在我国的通风空调工程中，通风管道材质基本上可分为两大类，即镀锌铁皮制作类和玻璃钢风管制作类。目前，在绝大多数工程中，均使用前者。镀锌铁皮制作主要是现场制作加工，易改动，寿命长，但在潮湿环境中，较易腐烂。玻璃钢风管则容易老化，且易损。但是，在这几年，经过对 Ventilation and air conditioning projects in our country, ventilation duct material can basically be divided into two categories, namely, galvanized sheet metal production and production of FRP duct. At present, in the vast majority of projects, the former is used. Galvanized sheet metal production is mainly the scene production and processing, easy to change, long life, but in the humid environment, more perishable. FRP duct is easy to aging, and vulnerable. However, in recent years, after the right
