本项目内衬风管采用玻璃纤维弹性绝缘,带有认可的耐火涂层来防腐,粘有黑色热固性树脂。其区别于普通风管的主要是防腐隔热层在管道内部,在保证风管隔热的效果的同时,又能起到消音的效果。且内保温还能减少通过金属管道壁发生的热量获得和热量丢失,帮助避免管道内壁和管道外壁冷凝现象的产生。管道内衬与金属风管必须一同生产加工,形成内衬风管成品,这点也区别于现场加工的普通风管。
The project lined air duct is made of fiberglass elastic insulation, with approved refractory coating to prevent corrosion, stuck with black thermosetting resin. It is different from the ordinary duct is mainly anti-corrosion insulation layer inside the pipe, duct insulation to ensure the effect, but also play a silent effect. And the internal insulation can also reduce the heat gain and heat loss through the metal pipe wall, helping to avoid the condensation of the inner wall of the pipe and the outer wall of the pipe. Pipeline lined with metal duct must be together with the production process, the formation of lined duct products, which is also different from the site of ordinary duct processing.
