【摘要】 研究了不同条件下纳米二氧化硅粒径对酸性硅溶胶稳定性、粘度的影响。结果表明,随着二氧化硅粒径的增加,酸性硅溶胶的稳定性及粘度均得到较好的改善,提高纳米二氧化硅的粒径对制备高浓度、低粘度的酸性硅溶胶有十分重要的作用。更多还原

【Abstract】 From the study of the relationship between the stability andviscosity of acidic silica sol andthe grain diameter of nanon silicon dioxide particle in.different conditions,we found that the stability andviscosity of said sol would improve with the increasing of the diameter of said particle.And it is crucial toincrease the diameter of said particle for the preparation of high concentration and low viscosity acidic silica sol.更多还原
