防爆板是由增强纤维水泥板表面加压镀锌钢材料构成的耐火防爆材料。主要用于防爆隔墙、防爆天花板、防爆排烟风管、电缆管、防爆电缆保护、防爆门和钢结构防爆保护等多种系统。

防爆板轻盈、强度、冲击、稻瘟病抗性、耐久性与特殊防火，使得消防人员可以尽量的免除一场火灾，***社会的生命和财产安全。全世界在各种行业,包括电站、核电、石油化工、制药、钻井平台、仓库、机场、铁路和地铁设施。

防爆板特点

1、阻燃性（持续4个小时的燃烧试验）、抗爆性、抗冲击性

2、防潮和消防、抗震、质量轻、抗腐蚀、幅面较大

3、耐候性能（不随着气温的变化改变）、高电阻、吸音、抗冻

防爆板安装与固定

（1）根据设计图纸和实际施工情况，对板材进行切割和开孔，必要时现场作倒角，防爆板的两长边都已作好倒角处理，但当墙体高于2400mm时，防爆板水平接缝的短边必须现场倒角，以便更好地处理接缝。

（2）在防爆板面上弹线并标出自攻螺钉固***，同时预钻凹孔（孔径比自攻螺钉头大1mm～2mm，孔深1mm～2mm）。自攻螺钉距板边15mm，距板角50mm，自攻螺钉间距200mm～250mm。

（3）隔墙铺板时，一般采用纵向铺设，即板的长边固定于竖龙骨上；板材对接时要自然靠近，不能强压就位；墙体两面的接缝应相互错开，不能落在同一根龙骨上。

（4）固定防爆板时，板与龙骨应作预钻孔，孔径比自攻螺钉直径小1mm，防爆板用自攻螺钉固定，固定时应从板的中间部向周边固定，所有螺钉头均应沉入板面1mm。

（5）安装门窗周围板时，板缝不能落在与地面水平和垂直框龙骨上，以避免门窗的经常开关产生振动而造成板缝开裂。
