Color matching algorithms in ceramic tile production

In the present work, the possibility of transferring in the ceramic tiles production the know-how developed in the field of the paints by using the Kubelka–Munk theory, in the form used for opaque surface coatings, have been evaluated. Five different target colors have been chosen as target and tried to reproduce with an industrial glaze in a cycle for fine porcelain stoneware tiles. Four industrial pigments have been chosen as basic stains for the formulations. The results show a good efficiency of the color matching algorithm applied to pigments for glazes for fine porcelain stoneware tiles. All the formulations, in fact, have allowed to obtain a value of ΔE^* lower to the accepted limit.     

无釉砖和有釉砖耐磨性标准的统一化探析

耐磨性是陶瓷砖的一项关键性能指标,目前GB/T 4100—2015《陶瓷砖》规定无釉砖和有釉砖采用不同的试验方法。利用耐深度磨损试验机、陶瓷砖釉面耐磨试验机和Taber试验机对无釉砖和有釉砖进行耐磨性的测定,研究同一种试验方法是否能同时对两种陶瓷砖作精确的评判。结果表明,无釉砖耐磨深度法和Taber耐磨试验法可通过磨损体积的大小对无釉砖进行耐磨性的测定,但两者都不适合用于有釉砖耐磨性的测定。有釉砖表面耐磨法用磨耗质量大小取代目视评价可得到更客观和精准的结果,可同时用于无釉砖和有釉砖耐磨性的测定。     

Determination of the moisture diffusivity coefficient and mathematical modeling of drying

Drying plays an important role in the production of clay tiles. In the present article, drying process is analyzed taking experimental data for several masonry clays obtained from different clay tile manufacturers and published data for different clay slabs. Calculation methods and computer programs designed for the calculation of the effective diffusion coefficient are developed. The first calculation method represents the analytical solution of the Crank equation, while the second one represents the analytical solution of the Efremov equation with boundary conditions in the form of the flux. Unlike other materials, clay tiles exhibit shrinkage during the drying process. For this reason, a shrinkage correction is included in both calculation methods. Four models (A1, A2, B1 and B2) for predicting the drying behavior are obtained as the result of the calculation cited programs. It is shown that the calculated effective diffusion coefficient determined by the designed computer programs, using experimentally obtained and selected published data sets have similar values to those of the same coefficient reported in the literature. Based on the mathematically determined prognostic values of the effective diffusion coefficient, it was concluded that there is more than 90% agreement between the experimentally recorded and the calculated drying curves.     

Bending strength of porous ceramics tiles: Bounds and estimates of effective properties of an Intermingled Fractal Units’ model

In this work, a semi-analytical model for the determination of effective mechanical properties of porous ceramic tiles obtained by pore forming agent is proposed. MIP tests allow measuring porosity and pore size distribution of experimental systems. These data are used for developing an Intermingled Fractal Units’ model (IFU) as approximant of porous microstructures. IFU model is then combined with classical structural mechanics theory for the analytical computation of the bending strength of brittle ceramic beams. Bounds and estimates are given in full form and the detailed algorithm can be easily implemented in a numerical package. A preliminary comparison with experimental data shows the capability of the proposed model to reproduce the effective mechanical behaviour of ceramic tiles.     

Computer generated time & distance values of nutrient constituents with applications to timed-release capsules

The diffusion equation for infinite cylindrical sources has been solved for the boundary conditions appropriate to timed-release fertilizer pellets. The solution was tested against experimental results of the distortion of the image of a grind illuminated by laser light and recorded on video tape. The optical theory was examined for validity using Fermat's Principle. A computer program was developed to predict concentration as a function of time and distance with sufficient flexibility to allow for multiple sources and any other variation which can be accounted for by change of diffusion coefficient.     

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.

再现自然——仿古砖艺术设计的本质

仿古砖与抛光砖、瓷片相比，它更接近于“自然”的状态。仿古砖的艺术设计就是追求自然，追求一种自然的状态，而这种追求暗合了中国人的审美观念与自然观，因此再现自然是仿古砖艺术设计的本质。一切与“自然”有关的物质或非物质，都是仿古砖设计的方向和表现对象与内容。
