Hanshang air duct

Ventilation ducts are metal or non-metallic pipes used in ventilation and air-conditioning projects in industrial and civil buildings. They are a type of municipal infrastructure used to circulate air and reduce the concentration of harmful gases. The plates, profiles and other main finished materials used in the production and installation of air ducts should comply with the current national standards for design and related products, and factory inspection certificates should be applied. The materials should be accepted according to the current relevant national standards when they enter the site.
As the application of central air conditioning systems for heating and cooling in modern urban buildings becomes more and more common, the amount of duct materials used in ventilation ducts is also increasing year by year. In summary, the selection of air duct materials can be roughly divided into three categories. The first two categories are traditional galvanized iron plates + insulation layers, the second category is inorganic glass ducts, and the third category is composite lightweight insulation that has emerged in recent years. Air ducts are divided into phenolic, polyurethane, polystyrene, glass fiber and other categories. Among them, phenolic products are the most popular in the market.
Introduction to phenolic foam materials
Phenolic resin is the earliest industrialized plastic product in the world, and phenolic foam plastic is a variety that has just been successfully developed in recent decades. Phenolic foam is known as the king of thermal insulation. It was early used in the insulation of missiles and rocket heads. It has become the fastest growing variety of plastics in some developed countries such as the United States, Britain, and Japan.
Phenolic foam materials have the following characteristics
Phenolic foam materials are composed of flame retardant resin, curing agent, and non-flammable fillers. There is no need to add any flame retardant fillers, and the flame retardant grade is flame retardant.
Phenolic foam has a small thermal conductivity and excellent thermal insulation properties.
The phenolic foam material has been cured and formed, and there is no obvious aging phenomenon after long-term exposure to sunlight.
Phenolic foam has excellent sound absorption properties. 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, entertainment boxes, etc. are places where fireproof, lightweight, thermal insulation, sound insulation, clean and moisture-proof materials are required.
