1, polyurethane foam color steel sandwich panel PU
Polyurethane foam color steel sandwich panel is made of flame retardant rigid polyurethane foam as the core material and color coated steel plate as the surface material. At present, rigid polyurethane sandwich panels with metal surface are widely used in industrial workshops, warehouses, stadiums, civil houses, villas, prefabricated houses, combined cold storage and other buildings in China, but the disadvantages are high equipment requirements, large initial investment and great difficulty in industrialization.
2, polystyrene foam color steel sandwich panel EPS
Polystyrene is the white foam that we often see. This kind of color steel plate is cheap, waterproof and not deformed. The prefabricated houses on the construction site are mostly polystyrene sandwich panels, which are widely used, but the polystyrene foam sandwich panel is not fireproof and has the worst insulation effect.
3, phenolic foam color steel sandwich panel PF
Phenolic foam color steel sandwich panel is a composite panel with color steel plate as surface material and phenolic foam as core material. Phenolic foam is fragile, fragile and corrosive, and the residual acid in the foam has corrosive effect on metal materials.
4. Rock wool color steel sandwich panel
Rock wool color steel sandwich panel has good fire resistance, but rock wool color steel plate is not waterproof and produces toxic substances when it meets fire, which causes great pollution.
5. Paper honeycomb color steel sandwich panel
Paper honeycomb sandwich panel can completely recycle waste, and it is a substitute product of polystyrene board, polyurethane, rock wool and other materials. Widely used in electronics, hospital operating rooms, laboratories and other clean engineering fields, but the waterproof effect is poor and the price is relatively expensive.
6. Aluminum honeycomb sandwich panel
Aluminum honeycomb color steel sandwich panel is made of aluminum honeycomb core panel, compounded with special high-strength adhesive and color steel plate, supported by special aluminum alloy keel, and cured by heating and pressure. Compared with other sandwich panels, it has light weight and good flatness, and belongs to green building materials, but the cost is the highest.
