随着科学技术的深入发展,人们对事物客观规律的认识不断完善,对材料燃烧特性内涵的理解和定义也从仅指火焰蔓延、火焰传播扩展到燃烧过程的热释放速率、热释放量、烟浓度和燃烧生成物的毒性等。因此人们在线缆的阻燃技术开发研究中,除了考虑降低线缆的火焰传播速度外,还同时考虑如何降低燃烧中烟的浓度以及烟气产生的毒性。日前常见的阻燃线缆有普
With the deepening of science and technology, people’s understanding of the objective law of things has been continuously improved. The understanding and definition of the connotation of the material’s combustion characteristics has also changed from simply referring to flame spread, spread of flame to the rate of heat release, heat release, Concentration and toxicity of combustion products. Therefore, people in the cable flame retardant technology research and development, in addition to consider reducing the flame propagation rate of the cable, but also consider how to reduce the concentration of smoke in the combustion and the toxicity of flue gas. A few days ago common flame retardant cable Pu
