铝废渣制备青花日用陶瓷坯体的研究

Preparation of Porcelain Body with Waste Aluminum Residue

工业的迅速发展产生了大量的工业废料,在陶瓷工业中回收利用这些废料无论是对环境保护、资源能源的有效利用,还是对陶瓷行业的可持续发展都具有重要意义。本文首先介绍了铝型材工业废渣(简称铝废渣)产生和回收利用现状,然后通过X射线衍射(XRD)、扫描电子显微镜(SEM)对这种低品位原料的理化性能进行了测试分析。结果表明:铝废渣的适量加入不会对青花陶瓷坯体的组成造成不良影响,利用铝废渣中的杂质氧化物可提高瓷坯的外观品质、降低烧成温度。通过XRD和SEM得到坯体的物相组成和显微结构,铝废渣的掺入对青花陶瓷坯体的白度影响较小。实验中最大的掺入量达25%,当掺入量为15%时,坯体的吸水率最低,强度最高。

The rapid development has produced a lot of industrial waste. Recycling and reusing such waste in the ceramic industry are of great significance to the environmental protection, the effective using of resources and energy, and the sustainable development of ceramic industry. First, this paper introduced the generation of waste aluminum residue and its recycling. Then the physical and chemical properties of this low-quality raw material were tested and analyzed by XRD and SEM. It＇s proved that adding the right amount of waste aluminum residue did not cause adverse effects on body composition, the use of aluminum oxide impurities in the waste can improve the appearance quality of the porcelain body and lower its firing temperature. The body phase composition and microstructure were obtained by XRD and SEM, and adding waste aluminum residue had little effect on body whiteness. The highest adding amount in the experiment was 25%. When the adding amount was 15%, the water absorption was the lowest and the strength was the highest.
