The history of phenolic insulation board _ langfang three friends of insulation materials co. , LTD
the history of the development direction of exterior wall thermal insulation material macro & ndash; — New building insulation materials research and development is as important as wall thermal insulation system design, safety and energy saving, thermal insulation and fire prevention in the first place, therefore phenolic insulation board appearance has attracted much attention and affirmation.
according to the statistical data and literature, the % of fire insulation sound insulation materials for phenolic resin; Britain, Western Europe, the Middle East new construction preferred phenolic foam insulation materials; France, department of architecture of northern Europe believe that only phenolic foam insulation materials has good fireproof performance; Russia and eastern Europe is also widely use phenolic foam insulation materials for public buildings and high-rise buildings; Even Japan promulgated the phenolic foam as standard building fire resistant materials. In order to improve the fire resistance performance, the domestic enterprise research and development of composite phenolic foam ( PF) Plate by the national fireproof construction material quality supervision inspection center of detection, its combustion performance level GBA. This suggests that the phenolic foam ( PF) As a kind of safe, green new energy-saving building materials, its advantage has got the construction department and the public security fire department approval.
it is known that phenolic foam insulation of early application in missile and rocket head. In recent years because of the high-rise building, transportation, ships, aviation, space technology and so on synthesis of foam plastic, thermal stability and flame resistance is put forward strict requirements, as a new type of multi-purpose foam material, it besides can reach other insulation material can reach the effect of heat preservation, is also a good fire safety material, light capacity, good insulation, good rigidity, dimensional stability, and it is similar to aluminium expansion coefficient, belong to the flame retardant material, produces only a small amount of carbon monoxide poisonous gas when burning, smoke quantity is low, will not melt, without dripping, lower the production cost. Therefore, phenolic insulation board is widely used in developed countries.
phenolic foam ( PF) Low thermal conductivity, compared with the traditional heat preservation material more than double that of its energy-saving insulation performance, there are even & other The king of the heat preservation & throughout; Or & other The third generation of heat preservation material & throughout; The reputation. The United States, Japan and other developed countries are strict fire prevention requirements for wall heat preservation, in recent years, countries are turning to both energy saving and fireproof PF, used in wall insulation system.
