摘要
以水玻璃为原料,采用静电雾化法制备二氧化硅,研究静电雾化法制备二氧化硅的相关试验条件对二氧化硅粒径大小的影响.试验结果表明,随着外加电压增加或者电极间距减小,施加在放电电极的静电力增强,水玻璃流速变快,由水滴逐渐变成线直至成雾状;形成的二氧化硅微粒粒径逐渐变小;随着脉冲频率升高,二氧化硅微粒粒径也逐渐变小.
In the present study,pulsed high voltage is applied to produce silica particles with water glass.It is easy to control and get controlled diameter in wide range.The paper studies the conditions which affects the diameter of the silica particle.The atomized water glass droplets are solidified by removing water molecules from the water glass.When the pulse voltage and the frequency are raised,the mean diameter of the silica particles is reduced.
