The plates, profiles and other main finished materials used for the fabrication and installation of ventilation pipes shall comply with the provisions of the current national standards for design and related products, and the factory inspection certificate shall be applied. The materials shall be accepted according to the current relevant national standards when entering the site. Yiguantong Xiaobian reminds you to pay attention to the use of air ducts of different materials.

在這樣的前提下，工業通風系統選用的風管材質為鋼板和鍍鋅板。凈化空調系統選用的風管材質為鍍鋅板和不銹鋼，不要用可能出現塵源污染的玻璃鋼、復合材料的風管;環境控制系統選用的風管材質為鍍鋅板和不銹鋼。

On this premise, the air duct materials selected for the industrial ventilation system are steel plate and galvanized sheet. The air duct selected for the purification and air conditioning system is made of galvanized sheet and stainless steel. Do not use FRP and composite air ducts that may be polluted by dust sources; The air duct selected for the environmental control system is made of galvanized sheet and stainless steel.

空調系統用的是鍍鋅板和彩鋼保溫板風管。在特殊場合，例如礦產商用涂膠布風筒和礦用塑料通風管，這樣可以阻燃抗靜電礦用的特性。此外還有玻璃鋼風管分有*和無機二種，有消防要求的是禁用材質的。

The air conditioning system uses galvanized sheet and color steel insulation board air duct. In special occasions, such as mineral commercial coated cloth air duct and mining plastic ventilation pipe, this can improve the characteristics of flame retardant and antistatic mining. In addition, there are FRP air ducts, which are divided into * and inorganic. The materials with fire protection requirements are prohibited.

目前，非金屬風管材料發展較快，品種較多，困其具有的特性和優點，應用也越來越廣泛。為了保證使用中的，對這些材料制作的風管提出了應按工程的需要具有不燃或難燃B1級的燃燒性能要求，而其表面層為不燃材料。

At present, non-metallic air duct materials develop rapidly and have many varieties. Due to their characteristics and advantages, they are more and more widely used. In order to ensure the in use, the air ducts made of these materials are required to have the combustion performance of incombustible or flame retardant grade B1 according to the needs of the project, and the surface layer is made of incombustible materials.
