1. Isithombe Somkhiqizo I-silica efumene iyinano-powder esebenzayo eyenziwe ngenqubo efumene (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 nezindinganiso zezimboni, izincazelo zamazwe omhlaba ze-ISO 1248-2019, kanye nezidingo zokulawulwa kwe-EU REACH. I-Zhonglian Fumed Silica inezici eziyisisekelo ezihlanganisa ukujula okuphezulu (≥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 enhle kanye nokuhlangana, 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 ukuwa, ukuqinisa, kanye nokumelana nokuhlanza. Ngasikhathi sinye, inezinga elihle lokuzinza kwezemithi futhi iyahambisana nezinhlelo zokukhiqiza ezahlukene kufaka phakathi ezisekelwe kumaseli, ezingenamaseli, kanye nezisekelwe emanzini, ihlangabezana nezidingo eziqinile zokuhambisana kokusebenza nokwethembeka emikhiqizweni ephakathi naphakathi. 2.
