Description
技术领域
本发明属于陶瓷材料制备技术领域,具体涉及一种新型陶瓷材料。
背景技术
长期以来陶瓷器皿深受广大人民群众所喜欢,他们具有很多优点:第一、热稳定性好,传热慢;第二、化学稳定性好;第三、易于洗涤和保持洁净;第四、吸水率低。目前,陶瓷产品的价格较高,制作陶瓷的原料也比较缺乏,需要寻找新的原料。
在我们的社会上又另外存在着一种大量增加着的还没有得到有效利用的废料—污泥,据2010年发布的“第一次全国污染源普查公报”指出:我国污水处理厂污水年实际处理量为210.31亿吨,“十一五”期间,我国新增污水处理能力超过5000万吨每日,全国污水处理率由2005年的52%提高到75%以上。目前我国每年产生的干污泥为900万吨,并且每年以10%以上的速度递增。虽然污泥是较好的农业肥料,其中氮、磷、钾含量远高于农家肥,但污泥还有寄生虫,病菌等,臭味问题尤其突出,如果用污泥肥田肥林,农民无法忍受其气味,不愿意接受。况且农业生产有季节性,污泥堆肥受到季节和销售半径的明显影响,即使没有臭味等问题农林业利用也无法全部消纳城市产出的污泥。所以到现在以上还没有给污泥找到出路,仍然处于废料的地位,在2011年3月28日得科技日报上发表了“污水处理了,污泥咋办?”的文章,呼吁社会各界来关心污泥处理的问题,摆在我们面前的问题是如何将污泥在陶瓷上得到利用。
发明内容
本发明要解决的技术问题是提供一种新型陶瓷材料,以解决现有陶瓷产品价格较高,制作陶瓷的原料也比较缺乏;以及污泥如何有效利用等问题。采用本发明的新型陶瓷材料制成的陶瓷击穿强度好;本发明为污泥废料、农作物秸秆开辟了利用的领域,有效降低本制作陶瓷成本、节约能源消耗,实现了变废为宝。
为了解决以上技术问题,本发明采用以下技术方案:
一种新型陶瓷材料,以重量份为单位,包括以下原料:干污泥45-85份、农作物秸秆35-48份、锂霞石10-24份、透锂长石10-22份、硅藻土10-16份、氧化锌8-12份、二氧化硅6-10份、氧化钡6-12份、铝碎块4-6份、玻璃纤维2-3份、减水剂2-3份、发泡剂0.6-1.2份、发泡调节剂0.4-1份、催化剂0.4-0.6份、交联剂0.4-0.6份、稳泡剂0.2-0.4份、双氧水30-40份、水380-480份。上述原料中的污泥可以是生活污水处理中得到的污泥,也可以是工业污水处理中得到的污泥或者生活和工业混合污水处理中得到的污泥,污泥中含有机物和重金属,污泥需要通过预处理,即除水,除臭,除有机物和分离重金属。
所述新型陶瓷材料的制备方法,包括以下步骤:
S1:将干污泥、农作物秸秆、锂霞石、透锂长石、硅藻土、氧化锌、二氧化硅、氧化钡、铝碎块、玻璃纤维放入粉碎机中,在转速为400-800r/min下粉碎2-3h,制得复合粉体;
S2:将步骤S1制得的复合粉体放入球磨机中,在转速为500-600r/min下球磨处理1-2h后过200-300目筛子,制得粉末;
S3:将步骤S2制得的粉末和减水剂、发泡剂、发泡调节剂、催化剂、交联剂、稳泡剂、双氧水、水在温度为,转速为100-120r/min下搅拌4-5h,制得浆料;
S4:将步骤S3制得的浆料在真空度为0.85-0.95下,抽真空15-20min,制得毛坯件;
S5:将步骤S4制得的毛坯件在60-70℃下进行微波处理,处理时间为10-20min,随后在1250-1300℃下进行烧结,烧结时间为20-25h,制得新型陶瓷材料。
进一步地,所述干污泥的含水量≤10%。
进一步地,所述农作物秸秆粉末的粒径≤300μm,水分含量≤14%。
进一步地,所述农作物包括玉米、水稻中的一种或多种。
进一步地,所述减水剂为聚羧酸减水剂。
