前言辊道烤花窑,经过我国窑炉工作者十几年的不断改进、完善,性能及结构都有了很大的提高。实践证明:辊道烤花窑较之传统隧道烤花窑有彩烤温度均匀,通风性能好,生产周期短,铅镉溶出量低,节约能源,产品质量高等优点。但各地辊道窑大多数均采用重油或煤气作燃料,而煤烧辊道烤花窑正式投入生产是一九八二年十一月的事。由于 相似文献

详细介绍了40m燃气辊道烤花窑的整个设计过程。说明了烤花窑设计中应重点考虑的几个关键问题—彩烤温度曲线及其确定方法和高温带烧嘴的设置等。阐述了一种长链分段传动的新形式,该传动形式既保留了链传动造价低,使用维护方便的优点,又克服了长距离链传动平稳性差的缺点,经实际使用证明是一种很好的新型结构。 相似文献

日用陶瓷制品及其装饰材料中Pb、Cd溶出量早已引起世界各国的高度重视,ISO国际标准化组织在1981年就制定了限制陶瓷器皿Pb、Cd溶出量的标准。实践证明,影响陶瓷制品及其装饰材料中Pb、Cd溶出量的因素很多,归纳起来大概有如下几种:一烤花窑的类型对Pb、Cd溶出量的影响,辊道烤花窑比园筒形的“红炉”和隧道式“锦炉”烧烤的陶瓷制品Pb、Cd溶出量低。三不同 相似文献

The advent of digital decoration has changed the technological requirements of colorants and the way they are applied onto ceramic substrates. This technological revolution has introduced additional steps in colorant production (ink micronization) and new constraints in application (ink-jet printing) that cannot be reproduced in a standard ceramic laboratory, so stretching the distance between academic and industrial research. The goal of this work is to provide an up-to-date picture of ceramic pigments, dyes and effects, with emphasis on their behavior in the current decoration technologies, which are shortly reviewed. Technological performance expected for ceramic colorants and new requirements imposed by digital decoration are discussed in detail. An extensive overview of both industrially used and candidate pigments, dyes and effects is focused on the suitability to different ceramic applications and firing conditions. Finally, lines of future research are outlined and commented. 相似文献

釉下彩是瓷器釉彩装饰的一种,又称"窑彩"。釉下颜料本是陶瓷器的一种主要绘画颜料,但本文改变它惯有的装饰手法,与浮雕艺术瓷结合,高温一次烧成。烧成后的图案被一层透明的釉膜覆盖在下边,表面光亮柔和、平滑不凸出,还可再釉上加彩。在制作过程中,从装饰技法、工艺流程和技术上创新,替代大部分颜色釉的不稳定性和流动性等不良弊端,更好地呈现浮雕瓷的空间和艺术效果。 相似文献

The provenance of cobalt mineral of the blue decoration in Yuan Qinghua porcelain would reveal the technological and cultural interaction between ancient China and the Islamic world. However, the limitation of conventional methods in the determining trace elements of the blue decoration hampered the deep research on provenance of the cobalt mineral. In the paper, we employed the good advantage of Laser-ablation-inductively-coupled-plasma-mass-spectroscopy (LA-ICP-MS) to determine the major element and trace elements of blue decoration of the different type of Qinghua successfully. The blue decoration of all different types of samples shared the same characteristics of higher FeO and lower Mn, which suggested the potter adopted the non-native cobalt material of China to paint the Yuan Qinghua in Jingdezheng, and the difference on the outside appearance of blue decoration of different samples were supposed to be related to the tenor of ore, the different treatment process of cobalt material and the firing process in the kiln. In addition, the significant differences on the element concentrations of Cu, Ni, Pb, Zr and Sb in the blue decoration between Yuan Qinghua and the Islamic blue and white wares of 13–14th century provided a new evidence to discuss the provenance of the cobalt of Yuan Qinghua porcelain. 相似文献
