B1 stage: flame-retardant building material: the flame-retardant material has better flame-retardant effect. The fire-extinguishing agent is difficult to fire in the air or under the action of high temperature, is not easy to spread quickly, and burns immediately after the fire source is removed. B2 stage: combustible building material: the combustible material has a certain flame-retardant effect. The utility model discloses a need carry out combustion performance's detection after thermal insulation material produces, prior art CN109115936A discloses a building engineering thermal insulation material combustion performance check out test set, can enlarge the crooked degree when thermal insulation material burns through counter weight clamp and balancing weight, can further know thermal insulation material's compression resistance after the burning through crooked degree for test link is more comprehensive, can be with the inside smoke and dust automatic discharge of shell through fume extractor, reduces the inside temperature of shell and smog concentration, and guarantee equipment can normally work, has improved the stability of equipment. However, the device has the defect that smoke generated after the heat insulation material is combusted is simply discharged through the smoke discharging device, and suspended particles in the smoke are harmful because the smoke contains a large amount of toxic gas. Because of the diffusion of gases, tiny floating dust in suspended particles can enter the lung of a human body and accumulate on alveolus walls, the gases can be transmitted to the whole body along with blood to cause respiratory diseases, and the device is inconvenient to filter smoke generated during combustion, so that harmful smoke can damage the human body, and meanwhile, the fixing frame in the device is fixed in position, so that the device is inconvenient to adjust, the detection mode is single during detection, and more detection data cannot be provided conveniently.
In addition, the existing thermal insulation materials with different shapes relate to ignition of materials in the combustion performance detection process, the materials are fully combusted, smoke dust in the combustion process is sucked, the carbonization part is knocked, and the length of the residual incomplete carbonization part of the materials after the combustion is finished is measured, so that the existing combustion experiment box is also required to be simultaneously provided with knocking and ignition equipment, and collection equipment of the complete carbonization solid garbage and gas recovery equipment of the smoke dust, the complexity of the whole device is higher, the occupied space of the equipment in the combustion chamber is larger, and in addition, the ignition operation at a plurality of positions is sometimes required in the material combustion ignition area so as to perform rapid ignition, for example, the ignition of materials capable of being combusted is determined.
In view of the above, we propose a combustion performance detection device for a thermal insulation material of a building engineering.
