In modern buildings, central air conditioning has become very common, and ventilation ducts are an important part of the central air conditioning system. According to statistics, the annual demand in my country is about 100 million square meters, reaching 20 billion yuan. Among all kinds of air ducts, the modified phenolic foam aluminum foil composite air duct stands out with its unique excellent performance and cost performance and is becoming the new favorite in the central air-conditioning market.
The modified phenolic foam aluminum foil composite thermal insulation air duct is processed by the modified phenolic foam aluminum foil composite sandwich panel, and the quality of the board directly affects the quality of the air duct. At present, the advanced continuous method is generally used to produce phenolic foam aluminum foil composite sandwich panels, with high production efficiency and stable and reliable quality.
The reason why the modified phenolic foam aluminum foil composite air duct has become the darling of the market is that it has obvious technical, energy saving, environmental protection, and economic advantages compared with the air duct of traditional materials. Such products have been tested and proved by relevant authoritative institutions such as the National Building Materials Testing Center, the National Fireproof Building Materials Quality Supervision and Inspection Center, the National Air-conditioning Equipment Quality Supervision and Inspection Center, and the National Nonferrous Metals Quality Supervision and Inspection Center. Flame retardant performance, the oxygen index is as high as 40% or more, which is twice that of the oxygen in the air, and no smoke is produced in the fire, and the smoke density is only 4, which is one-tenth to one-twentieth of other organic foam materials. The smoke toxicity index test according to the British NES713 standard shows that the toxicity index per 100 grams of sample is less than 5, which is a safe product. Its thermal conductivity varies with the density of about 0.03w/m·k, and it does not shrink or deform at ±150 °C. It has excellent thermal insulation performance and is an excellent representative of thermal insulation and energy-saving materials. According to GB50045-95 "Code for Design and Fire Protection of High-rise Civil Buildings", the definition of the non-combustible body, non-combustible body, and combustion body and the principles stipulated in GB8624-1997 "Classification method of combustion performance of building materials", modified phenolic foam aluminum foil composite insulation The combustion performance of the air duct is higher than that of the refractory body, and it is close to the non-combustible body. This quality of it is very valuable. The modified phenolic foam aluminum foil composite air duct has a special process for the front and back sides of the aluminum foil. After testing, it has good performance on phosphoric acid, nitric acid, sulfuric acid, hydrochloric acid, peracetic acid, sodium hydroxide, sodium chloride, and other substances. Corrosion resistance, thus greatly extending the service life and making it economical.
In addition, the modified phenolic foam aluminum foil composite air duct also has the advantages of low friction resistance, noise reduction and sound insulation, lightweight, which can reduce the construction load, easy to process and manufacture, easy to install, and short construction period, elegant and beautiful appearance, clean and hygienic. Features such as lower cost. It can be said that the modified phenolic foam aluminum foil composite air duct combines the advantages of various traditional air ducts. It meets the requirements of human society for energy saving, environmental protection, health and harmonious development. Engineering designers, construction and installation personnel, and new favorites of the market are inevitable.
