介绍了长余辉发光材料的特点和发光机理,通过在film上涂覆一层长余辉发光材料,可使film在暗室情况下具有较好的可视效果,应用于消防标志技术,将满足现代建筑规模化、高层化、复杂化以及临时建筑、特殊建筑的生命安全防灾体系要求。 The characteristics and luminescence mechanism of long afterglow luminescent materials are introduced. By coating a long persistence luminescent material on the film, the film can have better visual effect under the condition of dark room, and is applied to the fire sign technology and will meet the requirements of modern architecture Large-scale, high-level, complex and temporary buildings, special buildings, life safety disaster prevention system requirements.
