从彩钢板的材料分析来看，彩钢夹芯板已彩色涂层钢板为面材，芯材主要有聚苯乙聚、氨酯、岩棉三种。
From the material analysis of color steel plate, the color steel sandwich plate has been color coated steel plate as the surface material, and the core materials mainly include polyphenylene glycol polymer, urethane and rock wool.
目前，大部分彩钢板内保温材料为聚苯乙烯和聚氨酯，他们具有重量轻、操作工艺简单和低成本等优势，但是其燃点低、阻燃性差。聚苯乙烯的燃点是345℃，而木材的燃点是250℃至300℃，仅比木材燃点高一点，而聚氨酯燃点仅在130℃左右。
At present, most of the internal insulation materials of color steel plate are polystyrene and polyurethane. They have the advantages of light weight, simple operation process and low cost, but they have low ignition point and poor flame retardancy. The ignition point of polystyrene is 345 ℃, while that of wood is 250 ℃ to 300 ℃, which is only a little higher than that of wood, while that of polyurethane is only about 130 ℃.
聚苯乙烯和聚氨酯在燃烧时会产生大量的浓烟，其成分主要是一氧化碳、氰化氢等，烟气毒性较大。
Polystyrene and polyurethane will produce a large amount of thick smoke when burning. Its components are mainly carbon monoxide, hydrogen cyanide, etc., which is highly toxic.
彩钢板火灾具有蔓延速度快、烟火蔓延途径多、容易形成立体火灾、燃烧产物中含有毒气体、扑救比较困难和容易造成建筑坍塌等特点。
Color steel plate fire has the characteristics of fast spread speed, many ways of fireworks spread, easy to form three-dimensional fire, toxic gas in combustion products, difficult fire fighting and easy to cause building collapse.
在彩钢板不断进步的时代，想要彻底防火，使用的安全，就得选用防火性能好的彩钢板，例如：精钢覆膜瓦！
In the era of continuous progress of color steel plate, if you want to completely prevent fire and use safety, you have to choose color steel plate with good fire resistance, such as precision steel coated tile!
