      ● 高阻燃隔火層電纜的阻燃機理
         Flame retardant mechanism of cables with fire retardant tapes

          主要原理
          韌性高阻燃隔火層電纜主要原理是在材料中添加了金屬水合物成份。韌性高阻燃隔火層所用的材料是集阻燃、吸熱、隔氧于一體的帶材??煞謩e實現低鹵低煙、無鹵低煙、阻燃電纜的高阻燃化,并能夠有效的提高電纜的阻燃等級。
          阻燃機理
          韌性高阻燃隔火層電纜的隔火層遇火層遇火分解成金屬氧化物和析出結晶水,金屬氧化物分解后形成網狀結構,對煙氣有一定的吸附作用。而析出的結晶水不但對煙粒起到明顯的沉降作用,而且還具有較好的吸熱效果。此外在燃燒過程中可以形成碳化結構,這種碳化層在電纜的低煙、阻燃化方面發揮了巨大的作用,吸熱作用延遲電纜本身開始燃燒時的燃燒速度和急劇上升的時間,由于碳化結構的形成,從而阻礙了氧氣的供給和可燃氣體的流動,因此抵制了電纜的燃燒。
      The main principle:
      The main principle of fire retardant layers in cables is the metal hydrate. Materials of fire retardant layer are flame retardant, endo-thermal, and oxygen insulating strips. By application of these strips, low halogen low smoke cables, halogen-free low smoke cables, or flame retardant cables of the high, can effectively improve their flame-retardant rating, respectively.
      Flame retardancy mechanism:
      Incase of fire, fire insulating layers in the fire retardant cables are decomposed into metal oxides and crystal water precipitation. The metal oxides form a network structure which can adsorp some flue gas after decomposition. The precipitation of crystal water has great effect not only on the settlement of smoke particles, but also in heat absorbing. In addition, a carbide structure is formed in the combustion process, and this carbonization layer plays a huge role in smoke reduction and flame retardency of cables. And its heat absorption function slowdowns the combustion rate but make a sharp rise in the humidity. The carbide structure hampers the oxygen supply and combustible gas flow, so the cable is resistance to combustion.
