1. Ukubuka KweMikhiqizo I-Fumed silica iyinano-powder esebenzayo eyenziwa 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 ezifaka phakathi ukujula okuphezulu (≥99.8%), usayizi wepulasitiki oyinhloko we-nano (7-40nm), kanye nesakhiwo esihlanganisiwe esifana nenethiwekhi (indawo ethile yokuphuma: 50-400 m²/g). Phakathi kwazo, uhlobo lwe-hydrophilic lukhombisa i-hydrophilicity enhle kanye nokuhlangana, kanti uhlobo lwe-hydrophobic lukhombisa i-hydrophobicity ephawulekayo (ukuthinta kwamanzi ≥120°, ukuwabamba ≤0.5%). Ku-sistimu ye-adhesive, yokufafaza, kanye nezinto ezihlanganisiwe, inikeza imisebenzi eyisisekelo efana nokwandisa, ukuthuthukiswa kwe-thixotropy, ukuvimbela ukuhamba, ukuvimbela ukuhamba, ukuqinisa, kanye nokumelana nokuhlanza. Ngasikhathi sinye, inezinga elihle lokuzinza kwemikhakha futhi iyahambisana nezinhlelo zokukhiqiza ezahlukene kufaka phakathi ezisekelwe kumaseli, ezingenamaseli, kanye nezisekelwe emanzini, ihlangabezana nezidingo eziqinile zokuhambisana kokusebenza nokwethembeka emikhiqizweni ephakathi nendawo kuya phezulu. 2.
