Precautions when storing sandwich panels

The cores used in sandwich panels mainly include phenolic foam, polyphenylene, extruded polystyrene, rigid polyurethane, tripolyester and rock wool, etc., and phenolic foam has excellent fireproof and thermal insulation properties, which cannot be replaced by other materials. For example, the thermal insulation effect of phenolic foam is more than twice that of polystyrene, and its fire resistance is also higher than that of polyurethane. When polyurethane is burned, it will release thick smoke containing hydrogen cyanide.

The sandwich panel can be fireproof from six aspects: First, rock wool with good fireproof performance is used as the core material, which is a solution to the root cause. Second, during the construction process, the core material should be kept away from open flame operations such as electric welding and gas welding; third, during the use process, some heat sources and fire sources should not be close to the steel plate, and a certain distance should be maintained. If you want to set up a kitchen in the sandwich panel room, you need to have a thermal insulation layer, and the wall should be equipped with a fire-resistant rock wool thermal insulation layer; fourth, it is best not to pass the wires and cables through the core material, and protect them if they need to pass through. Bushings, sockets and switch boxes should be made of metal galvanized boxes and installed in the open; fifth, simple fire extinguishing equipment should be equipped indoors and outdoors, and fire alarms should be installed if conditions permit to facilitate rapid evacuation of personnel; sixth, sandwich panels Keep a safe distance of at least 6 meters between rooms.

Although the sandwich panel room sandwich filling material without strict flame retardant treatment is flammable, it will not spontaneously ignite. Strict, scientific and effective management to keep the fire away from the flammable sandwich panel house sandwich filling materials is one of the important ways to prevent the occurrence of sandwich panel house fires.
