Leben mullite Corundum

Faa’iidooyinka badeecada: iska caabin heerkulka sare, iska caabinta daxalka, iska caabinta oksaydhka, xasilloonida kuleylka wanaagsan, iyo heerka isbeddelka toosan ee hooseeya.

Codsiga badeecada: Inta badan waxaa loo adeegsadaa warshadaha batroolka, batroolka weyn ee dhexdhexaadka ah iyo kuwa dhexdhexaadka ah ee gaasta ammonia iyo qalabka foornada gaaska maaddada magnetka, qalabka heerkulka sare ee qalabka taageersan agabka, iwm.

sharaxaadda alaabta

Lebenkii Corundum iyo mullite waxay ka samaysan yihiin corundum iyo mullite nadiif ah oo aad u sarreeya sida alaabta ceyriinka ah, oo qaabeeya cadaadis sare oo lagu shido heerkul sare. Badeecadu waxay leedahay astaamaha caabbinta heerkulka sare, iska caabinta daxalka, iska caabinta oksaydhka, xasilloonida kuleylka wanaagsan, iyo heerka isbeddelka toosan ee hooseeya.

Sharaxaadda lebenkii mullite corundum:

1. Agabyada culus waxay leeyihiin isku -dhafnaan wanaagsan, xoog isku -buuqsan oo sarreeya, iska -caabbinta gaasas kala duwan oo daxalaystay, xasilloonida shoogga kaamerada oo wanaagsan, tabinta kuleylka oo aad u fiican, iyo xirashada iska -caabbinta.

2. Alaabta khafiifka ahi waxay leeyihiin qaab -dhismeed gudaha ah oo isku mid ah, xoog isku -buuqsan oo sarreeya, iska -caabbinta daxalka, iska -caabbinta naxdinta kulaylka, iska -caabbinta oksaydhka, heerkulka adeegga sare iyo tabinta kuleylka oo hooseeya.
