燃烧也就是氧化，一般情况我司生产的FRP采光板氧化数≤21％属易燃性，遇到明火时即主动燃烧，温度越高越容易燃烧。因此一旦遇到火灾，采光板能快速燃烧完，成为一个排烟带，根据不溶不熔可溶可熔性，东宏公司生产的FRP采板属热固性产品，燃烧时不会产生融滴现象(由国家消防装备质量监督检验中心出具质量测试报告)，氧指数≥28％时为阻燃刑采光板，即离火能自熄，不是不燃而是被动燃烧。当其接触火焰时出现温度升高、热分解、着火、持续燃烧等现象。FRP采光板和许多材料一样强度随温度升高而下降，当温度上升到某一值时，强度急剧下降。另外，不像其他材料在低温时变脆，FRP的低温性能很好，在-70℃时冲击强度有随温度下降而上升的趋势。因此FRP采光板在20℃-95℃的情况下FRP采光板不会老化、变黄、开裂或软化。

The combustion is oxidation, in general our production of FRP lighting plate oxidation number is less than or equal to 21% is flammable, encountered fire is active combustion, high temperature is easy to burn. Therefore, once encountered fire, lighting board can quickly burn out, become a smoke, according to insoluble and infusible soluble fusibility, Donghong company production of FRP mining board belongs to thermosetting products, combustion does not produce melting drop phenomenon (quality test report issued by the national fire equipment quality supervision and inspection center), the oxygen index is greater than or equal to 28% for the punishment of flame retardant lighting plate, from the fire can be self extinguishing, not passive but fuel combustion. When exposure to flame, temperature rise, thermal decomposition, ignition, continuous combustion and so on. Like many materials, the FRP light intensity decreases with increasing temperature, and when the temperature rises to a certain value, the intensity drops sharply. In addition, unlike other materials which are brittle at low temperatures, FRP has very low temperature performance. At -70, the impact strength increases with decreasing temperature. Therefore, the FRP lighting board will not aged, turn yellow, crack or soften when the FRP lighting board is at 20 degrees -95 degrees centigrade.
