Expanded polystyrene, 98 percent is from the air. The air is between the microscopic cell polystyrene foam. This ensures the basic properties of polystyrene. Because the thermal conductivity of air is very small, foam provides excellent thermal insulation. It's no secret that the foam is used everywhere you look. It can be used and the construction site, and warming rooms, floors, walls and loggia. He maintained even for the packing of household appliances and food products. And all because the Styrofoam – non-toxic and harmless to humans and animals.
He does not emits no emissions and harmful substances. Special attention provides equipment for the production of foam. You are pondering how to make grains that make up the styrofoam? Do you know why they stuck together, although the glue residue on them are not obvious? Point is that This material is produced in several iterations. Raw materials from which it is produced, is a small balls. In the first iteration of the production of these grains froth under the influence of steam. Later beads stored for some time in the bunker to left of them, all the liquid. And finally, in the final stage, the individual fractions are joined in a cube in a block form which provides a very high pressure. As a result, turns out big foam block, from which we can produce all that is required.
