Problems solved by technology

[0003] The flame retardant test of textile materials can neither simulate the battlefield burning environment, reproduce the burn process of the human body in the burning state of clothing, nor reflect the protective effect of clothing with different structures on the human body, let alone reflect the damage degree of different fire sources to the human body-clothing system , has brought great blindness to the research of flame-retardant clothing, and restricted the development of flame-retardant protective clothing

Abstract

The invention relates to a dummy man burning system, which includes a dummy man body, density of heat flow rate of skin, a temperature detector, a signal collector and a single chip micro-processor, a remote communication interface, a computer, the invention is characterized in that: the dummy man body whose thermal coefficient is similar to the thermal coefficient of the dummy man skin is made of nonmetal material; the surface of the dummy man is processed by high-temperature flame-retardant, and is set a plurality of sensors of the density of heat flow rate and temperature; the signal collector and the single chip micro-processor are consist of a plurality of data collection sets and process units, and transmit the density of heat flow rate and the temperature to a computer control terminal through a data bus. The dummy man system can simulate a thermal reaction of the dummy man skin in fire scene, and is used for determining and estimating a flame-retardant insulation property of clothes.

Description

technical field [0001] The invention relates to a combustion dummy system, which is a test system capable of simulating the thermal response of a human body to a fire scene, and is used for measuring and evaluating the heat-insulation and flame-retardant performance of clothing or equipment, belonging to the field of clothing ergonomics and personal protection. Background technique [0002] At present, the evaluation of the flame retardant performance of flame retardant protective clothing in my country has always been based on the vertical combustion test of small sample textile materials and subjective judgment. This is only a material selection experiment, the method is simple, and the means are limited. The fire performance of protective clothing depends on many factors, such as fiber material, fabric structure, clothing design, clothing matching and so on. [0003] The flame retardant test of textile materials can neither simulate the battlefield burning environment, re...
