Phenolic insulation board quality

At present, the quality of phenolic insulation board was caused by fire insulation materials, caused the personnel casualty and property, caused huge losses to people's life. Traditional phenolic board not only can be used for exterior insulation system, can be also prepared to act the role of surface composite insulation decoration plate, can also be used to build the traditional EPS/XPS/fire belt, PU external wall insulation system will be used for fire prevention in the curtain wall insulation insulation materials, fire door insulation materials, as well as low or high temperature fire insulation thermal insulation material. Phenolic insulation board with phenolic resin and flame retardant and smoke suppression agent, curing agent, foaming agent, and other additives, and other material, through scientific formula of closed groove rigid foam, phenolic insulation board in the areas of application: due to the flammable polystyrene foam and polyurethane foam, not high temperature resistant, Chiang kai-shek in some industrial developed country restrictions on use by the fire department, strict in fire protection, government departments have clear stipulation can only use phenolic insulation board. Therefore, phenolic foam material is more suitable for have strict requirements under the environmental conditions of use of high-performance materials, has a good development prospect. Phenolic insulation board production convenient, can according to user needs in site construction; Cleaning and hygiene; Using aluminum foil composite sandwich board surface, ensuring the health of air from the duct, the frictional resistance is small, the air quality is high, because the product is called environmental duct. Because the product is made up of aluminum foil ﹢ phenolic foam ﹢ aluminum foil, and therefore has a good sound insulation, vibration resistance dimming and flame retardant, energy-saving features, to reduce the operation cost. Therefore, when choosing insulating material, must pay attention to observe the quality of the insulation board, so how to distinguish between the quality of the phenolic insulation board? Phenolic insulation board as a kind of exterior wall, is also a kind of external wall insulation. When choosing insulation materials should pay attention to? Production is made of foam production, this method is commonly used in the production of the product density is relatively low, brittle, and prone to powder or slag. 2. The other is the assembly line production, is used to protect modified phenolic plate temperature. Improved phenolic resin and foaming process, to a certain extent, produced a modified phenolic insulation board, overcome the shortcomings of their shattered slagging. The density of modified phenolic insulation board in more than 55 kg. 3. In addition to the above method, to observe the appearance of the phenolic insulation board, press the hand, the density of breaking it to observe the toughness of the insulation board, rubbing to identify the quality of the phenolic insulation board. 4. In addition to purchase insulation board must choose normal manufacturer purchase, because this kind of normal manufacturer, they are controlled by strict quality supervision department. This kind of formal manufacturers product quality problem is relatively small. 5. Phenolic insulation board should be paid attention to the construction of a corner, to ensure the integrity of the wall when the.
