Dab tsi yog yam uas cuam tshuam rau qhov hnyav ntawm mullite refractory cib?

Lub ib thooj ceev index ntawm mullite refractory bricks yog ib tug kev rog xav txog ntawm lub qhov hws ntim thiab mineral muaj pes tsawg leeg ntawm mullite bricks. Nyob rau hauv ntau lawm, txij li thaum lub degree ntawm sintering ntawm mullite bricks yog ib qho yooj yim los txiav txim, nws yog feem ntau siv raws li ib txoj kev los txiav txim lub degree ntawm sintering. Muaj ob yam uas cuam tshuam qhov hnyav ntawm mullite refractory bricks:

1. Qhov ntau ntom ntawm alumina cov ntsiab lus thiab alumina particle loj ntawm mullite cib;

2. Kev tswj cov txheej txheem ntau lawm. Yog li ntawd, nyob rau hauv zus tau tej cov mullite refractory bricks, cov qib ntawm raw cov ntaub ntawv yuav tsum nruj me ntsis xaiv los tswj cov particle loj. Nyob rau hauv cov txheej txheem ntau lawm, lub siab ntawm cib xovxwm ntawm lub cib xovxwm yuav tsum tau tswj, thiab firing ntawm mullite refractory bricks yuav tsum tau tswj kom tsim nyog.

Paub qhov ceev ntawm refractory bricks yuav pab tau peb to taub seb puas mullite bricks yog tuab, thiab to taub qhov hnyav ntawm mullite cib los ntawm sab yuav pab tau peb yuav refractory cib.
