Obtainment of porcelain floor tiles added with petroleum oily sludge

This study focuses on the processing of vitrified floor tiles incorporated with a petroleum oily sludge. Floor tile formulations containing up to 5 wt% of the petroleum oily sludge in replacement of kaolin were prepared. The tile formulations were granulated by the dry process, pressed, and fired at temperatures between 1200 and 1250 °C using a fast-firing cycle. The specimens were characterized before and after firing. XRD was used to identify the crystalline phases present during sintering and SEM was used to show how the structure changes during densification. Three parameters were used to describe densification: linear shrinkage, water absorption, and flexural strength. The results showed that the petroleum oily sludge could be used as an alternative raw material in the floor tile formulations. The densification behavior of the floor tile pieces is influenced by the petroleum oily sludge addition and firing temperature. The vitrified floor tiles produced reached the technical characteristics of porcelain floor tiles, depending on petroleum oily sludge content and firing temperature.     

Acoustic and thermal performances of ceramic tiles and tiling systems

Acoustic and thermal performances of floating floor and/or radiant floor can be improved by using ceramic tiles with tailored porosity and microstructure. Porcelain stonewares are still the most widespread typology of tiles, due to their high physical and mechanical performances coming from a very low level of open porosity and water absorption (≤0.5 wt%). However their closed porosity values, usually neglected, can be significantly different from one product to another. As a consequence, the properties directly dependent on the total porosity, such as thermal and acoustic ones, may be strongly diverse among commercial tiles.Several commercial porcelain stoneware tiles having different composition, microstructure and porosity, were selected for the present work. These tiles, alone or coupled with different types of resilient underlayer materials (glass fibre, cork and rubber), were studied on the basis of dynamic stiffness. Their acoustic and thermal properties were investigated in terms of thermal conductivity and walking noise reduction.     

影响建筑地面与橡胶界面静摩擦问题分析

分析了法向载荷、陶瓷砖表面材料性质、表面干湿污染对建筑地面与橡胶界面静摩擦影响因素。研究表明,当法向荷载不断增大时,地面砖的摩擦系数也会随之增大,同时在材质不一样的砖面摩擦系数的变化也会有所差别,但总体上建筑地面与橡胶界面静摩擦系数是随着法向荷载的增大而增强的。特别要注意的是建筑地面表面的干湿因素,在一定的法向荷载下,表面干湿程度对地面砖的摩擦系数的影响不明显,甚至没有影响,但当法向荷载增大到一定程度的时候,表面干湿程度对建筑地面的摩擦系数影响尤其明显,该因素为正常人的体重荷载下对建筑地面与橡胶界面静摩擦性能影响的主要因素。     

陶瓷地砖静摩擦系数试验方法研究

静摩擦系数是评价陶瓷砖防滑性能的重要指标。本文分析了两种陶瓷砖摩擦系数试验方法(中国标准GB/T 4100-2006附录M以及美国标准ASTM C1028-07)的异同点,对8类的陶瓷地砖进行了静摩擦系数测试和防滑性能评价。测试结果显示,两种方法的测试值存在差异,滑块橡胶类型不同是产生差异的主要原因。对于抛光表面,用水平拖拉法测得的静摩擦系数可能不能反映其真实的防滑性能,应采用其他合适的方法测试和评价其防滑性能。     

Utilization of granodiorite in the production of porcelain stoneware tiles

In the present study, the use of granodiorite, as fluxing agent in a body mix for stoneware ceramic tiles production, was assessed. Four batches were formulated using clay from Khaboba, and natural granodiorite from Saint Katherine, Sinai, Egypt. The batches were tailored to completely replace both feldspatic and inert components of stoneware ceramic tiles. Densification was studied according to ISO rules, while sinterability was estimated by optical dilatometry. The dependence of microstructure and mechanical properties of stoneware ceramic tiles on granodiorite content was discussed. Strength measurements showed that increasing granodiorite content the bending strength of the bodies increased. In particular the studied batches can be used for the production of industrial fast firing tiles. The obtained ceramic tiles possess properties similar to commercial ceramic floor and/or wall tiles.

Stray Field Magnetic Resonance Imaging (STRAFI) of Water Transport in Ceramic Substrates

Measurements of water transport in ceramic tiles made using the stray field magnetic resonance imaging technique (STRAFI) are reported. STRAFI represents one method of accomplishing magnetic resonance imaging (MRI) of solids and confined liquids.Water was demonstrated to saturate a sample, cored from an unglazed wall tile, within 4 minutes of exposure. The sample was in constant contact with water at the upper surface and open to air at the bottom. The water ingress was characteristically Fickian in its dynamics. Samples cored from glazed wall and floor tiles were demonstrated to be waterproof (down to 50 m spatial resolution) up to 20 h. Water was shown to ingress samples from abraded, glazed floor tiles, in which the glaze layer was damaged. In this situation, a dynamic equilibrium was established between water entering the upper surface and evaporating from the bottom surface. A gradient of water content through the tile developed. These observations held not only for the abraded tiles, but also for certain household tiles of lower porosity than the unglazed wall tile.
