Ziziphi izinto ezichaphazela ubunzima mullite izitena refractory?

Isalathiso sobuninzi bobuninzi bezitena eziphikisayo ze-mullite yimbonakaliso ebanzi yomthamo we-pore kunye nokubunjwa kwamaminerali kwizitena ze-mullite. Kwimveliso, ekubeni i-degree of sintering yezitena ze-mullite kulula ukuyiqonda, isoloko isetyenziswa njengendlela yokugweba iqondo le-sintering. Kukho izinto ezimbini ezichaphazela ubunzima bezitena ze-mullite refractory:

1. Ubuninzi be-alumina content kunye ne-alumina particle size of mullite bricks;

2. Ukulawulwa kwenkqubo yokuvelisa. Ngoko ke, ekuveliseni izitena ze-mullite refractory, amabakala ezinto eziluhlaza kufuneka akhethwe ngokungqongqo ukulawula ubungakanani be-particle. Kwinkqubo yokuvelisa, uxinzelelo lwesitena sokushicilela izitena kufuneka ilawulwe, kwaye ukudubula kwezitena eziphikisayo ze-mullite kufuneka kulawulwe ngokufanelekileyo.

Ukwazi ukuxinana kwezitena eziphikisayo kungasinceda ukuba siqonde ukuba ingaba izitena ze-mullite zixinene, kwaye ukuqonda ubunzima bezitena ze-mullite ukusuka ecaleni kungasinceda ukuba sithenge izitena ze-refractory.
