摘　　要：灰粉/CMC复合凝胶具有良好的流动性和封堵性,可以很好地对容易自燃的物体进行保护。通过实验发现,复合凝胶可以在5分钟内快速包裹自燃体表面。在密封环境对其封堵性进行了第二轮实验,通过与普通泡沫凝胶和水玻璃的对比,灰粉/CMC复合凝胶可更好地降低O2消耗量和CO生成量。The gray powder/CMC composite gel has good fluidity and plugging ability.It can protect the objects which are prone to spontaneous combustion.It is found by experiments that the composite gel can quickly wrap the surface of the autoignition body in 5 minutes.Second rounds of experiments were conducted on the sealing performance of the sealing environment.Compared with ordinary Foam Gel and sodium silicate,the gray powder/CMC composite gel can reduce O 2 consumption and CO production.
