OVER-STABILIZED BITUMEN EMULSIONS MADE FROM EMULSIFIERS FOR SLOW-SETTING EMULSIONS

Formulations of road over-stabilized cationic bitumen emulsions with orthophosphoric, sulfuric and hydrochloric acids and cationic emulsifiers for slowly disintegrating emulsions have been designed. The physical and mechanical properties of the manufactured over-stabilized bitumen emulsions and their breaking behavior were determined. It has been established that over-stabilised bitumen emulsions demonstrate good storage stability for 180 days.

Rate of components evaporation from sulfuric acid solution during its concentrating in air flow

A method of experimental determination of components evaporation rate from a sulfuric acid solution during its concentrating in the flow of neutral gas is proposed. Using this methodology, the dependence of the evaporation rate on the composition of the acid solution is set. The critical value of the weight fraction of water in the solution was found at which the character of this dependence changed. An empirical equation for the approximate calculation of the evaporation rate of components from solution in the air flow was obtained.
