用胶凝法研究酸化了的不同摩尔比 (Si O2 /Na2 O)的硅酸钠溶液的胶凝速度 ,发现在恒盐条件下 ,硅酸胶凝速度常数是 2 ,这个结果和我们过去所提出的硅酸聚合机制符合一致。
The gelation rate of acidified sodium silicate solution with different mole ratios (Si O2 / Na2 O) was studied by gelation method. It was found that under the constant salt condition, the gelation speed constant of silicic acid is 2, which is the same as that of our past The proposed silicic acid polymerization mechanism is consistent.
