Flooring material heat radiation tester

Abstract

The invention discloses a flooring material heat radiation tester. The tester comprises a test rack, wherein a smoke exhaust fan, a heat source assembly, a workbench and a heat flow meter assembly are arranged on the test rack; the smoke exhaust fan is arranged at the top of the test rack, the heat source assembly cooperates with the workbench, and the heat flow meter assembly is arranged on the lower side of the workbench; the heat source assembly comprises a radiation heat source and a burner. According to the flooring material heat radiation tester, a certain radiation flux curve is obtained through calibration by the heat flow meter assembly, and the flame propagation distance is converted into the critical radiation flux value; according to the principle, the tester can predict the burning flame propagation capacity and the fireproof performance of materials; the tester can better simulate the burning behavior of the materials in a real fire environment, is applicable to quantitative tests of flame resistance of various materials and can be used by various material or product manufacturing institutions, research and development institutions, inspection departments, scientific research institutions and the like.

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...
