[0002] Energy-saving building materials are commonly used materials in house decoration or other interior decoration projects. Their fire resistance is extremely important. The fire resistance test of building materials is simply to use a flamethrower to spray fire on the surface of the building material board, observe the degree of flame burning and the speed of flame spread, and then know the quality of the fire resistance of the board. When testing it, a test device is needed to test it.
[0003] Currently, when conducting fire resistance tests on building materials, a flamethrower is generally used to spray fire on the building materials, and a glass cover is used to cover it to prevent it from producing irritating odors that affect the workers. However, some building materials will produce black smoke when exposed to flames. The black smoke easily adheres to the glass cover and is difficult to clean. Utility Model Content

[0013] Compared with the existing technology, the present invention provides a fire performance testing device for energy-saving building materials, which has the following beneficial effects:
[0014] 1. This energy-saving building material fire performance testing device uses a flamethrower to heat the building materials and conduct fire tests on them. Black smoke is generated by some building materials, and the air is extracted by a vacuum pump. At this time, the gas in the glass cover passes through the arc tube, fixed tube, exhaust pipe, filter box and connecting pipe in sequence, and is finally discharged by the vacuum pump.

[0015] 2. This energy-saving building material fire performance testing device turns on the heating wire through the controller. When the outside gas enters the glass cover, it first enters the sealing ring through the through groove, and then enters the glass cover through the air inlet after being heated by the heating wire, thereby effectively preventing the incoming gas from causing the building material to cool down and affecting its fire test efficiency.
[0016] The parts not involved in this device are the same as the existing technology or can be implemented by using the existing technology. The utility model effectively prevents the black smoke generated by the combustion of some building materials from adhering to the glass cover, and filters the extracted gas through the filter box, effectively preventing the gas generated by the test from polluting the air, and effectively preventing the incoming gas from causing the building materials to cool down and affecting the efficiency of its fire protection test.
