Asidi silika ramming zinthu kwa ng’anjo yapakati pafupipafupi

Asidi silica ramming zinthu zapakati pafupipafupi ng’anjo amapangidwa ndi mkulu-kuyera quartz ndi silika wosakanizidwa monga zopangira zazikulu, ndi zina zosakaniza ntchito ngati sintering agents.

Kumanga kwa ng’anjo yokhala ndi acidic silica ramming ng’anjo yapakati pafupipafupi: Gwiritsani ntchito izi ndikuwonjezera madzi apampopi pafupifupi 4% kuti musakanize ndikuyamba kumanga.

Pambuyo pomanga ramming, chotsani chikombole chachikulu, pang’onopang’ono kuphika uvuni, wouma bwino, ndikuwotcha pang’onopang’ono pamene ng’anjo imayatsidwa musanayigwiritse ntchito.
