Different batches of materials have certain differences in flame retardancy. Therefore, before producing carbon fiber rollers, it is necessary to first test the flame retardancy of the carbon fiber rollers to ensure the stability and reliability of the carbon fiber roller materials.
[0003] In the related technology, the operator first places the carbon fiber roller to be tested inside the test box and fixes the carbon fiber roller at the corresponding position of the test box. The operator then performs a combustion test on the roller in the test box. After a period of time, the roller is taken out and the relevant data of the roller is tested to obtain the results of the flame retardancy of the roller.
[0004] With respect to the above-mentioned related technologies, the roller is fixed inside the flame retardant test box, and only a single position of the roller can be tested accordingly, and multiple positions of the roller cannot be tested at different temperatures.
