Chengdu phenolic composite air duct board wholesale construction process, single-sided color steel phenolic composite air duct combines the double advantages of traditional materials and modern technology, which not only enhances the insulation performance of the board, but also improves the external strength and fire resistance. It is also waterproof, tasteless, non-toxic, non-corrosive, non crack, non deformation, non combustion, high strength and light weight, convenient construction, long service life and other characteristics. Based on the author's construction experience for many years, this paper points out the process and method of making setting out, cutting, forming, strengthening, connecting and hoisting of single-sided color steel phenolic composite air duct. Chengdu phenolic composite air duct board wholesale uses single-sided color steel phenolic composite air duct, outer surface steel plate, inner surface aluminum foil.

The thickness of the color steel plate is not less than 0.3mm, the thickness of the aluminum foil is not less than 70 m, the aluminum foil needs to have an anticorrosive coating, the thickness of the phenolic plate is not less than 20mm, the thickness difference of the sheet is less than or equal to 0.7mm, the density of phenolic foam is larger than or equal to 65kg/m3, the adhesive of phenolic foam and aluminum foil can not be used as adhesive, the combustion property is required to be non combustible grade A, and the fire-resistant time is not less than 60min, which needs continuous foaming. The foaming agent adopts non flammable and explosive environmental protection substances. Chengdu phenolic composite air duct board wholesale adopts flange connection, which requires the use of cold break bridge flange. The flange material requires aluminum alloy. The flange and phenolic plate interface sealant need to use heat-resistant and corrosion-resistant environmental protection products. After installation, environmental protection centrifugal glass wool board is used to insulate the flange parts.

The production, processing, strengthening and installation requirements of phenolic composite air pipes are required according to the requirements of "aluminum foil rigid phenolic foam sandwich panels", "ventilation pipe technical specification", "non-metallic wind pipe production and installation process standard", "ventilation pipe fire test method" and "classification of building materials and products combustion performance". The manufacturing enterprises must pass ISO series certification.
