摘要
以工业废料粉煤灰、石英等为主要原料,研究了镁质粘土、烧滑石、黑滑石三种不同镁质原料对建筑卫生陶瓷制品红外性能的影响。通过XRD、红外发射率测量仪(IR-2)及常规测试等分析,结果表明:不同镁质原料的加入,样品中的主晶相皆为石英和莫来石,部分Mg2+固溶到莫来石晶格中,使得莫来石的晶胞体积膨胀发生晶格畸变;不同镁质原料的引入,其化学环境条件不同,导致各样品主晶相石英的晶格畸变程度不同,晶格畸变是添加镁质粘土>烧滑石>黑滑石,高红外发射率的卫生陶瓷中主晶相的晶格畸变是影响红外发射率变化的主要因素,畸变越大红外发射率越大。
The study researched the effect of the diHerent kinds of magnesian material, which are the magnesian clay, burnedtalc, black talc quartz on the infrared property of the construction sanitary ceramic, meanwhile, the quartz and industrial waste fly ash were taken as the body＇ s main raw materials. The XRD, infrared emissivity measuring and other convention testing were used throughout the analyzing. The result showed that the crystalline phases are only mullite and quartz in the body when the different magnesian material was added. Part of Mg2＋. would solid soluble in the crystal lattice of mullite what will cause the unit cell volume expanded and the lattice distorted. Different magnesian material caused the different degree of the lattice distortion of the main crystalline phase quartz. The lattice distortion of the main crystalline is the main factor what influences the infrared emissivity of the construction sanitary ceramic, the greater distortion the higher emissivity. The degree of the lattice distortion is the greatest when added the magnesian clay, and then the burnedtalc is.
