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 ubuqotho obuphezulu (≥99.8%), usayizi we-particle omncane (7-40nm), kanye nesakhiwo esihlanganisiwe esifana nenethiwekhi (indawo ethile: 50-400 m²/g). Phakathi kwazo, uhlobo lwe-hydrophilic lukhombisa ubuhle obukhulu be-hydrophilicity kanye nokuhlangana, kanti uhlobo lwe-hydrophobic lukhombisa ubuhle obukhulu be-hydrophobicity (ukuhlangana kwamanzi ≥120°, uku吸湿 ≤0.5%). Ku-adhesive, coating, kanye nezinhlelo zokwakha, inikeza imisebenzi eyisisekelo efana nokwandisa, ukuthuthukiswa kwe-thixotropy, ukuvimbela ukuhamba, ukuvimbela ukuwa, ukuqina, kanye nokumelana nokuhlanza. Ngasikhathi sinye, inezinga elihle lokuzinza kwe-chemical futhi iyahambisana nezinhlelo zokukhiqiza ezahlukene kufaka phakathi ezisekelwe kumaseli, ezingenamaseli, nezisekelwe emanzini, ihlangabezana nezidingo eziqinile zokusebenza kokuhambisana nokwethembeka emikhiqizweni ephakathi nendawo kuya phezulu. 2.
