Phenolic insulation board

Features
English name
Its most prominent feature is that it is non-combustible, low smoke and resistant to high temperature variation. It overcomes the shortcomings of the original foam plastic insulation material that is flammable and smokey and deforms when exposed to heat, and retains the characteristics of the original foam plastic insulation material such as light weight and convenient construction.
Phenolic board
Excellent fire resistance
The insulation layer uses phenolic foam and is compounded with other materials for building insulation. It can basically reach the national fire protection standard level and fundamentally prevent the occurrence of external insulation fires. Possibility
, the operating temperature range is ℃ ~ + ℃.
Outstanding thermal insulation and energy-saving effect
Phenolic insulation board has good thermal insulation performance, and its thermal conductivity is about 100%, which is far lower than the commonly used inorganic and organic exterior wall insulation products on the market, which can reach
achieve higher energy saving effect.
Lightweight and non-absorbent
Phenolic insulation board is light in weight, with a bulk density of generally /. At the same time, phenolic insulation board does not absorb water and is not afraid of rain.
Safety and environmental protection
Phenolic insulation board is an environmentally friendly green product. It will not irritate the skin and will not cause any harm to the human body. When burning, it releases non-toxic smoke under limited conditions. It will release formaldehyde exceeding the combustion limit value
Aldehydes, carbon monoxide, etc.
Good dimensional stability
Phenolic insulation board has very good dimensional stability and will not shrink or deform no matter what the environment.
Wide range of uses
Phenolic insulation boards can not only be used in building exterior wall insulation systems, but also in color steel sandwich panels for cold storage in mobile homes, purification workshops, and air-conditioning duct insulation and curtain wall insulation
Warm roof insulation, computer room cabinet insulation equipment insulation, carbon crystal electric heating plate insulation and various areas that require thermal insulation. []
Application editor The thermal conductivity of phenolic foam is about // of polystyrene, and the heat transfer coefficient of polystyrene board is non-flammable and can withstand ℃
High temperature and the price is about the same as polyurethane. Polystyrene foam and polyurethane foam are both flammable, not resistant to high temperatures, and are being restricted by fire departments. Phenolic fireproof insulation board
can effectively solve the problem of building fireproof insulation. Phenolic insulation board does not melt or soften at high temperatures, has low smoke content, does not spread flames, is resistant to flame penetration, has excellent fireproof performance, and
It also has good thermal insulation and energy-saving effects. It combines excellent fire protection performance with good energy-saving effects, and is suitable for external wall insulation. Application form of phenolic insulation board
Building exterior wall insulation thin plastering system insulation decoration integrated curtain wall system
Central air conditioning composite air duct insulation steel surface type phenolic composite air duct double-sided aluminum foil phenolic composite air duct
Color steel sandwich panel field movable board house purification project clean workshop cold storage cabinet machine room, etc.
Roof insulation residential roof factory roof roof insulation brick
Low temperature cryogenic pipeline insulation pipeline Liquefied natural gas pipeline hot and cold Water pipes
Various other fields that require thermal insulation
Phenolic foam materials have been greatly developed since the 1980s. They were first valued by the British and American military and used in the aerospace, aviation, and defense industries, and later were used It is used in places with strict fire protection requirements such as civil aircraft, ships, stations, oil wells, and gradually extended to high-rise buildings, hospitals, sports facilities and other fields [].
Category Edit The defects of polyurethane are easy to burn when exposed to fire, easily produce poisonous gas, and endanger human health
The defects of polystyrene are easy to burn when exposed to fire, shrink after long-term use, and have poor thermal insulation performance
Rock wool glass The defects of cotton harm the environment, breed bacteria, have high water absorption, poor thermal insulation effect, poor strength, and short service life
Advantages of phenolic are non-flammable, no toxic gas and no thick smoke after burning, low thermal conductivity, good thermal insulation effect, sound insulation, and weather resistance Good thermal stability and service life of up to 10 years
It has a uniform closed-cell structure, low thermal conductivity and good thermal insulation performance, which is equivalent to polyurethane and better than polystyrene foam
It has a wide applicable temperature range and can be used in the short term It can be used at ℃ ~ ℃, and can be used for a long time at ℃ ~ ℃, which is better than polystyrene foam ℃ and polyurethane foam
℃
Phenolic molecules only contain carbon, hydrogen and oxygen atoms, and when subjected to high temperature decomposition , except for producing a small amount of gas, no other toxic gases will be produced, and the maximum smoke density is
. After the thick phenolic foam board withstands flame spray at ℃, the surface is only slightly carbonized but cannot be burned through. It will neither catch fire nor emit thick smoke and poisonous gas
In addition to being corroded by strong alkali, phenolic foam It can resist the erosion of almost all inorganic acids, organic acids and organic solvents. There is no obvious aging phenomenon when exposed to sunlight for a long time
, so it has good aging resistance
The cost of phenolic foam is low, only equivalent to two-thirds of polyurethane foam. []
Structure editor The system structure of phenolic insulation board mainly consists of bonding layer, insulation layer, plastering layer, facing layer and accessories.
The bonding layer belongs to the building and is between the bottom layer and the surface layer. It mainly uses cementitious materials to firmly bond the upper and lower layers together, and its filler mainly comes from inorganic substances.
In order to prevent and reduce the heat loss of the steam turbine to the environment, the insulation layer is a layer of thermal insulation material laid on the outer surface of the steam turbine and pipelines. Its main filler is rock wool fiber and a certain amount of organic matter, moisture, There are also adhesives, etc.
The facing layer should use light functional coatings such as facing mortar or decorative mortar or water-based exterior wall coatings with excellent breathability. This allows the phenolic board to maintain its lightweight characteristics and also increases
of its beauty.
Accessories mainly use various types of coatings. On the one hand, they increase the color of the surface of the phenolic board so that it can be suitable for any environment. The coatings can also play a role in flame retardancy and heat preservation to a certain extent
