使用泡沫彩钢板也需要注意的火灾危害

天物集团专注彩涂卷行业17年——泡沫彩钢板的火灾危害_辽宁彩涂板加工生产厂家_天物集团请拨打网站上方电话咨询

一是泡沫彩钢板的隐患。

1.高温和烟雾积聚使灭火困难。彩钢板结构施工相对封闭。聚氨脂泡沫塑料、聚苯乙烯泡沫塑料等聚合物夹层材料燃烧时,会产生大量高温浓烟,使建筑物在短时间内充满烟雾,积聚大量热量,给消防工作带来很大困难。

2.耐火性差,易形成大面积坍塌。彩钢在室温下是一种不可燃材料,但经火焰烘烤后其强度会迅速下降。特别是大跨度建筑发生火灾时,彩钢构件容易因高温变形变形,导致建筑大规模倒塌。
3、施工企业规模大,易形成三维燃烧火灾。彩钢建筑公司以其工作强度高、重量轻、施工方便等特点,在建筑市场上得到了大规模的发展。发生火灾时,大量烟气热量通过各种管道和通道向上扩散,容易形成三维燃烧状态。
4、易造成人员伤亡。一旦发生火灾,彩钢板中填充泡沫的易燃高分子材料中的有毒有害气体或杂质逐渐增多,使人们受到越来越多的威胁。
5.彩钢板房使用的电线电缆多为假冒伪劣产品,易老化。由于电线电缆埋在夹层中,老化电线电缆容易点燃夹层中的芯材。
2、 防火措施
1、在使用和管理过程中,一些主要热源和火源不应靠近彩钢板,并与企业保持一定距离。
2.如果你想在彩钢房里装饰厨房,你需要隔热。
3.电线电缆不得穿过彩钢板。如果需要穿过保护套管、插座和开关箱,应采用金属镀锌箱和透明包装方式。
4.室内外均应配备简单的消防设备,并在条件允许时安装火灾报警器,以便于人员快速疏散。
5、公安部消防部门要求,不得在托儿所、幼儿园、养老院、福利院、寄宿学校、医院等人口密集场所修建甲级以下彩钢板;采用彩钢板建造的人口密集场所,低于a级要求的,不得通过消防设计审查、验收或抽检;所有采用低于a级要求的彩钢板建造的公众聚集场所,在使用和运行前不得通过消防安全检查;对检查中发现的用彩钢板搭建的人口密集场所,凡低于a级要求的场所一律临时封闭,并责令改变用途。不能更改的必须删除。
One is the hidden danger of foam color steel plate.
1. High temperature and smoke accumulation make it difficult to put out the fire. The construction of color steel plate structure is relatively closed. When polymer sandwich materials such as polyurethane foam and polystyrene foam are burned, a lot of high temperature and dense smoke will be generated, which will make buildings smoke in a short time and accumulate a lot of heat, which will bring great difficulties to fire fighting.
2. Poor fire resistance, easy to form large-area collapse. Color steel is a non combustible material at room temperature, but its strength will decrease rapidly after flame baking. Especially in case of fire in long-span buildings, color steel components are easy to deform due to high temperature, resulting in large-scale collapse of buildings.
3. The construction enterprise is large in scale and easy to form three-dimensional combustion fire. Caigang construction company has developed on a large scale in the construction market because of its high work intensity, light weight and convenient construction. In case of fire, a large amount of flue gas heat diffuses upward through various pipes and channels, which is easy to form a three-dimensional combustion state.
4. It is easy to cause casualties. In case of fire, toxic and harmful gases or impurities gradually increase in the flammable polymer materials filled with foam in color steel sheets, which makes people more and more threatened.
5. The wires and cables used in the color steel plate house are mostly fake and inferior products, which are easy to aging. As wires and cables are buried in the interlayer, aging wires and cables are easy to ignite the core material in the interlayer.
2. Fire prevention measures
1. In the process of use and management, some main heat sources and fire sources should not be close to the color steel plate, and keep a certain distance from the enterprise.
2. If you want to decorate the kitchen in the color steel room, you need heat insulation.
3. Wires and cables shall not pass through color steel plate. If it is necessary to pass through protective sleeves, sockets and switch boxes, metal galvanized boxes and transparent packaging shall be used.
4. Simple fire-fighting equipment shall be equipped indoors and outdoors, and fire alarm shall be installed when conditions permit, so as to facilitate rapid evacuation of personnel.
5. According to the requirements of the Fire Department of the Ministry of public security, color steel plates below grade A shall not be built in densely populated places such as nurseries, kindergartens, nursing homes, welfare homes, boarding schools and hospitals; Densely populated places built with color steel plates, which are lower than class a requirements, shall not pass the fire design review, acceptance or sampling inspection; All public gathering places constructed of color steel plates lower than class a requirements shall not pass the fire safety inspection before use and operation; For densely populated places built with color steel plates found in the inspection, all places lower than class a requirements shall be temporarily closed, and the use shall be ordered to change. Items that cannot be changed must be deleted.
