    摘要: The invention provides a method for improving the effectiveness of colloidal silica. The method involves removing enough charged impurities from the colloid to prevent the charged particles from causing the colloid to become a viscous gel. The method however also involves not removing too many charged particles so the silica material doesn't gel by cross-linking with itself. This method is quite effective because it recognizes that materials that have accumulated during the formation of the colloid do perform an important function, but they can perform better at a lower concentration.

    摘要翻译: 本发明提供了一种改善胶态二氧化硅的有效性的方法。 该方法包括从胶体中除去足够的带电杂质以防止带电粒子引起胶体变成粘性凝胶。 然而,该方法也不包括除去太多的带电粒子,因此二氧化硅材料不会通过与其自身交联而凝胶化。 这种方法是非常有效的,因为它认识到在胶体形成期间积累的材料确实具有重要的功能,但是它们可以在较低浓度下表现更好。
