1. Ukubuka KweMikhiqizo I-silica e-fumed 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 zomhlaba wonke 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 esifana nenethiwekhi (indawo ethile: 50-400 m²/g). Phakathi kwazo, uhlobo lwe-hydrophilic lukhombisa i-hydrophilicity ne-dispersibility ezinhle, kanti uhlobo lwe-hydrophobic lukhombisa 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 ukuwa, ukuqina, kanye nokumelana nokuhlanza. Ngasikhathi sinye, inezinga elihle lokuzinza kwemikhakha futhi iyahambisana nezinhlelo zokukhiqiza ezahlukene ezihlanganisa ezisekelwe kumaseli, ezingenamaseli, nezisekelwe emanzini, ihlangabezana nezidingo eziqinile zokusebenza okuqhubekayo nokwethembeka emikhiqizweni ephakathi naphakathi. 2.
