彩钢板又叫建筑用金属面绝热夹芯板，上下两层为厚度不小于0.5mm的彩色涂层金属薄板，中间芯材可采用可燃有机保温材料如聚苯乙烯泡沫塑料、聚氨酯泡沫塑料以及不燃保温材料如岩棉等。

耀世娱乐　　Color steel plate is also called metal surface thermal insulation sandwich panel for building. The upper and lower layers are color coated metal sheets with a thickness of not less than 0.5mm. The middle core material can be combustible organic thermal insulation materials such as polystyrene foam plastic, polyurethane foam plastic and non combustible thermal insulation materials such as rock wool.

耀世娱乐　　彩钢房是一种以轻钢H型钢、槽钢为骨架，以加芯板为墙体材料，通过空间组合，构件采用螺栓连接或焊接的经济型房屋。这种房屋可方便快捷地进行组装和拆卸，实现了临时建筑的通用标准化。

　　Color steel house is an environmentally friendly and economical building with light steel H-shaped steel and channel steel as the skeleton, core board as the wall material, and bolted or welded components through spatial combination. This type of house can be easily and quickly assembled and disassembled, achieving universal standardization of temporary construction.

　　为何彩钢板建筑会如此危险？

耀世娱乐　　Why are color steel plate buildings so dangerous?

　　彩钢板按内部夹芯材料主要分为：聚氨酯夹芯板、聚苯乙烯（EPS）夹芯板、岩棉夹芯板、玻璃丝绵夹芯板等。其中,防火性能的是岩棉夹芯板和玻璃丝绵夹芯板，属于防火性能A级建筑材料，但这类夹芯板较高。一些使用单位为了减少成本，往往选用低廉的聚氨酯夹芯板或聚苯乙烯（EPS）夹芯板，而这种可燃夹芯材料在燃烧时将产生有毒气体，极易酝成事故。

耀世娱乐　　Color steel plates are mainly divided into polyurethane sandwich panels, polystyrene (EPS) sandwich panels, rock wool sandwich panels, glass wool sandwich panels, etc. according to their internal sandwich materials. Among them, the best fireproof performance is rock wool sandwich panel and glass wool sandwich panel, which belong to Class A fireproof building materials, but these sandwich panels are relatively expensive. Some users often choose low-priced polyurethane sandwich panels or polystyrene (EPS) sandwich panels to reduce costs, but these combustible sandwich materials will produce toxic gases during combustion, which can easily lead to accidents.

　　在搭建彩钢房过程中，聚苯乙烯（EPS）、聚氨酯处于裸露状态，容易被电焊、气焊、切割机等明火作业直接引燃。彩钢房在建成使用后，乱接电线，临近热源、火源，很容易使夹层中的聚苯乙烯（EPS）或聚氨酯着火。

耀世娱乐　　During the construction of color steel houses, polystyrene (EPS) and polyurethane are exposed and easily ignited by open flame operations such as welding, gas welding, and cutting machines. After the construction and use of color steel houses, randomly connecting wires and being close to heat and fire sources can easily cause the polystyrene (EPS) or polyurethane in the interlayer to catch fire.

　　搭建彩钢房多用于临时用房，其采用的电线、电缆等多是廉价商品，由于电线、电缆横穿夹芯层或沿着板材边缘铺设，一旦老化或破皮极易发生漏电短路，从而引燃夹层中的可燃芯材。

　　Building color steel houses is often used for temporary use, and the wires, cables, and other materials used are mostly cheap goods. Due to the fact that the wires and cables cross the sandwich layer or are laid along the edges of the board, once they age or break, they are prone to electrical leakage and short circuits, which can ignite the combustible core materials in the sandwich layer.

