Description

Technical Field

[0001] The utility model relates to the technical field of galvanized steel plate air ducts, in particular to a heat-insulating and fire-proof galvanized air duct. Background Art

[0002] Ducts are pipe systems used for air delivery and distribution. There are two types: composite ducts and inorganic ducts. Durkduct ducts are the representative of composite ducts. Ducts can be classified according to cross-sectional shape and material. Duct production Stainless steel duct production is to apply sealant (such as neutral glass glue) to the seams such as the bite seams, rivet seams, and the four corners of the flange. The surface dust and oil should be removed before applying the sealant. According to the cross-sectional shape, ducts can be divided into circular ducts, rectangular ducts, oblate ducts, etc. Among them, circular ducts have the smallest resistance but the largest height size and are complex to make. Therefore, rectangular ducts are mainly used. According to the material, ducts can be divided into metal ducts, composite ducts, and polymer ducts. Galvanized steel plates are welded steel plates with hot-dip or electroplated zinc layers on the surface. They are generally widely used in construction, home appliances, vehicles and ships, container manufacturing, electromechanical industry, etc.

[0003] However, when installing the existing ones on the market, there is no fixed place to lift the air duct, and most of them are directly lifted, which may damage the air duct. At the same time, the current air duct insulation and fireproof capabilities are relatively general, which will reduce the service life of the air duct. Therefore, it is necessary to design thermal insulation and fireproof galvanized air ducts. Utility Model Content
