A thermal radiation tester for paving materials

Abstract

The invention discloses a thermal radiation tester for flooring materials, which comprises a test frame, on which a smoke exhaust fan, a heat source assembly, a workbench and a heat flow meter assembly are arranged; the smoke exhaust fan is arranged on the test frame At the top, the heat source assembly is matched with the workbench, and the heat flow meter assembly is arranged on the lower side of the workbench; the heat source assembly includes a radiation heat source and a burner; the thermal radiation tester for flooring materials of the present invention is determined by calibration of the heat flow meter assembly Based on the radiant flux curve, the distance of flame propagation is converted into its critical radiant flux value; based on this principle, the flame propagation ability and fire performance of materials can be predicted; and it can better simulate the behavior of materials in real fire environments Combustion behavior, suitable for quantitative testing of flame retardant properties of various materials, can be used by various material or product manufacturing units, research and development units, inspection departments and scientific research units.

Description

technical field [0001] The invention relates to a thermal radiation tester for flooring materials, in particular to a thermal radiation tester for flooring materials that measures critical radiation flux values ​​of materials based on a radiant heat source method and predicts the combustion performance and flame propagation ability of flooring materials. Background technique [0002] With the development of society, the increase of material wealth and population density, the frequency of fires and the resulting harm are also increasing, and the use of flame-retardant materials is one of the strategic measures to reduce and prevent fires; nearly 30 In recent years, countries have paid more and more attention to the process of flame retardancy of materials; because the combustion behavior of flame retardant materials in a fire is very complex, a single combustion test method cannot fully describe its combustion performance, so people try to Research on the testing and characte...

[0002] With the development of society, the increase of material wealth and population density, the frequency of fires and the resulting damage are also increasing, and the use of flame-retardant materials is one of the strategic measures to reduce and prevent fires; nearly 30 In recent years, countries have paid more and more attention to the process of flame retardancy of materials; because the combustion behavior of flame retardant materials in a fire is very complex, a single combustion test method cannot fully describe its combustion performance, so people try to Research on the testing and characterization methods of flame retardant materials, and evaluate the flame retardant performance of flame retardant materials more completely from many aspects
