<div class="content" style="margin-bottom:30px;"><p><a href="http://www.cnbtv.cn/"><b>阻火?/b></a>的性能是否能达到预期的效果，起到阻火的作用，必须对<a href="http://www.cnbtv.cn/"><b>阻火?/b></a>进行测试?br />
<a href="http://www.cnbtv.cn/"><b>阻火?/b></a>除具备有一定的机械强度外，还要经过阻爆和耐烧的试验，并应达到试验标准的要求?br />
阻爆试验即在一定距离内将试验装置内的可燃气体点燃，所产生的火焰或火花不能穿过阻火器而被阻止和熄灭，这种试验称为阻爆试验?br />
耐烧试验是在没有回燃的条件下，可燃气体火焰通过阻火层并在阻火层上面持续燃烧。阻火层能够承受一定时间的火焰燃烧而不被烧坏，这种试验称为耐烧试验?br />
<a href="http://www.cnbtv.cn/"><b>阻火?/b></a>根据使用的目的，可以同时具有阻爆性能和耐烧性能，也可以只具有阻爆性能或耐烧性能。因?a href="http://www.cnbtv.cn/"><b>阻火?/b></a>的阻爆性能和耐烧性能是对阻火器进行测试鉴定的主要项目。没有进行过这种测试鉴定的阻火器是不能使用的?/p></div>
