Description

一种超轻高强粉煤灰轻集料 技术领域
本发明涉及粉煤灰处理及资源化利用技术领域,具体地涉及一种超轻高强粉煤灰轻集料。
背景技术
1、粉煤灰是燃煤发电的固体废弃物,我国2015年产量6亿多吨,综合利用率约为70%,累计积存量30多亿吨,成为我国当前排量较大的工业废渣之一。大量的粉煤灰不加处理,就会产生扬尘,污染大气;若排入水系会造成河流淤塞,而其中的有毒化学物质还会对人体和生物造成危害。而将粉煤灰资源化利用受到国家和各地方政府的大力支持;
2、陶粒具有优异的性能,如密度低、筒压强度高、孔隙率高,软化系数高、抗冻性良好、抗碱集料反应性优异等。特别由于陶粒密度小,内部多孔,形态、成分较均一,且具一定强度和坚固性,因而具有质轻,耐腐蚀,抗冻,抗震和良好的隔绝性等多功能特点。利用陶粒这些优异的性能,可以将它广泛应用与建材、园艺、食品饮料、耐火保温材料、化工、石油等部门,应用领域越来越广,还在继续扩大;
3、粘土作为陶粒生产最优原料之一,但因为破坏耕地,已经被国家明令禁止;页岩为原料生产工艺比粘土陶粒和粉煤灰陶粒复杂,页岩需要进行开采然后粉磨,烧胀温度要高出粘土陶粒200℃甚至更高,因此页岩陶粒生产成本最高;其次烧结陶粒浪费能源,而且在烧制过程中排放燃料废弃物,造成环境污染。以粉煤灰为原料生产免烧高强陶粒,能够节约资源、降低成本;
4、截至2011年,中国城市固体生活垃圾存量已达70亿吨,可推算建筑垃圾总量为21亿至28亿吨,每年新产生建筑垃圾超过3亿吨。然而,绝大部分 建筑垃圾未经任何处理,便被施工单位运往郊外或乡村,露天堆放或填埋,耗用大量的征用土地费、垃圾清运费等建设经费。同时,清运和堆放过程中的遗撒和粉尘、灰砂飞扬等问题又造成了严重的环境污染。
5、申请号为200110012911的中国专利《具有表面反应活性的高强轻集料及其制备方法》中提出利用石灰石粉、黏土、萤石粉和石膏粉等原料制作出粒径为5-25mm的轻集料,堆积密度为850kg/m 3,筒压强度达到6MPa,堆积密度/筒压强度为141.67。该方法制作的轻集料使用了黏土,筒压强度较高,但不轻质。
6、申请号为201210282957.0的中国专利《一种陈腐垃圾渣粉、粉煤灰陶粒及其制造方法》中提出利用陈腐垃圾粉料粉煤灰和煤粉等原材料制出轻集料,堆积密度759kg/m 3,筒压强度5.2MPa,堆积密度/筒压强度为145.96。该方法制作的轻集料堆积密度偏高,筒压强度较低,烧结温度在1200—1280℃,烧结时间2-3小时,浪费能源。
7、申请号为2015096493.1的中国专利《一种粉煤灰包覆污泥陶粒及其制备方法》中提出以污泥为原材料,以页岩、长石粉、发泡剂为辅料制备污泥陶粒,采用包覆的方式防止陶粒粘结,堆积密度554-800kg/m 3,筒压强度3-6MPa,堆积密度/筒压强度为133.33—184.67。该方法制作陶粒,筒压强度偏低。
引用专利:
1、申请号为201110143190.9的中国专利《复合、保温、防火墙体材料用轻骨料及其生产方法》中提出一种包覆的生产方法,包括骨核,骨核外面包覆有中间层,中间层外面包覆有壳层。
目前陶粒存在的问题有:
1、低密度等级轻集料筒压强度低,筒压强度较高的轻集料堆积密度较高;
2、产品性能不稳定,在一定范围内波动;
3、烧结温度偏高,能耗大。
