Dacote phenolic composite air duct
The middle layer is phenolic foam. The inner and outer layers are composed of embossed aluminum foil.
Phenolic resin is the earliest industrialized plastic product in the world, while phenolic foam is a variety that has just been successfully developed in recent decades. Phenolic foam is known as the king of thermal insulation and was used in early rocket insulation. Phenolic foam materials have good flame retardant properties, small thermal conductivity, excellent sound absorption properties and long service life. Due to the above superior properties, phenolic foam materials have been widely used in various aspects of the national economy, such as central air-conditioning ducts, hot and cold transportation ducts, clean workshops, shopping malls, light-body quick-loading rooms, cold storage, refrigerated trucks, aircraft, Ships, hotels and private rooms are places where fireproof, lightweight, thermal insulation, sound insulation, clean and moisture-proof materials are required.
Phenolic foam board and aluminum foil are combined to form a sandwich panel, and then special flange accessories are added to form a phenolic composite air duct for central air conditioning ventilation. The inner and outer surfaces of the phenolic composite sandwich panel are coated aluminum foil, and the middle layer is made of phenolic foam material. Its comprehensive performance has been greatly improved, especially in terms of mechanical properties, such as bending resistance, compression resistance, brittleness and processing performance. There have been major improvements, which basically meet the requirements for the use of air conditioning ventilation ducts.

, and has good thermal insulation performance. The Zhongrui composite air duct system uses high-strength high-quality plates with a thermal conductivity lower than. Standard accessories, supplemented by professional tools and excellent construction technology, the air leakage is less than ./㎡(), the maximum energy saving is more than %, leading the industry, and can greatly reduce the heat loss of air conditioners
, light weight and high strength. In particular, the outer surface of the air duct is very hard and impact-resistant
, easy to install, and has a short production cycle
. The air duct insulation is integrated, and there is no need to reserve a floor height space. After the on-site production is completed, it can be lifted directly to the surface. Installation on the first floor can reduce the floor height requirements of the building, greatly saving construction costs, and at the same time saving ceiling space
. It has excellent sound insulation and noise reduction functions
and is green and environmentally friendly. All material-level accessories are The use of non-toxic and odorless green environmentally friendly products ensures fresh air, comfortable and pleasant Dacote double-sided aluminum foil phenolic composite air duct
As the application of central air conditioning systems for heating and cooling in modern urban buildings becomes more and more common, the air in ventilation ducts The amount of pipe materials used is also increasing year by year. Generally speaking, the selection of air duct materials can be roughly divided into three major categories. One is the traditional galvanized iron plate with an insulation layer, the other is the inorganic glass duct, and the third category is the composite lightweight insulated air duct that has emerged in recent years. This type of products is further divided into phenolic, polyurethane, polystyrene, extruded polystyrene, glass fiber, foam rubber and other categories. Among them, phenolic foam products are the most popular in the market. Phenolic foam insulation material is a polymer organic rigid aluminum foil foam product, which is foamed from thermosetting phenolic resin. It is lightweight, fireproof, does not burn when exposed to open flames, smokeless, non-toxic, non-dripling, and can be used in a wide temperature range (~+℃). It does not shrink or become brittle in low temperature environments, making it an ideal thermal insulation material for HVAC and refrigeration projects. Due to its high closed cell ratio, phenolic foam has low thermal conductivity, good thermal insulation performance, water resistance and water vapor permeability, making it an ideal thermal insulation and energy-saving material. Since phenolic has a benzene ring structure, it is dimensionally stable and has a change rate of less than %. It has stable chemical composition, anti-corrosion and anti-aging, and is especially resistant to corrosion by organic solutions, strong acids and weak alkali. Freon is not used as a foaming agent in the production process to comply with international environmental protection standards, and its molecular structure contains hydrogen, oxygen, and carbon elements. When decomposed at high temperature, the gas that escapes is non-toxic, odorless, and harmless to the human body and the environment. Comply with national green environmental protection requirements. Therefore, phenolic super composite board is the most ideal environmentally friendly green insulation material with fire protection, heat insulation, energy saving and beauty. Phenolic foam is known as the king of thermal insulation materials and is a new generation of thermal insulation, fireproof and sound insulation materials. At present, phenolic foam materials are developing rapidly in developed countries and have been widely used in construction, national defense, foreign trade, storage, energy and other fields. Phenolic materials account for % of the sound insulation and thermal insulation foam used in the U.S. construction industry. Japan has established a phenolic foam popularization association to promote this new material.
Dakote double-sided aluminum foil phenolic composite air duct product description
