1. Ukuhlaziywa Komkhiqizo I-silica efumene iyinano-powder esebenzayo eyenziwe ngenqubo efumene (ukuhlanza okushisayo kwe-silicon tetrachloride emlilweni we-oxy-hydrogen). Ingashintshwa ubuso (uhlobo olungathathi hlangothi) noma igcine izici zayo ezisemqoka zokuthatha amanzi ngokuya ngezidingo 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 ongu-nano (7-40nm), kanye nesakhiwo esihlanganisiwe esifana nenethiwekhi (indawo ethile yokusebenza: 50-400 m²/g). Phakathi kwazo, uhlobo oluthatha amanzi lukhombisa ukujula okuhle kokuthatha amanzi nokuhlanganiswa, kanti uhlobo olungathathi hlangothi lukhombisa ukujula okuhle kokungathathi hlangothi (ukuhlangana kwamanzi ≥120°, ukutholwa kokungena ≤0.5%). Ezinhlakeni zokunamathela, zokufaka, nezinto ezihlanganisiwe, inikeza imisebenzi eyisisekelo efana nokwandisa, ukuthuthukiswa kwe-thixotropy, ukuvimbela ukuhamba, ukuvimbela ukuhamba, ukuqina, nokumelana nokuhlanza. Ngasikhathi sinye, inezinga elihle lokuzinza kwezemvelo futhi iyahambisana nezinhlelo zokukhiqiza ezahlukene kufaka phakathi ezisekelwe kumaseli, ezingenamaseli, nezisekelwe emanzini, ihlangabezana nezidingo eziqinile zokuhambisana kokusebenza nokwethembeka emikhiqizweni ephakathi naphakathi. 2.
