粉煤灰制保温材料探讨

An lnquiry into a New Heat Insulator Made from Powdery Coal Ash

粉煤灰是电力系统排出的一种固体废物,主要含有硅、铝、钙、镁等的氧化物,与各保温材料主要成分相似。若加入一些辅助材料调节,即可制得性能优异的新型保温材料—粉煤灰矿棉。这是粉煤灰综合利用的一条新路,具有较高的经济和社会效益。

The ash of powdery coal is a solid waste excreted from power system. It contains mainly the oxides of silicon, aluminium, calcium, magnesium, etc., similar to that of vari- ous kinds of heat insulators. If it is regulated by adding some auxiliary materials, a mineral wool of powdery coal ash as a new type of heat insulator with excellent performance can be made. This is a new route of comprehensive utilization of powdery coal ash, which has fairly high economic and social benefits.