　　彩钢房一旦发生火灾，夹芯可燃材料在彩钢板夹层内燃烧、蔓延途径多，火势发展快，燃烧猛烈，产生大量剧毒浓烟，人员难以逃生，且扑救困难。

　　Once a fire occurs in a color steel house, the combustible materials in the sandwich layer will burn and spread through multiple pathways within the color steel plate interlayer. The fire will spread rapidly and fiercely, producing a large amount of highly toxic and thick smoke, making it difficult for personnel to escape and for firefighting to be carried out.

　　彩钢板建筑火灾的特点

耀世娱乐　　Characteristics of color steel plate building fires

耀世娱乐　　一、建筑耐火性能差，容易坍塌

耀世娱乐　　1、 Poor fire resistance and easy collapse of buildings

　　彩钢板建筑大多使用钢结构沉重火灾时火场温度可达800~1000℃超过钢结构失去静态平衡稳定性的500℃的临界温度。在承载负荷的情况下，裸露的钢结构很快会变形及局部破坏，造成建筑坍塌。普通彩钢板房一般在发生火灾后10分钟左右就会丧失承载能力而垮塌，不利于人员疏散和抢救物资。

　　Most color steel plate buildings use steel structures. During heavy fires, the temperature at the fire site can reach 800-1000 ℃, exceeding the critical temperature of 500 ℃ at which the steel structure loses its static equilibrium stability. Under load-bearing conditions, exposed steel structures will quickly deform and suffer local damage, leading to building collapse. Ordinary color steel panel houses usually lose their load-bearing capacity and collapse about 10 minutes after a fire occurs, which is not conducive to personnel evacuation and rescue materials.

　　二、板芯材料易点燃，蔓延迅速

耀世娱乐　　2、 Core material is easy to ignite and spreads rapidly

　　彩钢板的板芯填充材料多数为聚氨酯、聚苯乙烯等易燃可燃材料，燃点低、阻燃性差，一旦遇到高温火花、电线短路或明火作用会立刻燃烧，且材料的蜂窝状结构会加大与空气的接触面，导致猛烈燃烧。

耀世娱乐　　The core filling material of color steel plate is mostly flammable and combustible materials such as polyurethane and polystyrene, with low ignition point and poor flame retardancy. Once it encounters high-temperature sparks, wire short circuits or open flames, it will immediately burn, and the honeycomb structure of the material will increase the contact surface with air, leading to violent combustion.

　　三、建筑内通道狭窄，影响疏散

　　3、 The narrow passage inside the building affects evacuation

　　很多单位为了追求使用面积，没有留出符合规范要求的通道和疏散空间，有些甚占用疏散通道搭建彩钢房，一旦发生火灾，人员疏散受阻，后果不堪设想。

耀世娱乐　　Many units, in order to pursue the use of space, do not leave safety passages and evacuation spaces that meet regulatory requirements. Some even occupy safety evacuation passages to build color steel houses. Once a fire occurs, personnel evacuation is obstructed, and the consequences are unimaginable.

　　四、燃烧产物毒性大，逃生困难

耀世娱乐　　4、 The toxicity of combustion products is high, making escape difficult

　　彩钢板板芯填充物采用的聚苯乙烯和聚氨酯为高分子聚合材料，燃烧会产生大量浓烟，含有一氧化碳和氰化氢等有毒气体，具有很强的毒性和刺激性，容易造成伤亡事故。

耀世娱乐　　The filling material for the color steel plate core is made of polystyrene and polyurethane, which are high molecular weight polymer materials. Combustion produces a large amount of thick smoke and contains toxic gases such as carbon monoxide and hydrogen cyanide, which are highly toxic and irritating, and can easily cause casualties.

　　五、火场不利因素多，扑救困难

耀世娱乐　　5、 There are many unfavorable factors in the fire scene, making it difficult to extinguish

　　彩钢建筑火灾在扑救过程中，水和灭火剂只能喷到彩钢板外层的板面上，不能直接作用于夹层里的燃烧物

　　During the firefighting process of color steel building fires, water and fire extinguishing agents can only be sprayed onto the outer surface of the color steel plate, and cannot directly act on the combustibles in the interlayer
