Galvanized air duct, a good ventilation duct, is very well used in industry. The seller said that galvanized air duct also has good fire resistance, but we don't know what aspects this is mainly reflected in. Today, Xiaobian will tell you in detail.
The galvanized air duct shall be protected from damage during transportation. The galvanized air duct end of FRP composite plate is an open profile. Before assembling the flange connector, it should be sealed with tape or glue to prevent the glass fiber from being exposed or scattered.
Galvanized air duct has good processing performance and good sealing performance. Many customers choose galvanized air duct because of its high economic efficiency. Galvanized air duct saves materials in the production process. Galvanized air duct not only saves labor and materials in manufacturing, but also has lower cost because its quality is lighter than other air ducts in operation.
It is learned that the protective and decorative performance of galvanized air duct can be significantly improved after passivation, dyeing or coating with color protection agent. In addition, the fire protection performance of galvanized air duct is first reflected in that it is incombustible. However, it needs to be noted that whether its insulation layer burns depends on the material.
Through this paper, we can know that the fire resistance of galvanized air duct can be reflected in many aspects. Similarly, when using galvanized air duct, there is no good silencing function, so we need to add muffler to the air duct, and its thermal conductivity is high, so there is no thermal insulation function. Therefore, we need to add another thermal insulation layer when using it, and there are requirements for the application environment, It can not be applied to some humid environments, so it is often easy for the galvanized air duct to be affected by the environment and prone to corrosion, all of which need to be paid attention to.
