Construction materials flammability test device

Abstract

The invention relates to a construction materials flammable testing device, specifically to a flammability indicator test device to detect building materials burning time, flame height and 45degree tilt burning status, which belongs to the building materials testing device technology field. The invention comprises a box with a door, the sample fixture structure installed in the box, and the burning structure, the burning structure including the burner and the burner rotating structure, and the sample fixture structure including the vertical bar structure, the horizontal bar structure, and a sample hanging structure. The invention avoids the flame tempering phenomenon of the burner and overcomes the in-equable problem of the combustion and ignition location, and the construction materials flammable testing device of the invention can achieve flame conditioning, flame height adjustment, flame color adjust, and the burner can flexibly rotate at 0degree-45degree angle, and automatic ignite.

Description

technical field [0001] The invention relates to a building material flammability test device, in particular to a test device capable of detecting flammability indicators such as building material burning time, flame height and 45° inclined burning condition, which belongs to the technical field of building material testing devices. Background technique [0002] In the past two decades, the production technology of building materials has developed rapidly, and the flammability of building materials has become increasingly important. However, the test instruments used to test the flammability of building materials have not kept up with the market demand. Experimental instruments are very scarce. Since the building material flammability testing standard requires that the flame gas nozzle is very small, for the material flammability test instruments in other fields, since the oxygen inlet is hundreds of times that of the gas nozzle, it is very easy to cause backfire, that is, th...

[0002] In the past two decades, the production technology of building materials has developed rapidly, and the flammability of building materials has become more and more important. However, the test instruments used to test the flammability of building materials have not kept up with the market demand. The test equipment is very scarce

Since the building material flammability testing standard requires that the flame gas nozzle is very small, for the material flammability test instruments in other fields, because the oxygen inlet is hundreds of times that of the gas nozzle, it is very easy to cause backfire, that is, the flame does not come from The combustion port comes out, so these test instruments cannot be applied to the flammability test in the field of building materials, and the flammability test instruments in other fields cannot perform the test of flammability indicators such as flame height and 45° inclined combustion conditions.
