Tsanangudzo Pfupi

Sintered Mullite inosarudzwa yemhando yepamusoro-soro bauxite, kuburikidza neakawanda-level homogenization, yakaverengerwa pamusoro pe1750 ℃.Iyo inoratidzirwa nehupamhi hwepamusoro density, yakagadzikana yemhando yekudzikama thermal shock resistance, yakaderera index yekukwira kwekushisa kwepamusoro uye yakanaka kemikari corrosion resistance performance uye zvichingodaro.

Yakanyanya kushomeka muchimiro chayo chechisikigo, mullite inogadzirwa zvekugadzira indasitiri nekunyungudusa kana kupfura akasiyana alumino-silicates.Iyo yakasarudzika thermo-mechanicha zvivakwa uye kugadzikana kweinoguma synthetic mullite inoita kuti ive chinhu chakakosha mune dzakawanda refractory uye foundry application.

Kunyangwe mullite iripo sechisikigo chicherwa, zvinoitika mumasikirwo hazviwanzo.

Iyo indasitiri inotsamira pane ekugadzira mullites ayo anowanikwa nekunyungudusa kana 'calcining' akasiyana alumino-silicates akadai se kaolin, ivhu, kashoma andalusite kana yakanaka silica uye alumina kune yakanyanya tembiricha.

Imwe yenzvimbo dzakanakisa dzemullite ndeye kaolin (se kaolinic clays).Yakanakira kugadzirwa kwemarefractories akadai seakapfurwa kana asina kupiswa zvidhinha, castables uye musanganiswa wepurasitiki.

Sintered mullite uye fused mullite inonyanya kushandiswa kugadzira refractories uye kukanda simbi uye titanium alloys.

Zvinhu zvenyama

• Good creep resistance

• Low thermal conductivity
• Kugadzikana kwakanaka kwemakemikari
• Yakanakisa thermo-mechanical kugadzikana
• Excellent thermal shock resistance
• Low porosity
• Kureruka kana kuenzaniswa
• Oxidation resistance
