1, if the EPS foam board for external wall insulation system, the apparent density must meet the JG149-2003 "expansion polystyrene board thin plaster external wall insulation system" standard requirements, that is, the apparent density of 18 ~ 22kg / m3.
2, the main body of the building to carry out maintenance, extending the number of construction life. Because the external insulation is placed on the outside of the insulation layer, reducing the temperature changes caused by the deformation caused by the deformation of the stress, and reduce the harmful substances in the air and ultraviolet radiation on the layout.
3, is conducive to maintaining stability at room temperature, the choice of external wall insulation, because the wall can be a larger layout of the wall in the layout of the wall, is conducive to maintaining stability at room temperature.
4, polystyrene materials with its light, shock, drop, heat insulation, sound insulation, self-extinguishing, environmental protection, anti-aging, low cost, easy construction and other advantages are widely used in construction and packaging industry.
5, foaming EPS beads are heated to above 90 ℃, the beads softening, foaming agent can make EPS beads expansion 40-80 times.
