What is Phenolic ductwork and its advantages?
Modified phenolic formaldehyde is made of non-woven fabric and phenolic formaldehyde through continuous compounding and compounding, and it is compounded and compounded. It is a material, the middle phenolic foam is guaranteed to be foamed and foamed, the density of the cells, the cells and the foaming density are even, flat, non-absorbent, light, and composited with color steel to make a color steel sandwich fermentation paste board.
Phenolic foam is known as the "King of Insulation". It was used in the insulation of missiles and rocket heads in the early days. It has become the fastest growing variety of plastics in some developed countries such as the United States, Britain, and Japan. Phenolic foam material has good flame retardancy, small thermal conductivity, excellent sound absorption performance and long service life. Due to the above superior characteristics, phenolic foam materials have been widely used in various aspects of the national economy, such as central air-conditioning ducts, hot and cold transmission pipes, clean workshops, shopping malls, light-weight quick-loading rooms, cold storage, refrigerated trucks, airplanes, Ships, hotels and entertainment boxes, etc. need to use fireproof, light weight, heat preservation, sound insulation, clean, moisture-proof materials.
Performance advantages of phenolic composite air duct
The traditional air supply duct of central air conditioner is usually made of iron sheet or fiberglass as the inner layer, wrapped with thermal insulation material, and wrapped with aluminum foil on the outside, which makes the air supply duct heavy in weight, labor-intensive and time-consuming in construction and installation, poor in appearance, low in air tightness, and low in energy consumption. big. Compared with traditional air ducts,
Phenolic ductwork has following good features:
1. Noise reduction.
The interlayer of the phenolic aluminum foil composite air duct wall is a porous phenolic foam material plate that penetrates each other, which has good noise reduction performance. In the central air-conditioning system, the noise generated by the air-conditioning unit during operation is in the range of 50-79dB, which is transmitted through the air supply pipe to form indoor noise. The phenolic aluminum foil composite air duct itself is a very good pipe muffler, and there is no need to set up muffler accessories such as muffler covers and muffler elbows.
2. Low thermal conductivity.
It can greatly reduce the heat dissipation loss of the air conditioner. The thermal conductivity of phenolic composite air duct is 0.016~0.036W/(m·k), while the thermal conductivity of galvanized steel air duct and glass fiber reinforced plastic air duct is much larger. In addition, the unique connection method of the phenolic composite air duct ensures the excellent air tightness of the ventilation system, which is close to 8 times that of the galvanized steel air duct. Some data show that when transporting the same amount of heat (cold), the heat dissipation loss of the galvanized steel air duct is 15%, the heat dissipation loss of the glass fiber reinforced plastic air duct is 8%, and the heat dissipation loss of the phenolic foam insulation material air duct is less than 2%.
3. Light in weight.
It it able to reduce building load, and easy to install with its light weight feature. The phenolic duct panel is light in weight, about 1.4 kg/㎡, while the density of galvanized steel air duct (0.8mm thick) and FRP air duct (3 mm thick) are 7.08 kg/㎡ and 15~20 kg/㎡ respectively. ㎡, which can greatly reduce the load of the building, and is extremely beneficial to the installation of air ducts. When installing, it only needs to set up a bracket every 4 m or so to have enough supporting force. This greatly reduces the requirements on the bearing capacity of brackets, hangers, etc., making transportation and installation very convenient. Using a phenolic duct making machine is the best choice to improve your Phenolic ductwork efficiency. Phenolic duct making machine is a cnc duct making machine used to make Phenolic ductworks. If you search for a phenolic duct making machine, please make sure that the phenolic duct making machine has a dedicated phenolic duct making software that is easy to use, and comes with a graphic gallery. Phenolic duct making machine with a phenolic duct making software is much more user-friendly.
4. Durable and long service life
Galvanized steel sheets are prone to rust in humid environments, while glass fiber reinforced plastics are prone to aging and damage. Therefore, the service life of traditional air ducts is not long, about 5 to 10 years. The insulation layer of traditional air ducts, such as glass wool The service life is only 5 years, while the service life of the phenolic aluminum foil composite air duct is at least 20 years. Therefore, the service life of the phenolic aluminum foil composite air duct is more than three times that of the traditional air duct. In addition, the reuse rate of phenolic aluminum foil composite air duct can reach 60%~80%, while the traditional air duct can hardly be reused.
5. Reduce layer height
Traditional air ducts require on-site insulation layer construction, so a certain construction height is required, which puts additional requirements on the building's storey height. The phenolic aluminum foil composite air duct does not require on-site insulation construction, so there is no need to reserve construction space, which can reduce the height of the building.
