Description

一种轻质高强粉煤灰陶粒的制备方法
技术领域
本发明涉及建筑材料制备领域，特别涉及一种轻质高强粉煤灰陶粒的制备方法。
背景技术
粉煤灰陶粒的最大特点是外表坚硬，而内部有许许多多的微孔，这些微孔赋予陶粒质轻的特性。用它配制出来的陶粒混凝土相比普通混凝土具有以下优点：1、密度小、质轻；2、保温、隔热；3、耐火性好；4、抗震性能好；5、抗冻性能和耐久性能好；6、造价低。近几年国家大力发展绿色建筑材料，倡导节能建筑。开发应用品质优良、节能环保、功能良好的新型建筑材料，才能适应时代的发展。粉煤灰陶粒混凝土能满足墙体自保温***，可以省去做墙体保温层，因此粉煤灰陶粒的生产和应用必将获得较快的发展。
传统粉煤灰陶粒的生产方法以粉煤灰、粘土为原料，采用成球盘成球，经过回转窑高温煅烧进行生产。传统方法生产的粉煤灰陶粒筒压强度偏低、质量很不稳定且吸水率较高，市面上陶粒性能600kg/m3对应筒压强度4Mpa；700kg/m3对应筒压强度5Mpa；800kg/m3对应筒压强度6Mpa。
发明内容
本发明的目的在于提供了轻质高强粉煤灰陶粒的配方及其制备方法。制备出稳定的粉煤灰陶粒，600kg/m3粉煤灰陶粒对应筒压强度5.6～5.8Mpa；700kg/m3粉煤灰陶粒对应筒压强度6.6～6.9Mpa；800kg/m3粉煤灰陶粒对应筒压强度7.9～8.2Mpa，产品性能远优于市面上陶粒的性能。解决了粉煤灰陶粒筒压强度低、质量不稳定、吸水率高等问题。
为实现上述目的，本发明提供如下技术方案：
本申请实施例公开了一种轻质高强粉煤灰陶粒的制备方法，依次包括如下步骤：
S1 将粉煤灰、膨润土、玻璃粉、稻糠按质量比30～55∶40～55∶5∶0～10称取后投入强制搅拌混料机混合均匀；
S2 将步骤S1所得物料进行球磨；
S3 将步骤S2所得物料输送至圆盘喷雾造粒机进行造粒；
S4 将步骤S3所得生料球投入回转窑中进行煅烧，得到轻质高强粉煤灰陶粒。
优选的，在上述轻质高强粉煤灰陶粒的制备方法中，所述步骤S1中，粉煤灰、膨润土、玻璃粉、稻糠质量比为36～50∶42～52∶5∶2～8。
优选的，在上述轻质高强粉煤灰陶粒的制备方法中，所述步骤S2中，物料球磨至平均粒度小于150微米。
优选的，在上述轻质高强粉煤灰陶粒的制备方法中，所述步骤S3中，控制生料球的含水率为16～20%，直径为4～16mm。
优选的，在上述轻质高强粉煤灰陶粒的制备方法中，所述步骤S4中，煅烧温度为1200～1350℃。
优选的，在上述轻质高强粉煤灰陶粒的制备方法中，所述步骤S4中，经历全窑时间为50～60min，窑的转速为1.2～2.4转/min。
优选的，在上述轻质高强粉煤灰陶粒的制备方法中，所述步骤S1中，粉煤灰与膨润土中SiO2、Al2O3、Fe2O3的质量百分比之和为65%～85%。
优选的，在上述轻质高强粉煤灰陶粒的制备方法中，所述步骤S1中，玻璃粉是废旧玻璃制品进破碎、粉磨后，过100目筛所得。
优选的，在上述轻质高强粉煤灰陶粒的制备方法中，所述步骤S1中，稻糠粉是稻谷制米过程中去除净米后的部分经过粉磨加工，过100目所得。
本发明的优点在于：
1、有效的利用了粉煤灰、玻璃渣、稻糠等工农业废弃物，粉煤灰中SiO2可以减少膨润土的分散度，使膨胀性能降低；Fe2O3有助于降低膨润土颗粒的溶化温度，并参加汽化过程，使其更好地膨胀；Al2O3含量过高会使烧成温度增高，从而增加成本不利于生产；玻璃粉在陶粒烧结中具有强烈的助熔作用；稻糠粉在陶粒烧结中具有强烈的发气作用。
2、本发明以玻璃粉为助熔剂，稻糠粉为发气剂，配合成陶成分粉煤灰和膨润土，进行合理配比，生产出的粉煤灰陶粒产品性能远优于市面上陶粒的性能，解决了粉煤灰陶粒筒压强度低、质量不稳定、吸水率高等问题，具有显著的经济效益。
