Youshi phenolic composite duct
The middle layer of the super fit phenolic composite air duct is phenolic foam, and the inner and outer layers are made of embossed aluminum foil.
Phenolic resin is the earliest industrialized plastic product in the world, and the excellent brand phenolic foam is a newly developed variety in recent years. Phenolic foam is known as "the king of heat preservation". The excellent brand phenolic foam material has good flame retardancy, small thermal conductivity, good sound absorption property and long service life. Because phenolic foam has the above advantages, it has been widely used in various aspects of the national economy, such as central air conditioning duct, cold and hot conveying pipeline, clean workshop, shopping mall, light body fast loading room, cold storage, refrigerated vehicle, aircraft, ship, hotel and entertainment box, etc. it is necessary to use fireproof, light weight, heat insulation, sound insulation, clean and moistureproof materials.
The composite phenolic foam board is made of sandwich panels with aluminum foil, and then the phenolic composite air duct made of special flange fittings is used for central air conditioning ventilation. The inner and outer surface of the excellent brand phenolic composite sandwich panel is coated with aluminum foil, and the middle layer is phenolic foam material. Its comprehensive properties have been greatly improved, especially in terms of mechanical properties, such as bending resistance, compressive strength, brittleness and processability.
1、 Performance advantages of Youshi phenolic composite duct
The traditional air supply duct of central air conditioning is usually made of iron sheet or glass fiber reinforced plastic, wrapped with thermal insulation material and wrapped with aluminum foil at the outside, which makes the air supply pipe self heavy, construction and installation time-consuming, poor appearance, low air tightness and high energy consumption. Compared with traditional duct, Youshi phenolic composite duct has the following advantages:
1. Good heat insulation, can greatly reduce the heat loss of air conditioning
The thermal conductivity of Youshi phenolic composite duct is 0.016 ~ 0.036w / (m · K), while the thermal conductivity of galvanized steel duct and FRP duct is much higher. In addition, the unique connection mode of Youshi brand phenolic composite air duct ensures the excellent air tightness of the ventilation system, which is 8 times of that of galvanized steel duct. Data show that when the same heat (cold) is applied, the heat loss of the galvanized steel tube is 15%, and the heat dissipation loss of the FRP duct is 8%. The heat dissipation loss of the wind pipe of the superior brand phenolic foam insulation material is less than 2%.
2. Good noise elimination.
The interlayer of the composite air duct wall of the well suited brand phenolic aluminum foil is a porous phenolic foam board with mutual penetration, and has good sound attenuation performance. In the central air-conditioning system, the noise generated by the air-conditioning unit is in the range of 50-79 dB, which is transmitted through the air supply pipe, forming the indoor noise. Yushi phenolic aluminum foil composite air duct itself is a good pipe muffler, no need to set anechoic cover and muffler elbow and other anechoic accessories.
3. Light weight, can reduce the building load, and easy to install
The weight of Youshi brand phenolic aluminum foil composite air duct is light, about 1.4 kg / m2, while the unit weight of galvanized steel duct (0.8mm thick) and FRP duct (3 mm thick) are 7.08 kg / m2 and 15-20 kg / m2 respectively, which can greatly reduce the building load and is very beneficial to the installation of air duct. When installing, it is only necessary to set up a bracket every 4 m to have enough supporting force. This greatly reduces the requirements for the bearing capacity of supports and lifting parts, which makes transportation and installation very convenient.
4. Durable and long service life
Galvanized steel sheet is easy to rust in humid environment, while glass fiber reinforced plastic is easy to be aged and damaged. Therefore, the service life of traditional air duct is not long, which is about 5-10 years. The service life of thermal insulation layer of traditional air duct, such as glass wool, is only 5 years, while the service life of optimal phenolic aluminum foil composite air duct is at least 20 years. Therefore, the service life of Youshi brand phenolic aluminum foil composite air duct is more than 3 times of that of traditional air duct. In addition, the reuse rate of Youshi brand phenolic aluminum foil composite duct can reach 60% ~ 80%, while the traditional air duct can hardly be reused.
5. Reduce the floor height
The traditional air duct needs insulation layer construction on site, so it requires a certain construction height, which puts forward additional requirements for the floor height of the building. Therefore, there is no need to reserve construction space, which can reduce the height of the building.
6. It can shorten the construction period
The weight of Youshi phenolic aluminum foil composite air duct is very light, and its installation is more convenient and faster than that of traditional air duct. When the air duct is hoisted, the hanger is simple, the quantity is small, and almost no machinery is needed. The production is simple, completely breaking through the traditional technology, greatly shortening the construction period, and site modification is also very convenient. According to the field calculation, each worker can install 20.0-30.0 square meters per day during the installation of phenolic aluminum foil composite air duct, while the traditional air duct is only 4.0-5.0 square meters per day per person. Compared with the traditional air duct manufacturing, the production efficiency of Youshi brand phenolic aluminum foil composite air duct is increased by 4-5 times.
7. Hygiene
The surface of Youshi phenolic aluminum foil composite air duct is sealed with aluminum foil, so as to ensure the sanitation of conveying medium, avoid secondary pollution, and the inner layer has no condensation water and rust. In the traditional air duct, glass wool and asbestos are easy to absorb moisture, and the thermal insulation performance deteriorates seriously after absorbing water. Moreover, asbestos is a carcinogen. Glass wool dust can stimulate the skin and make construction workers itch all over. In addition, galvanized steel duct is easy to rust, and easy to produce cold bridge phenomenon.
8. Beautiful, suitable for surface decoration.
Youshi brand phenolic aluminum foil composite duct can be made into various colors, beautiful, especially suitable for surface mounting. The surface of traditional air duct needs to be wrapped with aluminum foil on site, so the surface mounting effect is not very good.
9. Wide application scope
Galvanized steel air duct shall be
