摘要
作者通过实验证明水玻璃的物理改性机理,是往体系中供给能量,促使水玻璃中聚硅酸分子量重新均匀化,消除了老化现象;化学改性的机理是靠化学吸附降低聚硅酸分子间缩聚倾向,阻缓了水玻璃的老化。
The physical modification mechanism of the modified water-glass has been proved by experiments which is to supply energy for the silicate System to rehomogenize the molecular weight of the polysilicic acids and then eliminate the aging phenomena of the water-glass. The chemical modification mechanism is to reduce the polycondensa-tion tendency of polysilicic acids in water-glass due to the chemical adsoption and obstruct the aging phenomena of it.
