Polystyrene foam board – also known as foam board, EPS board is mold white object that expandable polystyrene beads contained a volatile liquid foaming agent upon heating advance, heating and molding. According to the structural features of its fine closed cells, EPS is mainly used for building walls, roof insulation, composite board insulation, cold storage, air conditioning, vehicle, ship insulation, floor heating, decorating carving.
Polystyrene foam board – use effect
1. The main structure of the building to protect and extend the life of the building. Since the outer insulation is placed outside the insulation layer structure, reducing the pressure due to structural deformation caused by temperature changes, and to reduce harmful substances in the air and ultraviolet structural erosion.
2. Effectively eliminate the “thermal bridge” previously used in the insulation, “thermal bridge” is difficult to avoid, and wall insulation to effectively prevent the generation of thermal bridges, to avoid condensation.
3. Make the moist walls improve the situation, the general need to set up within the polystyrene insulation vapor barrier, thermal insulation and through the use of external temperature performance of insulation materials is far stronger than the main structure, generally does not occur in the wall inside condensation, structural layer the entire wall temperature has increased to further enhance the thermal insulation properties of the wall.
4. conducive to room temperature remained stable, the use of exterior insulation, wall heat storage capacity due to the greater structural layer on the inside of the wall, in favor remain stable at room temperature.
5. Increase the housing area. To avoid damage to the second decoration insulation.
Most of polystyrene packaging material are disposable, used it becomes waste. Here are just waste polystyrene recycling.
Styrofoam molding method, there are two: one is the direct foaming process, the other is can be made of beads. The two methods are physical processes, does not destroy polystyrene polymer structure, it remains original character. Therefore is recyclable. for example, the food trays recycling process is:
Waste food trays → washing → drying → crush → Forced feeding → plastics extrusion (head with quick change filter) → forming → cooling → granulation → bagging
