1. Ukubuka KweMikhiqizo 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 izakhiwo zayo ezithambile ngokusekelwe ezidingweni zokusebenza. Umkhiqizo uhambisana ngokuqinile 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 we-nano-scale (7-40nm), kanye nesakhiwo esihlanganisiwe esifana nenethiwekhi (indawo ethile yokuphila: 50-400 m²/g). Phakathi kwazo, uhlobo lwe-hydrophilic lukhombisa ubuhle obukhulu bokuhlanza nokuhlanganiswa, kanti uhlobo lwe-hydrophobic lukhombisa ubuhle obuphezulu bokungena emanzini (ukuthinta kwamanzi ≥120°, ukutholwa kokungena ≤0.5%). Ku-sistimu ye-adhesive, yokufaka, kanye nezinto ezihlanganisiwe, inikeza imisebenzi eyisisekelo efana nokwandisa, ukuthuthukiswa kwe-thixotropy, ukuvimbela ukuhamba, ukuvimbela ukuwa, ukuqina, nokumelana nokuhlanza. Ngasikhathi sinye, inezinga elihle lokuzinza kwemichiza futhi iyahambisana nezinhlelo ezahlukene zokukhiqiza ezihlanganisa ezisekelwe kumaseli, ezingenamaseli, nezisekelwe emanzini, ihlangabezana nezidingo eziqinile zokusebenza okuqhubekayo nokwethembeka emikhiqizweni ephakathi nendawo kuya phezulu. 2.
