Problems solved by technology

[0008] Therefore, the use of small molecule combustible gases to evaluate the explosion performance of barrier explosion-proof materials to liquid fuel saturated vapor cannot reflect the real situation.
If it is considered that small molecule combustible gas is more "explosive" than liquid fuel saturated vapor, and if it can prevent the explosion of small molecule combustible gas, it will certainly be able to prevent the explosion of liquid fuel saturated vapor, as a judgment for evaluating the use of barrier explosion-proof materials in liquid petroleum fuels. standard, it will result in the use of excessive barrier and explosion-proof materials, which will increase the cost of processing and use in vain

Description

technical field [0001] The invention relates to an explosion-proof performance measuring system and a measuring method thereof, in particular to an explosion-proof performance measuring system and a measuring method of barrier explosion-proof materials. Background technique [0002] Barrier and explosion-proof materials refer to metal or organic polymer materials as the matrix, which are made of mesh or other shapes after adding functional additives. This material is filled or installed in oil storage and transportation equipment, ground vehicles or armored equipment, aircraft or In the ship's fuel tank, it can quickly transfer heat, block the spread of flames, and prevent accidents such as explosions. Common barrier explosion-proof materials can be divided into honeycomb and spherical according to the shape; according to the material, they can be divided into metal (titanium alloy, copper alloy, aluminum alloy, etc.), non-metallic (polyether, polyester, nylon, etc.) and com...
