Background

The air duct is a duct system for conveying and distributing air. There are two kinds of composite air pipe and inorganic air pipe. They can be classified according to their sectional shapes and materials. The stainless steel air duct is made by coating sealing glue (such as neutral glass cement) on the seams such as seaming seam, rivet seam, flange flanging four corners, etc. Before the sealant is coated, dust and oil stains on the surface are removed. According to the cross section shape, the air pipe can be divided into a circular air pipe, a rectangular air pipe, an oblate air pipe and the like, wherein the circular air pipe has the smallest resistance but the largest height and size, and is complex to manufacture. So the application is mainly based on a rectangular air pipe. The air pipe can be divided into a metal air pipe, a composite air pipe and a polymer air pipe according to the material. Fireproof air pipe: the air duct is made of non-combustible and fireproof materials and can meet a certain fire resistance limit.

When the traditional air pipe is used, the fireproof performance of the traditional air pipe is poor, so that the practical performance of the air pipe is influenced, and the service life of the air pipe is influenced.
