摘要
研究了纳米二氧化硅、硅微粉、石墨、纳米级铜粉对于蛋白泡沫的发泡能力及热稳定性的影响,并且测试了形成的复合泡沫的热稳定性,结果表明:将耐烧粉体直接添加进灭火泡沫中有望增强其抗烧能力和灭火性能。在常温下纳米二氧化硅以及纳米级铜粉能与蛋白泡沫较好的结合为复合泡沫,添加测试粉体后复合泡沫的热稳定性均有明显增强,其中添加纳米二氧化硅和纳米级铜粉的复合泡沫整体性能良好,无泡沫排液和聚并现象,可以起到良好的隔热作用。
Effects of nano-silica, silica powder, graphite, nano copper powder on protein foaming ability and heat stability of foam were investigated; thermal stability of formed composite foam was tested. The results show that, to add burning resistance powders into the fire fighting foam is expected to increase its fire resistance and fire-fighting performance;Nano-silica and nano copper powders in normal temperature can better combine with protein foam to form composite foam, and the thermal stability of the composite foam can be increased dramatically; The composite foam has good overall performance, has not bubble fluid and the coalescence phenomenon.
