Description
技术领域
本发明涉及粘土陶瓷制品，特别是多孔陶瓷制品及其制法，同时还涉及污水的处理，属于资源环境领域。
背景技术
糖滤泥是制糖澄清过程中产生的固体废弃物，是制糖工业大宗副产品之一，糖厂每生产1吨糖要排出约1吨的滤泥。我国制糖业基本上采用碳酸法和亚硫酸法两种工艺。因为碳法糖的质量比亚法糖质量好，售价高，是制糖生产的首选方法，但碳法糖滤泥(以下简称糖滤泥)为强碱性滤泥，长期以来被直接用于肥田或废弃，这些滤泥的堆放，除占用大量的土地外，对环境产生了严重的污染。传统的滤泥处理方法为适度发酵后做农肥，长期使用会碱化和板结土壤。多个糖厂曾试验将少量滤泥与水泥厂的原料混合烧制水泥，但滤泥中的含氮物在焙烧时生成恶臭的气体，造成二次(大气)污染，无法实行。所以到目前为止，还未发现糖滤泥有效的处理方法。
发明内容
本发明的目的是以糖滤泥为主要原料烧制抗压强度较高、孔径较小且分布均匀的多孔陶瓷材料，生产工艺简单，糖滤泥不需特殊处理即可满足工艺要求，不仅解决了糖滤泥处理的环保问题，使其变废为宝，改善环境，而且大大降低了多孔材料的生产成本。具有良好的社会效益和经济效益。
本发明为实现目的所采用的技术方案是：把晾干的糖滤泥与粘土混合，其原料配比的质量百分比范围为：糖滤泥25％～50％，粘土50％～75％，在1000℃～1200℃下烧结10～40分钟。
碳法糖滤泥的主要成分是碳酸钙。此外还含有镁、铁、铝、硅等氧化物及有机物。在煅烧的过程中碳酸钙分解放出二氧化碳气体，滤泥中的有机物碳化和燃烧也产生一定量的气体，且在一定的煅烧时间与煅烧温度内反应趋于完全，这样可使其烧结制品具有一定的孔隙率，因此糖滤泥可以作为多孔陶瓷材料的发泡剂。粘土具有一定的可塑性，且主要成分为铝、硅等氧化物，皆为成瓷的基本成分，将二者混合，在一定的工艺条件下烧结，随着温度升高，体系内发生反应可以生成石英晶体、莫来石晶体和钙长石晶体，形成多孔陶瓷材料。
本发明的有益效果是生产工艺简单，解决了糖滤泥处理难的问题，且降低了多孔陶瓷材料的生产成本。制备的多孔陶瓷材料的性能优越，可用于多个领域。
附图说明
图1为滤泥的XRD分析图谱(图中★代表碳酸钙的衍射峰)；图2为烧成多孔陶瓷的XRD分析图谱(图中★代表石英的衍射峰；图中
代表莫来石的衍射峰；图中◆代表钙长石的衍射峰)；图3(×200)、图4(×1500)、图5(×4000)为不同放大比例下多孔陶瓷的微观结构图，即SEM图。
具体实施方式
所用滤泥的矿物成分见附图1，所用的粘土化学成分见表1。
表1 粘土化学成分/％质量百分数
实施过程如下：
1.对糖滤泥进行预处理：采用摊晒方法干燥糖滤泥，使含水率达到13％以下从而适合存放的要求。
2.按三种不同质量比例即糖滤泥：粘土＝1：1，1：2，1：3设计多孔陶瓷的配方进行称量，其编号依次为d-1、d-2、d-3，球磨一定时间混合均匀后，滤泥和粘土研磨过120目筛，卸料，加适量水反复揉练直到可塑性达到一定要求，形成可塑性泥料后陈腐一定时间。
3.将可塑性泥料制成35×35×10mm的模块或直径为30-40mm的球，以35×35×10mm的模块为例来评价其性能(结果见表2)，干燥后以一定的升温速率在1000℃～1200℃下烧结10～40分钟来完成多孔陶瓷材料的烧成。
表2 试样的烧成性能
烧成的多孔陶瓷XRD图谱见图2，多孔陶瓷中生成了一定量的莫来石晶相，钙长石晶相和石英晶相。二者为陶瓷中的常见晶相，莫来石晶体硬度大，稳定性好，晶体呈交织簇状分布，可大大提高了陶瓷的抗压强度和抗折强度。板状的钙长石晶体提高了陶瓷的抗压强度。高硬度的石英晶体也保证了陶瓷的机械强度。
图3、4、5为不同放大比例下多孔陶瓷的微观结构，观察图3和4可看出，陶瓷内孔分布均匀，形成了网孔状结构。而且在图4中可以清晰地看到陶瓷的孔隙结构明显，交联度较大，在图5中可以看到陶瓷中气孔的孔径尺寸范围为<5μm。以上结果证实了利用滤泥与粘土烧结可以烧成多孔陶瓷。制的多孔陶瓷材料最后得到主晶相为莫来石、石英和钙长石，陶瓷孔径尺寸为小于5μm，孔隙率为20～27％，吸水率为14～18％，机械强度为18～26MPa，该多孔陶瓷可用于废水的过滤和分离，载体材料、吸音和隔音材料等。
烧成过程中化学反应式如下：
1)高岭石脱水形成偏高岭石
Al2O3·2SiO2·2H2O→Al2O3·2SiO2+2H2O↑ (500℃-700℃)
2)石英的晶型转化
α-SiO2→β-SiO2 (573℃)
3)碳酸钙的分解
CaCO3→CaO+CO2↑ (800℃以上)
4)莫来石的生成
2Al2O3·2SiO2→2Al2O3·3SiO2+SiO2 (925℃)
3Al2[Si2O3](OH)4→3Al2O3·2SiO2+4SiO2+6H2O↑ (1000℃)
5)钙长石的生成
CaO·SiO2+Al2O3·2SiO2→CaO·Al2O3·2SiO2+SiO2 (900℃-1000℃)
CaSiO3+Al2O3·2SiO2·2H2O→CaO·Al2O3·2SiO2+SiO2+2H2O↑ (1000℃)。
