Every time after entering into the solution calculated by addition of waste polystyrene dimensional cylinder fixed volume of solution of a given concentration. It should be noted that all were weighing on electronic scales model E134 plant 'Gosmetr' (St. Petersburg) in increments of 5 mg of reference. Table presented a number of characteristics of the processes of obtaining solutions of polystyrene in the waste of gum turpentine, depending on their concentration. Graphically, the majority of the data shown. If the concentration solutions we have previously wondered (10-20-30-40%), the most important results – volumes of solutions of a given composition and concentration – have been obtained from these experiments.
In the future, using the original data, calculated obtained by other characteristics of the processes the preparation of solutions of a given concentration. It is important to emphasize that all these data were obtained by the most rational way, ie in one experiment (in a measuring cylinder). The sequence of operations and measurements carried out with each of the solutions with increasing concentrations of 10-20-30-40%. Thus, the table shows, both with increasing concentration of the solution increases its mass, respectively (P, r) and volume (V, cm3). The corresponding data are listed in the table not only in metric units, but also as a percentage. If we take the initial volume of turpentine over 100%, with an increase in the concentration of solutions, this volume increases, and 40% concentration, it increases more than 1.5 times. The findings have practical importance for the establishment of industrial processes for solutions of polystyrene in the waste of gum turpentine. They give information, what should be the initial volume of gum turpentine, depending on the volume of container to mix the desired concentration, such as a capacity appropriate to set a car on simultaneous collection and dissolution of polystyrene waste that goes round the accumulation points of such wastes.
