摘要
针对"唐山骨质瓷"地理标志产品独特的原料配比和烧成工艺,选取5家不同企业生产的10.5吋白瓷平盘作为实验样品。在室温条件下,分别使用盐酸、硫酸、柠檬酸和醋酸4种不同浓度的酸性溶液对样品釉面持续作用10h后,测试其白度和光泽度,分析其变化趋势,并研究了骨质瓷釉面耐室温酸性试剂侵蚀性能的优劣。研究得出如下结论:骨质瓷经酸蚀后釉面质量呈现不同程度的下降且其承受不同酸性试剂侵蚀的性能存在显著差异,其中耐强酸腐蚀性相对薄弱,耐弱酸腐蚀性各不相同;同一企业的样品耐酸蚀性能相近,但同一样品釉面光泽度的变化较白度变化大;不同企业的样品耐酸蚀性能各异。
This paper according to the requirements of the unique production process of the tangshan bone China geographic indication products, specified 36 pieces of bone China 8 inch flat produced by 6 different factories as the experimental sam- ples. After using 6 kinds of chemical reagents such as acid, alkali, salt, stain and disinfectant eroded continuously on the a- bove samples glaze for a certain period of time Under the given conditions of temperature and humidity, tested glaze white- ness and gloss of samples qualitatively. By measuring the changes of whiteness and luster after glaze erosion of samples, analyzed degree of the erosion quantitatively. Derived the following conclusions: the strength of glaze corrosion caused by different chemical reagents to bone china samples produced from the same factories were different. The corrosion effect of alkali is stronger than that of acid, and the corrosion effect of stain is stronger than that of salt and disinfectant for bone china glaze white and glossiness. The corrosion effect of each chemical reagent used for bone china samples produced by dif- ferent factories is different. The corrosion effect of each chemical reagent is different for bone china samples produced by different factories. Due to different measurement principle, the rangeability of bone china glaze whiteness and luster with the glaze state changes is different.
