subject: Beijing Polyurethane Core Material Such As Temporary Housing Standard Color Plate Forthcoming - [print this page] Plastic plate Material HC plastic mesh Recently Guangqumen 1 Hotels Color plate houses on fire, to draw lessons from the accident, city Fire Bureau yesterday said it would carry out special operations control color steel construction. At present, the fire department has also conducted preliminary research joint Municipal Construction Commission, preparing and local standards related measures introduced to enhance the color steel temporary construction of housing management.
Recent years, the city building construction site and temporary construction buildings fire disaster, especially in color plate marked increase in building fires. According to statistics, last year the city a total of 126 color plates of fire, fire in the first quarter of this year, since 65 such fires the situation worse.
Material from the color of steel, color coated sheet steel to the surface materials, core materials mainly Polystyrene , Polyurethane, rock wool of three. Currently, the city most of the color plate for the polystyrene and polyurethane insulation materials. Although these materials are light weight, low cost, simple operation and other advantages, but the lighting is very low, and poor fire-retardant.
Ignition of polystyrene is 346 , only higher than the burning of wood, polyurethane burning only about 130 , such as ordinary paper. Polystyrene and polyurethane in the combustion will generate a lot of smoke, its composition is mainly carbon monoxide, hydrogen cyanide and other toxic gases.
"As combustion of color plates are 'chimney fire', that is, internal combustion, fire fighting can only hit the outside through the water on the cooling plate, not directly fighting the fire point, greatly affected the rate of fire and steel easy to collapse Firemen difficult to rescue the house property. "Fire experts said frankly that the fire department currently no effective way to fight the fire color plate. In addition to its own defects
color plates, the construction unit in the installation and use of illegal operations during a fire is a major factor. Color plate housing build process, polystyrene, polyurethane is exposed state, easily welding, gas welding, flame cutting machines and other operating direct ignition; color plate housing into use, the random wiring, near heat, fire, and also easily ignition of polystyrene or polyurethane sandwich.
Now on, the fire department will carry out the construction site of the city's temporary housing and color steel insulation special management action, governance includes the construction site of the city built in the construction of the color plate housing, and construction of the main clinical use of thermal insulation material. Governance process, the fire department will build temporary housing color plate material, fire safety, fire prevention space, security, evacuation and other specific requirements. Through the special rectification, control the city's temporary housing and color steel insulation fire safety conditions and urge the rectification fire hazard.
In addition, the fire department jointly with the Urban Construction Commission investigation, preparation and local standards related measures introduced to enhance the color steel temporary construction of housing management, strengthen the material, construction, management, measures to prevent such fires.
