POLYCONDENSATI BALANCE AND RHEOLOGICAL ANOMALY IN WATER SILICATE SOLUTIONS

UDK: 691.588 + 546.284

Malyavskii N. I., Pokidko B. V.

The author examine the features of the mechanisms of rheological anomaly involving reversing viscosity increase with increasing temperature in water solutions of four silicates with cations of different types. The crucial role of cation hydrolyzability for the origin of the anomaly was proved. It is shown that the rheological anomaly in lithium silicate solutions is caused by the phase decomposition of the system, not by the polymerization of silicate anions like in aminosilicate solutions.
