1. Ukubuka KweMikhiqizo I-fumed silica iyinano-powder esebenzayo eyenziwa ngenqubo ye-fumed (ukuhlanza okuphezulu kwe-silicon tetrachloride emlilweni we-oxy-hydrogen). Ingashintshwa ebusweni (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 zok regulation ze-EU REACH. I-Zhonglian Fumed Silica inezici eziyisisekelo ezihlanganisa ukuhluza okuphezulu (≥99.8%), usayizi we-particle oyinhloko ongu-nano (7-40nm), kanye nesakhiwo esihlanganisiwe esinokwakheka kwezithombe ezintathu (indawo ethile: 50-400 m²/g). Phakathi kwazo, uhlobo lwe-hydrophilic lukhombisa i-hydrophilicity enhle kanye nokuhlanganiswa, kanti uhlobo lwe-hydrophobic lukhombisa i-hydrophobicity ephawulekayo (i-water contact angle ≥120°, ukuhlanganiswa kokunwetshwa ≤0.5%). Ku-adhesive, coating, kanye nezinhlelo zokwakha ezihlanganisiwe, inikeza imisebenzi eyisisekelo efana nokwandisa, ukuthuthukiswa kwe-thixotropy, ukuvimbela ukuhamba, ukuvimbela ukuwa, ukuqinisa, kanye nokumelana nokuhlanza. Ngasikhathi sinye, inezinga elihle lokuzinza kwemichiza futhi iyahambisana nezinhlelo ezahlukene zokukhiqiza ezihlanganisa ezisekelwe kumaseli, ezingenamaseli, nezisekelwe emanzini, ihlangabezana nezidingo eziqinile zokuhambisana kokusebenza nokwethembeka emikhiqizweni ephakathi nendawo kuya phezulu. 2.
