Abstract

The utility model discloses a fabric horizontal combustion text box which is characterized in that a horizontal workbench is arranged below the box body; a circular hole is formed in the center of the workbench; an igniter is arranged right under the circular hole; a guide pipe is arranged on the igniter; the guide pipe penetrates out of the box body and is provided with an ignition switch; a ventilating port is arranged below the vertical face of the box body; a smoke discharging port is arranged at the top of the box body; a fire extinguishment sprayer is arranged above the workbench and is connected to a fire extinguisher outside the box body through the guide pipe; a door is arranged on one vertical face of the box body; and a glass observation window is formed in the other vertical face of the box body. The test equipment has the beneficial effects that 1) a horizontal fabric combustion test environment meeting an actual condition is simulated, and 2) the degree and the direction of fabric damage spreading of a fabric during horizontal combustion are comprehensively reflected.

Description

Fabric horizontal burning test case

Technical field

The utility model is about the fabric corrosion chamber, especially a kind of test unit of test fabric horizontal firing performance.

Technical background

At present, the combustion testing mode of common fabric mainly is that fabric is cut cloth into certain-length along warp-wise or broadwise, then it is placed at 45 or 90 ° with surface level, igniting below cloth again, cause the time of certain position by the burning of test cloth, or the burning length in the certain hour, characterize the burning performance of this fabric.These class methods are simple and the result stable, extensively used.But also have certain defective, at first, in actual use, as carpet, tablecloth etc., there is difference in the fabric that has a large amount of level to lay with combustion system and its environment in actual applications of 45 ° or 90 °; Secondly, these class methods can only reflect that fabric is at the burning length of warp-wise or broadwise, and in fact the burning of fabric to spread be the coefficient result of warp-wise and weft fiber, lose biasedly if only characterize with the result of warp-wise or broadwise, and can not reflect the directivity that Actual combustion spreads and damage area.

The utility model content

The utility model overcomes the deficiencies in the prior art, proposes a kind of test unit that more meets horizontal fabric burning reality and concentrated expression fabric burning damage feature.

The utility model is achieved by the following technical solutions:

Below the casing of burning test case horizontal table is installed, there is a circular hole in worktable central authorities, and lighter is installed under the circular hole, and conduit is arranged on the lighter, and conduit passes outside the casing, and ignition switch is installed; There is ventilating opening casing facade below; Box top has exhaust opening; The worktable top is equipped with fire extinguishing sprayer, and fire extinguishing sprayer is connected to the outer flame snuffer of casing by conduit; On casing one facade door is arranged, on another facade of casing glass window is arranged.

Adopt the beneficial effect of above technical scheme to be 1) simulated the test environment of the horizontal fabric burning of realistic condition; 2) fabric of concentrated expression fabric in horizontal firing damaged degree and the direction that spreads.

Description of drawings

Fig. 1 structural representation of the present utility model.

Among the figure: 12 glass window of casing, 3 lighters, 4 lighter conduits, 5 ignition switch, 6 fire extinguishing sprayers, 7 flame snuffers, 8 ventilating openings, 9 exhaust openings, 10 fire extinguishing sprayer conduits, 11 horizontal tables 412

Embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described further:

As accompanying drawing 1, below the casing 1 of burning test case, horizontal table 12 is installed, there is a circular hole in worktable central authorities, and lighter 4 is installed under the circular hole, and lighter conduit 5 is arranged on the lighter, and conduit passes outside the casing, and ignition switch 6 is installed; There is ventilating opening 9 casing facade top; Box top has exhaust opening 10; The worktable top is equipped with fire extinguishing sprayer 7, and fire extinguishing sprayer is connected to the outer flame snuffer 8 of casing by fire extinguishing sprayer conduit 11; Door 2 is arranged on casing one facade, on another facade of casing glass window 3 is arranged.
