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 zok regulation ze-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 ubuhle obukhulu be-hydrophilicity kanye nokuhlangana, kanti uhlobo lwe-hydrophobic lukhombisa ubuhle obukhulu be-hydrophobicity (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 nokugwazwa. Ngasikhathi sinye, inezinga elihle lokuzinza kwemichiza futhi iyahambisana nezinhlelo zokukhiqiza ezahlukene kuhlanganisa ezisekelwe kumaseli, ezingenamaseli, nezisekelwe emanzini, ihlangabezana nezidingo eziqinile zokusebenza okuqhubekayo nokwethembeka emikhiqizweni ephakathi nendawo kuya phezulu. 2.
