1. Ukuhlaziywa Komkhiqizo 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 zamazwe omhlaba 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 esinokwakheka kwezithombe ezintathu (indawo ethile: 50-400 m²/g). Phakathi kwazo, uhlobo lwe-hydrophilic lubonisa i-hydrophilicity enhle kanye nokuhlangana, kanti uhlobo lwe-hydrophobic lukhombisa i-hydrophobicity ephawulekayo (i-angle yokuxhumana namanzi ≥120°, ukumunca umswakama ≤0.5%). Ezinhlakeni zokunamathela, zokufaka, nezinto ezihlanganisiwe, inikeza imisebenzi eyisisekelo efana nokwandisa, ukuthuthukiswa kwe-thixotropy, ukuvimbela ukuhamba, ukuvimbela ukuhamba phansi, ukuqina, nokumelana nokuhlaselwa. Ngasikhathi sinye, inezinga elihle lokuzinza kwezemithi futhi iyahambisana nezinhlelo zokukhiqiza ezahlukene ezihlanganisa ezisekelwe kumaseli, ezingenamaseli, nezisekelwe emanzini, ihlangabezana nezidingo eziqinile zokusebenza okuqhubekayo nokwethembeka emikhiqizweni ephakathi naphakathi. 2.
