Abstract

The present invention relates to a non-metallic material combustion performance testing apparatus, which comprises a combustion box body, a flaming device, a sample fixing device and a combustion gas control mechanism. The flaming device and the sample fixing device are connected with the internal bottom plate of the combustion box body. The combustion gas control mechanism comprises a gas flow and pressure control part, and a gas switch and timing control part. The flaming device is connected with the pipeline of the gas flow and pressure control part and is electrically connected with the gas switch and timing control part. The flaming device comprises a sliding block, a guide rail, a 45-degree bracket, a Bunsen burner installation plate, a Bunsen burner base, a Bunsen burner lamp tube and a Bunsen burner nozzle. The guide rail is fixedly mounted onto the internal bottom plate of the combustion box body and is connected with the internal bottom plate. The sliding block is in sliding fit with the guide rail and is connected with the guide rail. One side surface of the sliding block is provided with a push-pull rod. Based on the above structure, the included angle and the distance of a flame nozzle relative to a test sample can be conveniently adjusted. Meanwhile, the test cost is lowered, and the operation flow is facilitated.

Description

technical field [0001] The invention relates to a non-metallic material combustion performance test, in particular to a non-metallic material combustion performance test device. Background technique [0002] The non-metallic material combustion performance test device is generally in accordance with the requirements of domestic and foreign standards. The gas flame directly impacts the test sample at a certain angle, time and position to observe the self-ignition time, combustion size, and combustion phenomenon of the sample after ignition. A test for judging the flame retardancy of a material. [0003] In the general combustion performance test, since the angle and distance between the flame nozzle and the sample sample are specified in the standard for each material, the difference in the sample material, the corresponding test flame nozzle and sample sample The included angles and distances are also different, so in the prior art, it is necessary to prepare a variety of ...
