Ukubonisa umlingani
1. Ukubuka Konke Komkhiqizo
I-fumed silica iyi-nano-powder esebenzayo ekhiqizwa ngenqubo ye-fumed (i-hydrolysis yokushisa okuphezulu ye-silicon tetrachloride elangeni le-oxy-hydrogen). Ingashintshwa ebusweni (uhlobo olungenawo amanzi) noma igcine izakhiwo zayo zemvelo zokuthanda amanzi kuye ngezidingo zokusetshenziswa. Umkhiqizo uhambisana ngokuqinile namazinga emboni, izicaciso zamazwe ngamazwe ze-ISO 1248-2019, kanye nezidingo zokulawula ze-EU REACH. I-Zhonglian Fumed Silica inezici eziyisisekelo ezihlanganisa ukuhlanzeka okuphezulu kakhulu (≥99.8%), usayizi wezinhlayiya zokuqala ze-nano (7-40nm), kanye nesakhiwo esihlangene esifana nenethiwekhi yezinhlangothi ezintathu (indawo yomhlaba ethile: 50-400 m²/g). Phakathi kwazo, uhlobo oluthanda amanzi lubonisa ukuthanda amanzi nokusabalalisa okuhle kakhulu, kuyilapho uhlobo olungenawo amanzi lubonisa ukungena kwamanzi okuphawulekayo (i-engeli yokuxhumana namanzi ≥120°, ukumuncwa komswakama ≤0.5%). Ezinhlelweni ze-glue, i-coating, nezinto ezihlanganisiwe, inikeza imisebenzi eyisisekelo njengokuqinisa, ukuthuthukisa i-thixotropy, ukuvimbela ukuhla, ukuvimbela ukugxeka, ukuqinisa, nokumelana nokuklwebheka. Ngasikhathi sinye, inezici zokuzinza kwamakhemikhali okuhle kakhulu futhi ihambisana nezinhlelo ezahlukene zokukhiqiza ezihlanganisa izinhlelo ezisekelwe ku-solvent, ezingenayo i-solvent, nezisekelwe emanzini, okuhlangabezana nezidingo eziqinile zokungaguquguquki kokusebenza nokuthembeka emikhiqizweni yezinga eliphakathi nendawo.
