| 摘 要： | 通过扫描电子显微镜对工业型煤的微观结构进行分析 ,发现工业型煤的冷强度是因粉煤颗粒间分布有凝胶体和各种形态的晶体而形成 ,其强度的大小则取决于形成的晶体在粉煤颗粒间是否形成网络、分布是否均匀、凝胶体包裹煤粒是否密实等因素

| Abstract: | Based on the laboratory tests and theoretical analysis,the microstructure of briquette has been studied,and the mechanism of the cold strength of the industrial briquette have been established.A large amount of gel and several of crystals have been found on the surface of the coal granules and among the coal granules.The more crystals are formed or the better the gel is distributed,the higher the strength of the briquette is. |
