Phenolic foam wall insulation material as imperative
According to experts, the current closure of phenolic foam material and to control the fire as the building external wall insulation quality has been widely put into use in foreign countries.
HC Building Network Energy Not fire, wall insulation materials frequently "hot." So, looking for a fireproof insulation both, but also a very small impact on human health Building Insulation material, on the part of the solution "insulation" key to the problem.
Thermal insulation material specialists, Jinan University Chemistry Chemical industry Professor Liu Wei of that from domestic and international use of the existing practice of building insulation materials, use phenolic foam as the building's exterior wall materials, can play safety and energy saving "double insurance" effect. Good heat resistance of phenolic foam, phenolic foam 25 mm thick plate withstand the flames of 1700 for 10 minutes after injection, only slight charring the surface and will not be burn, can effectively prevent the fire and the fire spread. It is worth mentioning that in the fire, most casualties are due to fire smoke and toxic gas caused by the scene, but the phenolic foam is high even if ignited, its combustion and no drip, low smoke, and almost does not produce carbon monoxide and other toxic gases.
According to experts, the present phenolic foam Building Materials Closed and control the fire as the building external wall insulation quality has been widely put into use abroad. Phenolic materials abroad many times to visit Jinan Quan briefed reporters chairman Tang Yilin, France Marseille, Lyon and other cities built many large apartments, has been installed outside the wall phenolic foam, then coated with protective layer to prevent the fire burning spread. Government of Japan is introduced legislation to phenolic foam as a fire retardant material standard of public buildings, in other words, anti-burning properties than phenolic foam, does not allow the use of public buildings. In China, although the use of phenolic foam insulation produced air duct system has been in the "Water Cube", Beijing subway construction and other public buildings to get high use, but not yet issued as phenolic foam used as the building's exterior wall materials, specifications, now Phenolic foam wall construction of civil buildings in China are also rarely used.
Are needed for policy, technical follow-up. Building's exterior wall material for the current existence of a major security risk, experts suggest that as soon as possible to formulate recommendations phenolic foam as exterior wall material specifications, and conduct research using pilot projects and technologies, progressive, public and civil "double-effect energy-saving and security" .
As a safe, green new Building Materials , Phenolic foam advantage of more and more industry recognition, but not by the state included in the building's exterior wall materials recommended range of phenolic materials in building design makes the link "has been eliminated." States should as soon as phenolic foam as exterior wall materials recommended to develop the appropriate technical standards and norms of production, and select high-rise buildings and large-scale construction of public buildings pilot, and then gradually extended to civil and Transportation .
