1. Ukubuka KweMikhiqizo I-silica efumene iyinano-powder esebenzayo eyenziwe ngenqubo efumene (ukuhlanza okushisayo kwe-silicon tetrachloride emlilweni we-oxy-hydrogen). Ingashintshwa ukuze ibe ne-surface (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 ukuhlanzeka okuphezulu kakhulu (≥99.8%), usayizi we-particle oyinhloko we-nano-scale (7-40nm), kanye nesakhiwo se-network esithathu (indawo ethile: 50-400 m²/g). Phakathi kwazo, uhlobo lwe-hydrophilic lukhombisa i-hydrophilicity enhle kanye ne-dispersibility, kanti uhlobo lwe-hydrophobic lukhombisa i-hydrophobicity ephawulekayo (ukuhlangana kwamanzi ≥120°, ukumunca umswakama ≤0.5%). Ezinhlanganweni zokunamathisela, zokufaka, nezinto ezihlanganisiwe, inikeza imisebenzi eyisisekelo efana nokwandisa, ukuthuthukiswa kwe-thixotropy, ukuvimbela ukuhamba, ukuvimbela ukuwa, ukuqinisa, nokumelana nokuhlanza. Ngasikhathi sinye, inezinga elihle lokuzinza kwezem chemistry futhi iyahambisana nezinhlelo zokukhiqiza ezahlukene kuhlanganisa ezisekelwe kumaseli, ezingenamaseli, nezisekelwe emanzini, ihlangabezana nezidingo eziqinile zokusebenza okuqhubekayo nokwethembeka emikhiqizweni ephakathi naphakathi. 2.
