用长江入海口淤泥研制室内装饰釉面砖

Production of interior glazed tiles with the Yangtze River silt of sea entrance

利用长江口淤泥研制室内装饰釉面砖,以达到废物综合利用,同时降低釉面砖生产成本的目的。采用了扫描电镜(SEM)和X射线衍射分析(XRD)等探测手段,对制品烧成过程中的质点扩散、固相反应、相变过程进行了探讨和研究,阐明了宏观性能与显微结构之间的关系。研究表明随着温度的升高,制品的密度增加,强度也相应的提高;莫来石的含量有一个产生→降低→升高的过程。研究的室内装饰釉面砖,满足相应国家标准的要求。

Silt at the bottom of the Yangtze River is made into glazed tiles, the waste is recycled in a comprehensive way, and the cost of producing glazed tiles is reduced. XRD and SEM are used to detect solid-diffusion, solid reaction and phase transformation, and the relation between macronature and microstructure is il-Iminated. The study shows that increase of temperature results in increase of density, intensity, and the content of mulite first decreases, then increases with the increase of temperature. That is proved that the glazed tiles produced in this way can reach the relevant national standard.
