Moreover, in the early stages the most promising application of a 40% solution as an additive in polystyrene mixture in an amount up to 2% by weight of polystyrene, thus achieving a reduction in consumption of liquid glass in 2 times, increase the strength of the mixture in dried state at 8-10. But in this case we find that the positive effect that These mixtures are legkovybivaemymi, upon heating above 300 C, they can easily spill out of the cavities of the casting, sand cores made. Thus, by adjusting in the range of 1-2% of this additive, engineer-founder gets gamut legkovybivaemyh mixtures for various conditions of casting (mass casting a rod, a kind of alloy), the competitive strength of resin. A design for recycling polystyrene foam technology by dissolving the gum in turpentine obtained data show a very wonderful opportunity to compaction. According to the table in one unit (46 cm3) of 40% solution is placed 19.14 volume units (880.5 cm3) of waste polystyrene foam, and with respect to source 30 cm3 of solvent that the volume of waste more time in 29.35.
