Abstract
Information is provided about the stability of polysilicates solutions, obtained by mixing liquid glass and silica sol. It was found, that at increases the amount of silicic acid sol added, the pH of the solutions decreases with an unchanged alkali concentration. Information on the structure of polysilicate solutions are given. It has been found, that addition of the sol (increasing the silicate module) contribute to prolonging fraction of high-polymer fractions of silicic anion. The dependence of the silica content of the monomeric form of α-SiO2in the early stages of interaction between the sol and liquid glass is extreme. The maximum content of α-SiO2 depends on the type of liquid glass and the amount of sol. It is shown, that films based on polysilicates solutions, are characterized by faster curing. The manifestation of the scale factor for coatings based on polysilicate solutions was revealed.
