Phenolic insulation board the quality requirements
China because of the heat preservation material caused by fire and anesthesia, and the frequency and personnel industrial limit to lose. Across the insulation market, throughout the use of thermal insulation materials mainly of polystyrene, extruded polystyrene board, polyurethane foam, etc. The biggest question in the thermal insulation material, it is fire prevention function is poor, even the welding of Mars, also can make the heat preservation material on fire.
these burned heat preservation material, and many toxic smoke melting drop occurs, not only brings environmental pollution, fire rescue work to bring huge inconvenience, and endanger the life safety of the residents and firefighters. For this, on September 25, 2009, the Ministry of Public Security, housing and urban-rural development jointly drawn up the civil building external thermal insulation system and external wall decoration interim rules on fire protection, this paper rules: civil building height is greater than or equal to 100 m, other civil construction is greater than or equal to 50 meters, building curtain wall type is higher than 24 meters, the function of heat preservation material incineration should be A level; Less than the height, shall establish fire belt. It brings to the domestic manufacturer of phenolic infinite market, at present domestic has been put into production or under construction of phenolic foam production factory for more than a dozen. http://www。 juanzhibwb。 com
