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.

　　“一旦發(fā)生火災(zāi)，合格的消防產(chǎn)品可以起到滅火或控制火勢(shì)蔓延的作用。”像滅火器一樣可以撲滅初始火災(zāi)，將危險(xiǎn)情況控制住。但是，一些不法分子生產(chǎn)個(gè)別假冒偽劣消防產(chǎn)品，嚴(yán)重威脅人民生命財(cái)產(chǎn)安全。專(zhuān)家說(shuō)，真正的防火涂料可以具有很好的防火保溫效果，可以有效地阻燃60分鐘至120分鐘，通常用于施工易燃易爆材料及通風(fēng)管道、電纜、電線(xiàn)、建筑鋼結(jié)構(gòu)等方面的防火保護(hù)。“一旦發(fā)生火災(zāi)，涂有合格防火涂料的建筑物將更加防火，并為人們提供更多寶貴的逃生時(shí)間。”

　　"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."

　　“火災(zāi)現(xiàn)場(chǎng)溫度一般在800到1000攝氏度以上。今天我們模擬的是500攝氏度。在500攝氏度時(shí)，鋼結(jié)構(gòu)會(huì)變形。“被加熱的鋼板不僅會(huì)傳遞熱量，還會(huì)點(diǎn)燃旁邊的可燃材料，如果是鋼結(jié)構(gòu)，就會(huì)失去承載能力，不安全，甚至?xí)顾?rdquo;合格的防火涂料在高溫下加熱形成“保護(hù)層”，然后實(shí)驗(yàn)者繼續(xù)燃燒涂有假冒偽劣防火涂料的鋼板。在高溫加熱后,鋼結(jié)構(gòu)的表面有一個(gè)細(xì)微的變化可以看出,表面涂層開(kāi)裂。實(shí)驗(yàn)者說(shuō),“假火后涂層基本上不會(huì)改變,不玩阻燃絕緣的作用,它類(lèi)似于裸鋼加熱時(shí)間”。

　　"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.".

　　本檢測(cè)超薄防火涂料，主要由基材、阻燃填料、顏料和添加劑等組成。防火板批發(fā)廠(chǎng)家按照防火涂料阻燃機(jī)理，超薄鋼結(jié)構(gòu)防火涂料屬于膨脹型防火涂料。防火機(jī)理的涂層吸收熱量擴(kuò)大泡沫消防源的作用下,氣體排放non-combustion終止自由基的氧化或稀釋氧氣在涂層表面,泡沫層有較低的熱傳導(dǎo)和吸收因素,扮演一個(gè)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.
