so extruded plate as combustion-supporting agent
Shanghai teachers apartment fire, Shenyang Royal Wan Xin mansion......A beautiful building became a black coke louboutin outlet, countless life is suddenly engulfed riesengro.While the fire is one of the reasons, because XPS Extrusion board lost their flame retardant properties led to the fire spread.

■ report such a low price of plastic extrusion plate, the absolute quality problem
"such a low price of the extrusion plate, the absolute quality problems hollister uk."On March 6th, at a construction site for the construction of Li engineer reflects something he abnormal surprised phenomenon: at present, the market sales of new building materials plastic extruding plate, the same specifications of products but the price difference of nearly three into.Moreover, countries have mandatory standard building materials, manufacturers can also be in accordance with the requirements of "lower prices and production standards" woolrich outlet;."A fire was burning with.I suspect that the fake flame retardant board because Jerry is not up to standard, flame retardant."
XPS XPS extruded polystyrene is our country in recent years popularization and application of new building materials, the use of waste plastics recycling of new environmental protection materials, because of their superior high strength, compressive strength, excellent thermal insulation property, light texture hollister, easy to use, high-quality water repellency, moisture resistance and environmental performance, stability, corrosion protection well, the construction industry to become widespread promotion of new building materials.Widely used for wall and floor insulation hollister.
so extruded plate as combustion-supporting agent
Lee engineer reflect the situation if it is true, so he opened a shaking inside moncler.
in accordance with national standards, the name is called adiabatic extrusion plate with extruded polystyrene foam abercrombie, thermal insulation, fire retardant, compressive strength, environmental protection and other effects is the most important function, the current national standard GB8624 "building materials products classification for burning behavior of rules:" B2 is now XPS Extrusion board minimum flame retardant oxygen index ≥ 26.According to the "law of the people's Republic of China fire" Eleventh rules "of building components and building materials fire performance must conform to the national standards and industry standards" requirement, extruded board in the production process needs adding a flame retardant, to prevent and delay the polystyrene plate burning.
according to Lee engineer introduction, at present, the thickness is 2 to 10 centimeters of the extrusion plate, generally in the building external wall surface with a special adhesive bonded to the substrate, the lateral flame-retardant glass fiber network and cement mortar protective layer "a seamless heavenly Robe" wrapped a layer, form the outer wall heat preservation system.That is to say, at present, a lot of under construction buildings are made of extruded board insulation, heat insulation, from a to Z in a layer of light "insulation coat".
building exterior wall flame-proof "insulation coat", but because the builders "Jerry", into the fire that is burning and difficult to fight "invisible bomb" doudoune moncler;.In recent years, the construction industry of new building materials insulation extruded boards (known as the heat-insulating plastic-extruding polystyrene foam), is a country the new energy-saving materials.In order to "reduce the building cost", some construction companies cut corners, extensive use of without flame retardant " louboutin pas cher;Cape plate", "leading to the building thermal insulation coat" hollister; into combustible hollister milano.This use of " hollister;hidden bombs" profiteering illegal behavior, has become a Lanzhou building materials market half open secret.
Extrusion board "to see the fire that is burning", that means the building fully equipped this layer "insulation coat" become very dangerous "combustion bomb".
