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 zomhlaba wonke ze-ISO 1248-2019, kanye nezidingo zok regulation ze-EU REACH. I-Zhonglian Fumed Silica inezici eziyisisekelo ezihlanganisa ukuhluza okuphezulu (≥99.8%), usayizi we-particle oyinhloko we-nano-scale (7-40nm), kanye nesakhiwo esihlanganisiwe esinjengezinkanyezi (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%). Ku-adhesive, coating, kanye nezinhlelo zokwakha ezihlanganisiwe, inikeza imisebenzi eyisisekelo efana nokwandisa, ukuthuthukiswa kwe-thixotropy, ukuvimbela ukuhamba, ukuvimbela ukuhamba, ukuqina, kanye nokumelana nokuhlaselwa. Ngasikhathi sinye, inezinga elihle lokuzinza kwekhemikhali futhi iyahambisana nezinhlelo zokukhiqiza ezahlukene ezihlanganisa ezisekelwe kumaseli, ezingenamaseli, nezisekelwe emanzini, ihlangabezana nezidingo eziqinile zokuhambisana kokusebenza kanye nokwethembeka emikhiqizweni ephakathi nendawo kuya phezulu. 2.
