抛光砖废渣由于有害杂质过多,因此在废物再利用技术上存在诸多困难。探讨了利用陶瓷抛光砖废渣生产广场砖的工艺技术。实验结果表明,在抛光砖废渣添加量达23.64%的情况下,通过调整工艺配方提高广场砖配方的始熔点,以此减少坯体中的气孔。制备出的广场砖具有较优的性能,并符合国家标准。 相似文献

以固体废弃物粉煤灰与K2CO3为主要原料,通过预烧处理得到活化的粉煤灰原料,分别在850 ℃、875 ℃、900℃、925℃、950℃度进行常压烧结,制备得到粉煤灰陶瓷墙地砖材料.利用XRD、SEM分别对其物相组成与微观结构进行测试,结合烧成样品的吸水率、体积密度、显微硬度随温度的变化规律,分析了烧结工艺对粉煤灰陶瓷墙地砖性能的影响.研究结果表明:随着烧结温度的升高,样品中液相含量明显增加,在液相流动的作用下,坯体内部的气孔逐渐被填充,固相颗粒被粘结在一起形成连续的整体,从而形成致密的瓷体结构,当烧结温度为925 ℃时,样品的吸水率达到最小值:0.07%,维氏硬度达到最大值:5.9 GPa.而保温时间的增加,液相流动与物质迁移更充分,导致KAlSiO4晶粒尺寸增加,轮廓清晰,但并未对物相及其力学性能产生明显影响. 相似文献

将废弃瓷砖破碎为再生粗、细骨料及粉料,全组分制备再生混凝土.采用室内模拟酸雨侵蚀试验,研究不同pH值酸雨侵蚀条件下废瓷砖再生骨料、废瓷粉掺合料对混凝土中性化的影响.研究结果表明:与原生碎石混凝土相比,废瓷砖再生粗骨料混凝土的抗压强度较高,经酸雨侵蚀后的中性化深度最小;掺入废瓷砖粉的再生混凝土抗压强度随废瓷砖粉掺量的增加而降低,中性化深度随废瓷粉掺量的增加而增大.在相同酸雨侵蚀条件下,与原生碎石混凝土相比,废瓷砖再生混凝土的化学结合水含量较低,内部显微结构更致密. 相似文献

Due to the large amount of ceramic tile polishing waste generated in China, the recycling of this waste residue becomes important. Herein a foam ceramic was successfully produced by using ceramic tile polishing waste as main raw material. In this research, SiC was added as the foam agent, and the foaming mechanism was also investigated. The results showed that the best dosage of SiC was 1%. Furthermore, in order to obtain a foam ceramic with better structure, the sodium phosphate was added in raw materials as foam stabilizer. The influence of this addition on the microstructure and properties of foam ceramic was investigated. It was found that the optimum additive amount of sodium phosphate is 2–3%. 相似文献

陶瓷抛光废料对多孔陶瓷砖气孔形成过程影响的研究 总被引:2,自引:1,他引:1
本文以陶瓷抛光废料为主要原料,研制了以石英和莫来石为主晶相的多孔陶瓷轻质砖,采用XRD、显微镜分析了陶瓷抛光砖废料对其气孔形成过程的影响,探讨了影响其气孔形成的主要因素。研究结果表明,陶瓷抛光砖废料由于含有机物和无机盐,可作为成孔剂,在400-700℃温度范围,有机物分解形成小气孔,随着温度的升高,以钙镁碳酸盐为主的无机盐在900℃左右分解,所形成的气孔由小变大;影响多孔陶瓷轻质砖气孔形成的主要因素是原料配方和烧成制度。 相似文献

Boron mining and enrichment waste (BW) from boric acid (H3BO3) production is a by-product of the boron industry. BW exhibits B2O3 contents of 16-31 wt%, and therefore, could be used to effectively lower the sintering temperature of ceramics without increasing their thermal expansion coefficient. Herein, we introduced 3-10 wt% of BW to a formulation used for commercial porcelain tile production, and achieved a sintering temperature decrease of 38°C (to 1195°C). The resulting porcelain tiles exhibited a strength of 44.80 MPa and water absorption percentage of 0.01%, and therefore, met TS ISO EN 10545 requirements. Thus, this study paves the way for the use and valorization of BW in the production of porcelain tiles and could inspire the search for other opportunities to utilize BW in ceramic production. 相似文献

Reusing the waste products generated in ceramic manufacturing is an environmentally responsible and sustainable approach. This study aims to protect natural resources, minimise raw material costs and manage waste-generated pollution by reusing the vitrified sanitaryware waste (VSW) products from Canakkale Kalebodur Seramik San. A. S. Six sample formulations were prepared under industrial conditions and compared with a standard tile body. The results indicated that using VSW in place of feldspar results in an increased firing shrinkage and decreased bending strength, whereas using VSW in place of pegmatite results in an increased bending strength and reduced thermal expansion coefficients. The reduction in the thermal expansion coefficients is an important finding that aids in meeting the dimensional and deformation requirements of porcelain tiles and also results in a slight lightening of the tile colour. This study shows that the fired VSW products can be used in glazed porcelain tile production as a sustainable and technologically, economically and environmentally suitable approach. 相似文献
