山东通风管道:通风管防火包裹怎么做?
来源:http://www.jntfgd.com 日期:2024-08-28 发布人:创始人
在现代建筑中,通风管的防火包裹受到人们的关注。之前常用的是镀锌铁皮风管,但是无法耐火,所以很多人开始采用防火包裹的风管,有效提高了防排烟系统的防火耐火极限,保证了居民的建筑。那么,通风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?
通风管防火包裹具有不燃、质轻、强度高等特点,防火包裹适用于电力电缆的防火保护,也适用于制作耐火风管、防火吊顶、钢结构防火包覆。空调系统中,如果通风管是不耐火的材料,容易燃烧或者遇高温变形,在明火的环境下很有可能会发生火灾,所以通风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.
通风管防火包裹的材料一般是玻璃棉、岩棉。玻璃棉是一种纤维结构材料,达到A级不燃的防火建材标准。岩棉是由玄武岩高温融化制成,可耐高温,防火隔热性能好,满足A级不燃的防火要求。相关的建筑防烟排烟系统技术标准是为了合理设计建筑防烟、排烟系统,保证施工质量,规范验收和维护管理,这样可以减少火灾危害,保护人身和财产!
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!
通风管做防火包裹时,如果采用外包包覆,防火板厚度在8-10mm之间,耐火1小时的防火板为8mm,耐火2小时的防火板为10mm。如果采用风管+岩棉+防火板,需要8-9mm的耐火风管板材进行包覆处理,中间再填充尤特森岩棉,这样通风管的耐火性能可以提升1-3小时。
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.
