Abstract

The invention relates to a device for testing the open fire prevention and heat insulation performance of fabric, which comprises a thermal cavity, a specimen holder, a fire scene generation device, a gas source, a temperature measurement device and a data acquisition processing unit. The device generates a high-temperature high-heat flow open fire scene environment by the gas source and the fire scene generation device; a fabric specimen is placed in the environment; the temperatures of the front and back of the fabric specimen change under the function of high temperature and high heat; the temperature measurement device online measures the change of the temperatures of the front and back of the fabric specimen with exposure time in real time; and the data acquisition processing unit records the curve of the temperature change with the time in real time so as to analyze and represent the open fire prevention and heat insulation performance and temperature isolation behavior of the fabric. The device has the characteristics of high testing efficiency, stable and reliable working performance, operation repeatability, simple operation, wide application range and the like, and can be used for the test and inspection of the long-term thermal protection performance and temperature isolation behavior of the fabric in the open fire scene environment.

Description

technical field [0001] The invention relates to the technical field of fire safety testing, in particular to a testing device for fabric anti-open flame thermal insulation performance and temperature insulation behavior. Background technique [0002] The current test methods for testing the fire and heat insulation performance of fabrics mainly use the test methods for the combustion performance of fabrics and various test methods for the thermal protection performance of fabrics. Fabric combustion performance testing methods, including vertical method (GB5455-1997), horizontal method, oxygen index method (GB / T 5454-1997), 45° tilt method and smoke concentration method, etc. The obtained indicators can only express the flame retardancy of the fabric , cannot express the thermal resistance of fabrics to high temperature and high heat and the protection ability of human skin in high temperature and strong heat flow fire environment, so it can only be used to test the flammabil...
