1. Ukubuka KweMikhiqizo I-silica efumene iyinano-powder esebenzayo eyenziwe ngenqubo efumene (ukuhlanza okushisayo kwe-silicon tetrachloride emlilweni we-oxy-hydrogen). Ingashintshwa ubuso (uhlobo lwe-hydrophobic) noma igcine izici zayo ezisemqoka ze-hydrophilic ngokuya ngezidingo zokusebenza. Umkhiqizo uhambisana ngokuqinile nezindinganiso zezimboni, izincazelo zomhlaba wonke ze-ISO 1248-2019, kanye nezidingo zokulawulwa kwe-EU REACH. I-Zhonglian Fumed Silica inezici eziyisisekelo ezihlanganisa ubuqotho obuphezulu (≥99.8%), usayizi we-particle oyinhloko ongu-nano (7-40nm), kanye nesakhiwo esihlanganisiwe esifana nenethiwekhi (indawo ethile: 50-400 m²/g). Phakathi kwazo, uhlobo lwe-hydrophilic lukhombisa i-hydrophilicity enhle kanye nokuhlangana, kanti uhlobo lwe-hydrophobic lukhombisa i-hydrophobicity ephawulekayo (ukuhlangana kwamanzi ≥120°, ukumuncwa kokungcola ≤0.5%). Ezinhlakeni zokunamathela, ukumboza, nezinto ezihlanganisiwe, inikeza imisebenzi eyisisekelo efana nokwandisa, ukuthuthukiswa kwe-thixotropy, ukuvimbela ukuhamba, ukuvimbela ukuwa, ukuqina, nokumelana nokuhlanza. Ngasikhathi sinye, inezinga elihle lokuzinza kwekhemikhali futhi iyahambisana nezinhlelo ezahlukene zokukhiqiza ezihlanganisa ezisekelwe kumaseli, ezingenamaseli, nezisekelwe emanzini, ihlangabezana nezidingo eziqinile zokusebenza okuqhubekayo nokwethembeka emikhiqizweni ephakathi nendawo kuya phezulu. 2.
