 高填充量·精制—氢氧化镁Mg(OH)₂—阻燃剂

阻燃·无毒·无烟 (消烟)·阻滴·高平滑度·高物理强度

◎ #9119 Mg(OH)₂系经活性处理，受热分解时，分解出结晶水(H₂O)及活性氧化镁(MgO); 水能吸收大量潜热，降低材料在火焰中的温度，同时抑制可燃性气体，进一步分解，阻止燃烧。活性氧化镁(MgO) 能催化氧化烟量，大大减少生烟量和烟逸出的速度，同时能吸收大量的物质—高分子自由基和碳(燃烧时，沉积为灰)，阻止燃烧，并延迟材料引燃时间，亦具有极优异的抑制—具毒性之HCL的生成·降低人员伤害。

◎ #9119 Mg(OH)₂为超细无粗颗粒，经表面处理活性，高细度其**的表面平滑度·高物理强度…等。是高填充量的基本条件，建议用量：对总量约20～40%，依材质·订单要求而定。
