Sintered Mullite

Mullite ibhinari komboni iripo yakadzikama pasi pekumanikidzwa kwakajairwa muAl2O3-SiO2 binary system. Mushonga wemakemikari ndeye 3Al2O3-2SiO2, uye theoretical composition is: Al2O3 71.8%, SiO2 28.2%. Kana ichienzaniswa neyakasikwa mullite*, mullite inowanzo shandiswa inogadzirwa zvisirizvo, kusanganisira sintered mullite uye yakasanganiswa mullite.

Synthetic mullite ndeyemhando yepamusoro refractory raw material. Iyo ine hunhu hwekuwedzera yunifomu, yakanakisa kupisa kwekuvhundutsa kugadzikana, yakakwira kuremerwa nzvimbo, diki tembiricha inokwira kukosha, kuomarara kwakanyanya, uye yakanaka makemikari corrosion kuramba.

Nzira yekugadzira uye nzira ye sintered mullite:

Sintered mullite inogadzirwa neyemhando yepamusoro bauxite yechisikigo seyakabikwa, uye inosiirwa mumoto unopisa unotenderera pamusoro pe1750 ℃ ​​kuburikidza nesarudzo maitiro uye akawanda-level homogenization.

Maitiro ekuita uye mashandisirwo e sintered mullite:

Sintered mullite ine hunhu hwemhando yepamusoro, hombe kuwanda kwehuwandu, yakanaka yekupisa kugadzikana kugadzikana, diki tembiricha inokwira kukosha uye yakanaka makemikari kuramba, uye kunaka kwayo kwakagadzikana. Panguva imwecheteyo, sintered mullite ndiko kugadzirwa kwemhando dzakasiyana uye kusava nechokwadi. Ideal raw material for refractory materials, sanitary ware blanks, precision casting nezvimwe zvigadzirwa.

Iwo emakemikari emuviri uye emakemikari indexes ye sintered mullite:
