(1) the product particle size of energy storage luminescent materials. Previously, the particle size can not be too fine, generally controlled at 180 ~ 300 mesh is appropriate, because too fine will destroy the intrinsic structure of its crystal, directly affecting its luminous brightness and afterg

DisadvantagesFirst, the current national standards, such as "Architectural Design Fire Code", "High-rise Civil Building Design Fire Code", "People's Air Defense Engineering Design Fire Code" and other codes are only some principle provisions, can not well guide the design, construction and fire supe

Evacuation signs are one of the important fire fighting facilities to ensure people's safe and quick escape after a fire. In the evacuation aisle and the main evacuation route on the ground or near the ground wall set luminous evacuation signs, can effectively help people in the smoke filled situati

Light-storing self-luminous materials are also called light-generating ultra-long afterglow light-storing materials, non-radioactive light-storing materials, and power-free self-luminous materials. The material actively absorbs and stores sunlight, light, ultraviolet light, stray light and other vis
