Description

Technical Field

[0001] This utility model relates to the field of air duct technology, and in particular to a magnesium-based high-crystal color steel composite fire-resistant air duct. Background Technology

[0002] In existing technology, air ducts are pipeline systems used for air transport and distribution, exhausting smoke from rooms and ensuring a clean and fresh environment. There are two types: composite air ducts and inorganic air ducts. Based on cross-sectional shape, air ducts can be divided into circular, rectangular, and flat-oval ducts, among others. Based on material, air ducts can be divided into metal ducts, composite ducts, and polymer ducts, among others. Smoke generally carries a large amount of heat, and almost all objects have the property of thermal expansion and contraction. This causes air ducts to deform when heated. Existing air duct structures are relatively simple, with low strength and poor deformation capacity, making them prone to bursting and rendering them unusable. Furthermore, air ducts have relatively limited functions, lacking good fire resistance, heat resistance, and pressure resistance, resulting in a short service life. Utility Model Content
