Embodiment Construction
[0017] The invention discloses a method for evaluating the flammability of metal powder and its organic solvent mixture. In order to make the advantages and technical solutions of the invention clearer and clearer, the invention will be described in detail below in conjunction with specific examples.
[0018] combine figure 1 Shown, the flammability evaluation method of metal powder and its organic solvent mixture of the present invention specifically comprises the following steps:
[0019] (1) First determine whether the mixture has a flowing organic solvent. If there is a flowing organic solvent, test its closed-cup flash point. If the flash point is less than 60°C, it is a flammable liquid; if there is no flowing organic solvent, the steps ( 2) the test;
[0020] (2) Test according to the test method for solid flammability in the "Manual of Tests and Criteria". If the burning rate is greater than 2.2 mm / s, it is regarded as a flammable solid. If the burning rate is less th...
