Silica silica oo loogu talagalay waddooyinka II ee fasalka II ee la taaban karo

Silica silica ee fasalka II ee la taaban karo ( Silica silica oo la taaban karo oo xoog badan: 90% 92% 95%) Waa lagu dari karaa sidii wax lagu karsado la taaban karo ee ganacsiga ee meelo kala duwan. Saamaynta microsilica ee caabbinta qabowga ee la taaban karo. Marka laga hadlayo saameynta silica u caabbinta dhaxan ee la taaban karo, daraasado badan oo ka mid ah guriga iyo dibedda ayaa muujiyay in kiiska wax ka beddelka ka yar 15% ka mid ah silica Fme la taaban karo. Asal ahaan isku mid ah, iyo mararka qaar waa la wanaajin doonaa (sida qaddarka isku-darka 5% illaa 10%), laakiin xaddiga isku-darka ah ee in ka badan 20% ayaa si cad u yareyn doona caabbinta dhaxan ee silica femete la taaban karo. Silica Fme iyo Isku-darka Alkali-Cence-ka ee celceliska gudaha iyo heerka caalamiga ayaa muujinaya in caqabadaha silica ay faa'iido u leedahay in la xakameeyo falcelin isku-darka alkali ee la taaban karo. Markaad xisaabineyso wadarta guud ee alkali ee la taaban karo, alkali wax ku oolka ah ee uu keeno silica ee loo yaqaan 'Freme' waxaa loo xisaabiyaa 50% wadarta guud ee alkali.
