Aluminum foil phenolic air duct board and color steel phenolic air duct board are both made of phenolic resin as raw material, with aluminum foil or color steel composite on both sides, and are formed by advanced fully automatic production lines through one-time foaming and composite molding. The air duct system made of this material has low air friction resistance, low thermal conductivity, high bending strength, excellent insulation performance, and can reduce cooling loss. The embossed aluminum foil on the inner and outer layers of the aluminum foil phenolic air duct is treated with a special process to form a stable and dense protective layer, with a service life of over 20 years. The double-sided aluminum foil phenolic composite air duct adopts the sandwich structure principle. The middle layer is closed cell phenolic foam, and the upper and lower layers are covered with a layer of embossed aluminum foil. The double-sided aluminum foil phenolic composite air duct (aluminum foil pattern and treated with anti-corrosion coating; with noise reduction effect, more hygienic, and corrosion-resistant) forms a sandwich panel of sandwich style, with innovative design that greatly reduces noise; And it can maintain stable temperature, humidity, and air quality components, which can meet the needs of various places of use. The double-sided aluminum foil/color steel phenolic composite air duct has environmental protection, lightweight quality, convenient installation, time-saving and labor-saving, and efficient insulation functions. Not only can it reduce energy consumption and pollution, but it can also ensure environmental cleanliness.
In contrast, colored steel phenolic air duct board has obvious advantages. Although double-sided aluminum foil air duct board has better insulation performance than iron sheet air duct, its strength and fire resistance are lower than iron sheet air duct. The outer layer of color steel phenolic air duct is color steel plate, and the inner insulation material is phenolic foam with the best incombustibility among organic materials. Therefore, it can avoid the defects of ordinary composite air duct and has obvious advantages. The outer layer of the colored steel phenolic air duct is treated with baking paint, which does not rust and is not easily damaged by external force collision. Therefore, the service life of the colored steel phenolic air duct will be significantly longer than that of ordinary composite air ducts.
