Mikanda yagalasi imapangidwa ndi inert silicon dioxide (SiO₂), yomwe imaposa 65%. Amakhalanso ndi ma oxides ena, monga sodium oxide (Na₂O) ndi calcium oxide (CaO). Chiŵerengero cha zigawozi zimakhudza thupi ndi mankhwala a galasi mikanda.
Mikanda yagalasi, yomwe imawoneka yophweka koma yosinthasintha, imakhala ndi chuma chambiri cha sayansi ndi zamakono zamakono. Ndiye, kodi mikanda yamagalasi imapangidwa ndi chiyani kwenikweni?
Zida Zazikulu: Silika Inert
Mikanda yagalasi imapangidwa ndi inert silicon dioxide (SiO₂), pawiri ya inorganic yokhala ndi mankhwala apamwamba kwambiri komanso kukhazikika kwamafuta. Silicon dioxide nthawi zambiri imakhala yopitilira 65% ya mikanda yonse yagalasi ndipo ndi gawo lofunikira pamapangidwe ake. Chifukwa cha kusakhazikika kwa silicon dioxide, mikanda yagalasi imawonetsa dzimbiri komanso kukana kuvala, ndikusunga magwiridwe antchito m'malo ovuta.
Zigawo Zina za Oxide: Kuphatikiza pa silicon dioxide, mikanda yagalasi imakhalanso ndi kuchuluka kwa ma oxides ena, monga sodium oxide (Na₂O), calcium oxide (CaO), magnesium oxide (MgO), ndi aluminium oxide (Al₂O₃). Ma oxides awa amagwira ntchito pakuwongolera momwe mikanda yagalasi imagwirira ntchito komanso momwe zimapangidwira. Mwachitsanzo, Kuwonjezera wa sodium okusayidi ndi kashiamu okusayidi akhoza kuchepetsa kusungunuka kutentha kwa galasi ndi kuonjezera Sungunulani fluidity, potero facilitates akamaumba ndi processing wa galasi mikanda. Magnesium oxide ndi aluminium oxide, kumbali ina, amawonjezera kuuma ndi kuvala kukana kwa galasi, potero kumakulitsa moyo wautumiki wa mikanda yagalasi.
