Hydrophobic Fumed Silica
Product Sumo
Fumed silica, kanapyrogenic silica, colloidal silicon dioxide, is amorphous white inorganic powder iyo ine yakakwirira chaiyo nzvimbo, nano-scale primary particle saizi uye yakakwira (pakati pezvigadzirwa zvesilica) kuunganidzwa kwemapoka epasi silanol. Zvimiro zvefumed silica zvinogona kugadziridzwa kemikari nekuita nemapoka aya silanol.
Commercial inowanikwa fumed silica inogona kukamurwa kuita mapoka maviri: hydrophilic fumed silica uye hydrophobic fumed silica. inoshandiswa zvakanyanya sechinhu chakakosha mumaindasitiri mazhinji akadai sesilicone rubber, pendi uye mapurasitiki maindasitiri.
