Phenolic wall thermal insulation plate burning resistance and application _ langfang three friends of insulation materials co. , LTD
external combustion performance and application of the phenolic insulation board: a, thermal stability,
phenolic wall thermal insulation board in a wide temperature range with good thermal stability, its continuous use in a contraction or cracking temperature range for ℃, with discontinuous use of irradiation temperature can be as high as ℃. Phenolic foam foam components adding fillers can obviously improve the thermal stability, such as join % glass fiber phenolic foam can withstand ℃ high temperature hours without shrinkage or cracking. Phenolic foam used in low temperature is not restricted. These properties are of other organic foam.
for all kinds of all kinds of buildings, to the survival of human security problem is listed in the first. Phenolic foam is a kind of superior performance of fireproof, heat insulation, sound insulation, light energy saving products, plastic bakelite wall thermal insulation board has both of these features, making it the most ideal new organic heat preservation material, very suitable for used as building materials in external wall insulation, roof insulation and fire proof door layer. If we can use phenolic foam exterior insulation materials, can meet the requirements of thermal insulation and fire protection at the same time.
2, and chemical stability of organic materials during the construction and use of equipment and piping heat preservation, sometimes and some solvents and chemicals contact, therefore, need a certain chemical solvent resistance. Phenolic foam chemical resistance, solvent resistance than other organic bubble, in the course of construction and any water soluble, solvent-based glue and glue, wide application range.
3, combustion resistance
phenolic wall thermal insulation plate burning resistance mainly include two aspects, one is the ability to prevent the spread of flame, the partial adiabatic materials produce flame, the flame itself will not spread out; Second, adiabatic performance of material itself, even in burning material side, on the other side of the temperature rises higher and cause fire. Compared with polystyrene foam, polyurethane foam has two characteristics, one is on fire with no dripping phenomenon, 2 it is in the burning compacted carbon forms on the surface, it is to prevent further combustion of the bubble.
French construction science and technology center of phenolic foam comprehensive inspection, prove its good flame resistance, such as up to ℃ temperature from the torch flame on the foam board, minutes haven't record to have apparent thermal to the board on the back, no high temperature pyrolysis and smoke.
