiswa zvinosanganisira kushandiswa muCoated Abrasives, Surface treatment, Ceramic Tiles, Anti-Skid Paints, Fluidized Bed Furnaces uye Ganda / Dental Care.
