Phenolic insulation board of technical transformation mainly includes: one is the use of advanced automation equipment complete molding and modification of phenolic insulation; The second is in the process of phenolic resin production by chemical or physical modification to complete the modification of phenolic insulation board. Phenolic plate is a new kind of non-combustible low smoke, fire insulation materials, it is made of phenolic resin in foaming agent, curing agent and other additives made of closed-cell rigid foam. It is the most prominent feature of non-combustible, low smoke, resistance to high temperature of different change. It overcomes the original type foam insulation material inflammable, cigarettes, drawback of the metabolic that encounter heat, retained the original type foam insulation material is qualitative light, construction is convenient wait for a characteristic. 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 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. Third, use compound phenolic insulation board outside non-combustible material to modification of phenolic resin board, fire resistance rating reached A level, the disadvantage of polyurethane is easy ignition, easy to produce poisonous gas, damage to human body health. 2. Polystyrene defect is vulnerable to fire, will be shorten the period of time, insulation performance is poor. 3. Rock wool and glass cotton shortcomings are: damage to the environment, breeding ground for bacteria, bibulous rate is high, the heat insulation effect is poor, poor strength and short service life; Phenolic advantages: no flammable, do not produce poisonous gas and smoke after burning, good thermal conductivity, insulation performance is good, the weather is good, life can be up to 30 years; The pore structure of uniform, low thermal conductivity, insulation performance is good, suitable for polyurethane, is better than that of polystyrene foam; Appropriate temperature scale is big, can be used in the short term - 200 ℃ ~ 200 ℃, can be used in the 140 ℃ ~ 160 ℃, for a long time is better than that of polystyrene foam plastic ( 80℃) And polyurethane foam ( 110℃) 。 Phenolic insulation board not only can be used for building exterior wall insulation system, can also be used for mobile room, purifying workshop, caigang sandwich plate refrigerator, air conditioner, pipe insulation, wall insulation, roof insulation, cabinet insulation, insulation, carbon crystal insulation of equipment and all kinds of insulation class.
