Qhia luv luv

Sintered Mullite yog xaiv lub ntuj zoo bauxite, los ntawm ntau theem homogenization, calcined ntawm tshaj 1750 ℃. Nws yog tus cwj pwm los ntawm cov khoom loj, ruaj khov zoo thermal poob siab tsis kam, qis qis ntawm qhov kub thiab txias creep thiab zoo tshuaj corrosion kuj ua haujlwm thiab lwm yam.

Tsis tshua muaj heev nyob rau hauv nws daim ntawv ntuj, mullite yog artificially tsim rau kev lag luam los ntawm melting los yog firing ntau alumino-silicates. Qhov zoo tshaj plaws thermo-mechanical zog thiab kev ruaj ntseg ntawm cov khoom hluavtaws mullite ua rau nws yog ib qho tseem ceeb hauv ntau daim ntawv thov refractory thiab foundry.

Txawm hais tias mullite muaj raws li cov ntxhia hauv ntuj, qhov tshwm sim hauv qhov xwm txheej yog qhov tsawg heev.

Kev lag luam cia siab rau cov khoom siv hluavtaws uas ua tiav los ntawm melting lossis 'calcining' ntau yam alumino-silicates xws li kaolin, av nplaum, tsis tshua muaj andalusite lossis nplua silica thiab alumina kom kub.

Ib qho zoo tshaj plaws ntuj qhov chaw ntawm mullite yog kaolin (raws li kaolinic av nplaum). Nws yog qhov zoo tshaj plaws rau kev tsim cov refractories xws li raug rho tawm haujlwm lossis tsis muaj hluav taws kub, castables thiab cov yas sib tov.

Sintered mullite thiab fused mullite feem ntau yog siv rau kev tsim cov refractories thiab casting steel thiab titanium alloys.
