Embodiment 1

[0026] Example 1: The test device for the anti-radiation heat penetration performance of the fabric is composed of three parts: a radiation heat source, a copper plate calorimeter and a data acquisition system.

[0027] Such as figure 2 and image 3 As shown, the radiant heat source is composed of two silicon carbide heating rod groups 1 and a resistor 2, and the silicon carbide heating rod group 1 generates heat radiation after being energized. Silicon carbide heating rod group 1 includes 6 silicon carbide heating rods, each group of three is connected in series, and the two groups are connected in parallel, and then connected in series with resistor 2, and then connected to a 220V power supply.

[0028] Such as Figure 4 As shown, the copper plate calorimeter is composed of a copper plate 3 , a copper-constantan thermocouple 4 and an assembly block 5 . Used to measure the backside temperature of fabric samples. The copper-constantan thermocouple 4 is welded at the cente...

Abstract

The invention discloses a test device for radiant heat resistance of fabrics, and belongs to the field of safety technology. The test device comprises a radiative heat source, a copperplate calorimeter and a data acquisition system, wherein the radiative heat source consists of two silicone carbide heating rod sets and a resistor; each silicone carbide heating rod set comprises a plurality of silicone carbide heating rods which generate thermal radiation after being electrified; in a circuit, the silicone carbide heating rod sets are formed by serially connecting the silicone carbide heating rods, and the two parallelly connected silicone carbide heating rod sets are connected in series with the resistor and then connected to a 220V power supply; a copper-constantan thermocouple is welded in the center of the internal surface of the arc of a copperplate and then connected to an acquisition card through a through hole at an assembling block; the copperplate is glued to the assembling block through a bonding agent; the data acquisition system consists of the acquisition card and a computer, wherein the acquisition card acquires a temperature signal of the copper-constantan thermocouple and then inputs the temperature signal into the computer for data processing and computation, and the like. The test device is used for testing the radiant heat resistance of the fabrics, has the characteristics of reasonable structure, accurate test and strong operability, and can meet the requirements of the radiant heat resistance tests for the fabrics.

Description

technical field [0001] The invention belongs to the technical field of safety, and in particular relates to a test device for the anti-radiation heat penetration performance of fabrics. Background technique [0002] If the radiant heat encountered by firefighters during fire extinguishing operations exceeds the tolerance of the normal physiological balance process of the human body, it will cause dangers ranging from minor injuries to death. The heat in the fire scene spreads to the outside world in three ways: conduction, convection and radiation, among which heat radiation is the most important factor causing damage. Therefore, the anti-radiation heat penetration performance of firefighters' protective clothing is the key technical index to determine the protective performance of firefighters' protective clothing. [0003] At present, foreign countries with advanced technology have designed and manufactured test devices for firefighters' protective clothing anti-radiation...
