Silikoni Dioxide CAS 7631-86-9
Silicon dioxide ndi mankhwala abwino olimbikitsira rabara, omwe amatha kukulitsa mphamvu yokoka ndi kukana kukalamba kwa rabara yovunda, kuchepetsa kuchuluka kwa rabara yomwe imagwiritsidwa ntchito, kuchepetsa ndalama, komanso kukhala ndi mphamvu yolimba, zomwe zimapangitsa kuti ikhale ndi mphamvu yofalikira kwambiri mu rabara yaiwisi. Kapangidwe ka thupi ka tinthu ta silika ndi tinthu ta rabara ndi kabwino kuposa ka carbon black pakuwonjezera mphamvu ya makina ndi mphamvu yong'ambika ya rabara yovunda.

Silicon dioxide imagwiritsidwa ntchito m'mafakitale monga matayala, zinthu za rabara zowonekera pang'ono komanso zowonekera kwambiri, komanso zingwe za rabara ndi zingwe. Imagwiritsidwa ntchito makamaka m'zinthu za rabara monga malamba oyendera ndi ma roller a rabara.
Silika (SiO2) (RI: 1.48) imakumbidwa kuchokera ku miyala yofewa ngati choko (keiselghur). Ili ndi gulu lofunika kwambiri la utoto wowonjezera, womwe umagwiritsidwa ntchito m'mitundu yosiyanasiyana ya tinthu tating'onoting'ono. Amagwiritsidwa ntchito ngati chochepetsera kuwala kwa zokutira zowonekera bwino komanso kupereka mawonekedwe ochepetsera kuyenda kwa zokutirazo. Ndi okwera mtengo kwambiri.
