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 zokulawulwa kwe-EU REACH. I-Zhonglian Fumed Silica inezici eziyisisekelo ezihlanganisa ubuqotho obuphezulu kakhulu (≥99.8%), usayizi wephezulu we-nano-scale (7-40nm), kanye nesakhiwo esihlanganisiwe esifana nenethiwekhi (indawo ethile yokuphuma: 50-400 m²/g). Phakathi kwazo, uhlobo lwe-hydrophilic lubonisa i-hydrophilicity enhle kanye nokuhlangana, kanti uhlobo lwe-hydrophobic lubonisa i-hydrophobicity ephawulekayo (ukuhlangana kwamanzi ≥120°, ukumunca umswakama ≤0.5%). Ku-sistimu ye-adhesive, coating, kanye nezinto ezihlanganisiwe, inikeza imisebenzi eyisisekelo efana nokwandisa, ukuthuthukiswa kwe-thixotropy, ukuvimbela ukuhamba, ukuvimbela ukuhamba phansi, ukuqinisa, kanye nokumelana nokuhlanza. Ngasikhathi sinye, inezinga elihle lokuzinza kwezemithi futhi iyahambisana nezinhlelo zokukhiqiza ezahlukene ezihlanganisa ezisekelwe kumaseli, ezingenamaseli, kanye nezisekelwe emanzini, ihlangabezana nezidingo eziqinile zokusebenza okuqhubekayo nokwethembeka emikhiqizweni ephakathi naphakathi. 2.
