Phenolic insulation board PK all kinds of insulation performance of phenolic insulation board
who is heat preservation industry a bully? Phenolic insulation board, began to enter the construction market has caused the great attention of many businessmen and consumers, phenolic insulation board is what characteristics favored by the consumers and businesses? The following will talk about phenolic insulation board together with all of you PK performance comparison of various kinds of thermal insulation material.
。 Phenolic foam cost is low, only about two-thirds of the polyurethane foam;
。 Phenolic foam, except may be strong alkali corrosion resistance can almost all inorganic acid, organic acid, organic solvent. Long-term exposure to sunlight, no obvious aging phenomenon, thus has good aging resistance;
。 Phenol molecules contain only carbon, hydrogen, oxygen, by pyrolysis, in addition to produce a small amount of CO gas, won't produce other toxic gases, the most great smoky density of. %。 Mm thick phenolic foam plate after being ℃ flame spraying min, only slightly carbonization is don't wear surface, neither fire nor send out smoke and poisonous gas;
。 Suitable temperature range is big, in the short term can be used under ℃ ~ ℃, can use for a long time under ℃ ~ ℃, is better than that of polystyrene foam ( ℃) And polyurethane foam ( ℃) ;
。 Obturator structure of phenolic insulation board is uniform, low thermal conductivity, good thermal insulation performance, polyurethane and its better than polystyrene foam;
。 Phenolic advantages: non-combustible, no gas and smoke after burning, low thermal conductivity thermal insulation effect is good, sound insulation, weather is good, service life can be for years;
。 Rock wool, glass wool defects: bad for the environment, the breeding ground for bacteria, bibulous rate is high, poor heat insulation effect, strength is poor, short service life;
。 The defects of polystyrene: meet the fire burning, with long will shrink, heat preservation performance is poor;
。 The defect of polyurethane (pu) : meet fire burns easily, is easy to produce poison, harm human health;
just single phenolic insulation board with various insulation board for the professional product performance PK, believe that everyone is watching the results can understand why phenolic insulation board is so popular, believe the future heat preservation industry bully, easy!
