1前言瓷质抛光砖是目前建陶市场上最为流行的墙地砖产品,深受用户的欢迎,但是目前我国的抛光砖主要出自广东和上海附近地区,而广大的北方地区由于原材料等原因,生产抛光砖的厂家很少。为了满足市场的需要,我们用山东省及其附近地区的原料,加入部分黑泥,成功研制生产出高档抛光砖产品,为企业创造了明显的经济效益,为我国北方地区生产优质瓷质抛光砖提供了经验。2瓷质抛光砖的工艺要求一般说来,理想的瓷质抛光砖坯体配方要满足如下要求:(1)合适的烧成温度,一般在1170~1230℃;(2)较宽的烧成范围;(3)较小的烧成收缩;(4)… 相似文献

陶瓷废料的组成与火山灰活性研究 总被引:2,自引:0,他引:2
摘要:通过X射线衍射分析、玻璃相含量测定、28d抗压强度比及火山灰活性等试验,研究了陶瓷玻化砖废料、瓷质废料、炻质废料和陶质花盆四种类型陶瓷废料的组成与火山灰活性,为开拓陶瓷废料的应用提供依据。研究结果表明:陶瓷抛光砖粉与废陶瓷玻化砖尽管主要成分相近,但前者氯含量较高,用于水泥混合材受到限制;几种类型的陶瓷废料均具有火山灰活性,其水泥胶砂28d抗压强度比均高于62%,废陶瓷玻化砖为82.1%,瓷质废料为80.8%,炻质废料为78.3%,陶质废料为77.3%。陶瓷玻化砖废料的玻璃相含量较高,瓷质废料其次,炻质和陶质废料的玻璃相含量较低。玻璃相含量较高的陶瓷废料其水泥胶砂28d抗压强度比.较高。 相似文献

Granite waste is by-product from a decorative rock industry. The present study aims to investigate the effect of muscovite granite waste on the physico-mechanical properties of ceramic tiles to demonstrate its suitability for industrial production. A series of flooring- and facing ceramic tiles were prepared by adding 20, 25, and 30 wt% muscovite granite waste into the batch compositions. The sintering behavior and degrees of densification of two kinds of ceramic tiles were evaluated by determining their physico-mechanical properties and characterizing them by scanning electron microscopy (SEM) and X-ray diffraction (XRD), respectively. As expected, the facing ceramic tile (FacCT1) sample, containing wollastonite, hematite, anorthite, quartz, and cristobalite, with 20 wt% muscovite granite waste showed lower physico-mechanical properties than those of the flooring ceramic tile (FloCT3) sample, containing mullite, calcium aluminosilicate, quartz, and cristobalite, with 30 wt% muscovite granite waste. The reason is that lower firing temperatures cannot accelerate a complete fusion of the granite waste which behaves like an inert non-plastic material similar to quartz. These results illustrate the prospects of utilizing muscovite granite waste in ceramic tile production. 相似文献

This study aims to develop a new approach for the permanent sealing of surface pores on polished porcelain stoneware tiles, using ceramic frits for the filling pores, followed by laser-sealing to ensure the fixation of the applied material. The laser-sealing parameters compatible with the ceramic substrate were focus height (z) of 105 mm, scan speed (v) of 2640 mm.min−1, and power values of 750, 800, and 850 W. In order to define the working parameters, three ceramic frits with 30, 50, and 70 wt.% solid contents were tested by sealing at the mentioned powers. High stain resistant polished stoneware tiles were obtained using frit 1 and frit 3 with 50 and 70 wt.% solid contents, respectively, and the proposed procedure. High ease of cleaning is obtained related to the current treatment, demonstrating its suitability for improving the stain resistance for meeting the ISO 13006:2012 requirements. 相似文献
