好的防火板在火灾逃生上还是很有优势的

来源:/ 日期:2020-05-07
     现在一些消防监督执法人员对消防产品进行了检查,并对防火涂料做了一组实验。实验表明,在高温燃烧时,涂有合格防火涂料的钢材会起泡膨胀,即产生隔离层,这给人们从火灾中逃生、组织抢救争取了宝贵的时间。
  Now some fire supervision and law enforcement personnel have inspected the fire products, and made a group of experiments on the fire retardant coating. The experiment shows that the steel coated with qualified fire retardant coating will bubble and expand when burning at high temperature, that is to say, an isolation layer will be formed, which will give people precious time to escape from the fire and organize rescue.
  “一旦发生火灾,合格的消防产品可以起到灭火或控制火势蔓延的作用。”像灭火器一样可以扑灭初始火灾,将危险情况控制住。但是,一些不法分子生产个别假冒伪劣消防产品,严重威胁人民生命财产安全。专家说,真正的防火涂料可以具有很好的防火保温效果,可以有效地阻燃60分钟至120分钟,通常用于施工易燃易爆材料及通风管道、电缆、电线、建筑钢结构等方面的防火保护。“一旦发生火灾,涂有合格防火涂料的建筑物将更加防火,并为人们提供更多宝贵的逃生时间。”

  "In the event of a fire, qualified fire-fighting products can play a role in extinguishing or controlling the spread of the fire." Like a fire extinguisher, it can put out the initial fire and control the dangerous situation. However, some lawbreakers produce some fake fire-fighting products, which seriously threaten the safety of people's lives and property. Experts said that the real fire-proof coating can have a good fire insulation effect, can effectively flame retardant for 60 to 120 minutes, and is usually used for the construction of flammable and explosive materials and ventilation pipes, cables, wires, building steel structures and other aspects of fire protection. "In the event of a fire, buildings coated with a qualified fire retardant coating will be more fireproof and provide more valuable escape time for people."
  “火灾现场温度一般在800到1000摄氏度以上。今天我们模拟的是500摄氏度。在500摄氏度时,钢结构会变形。“被加热的钢板不仅会传递热量,还会点燃旁边的可燃材料,如果是钢结构,就会失去承载能力,不安全,甚至会倒塌。”合格的防火涂料在高温下加热形成“保护层”,然后实验者继续燃烧涂有假冒伪劣防火涂料的钢板。在高温加热后,钢结构的表面有一个细微的变化可以看出,表面涂层开裂。实验者说,“假火后涂层基本上不会改变,不玩阻燃绝缘的作用,它类似于裸钢加热时间”。
  "The temperature of the fire scene is generally above 800-1000 ℃. Today we are simulating 500 degrees Celsius. At 500 ℃, the steel structure will deform. "The heated steel plate will not only transfer heat, but also ignite the combustible materials nearby. If it is a steel structure, it will lose its bearing capacity, be unsafe and even collapse." The qualified fire retardant coating is heated to form a "protective layer" at high temperature, and then the experimenter continues to burn the steel plate coated with fake fire retardant coating. After high temperature heating, there is a slight change on the surface of the steel structure, which can be seen that the surface coating cracks. The experimenter said, "the coating will not change basically after the false fire, and it does not play the role of flame-retardant insulation, which is similar to the heating time of bare steel.".
  本检测超薄防火涂料,主要由基材、阻燃填料、颜料和添加剂等组成。防火板批发厂家按照防火涂料阻燃机理,超薄钢结构防火涂料属于膨胀型防火涂料。防火机理的涂层吸收热量扩大泡沫消防源的作用下,气体排放non-combustion终止自由基的氧化或稀释氧气在涂层表面,泡沫层有较低的热传导和吸收因素,扮演一个角色在防火。
  The ultra-thin fire retardant coating mainly consists of base material, flame retardant filler, pigment and additive. According to the fire retardant mechanism of fire retardant coating, ultra thin steel structure fire retardant coating belongs to intumescent fire retardant coating. The fireproof mechanism of the coating absorbs heat and expands the role of the foam fire source. The gas emission non-combustion terminates the oxidation of free radicals or dilutes oxygen on the coating surface, and the foam layer has a lower thermal conductivity and absorption factor, playing a role in fire prevention.
