粉煤灰颗粒

粉煤灰的特征、综合利用的技术路线与产业化前景 ...

2012年4月27日高强粉煤灰烧结陶粒指经过成球和1000℃以上高温焙烧等工艺过程，将粉煤灰转变成具有高强轻质、连续级配、粒型合理、吸水率低、质量稳定、保温性能和泵送性粉煤灰按其颗粒分类可分为珠状颗粒和渣状颗粒两大类。在珠状颗粒中包括漂珠（常称空心微珠）、空心沉珠、复珠（子母珠）、密实沉珠（实心微珠）和富铁玻璃微珠等五大品粉煤灰的主要特性 - 百度文库

粉煤灰的综合利用研究现状及发展前景 - hanspub

粉煤灰又称飞灰，是一种颗粒非常细以至于能在空气中流动并能被特殊设备收集的粉状物质。粉煤灰呈灰褐色，通常呈酸性，比表面积在2500~7000 cm 2 /g，尺寸从几百微米(*10 从煤粉炉烟道气体中收集的粉末。粉煤灰按煤种和氧化钙含量分为f类和c类。 f类粉煤灰——由无烟煤或烟煤燃烧收集的粉煤灰。 c类粉煤灰——氧化钙含量一般大于10％，由褐粉煤灰混凝土应用技术规范[附条文说明]GB/T50146-2014

粉煤灰的颗粒形貌及其物理性质 - 百度学术

粉煤灰的颗粒形貌及其物理性质. 用扫描电镜观察了国内22种粉煤灰的形貌,发现粉煤灰由三种主要颗粒组成,即球形颗粒、不规则的熔融颗粒 (熔融玻璃体及多孔疏松熔融玻璃体)、炭粉煤灰理化性质及微观颗粒形貌研究. 采用XRD,SEM和LS230激光粒度分析仪对粉煤灰进行了一系列的研究,包括粉煤灰的矿物组成;粉煤灰的粒度分布;粉煤灰中微观颗粒形貌.粉煤粉煤灰理化性质及微观颗粒形貌研究 - 百度学术
