Knowledge Base

Q

The fireproof wrapping technology of smoke exhaust ducts is mainly applied in the fire protection system of buildings, especially in situations where a large amount of smoke needs to be eliminated and air circulation needs to be maintained. Through this technology, the spread of fire can be effectively delayed, ensuring the safety of personnel evacuation. This article will provide a detailed interpretation of the specific applications of this technology. Fireproof wrapping technology for smoke exhaust ducts in modern buildings

Q

The centrifugal glass wool fireproof wrapping construction plan - Baidu Love Procurement has launched the "Technical Standard for Building Smoke Control and Exhaust System" GB51251-2017, which puts forward the requirement of fire resistance limit for all smoke control and exhaust ducts. However, traditional iron sheet ducts cannot meet the requirement of fire resistance limit. Therefore, more and more places are paying attention to the insulation measures of ducts. Today, the editor will give a brief introduction

Q

1、 Functional Characteristics Analysis 1. Core fire resistance performance High temperature resistance: The high temperature resistance limit of aluminum silicate fiber can reach 1000-1700, which can maintain structural stability and delay heat transfer in high temperature environments during fire. Thermal insulation: The porous structure inside the fiber forms an air insulation layer, which can effectively reduce the heat conduction rate and minimize the impact on the protected object
