Phenolic insulation board is not only insulation, sound absorption and sound insulation effect is very good also

Due to the effect of insulation of the high quality, phenolic insulation board got the favour of many users, but phenolic insulation board effect of sound absorption and sound insulation effect are rarely discussed, in fact, phenolic insulation board is not only insulation, sound absorption, sound insulation effect is very good also. 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. The main raw material of phenolic insulation board is phenolic foam, phenolic foam itself is a kind of very good sound insulation materials. Phenolic insulation board, therefore, not only has light weight, small coefficient of thermal conductivity, not burning, etc, and has a good sound absorption and sound insulation performance, but also to the national standard of phenolic insulation board coefficient have clear requirements and definitions. This is phenolic insulation board in the external wall insulation system is widely used as the cause of the absorption material. Phenolic insulation board in the external wall insulation system, then, what are the principles in?
in fact, the optical properties of phenolic insulation board and phenolic insulation board sound-absorbing function can use phenolic insulation board, light wall of sound insulation system is the outer walls of buildings. 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. External wall insulation system of typical structure to a + + + keel phenolic board plasterboard plasterboard. Sound insulation effect is the main phenolic insulation board, it absorbs part of the sound waves through the plasterboard, reduce the sound waves in the cavities formed between the plasterboard, keel and gypsum board of reflection. In order to achieve increased wall sound insulation function. By the professional test instrument, adding phenolic insulation board in the external wall insulation system of exterior wall sound insulation effect is higher than without phenolic insulation board of plasterboard 8 ~ 15 db.
should be paid attention to, phenolic insulation board in the construction process of easily crushed due to improper operation or cracking. In the external wall insulation system, therefore, should pay attention to the construction technique of phenolic insulation board, in addition, because of the characteristic of the phenolic foam, usually buy phenolic insulation board often occurs pulverization and embrittlement phenomenon. But the only way to solve this problem is to buy a fairly thick phenolic insulation board. Phenolic plate thickness, however, it is easy to fall off, because phenolic board quality is more important in the external wall insulation system, therefore in the construction of exterior wall insulation system, should pay special attention to the thickness of the phenolic insulation board and construction process.
