Description
Technical Field
The invention relates to the technical field of building material testing, in particular to a device for detecting the combustion performance of a thermal insulation material in building engineering.
Background
The national standard GB8624-97 of China classifies the combustion performance of building materials into the following grades. A level: incombustible building material: a material that burns little. Level B1: flame-retardant building materials: the flame-retardant material has better flame-retardant effect. It is difficult to ignite in the air when meeting open fire or under the action of high temperature, is not easy to spread quickly, and can be immediately stopped after the fire source is removed. Level B2: combustible building materials: the combustible material has a certain flame-retardant effect. Need carry out the measuring of combustion behavior after the insulation material is produced, prior art CN109115936A discloses a building engineering insulation material combustion behavior check out test set, the crooked degree when pressing from both sides and can burning insulation material through the counter weight enlargies, the resistance to compression attribute after the burning of insulation material can further be known to the crooked degree, make test link more comprehensive, can be with the inside smoke and dust automatic discharge of shell through fume extractor, reduce the inside temperature of shell and smog concentration, guarantee equipment can normally work, the stability of equipment has been improved. However, the device has the disadvantages that the smoke generated by the device after the heat-insulating material is burnt is only 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. Due to the diffusion of gas, tiny floating dust in suspended particles can enter the lung of a human body and is accumulated on the alveolar wall, the gas can be spread to the whole body along with blood to cause respiratory system diseases, the device is inconvenient to filter smoke generated during combustion, harmful smoke can cause damage to the human body, and meanwhile, the fixing frame in the device is fixed in position and is inconvenient to adjust, so that the detection mode is single and more detection data are inconvenient to provide during detection;
in addition, the existing heat insulation materials aiming at different shapes involve ignition of materials in the combustion performance detection process, sufficient combustion is achieved, smoke dust is sucked in the combustion process, the carbonized part is knocked, and the length of the remaining part, which is not completely carbonized, of the materials after sintering is burned is measured, so that knocking and ignition equipment, collecting equipment for completely carbonized solid garbage and gas recovery equipment for smoke dust are required to be simultaneously arranged in an existing combustion experiment box, the complexity of the whole device is high, the occupied space of the equipment in a combustion chamber is large, and in addition, ignition operation at multiple positions is required sometimes to be carried out in a material combustion ignition area to carry out rapid ignition, for example, the materials capable of being combusted are determined.
In view of this, we propose a building engineering insulation material combustion performance check out test set.
