In this article, glaze with different colorants was applied to tile specimens manufactured by incinerated sewage sludge ash (ISSA) and clay. Improvements using different amounts of colorants, and glaze components and concentrations on tile bodies were investigated. Four different proportions of clay (by weight ratio) were replaced by ISSA. Tiles of size 12 cm x 6 cm x 1 cm were made and left in an electric furnace to make biscuit tiles at 800 degrees C. Afterwards, four colorants, Fe2O3 (red), V2O5 (yellow), CoCO3 (blue), and MnO2 (purple), and four different glaze concentrations were applied on biscuit tile specimens. These specimens were later sintered into glazed tiles at 1050 degrees C. The study shows that replacement of clay by sludge ash had adverse effects on properties of tiles. Water absorption increased and bending strength reduced with increased amounts of ash. However, both water absorption and bending strength improved for glazed ash tiles. Abrasion of grazed tiles reduced noticeably from 0.001 to 0.002 g. This implies glaze can enhance abrasion resistance of tiles. Effects like lightfastness and acid-alkali resistance improved as different glazes were applied on tiles. In general, red glazed tiles showed the most stable performance, followed by blue, yellow, and purple.
在本文中，将含有不同着色剂的釉料施用于由焚烧污水污泥灰（ISSA）和粘土制成的瓷砖试件上。研究了使用不同用量的着色剂以及釉料成分和浓度对瓷砖坯体的影响。用ISSA替代了四种不同比例（按重量比）的粘土。制作了尺寸为12厘米×6厘米×1厘米的瓷砖，并将其置于电炉中在800摄氏度下烧制制成素烧瓷砖。之后，将四种着色剂，即Fe2O3（红色）、V2O5（黄色）、CoCO3（蓝色）和MnO2（紫色），以及四种不同的釉料浓度施用于素烧瓷砖试件上。这些试件随后在1050摄氏度下烧结成釉面瓷砖。研究表明，用污泥灰替代粘土对瓷砖性能有不利影响。随着灰分含量的增加，吸水率上升，抗弯强度下降。然而，釉面灰瓷砖的吸水率和抗弯强度均有所提高。釉面瓷砖的磨损量从0.001克显著降低至0.002克。这意味着釉料可以提高瓷砖的耐磨性。当在瓷砖上施用不同釉料时，诸如耐光性和耐酸碱性能等有所改善。总体而言，红色釉面瓷砖表现出最稳定的性能，其次是蓝色、黄色和紫色。
