The phenolic composite air duct has good thermal insulation, which can greatly reduce the heat dissipation loss of the air conditioner, which reduces the equipment capacity of the central air conditioning system. It is also a very good tubular muffler, the muffler performance is very good, there is no need to set up muffler accessories such as muffler cover and muffler elbow. Therefore, the economic cost is greatly reduced, the weight is light, the building load can be reduced, and the installation is convenient, so the application scope is wide, and it is widely concerned by people.
The phenolic aluminum foil composite panel is a sandwich panel made of phenolic foam board and aluminum foil. The sandwich panel is combined with special flange accessories to make a phenolic composite air duct. Phenolic air ducts are generally used for central air-conditioning ventilation, which has a great improvement in comprehensive performance compared with ordinary traditional air ducts. The installation of phenolic air ducts is generally made, measured and installed on site after purchasing finished phenolic composite panels and accessories. The following are the construction process and precautions of phenolic air duct.
Using aluminum foil composite phenolic insulation board as the main material, using special production tools, according to the physical properties and chemical properties of the phenolic aluminum foil composite air duct, the aluminum-platinum composite phenolic insulation board can be cut, bonded and spliced conveniently and quickly at the construction site. The inner seam of the air duct is coated with sealant, and the ventilation duct is made, and then the air duct system is composed of special flanges and other parts and accessories. The length of the inner side of the phenolic duct is the dimension.
Main process flow and operation points
1. Construction process
Preparations → duct production → duct reinforcement → duct connection → duct hoisting → repair → detection.
2. Operating points
Preparation Before construction, prepare a set of special construction tools and make a work platform. Provide on-site technical disclosure and safety disclosure to construction personnel. Decompose the construction drawing of the air duct, determine the installation position of the air-conditioning equipment and the components of the air duct, disassemble the air duct system into straight air ducts, elbows, variable diameters, three-way, four-way, etc.; determine the straight air ducts and special-shaped Reasonable length and quantity of pipes; determine the connection method of air ducts and air-conditioning equipment and various components of air ducts and the corresponding connection accessories; determine the reinforcement method of air ducts; calculate the amount of plates; The auxiliary material ratio table calculates the amount of various auxiliary materials. Since the size of the phenolic foam sheet is 4000×1200mm and 2000×1200 (length×width), the specifications and sizes of the designed air ducts are various, so in the marking process, it should be accurately calculated, reasonably marked and cut material is the key to reducing material loss. Our VENTECH pre-insulated duct cutting machine is suitable for the fabrication of pre-insulated duct, PI duct, PIR duct, PU duct, phenolic foam duct, aluminum foil phenolic composite, etc. With a big working size 4000x1300mm, a phenolic foam board can be fully utilized. As a result, production efficiency has been greatly improved, material scrap has been reduced, and production costs have been saved for duct fabrication. And Our VENTECH software can automatic nesting several parts and different parts into duct sheet and automatic Set the cutting. No longer need to manually mark, create templates, or use Hand-held tool for cutting. It can maximize sheet usage and reduce material cost.
The production and installation process of phenolic aluminum foil composite air duct is advanced and rigorous, the air duct has good appearance, light weight, and is convenient for hoisting. On-site processing, molding, and one-time hoisting according to the design specifications and dimensions, without adding a thermal insulation layer. The phenolic aluminum foil composite air duct system has excellent fire resistance, excellent thermal insulation, anti-corrosion and anti-aging, good sound insulation, light weight and convenient construction, and has achieved obvious social and economic benefits. When the on-site installers design the air duct, they must pay attention to the accurate size and the reasonable use of materials to ensure that the material loss is not too large. VENTECH pre-insulated duct cutting machine may be the best choice to cut this kind of material.
