1. Ukubuka KweMikhiqizo I-silica efumene iyinano-powder esebenzayo eyenziwa 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 jikelele ze-ISO 1248-2019, kanye nezidingo zokulawulwa kwe-EU REACH. I-Zhonglian Fumed Silica inezici ezisemqoka ezifaka phakathi ukuhlanzeka okuphezulu kakhulu (≥99.8%), usayizi we-particle oyinhloko ongu-nano (7-40nm), kanye nesakhiwo se-network esithathu (indawo ethile: 50-400 m²/g). Phakathi kwazo, uhlobo lwe-hydrophilic lukhombisa ubuhle obukhulu be-hydrophilicity nokuhlanganiswa, kanti uhlobo lwe-hydrophobic lukhombisa ubuhle obukhulu be-hydrophobicity (ukuhlangana kwamanzi ≥120°, ukumuncwa kokungena ≤0.5%). Ezinhlakeni zokunamathela, ukumboza, kanye nezinhlelo zokwakha ezihlanganisiwe, inikeza imisebenzi eyinhloko efana nokwandisa, ukuthuthukiswa kwe-thixotropy, ukuvimbela ukuhamba, ukuvimbela ukuwa, ukuqinisa, kanye nokumelana nokuhlaselwa. Ngasikhathi sinye, inezinga elihle lokuzinza kwezem chemistry futhi iyahambisana nezinhlelo zokukhiqiza ezahlukene kufaka phakathi ezisekelwe kumaseli, ezingenamaseli, nezisekelwe emanzini, ihlangabezana nezidingo eziqinile zokusebenza okuqhubekayo nokwethembeka emikhiqizweni ephakathi nendawo kuya phezulu. 2.
