Silicon Dioxide CAS 7631-86-9
Silicon dioxide ndi yabwino kulimbitsa mphira, yomwe imatha kupititsa patsogolo kulimba kwamphamvu komanso kuvala kukana kwa mphira wowombedwa, kuchepetsa kuchuluka kwa mphira wogwiritsidwa ntchito, kuchepetsa mtengo, komanso kukhala ndi mgwirizano wamphamvu, kupangitsa kuti ikhale ndi kuthekera kwakukulu kobalalika mu rabara yaiwisi. The thupi katundu wopangidwa ndi particles wa silika ndi mphira particles bwino kuposa mpweya wakuda mu utithandize mawotchi mphamvu ndi misozi mphamvu ya mphira vulcanized.

Silicon dioxide imagwiritsidwa ntchito m'mafakitale monga matayala, zinthu zowoneka bwino komanso zowonekera kwambiri, komanso zitsulo ndi zingwe. Amagwiritsidwa ntchito kwambiri pazinthu zamphira monga malamba oyendetsa ndi zodzigudubuza.
Silika (SiO2) (RI: 1.48) amakumbidwa kuchokera ku miyala ya diatomaceous choko yofewa (keiselghur). Ili ndi gulu lofunikira la ma extender pigments, omwe amagwiritsidwa ntchito mumitundu yosiyanasiyana ya tinthu tating'onoting'ono. Amagwiritsidwa ntchito ngati chowongolera kuti achepetse kung'anima kwa zokutira zomveka bwino komanso kuti azitha kumeta ubweya wa ubweya ku zokutira. Iwo ndi okwera mtengo.
