1. Ukubuka KweMikhiqizo I-Fumed silica iyinano-powder esebenzayo eyenziwe ngenqubo ye-fumed (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 zok regulation ze-EU REACH. I-Zhonglian Fumed Silica inezici eziyisisekelo ezihlanganisa ukuhluza okuphezulu (≥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 lukhombisa i-hydrophilicity enhle kanye nokuhlanganiswa, kanti uhlobo lwe-hydrophobic lukhombisa i-hydrophobicity ephawulekayo (ukuthinta kwamanzi ≥120°, ukumuncwa kokungcola ≤0.5%). Ezinhlakeni zokunamathela, zokufaka, nezinto ezihlanganisiwe, inikeza imisebenzi eyisisekelo efana nokwandisa, ukuthuthukiswa kwe-thixotropy, ukuvimbela ukuhamba, ukuvimbela ukuwa, ukuqinisa, nokumelana nokuhlaselwa. Ngasikhathi sinye, inezinga elihle lokuzinza kwezemithi futhi iyahambisana nezinhlelo zokukhiqiza ezahlukene ezihlanganisa ezisekelwe kumaseli, ezingenamaseli, nezisekelwe emanzini, ihlangabezana nezidingo eziqinile zokusebenza okuhambisanayo nokwethembeka emikhiqizweni ephakathi nendawo kuya phezulu. 2.
