Abstract

The humidity regulation in the interior spaces of buildings by means of passive solutions that do not require energy consumption is a topic of great interest due to the current needs for comfort and energy efficiency. This paper addresses the engineering of humidity regulating ceramic tiles that incorporate a functional coating formulated from gibbsite together with other common raw materials whose moisture regulating capacity has been demonstrated previously. A multi-layer coating tile system has been proposed, consisting of the following elements: an engobe layer, the functional coating with the regulating capacity, a decoration by inkjet technology and a protective topcoat glaze.

This system has been analysed with moisture adsorption–desorption tests. The moisture regulation capacity and the effect of the coating thickness on this property have been determined, allowing to optimise the functionality.

Finally, an analysis of the humidity regulation has been performed on the basis of demonstrators or small-sized cubicles that simulate the conditions of final use in rooms of buildings. The results show the different behaviour of the demonstrator with functional tiles in relation to conventional tiles, with an indoor ambient humidity that remains in the comfort zone for longer periods of time.

具有湿度自我调节功能的陶瓷砖的工程设计和规模化生产

由于当前对舒适度和能源效率的需求，通过无需消耗能源的被动式解决方案来调节建筑物内部空间的湿度是一个备受关注的话题。本文论述了湿度调节瓷砖的工程设计，这种瓷砖结合了由吉布斯特和其他常见原材料配制而成的功能性涂层，这些原材料的湿度调节能力已在之前得到证实。本文提出了一种多层涂层瓷砖系统，由以下元素组成：水泥层、具有调节能力的功能涂层、喷墨技术装饰和保护性面釉。最后，在模拟建筑物房间最终使用条件的演示器或小型隔间的基础上，对湿度调节进行了分析。结果表明，使用功能性瓷砖的样板间与使用传统瓷砖的样板间表现不同，室内环境湿度在较长时间内都保持在舒适区域。

期刊介绍： The Journal of the Spanish Ceramic and Glass Society publishes scientific articles and communications describing original research and reviews relating to ceramic materials and glasses. The main interests are on novel generic science and technology establishing the relationships between synthesis, processing microstructure and properties of materials. Papers may deal with ceramics and glasses included in any of the conventional categories: structural, functional, traditional, composites and cultural heritage. The main objective of the Journal of the Spanish Ceramic and Glass Society is to sustain a high standard research quality by means of appropriate reviewing procedures.
