　　在現代建筑中，通風管的防火包裹受到人們的關注。之前常用的是鍍鋅鐵皮風管，但是無法耐火，所以很多人開始采用防火包裹的風管，有效提高了防排煙系統的防火耐火極限，保證了居民的建筑安全。那么，通風管防火包裹是怎么做的？

　　In modern architecture, the fireproof wrapping of ventilation ducts has attracted people's attention. Previously, galvanized iron sheet air ducts were commonly used, but they were not fire-resistant. Therefore, many people began to use fire-resistant wrapped air ducts, effectively improving the fire resistance limit of the smoke exhaust system and ensuring the safety of residents' buildings. So, how is the fireproof package for ventilation pipes made?

　　通風管防火包裹具有不燃、質輕、強度高等特點，防火包裹適用于電力電纜的防火保護，也適用于制作耐火風管、防火吊頂、鋼結構防火包覆。中央空調系統中，如果通風管是不耐火的材料，容易燃燒或者遇高溫變形，在明火的環境下很有可能會發生火災，所以通風管有必要做防火包裹。

　　Ventilation duct fireproof wrapping has the characteristics of non flammability, light weight, and high strength. Fireproof wrapping is suitable for fire protection of power cables, as well as for making fire-resistant air ducts, fireproof ceilings, and steel structure fireproof wrapping. In the central air conditioning system, if the ventilation ducts are made of non fire-resistant materials, they are prone to combustion or deformation when exposed to high temperatures, and there is a high possibility of fire in an open flame environment. Therefore, it is necessary to wrap the ventilation ducts with fire-resistant materials.

　　通風管防火包裹的材料一般是玻璃棉、巖棉。玻璃棉是一種纖維結構材料，達到A級不燃的防火建材標準。巖棉是由玄武巖高溫融化制成，可耐高溫，防火隔熱性能好，滿足A級不燃的防火要求。相關的建筑防煙排煙系統技術標準是為了合理設計建筑防煙、排煙系統，保證施工質量，規范驗收和維護管理，這樣可以減少火災危害，保護人身和財產安全！

　　The materials for fireproof wrapping of ventilation ducts are generally glass wool and rock wool. Glass wool is a fiber structural material that meets the A-level non combustible fire-resistant building material standard. Rock wool is made by melting basalt at high temperatures, which can withstand high temperatures, has good fire and thermal insulation properties, and meets the requirements of Class A non combustible fire protection. The relevant technical standards for building smoke prevention and exhaust systems are aimed at the rational design of building smoke prevention and exhaust systems, ensuring construction quality, standardizing acceptance and maintenance management, which can reduce fire hazards and protect personal and property safety!

　　通風管做防火包裹時，如果采用外包包覆，防火板厚度在8-10mm之間，耐火1小時的防火板為8mm，耐火2小時的防火板為10mm。如果采用風管+巖棉+防火板，需要8-9mm的耐火風管板材進行包覆處理，中間再填充尤特森巖棉，這樣通風管的耐火性能可以提升至1-3小時。

　　When making fireproof wrapping for ventilation ducts, if external wrapping is used, the thickness of the fireproof board should be between 8-10mm. The fireproof board that can withstand fire for 1 hour is 8mm, and the fireproof board that can withstand fire for 2 hours is 10mm. If air ducts, rock wool, and fireproof boards are used, 8-9mm fire-resistant air duct boards need to be wrapped and filled with Utson rock wool in the middle. This can improve the fire resistance of the ventilation duct to 1-3 hours.
