Abstract
Description
Technical Field
[0001] The utility model relates to the field of combustion test tool design, in particular to a material flame retardant testing machine. Background Art
[0002] Flame retardant materials are materials that can inhibit or delay combustion and are not easy to burn themselves. As the safety requirements in home, industry and other fields become higher and higher, the scope of use of flame retardant materials is also becoming wider.
[0003] The most direct way to test the performance of flame retardant materials is to use open flames to obtain flame retardant data by using different combustion temperatures, flame sizes, and combustion distance tests. Currently, the most common method is to use a combustion gas bottle connected to an ignition gun assembly to conduct a combustion test, but most of the height adjustments of this design are manual, and the adjustment length control is not accurate.
[0004] At present, most of the external flame retardant test equipment or flame retardant test chambers lack fire extinguishing and monitoring structures. The monitoring structure mainly monitors harmful gases. If the concentration of harmful gases exceeds the standard during the combustion of materials, a reminder is required. At the same time, if a fire exceeds the test range, it needs to be extinguished in time. The combination of the two can improve safety and provide a safety protection for the test.
