Phenolic composite air duct structure: the middle layer is phenolic foam insulation layer, and the inner and outer layers are embossed aluminum foil, which is formed in one step. Phenolic foam is the earliest industrialized plastic foam product in the world, and phenolic foam is a newly developed and successfully applied variety in recent years. Phenolic foam board is known as the “king of thermal insulation materials” in the industry. It was early used in the thermal insulation of various high-end technology industries. Phenolic foam board has become one of the fastest growing varieties of foam board in some developed countries. Phenolic foam material has the advantages of high flame retardancy, excellent sound absorption, small thermal conductivity and long service life. Because of the above superior characteristics, phenolic foam materials have been widely used in various industries, such as cold and hot transmission pipelines, central air conditioning ducts, clean workshops, shopping malls, light body fast loading rooms, cold stores, refrigerated trucks, aircraft, ships, hotels, entertainment venues, and other places where thermal insulation, fire protection, light weight, sound insulation, cleaning, moisture-proof materials are needed. The phenolic foam plate is compounded with embossed aluminum foil to form a composite plate, and then added with special flanges, glue and other accessories. The phenolic composite air duct is used for central air-conditioning ventilation, fresh air duct and fan coil unit. The internal and external surfaces of phenolic composite air duct plate are embossed aluminum foil or color steel, and the middle layer is phenolic foam material. The embossed aluminum foil is called aluminum foil phenolic composite air duct plate, and the color steel is called phenolic color steel composite air duct. Its comprehensive performance has been greatly improved, especially in mechanical properties, such as compression resistance, bending resistance, brittleness, and processing performance, Basically meeting the requirements for the use of central air conditioning ventilation ducts and fresh air ducts.
Product features:
1. The phenolic air duct board itself is made of light material; Phenolic composite air ducts can reduce building loads and are easy to install: the weight of phenolic composite air ducts is light, about 1.4gk/m3, which can greatly reduce building loads and is extremely beneficial for the installation of air ducts.
2. Good insulation performance; Phenolic compound air duct can greatly reduce the heat loss of air conditioning: when conveying the same heat (cold) amount, the heat loss of galvanized steel duct is 15%, that of glass fiber reinforced plastic duct is 8%, and that of phenolic foam insulation material duct is less than 2%.
3. Long service life and durability; Galvanized steel plates are prone to rust in humid environments. Fiberglass is prone to aging and damage. The service life of phenolic composite air ducts is more than three times that of traditional air ducts.
4. The finished air duct is aesthetically pleasing and suitable for both exposed and concealed works; Phenolic composite air ducts can be made into various colors, which are aesthetically pleasing and particularly suitable for surface decoration. The surface of traditional air ducts requires on-site aluminum foil wrapping, so the surface installation effect is not very good.
5. Reduce the requirements for building height and ensure flexible production; Traditional air ducts require on-site insulation layer construction, therefore requiring a certain construction height, while phenolic composite air ducts do not require on-site insulation construction, which can reduce the height of the building.
6. The air duct has good soundproofing; The sandwich of phenolic composite air duct wall is made of porous phenolic foam material plate, which has good noise elimination performance. This makes the phenolic aluminum foil composite air duct itself a tubular muffler, and it is unnecessary to set noise elimination covers, noise elimination elbows and other noise elimination accessories.
7. Suitable for various types of central air conditioning ducts; Galvanized steel sheet air ducts have a low lifespan in high humidity environments, while fiberglass air ducts are limited in areas with dust prevention requirements and high humidity. Phenolic composite air ducts can be widely used in industrial and civil buildings, hotels, hospitals, and other places with special requirements.
8. The air duct itself has good cleanliness and clean air quality; The surface of the phenolic composite air duct is sealed with aluminum foil, ensuring the hygiene of the conveying medium, avoiding secondary pollution, and the inner layer is free from condensation and rust.
9. The production and installation of air ducts can shorten the construction period; Phenolic composite air ducts are lightweight and easier to install than traditional air ducts. Compared with traditional air duct manufacturing, the production efficiency of phenolic composite air ducts has been improved by 4-5 times.
(1) Can shorten the construction period: The phenolic aluminum foil composite air duct is lightweight and easier to install than traditional air ducts. When lifting the air duct, the required hangers are simple, with a small quantity and almost no need for machinery. The production is simple, completely breaking through traditional techniques, greatly shortening the construction cycle, and on-site modifications are also very convenient. According to on-site calculations, during the installation of phenolic aluminum foil composite air ducts, each worker can install 20.0-30.0 square meters per day, while traditional air ducts only have 4.0-5.0 square meters per day per person. Compared with traditional air duct manufacturing, the production efficiency of phenolic aluminum foil composite air ducts has increased by 4-5 times.
(2) Hygiene: The surface of the phenolic aluminum foil composite air duct is sealed with aluminum foil, ensuring the hygiene of the conveying medium, avoiding secondary pollution, and the inner layer is free from condensation and rust. In traditional air ducts, glass wool and asbestos are prone to moisture absorption, and their insulation performance severely deteriorates after absorbing water. Moreover, asbestos is a carcinogen, and glass wool dust can irritate the skin and make construction workers itch all over. In addition, galvanized steel duct is prone to rusting and cold bridging.
(3) Beautiful, suitable for surface decoration: Phenolic aluminum foil composite air ducts can be made into various colors, beautiful, especially suitable for surface decoration. The surface of traditional air ducts requires on-site aluminum foil wrapping, so the surface installation effect is not very good.
(4) Wide application range: Galvanized steel sheet air ducts are widely used, but their service life is low in high humidity environments. Glass fiber reinforced plastic air ducts have dust prevention requirements and are also limited in high humidity places such as hospitals, food processing plants, and basements. Phenolic aluminum foil composite air ducts can be widely used in industrial and civilian buildings, hotels, hospitals, office buildings, and other special requirements places
